<strong>WMO</strong> is a specialized agency <strong>of</strong> the<br />

United Nations.<br />

Its purposes are:<br />

To facilitate worldwide cooperation in the<br />

establishment <strong>of</strong> networks <strong>of</strong> stations<br />

for the making <strong>of</strong> meteorological observations<br />

as well as hydrological and other<br />

geophysical observations related to<br />

<strong>meteorology</strong>, and to promote the establishment<br />

and maintenance <strong>of</strong> centres<br />

charged with the provision <strong>of</strong> meteorological<br />

and related services;<br />

To promote the establishment and maintenance<br />

<strong>of</strong> systems for the rapid<br />

exchange <strong>of</strong> meteorological and related<br />

information;<br />

To promote standardization <strong>of</strong> meteorological<br />

and related observations and to<br />

ensure the uniform publication <strong>of</strong> observations<br />

and statistics;<br />

To further the application <strong>of</strong> <strong>meteorology</strong><br />

to aviation, shipping, water problems,<br />

agriculture and other human activities;<br />

To promote activities in operational<br />

hydrology and to further close cooperation<br />

between Meteorological and<br />

Hydrological Services;<br />

To encourage research and training in<br />

<strong>meteorology</strong> and, as appropriate, in<br />

related fields, and to assist in<br />

coordinating the international aspects <strong>of</strong><br />

such research and training.<br />

The World Meteorological<br />

Congress<br />

is the supreme body <strong>of</strong> the Organization. It<br />

brings together delegates <strong>of</strong> all Members<br />

once every four years to determine general<br />

policies for the fulfilment <strong>of</strong> the purposes<br />

<strong>of</strong> the Organization.<br />

The Executive Council<br />

is composed <strong>of</strong> 37 directors <strong>of</strong> National<br />

Meteorological or Hydrometeorological<br />

Services serving in an individual capacity; it<br />

meets at least once a year to supervise the<br />

programmes approved by Congress.<br />

The six regional associations<br />

are each composed <strong>of</strong> Members whose<br />

task it is to coordinate meteorological,<br />

hydrological and related activities within<br />

their respective Regions.<br />

The eight technical commissions<br />

are composed <strong>of</strong> experts designated by<br />

Members and are responsible for studying<br />

meteorological and hydrological operational<br />

systems, applications and research.<br />

In this issue<br />

Tourism is one <strong>of</strong> the world’s largest<br />

economic sectors and it is developing<br />

rapidly. For some countries, especially<br />

Small Island Developing States,<br />

it is the main source <strong>of</strong> income. In<br />

parts <strong>of</strong> the developed world, entire<br />

regions are economically dependent<br />

on the tourists who go there to visit<br />

or to practise sports.<br />

Francesco Frangialli, Secretary-General<br />

<strong>of</strong> the United Nations World<br />

Tourism Organization and himself a<br />

native <strong>of</strong> a winter sports area,<br />

responds to our questions concerning,<br />

inter alia, the impact <strong>of</strong> weather and<br />

climate on this important industry and<br />

the impact <strong>of</strong> <strong>tourism</strong> on climate and<br />

the environment.<br />

Tourism is the second most important<br />

economic activity in Mauritius<br />

and is, moreover, in constant growth.<br />

Its unsustainable development, however,<br />

may aggress the marine environment,<br />

while, conversely, a<br />

degraded coastal area may hinder the<br />

growth <strong>of</strong> <strong>tourism</strong>. Mohamudally Bee-<br />

beejaun explains how Mauritius is targeting<br />

an environmentally sustainable<br />

growth <strong>of</strong> <strong>tourism</strong>, which will include<br />

better preparation against natural hazards.<br />

This being achieved by a close<br />

relationship between the National<br />

Meteorological Service and <strong>tourism</strong><br />

managers.<br />

Barbados has a similar situation: a<br />

vital <strong>tourism</strong> industry, related environmental<br />

problems—notably coastal<br />

erosion—and a vulnerability to natural<br />

hazards, which exacerbate those<br />

problems. Four members <strong>of</strong> the<br />

Coastal Zone Management Unit<br />

describe their programme, which<br />

focuses on shoreline stabilization<br />

through the use <strong>of</strong> coastal engineering,<br />

water-quality monitoring, protection<br />

<strong>of</strong> coastal ecosystems and the<br />

control <strong>of</strong> development through strict<br />

planning guidelines. They work<br />

closely with meteorologists to<br />

improve predictions with respect to<br />

the potential impacts <strong>of</strong> rain, wind<br />

and wind-generated waves.<br />

Since its inception, air <strong>transport</strong> has<br />

been one <strong>of</strong> the main users <strong>of</strong> meteorological<br />

information. Pilots and airtraffic<br />

controllers need information on<br />

wind direction and speed, temperature,<br />

surface and upper winds, visibility<br />

and runway visual range. The<br />

International Civil Aviation Organization<br />

(ICAO) and <strong>WMO</strong> work closely<br />

together to ensure that aviation<br />

requirements can be met without<br />

unnecessary overlap <strong>of</strong> activities.<br />

O.M. Turpeinen sets out the working<br />

arrangements that are in place. He<br />

expects that the production <strong>of</strong> forecasts<br />

will become more efficient and,<br />

ultimately, will be fully automated.<br />

All marine vessels are highly vulnerable<br />

to weather and oceanic natural<br />

hazards. Henri Savina explains how<br />

marine safety information is gathered<br />

and provided under the overall coordination<br />

<strong>of</strong> the International Maritime<br />

Organization (IMO). Requirements <strong>of</strong><br />

maritime users have grown in<br />

response to change and innovation in<br />

ship design, economic and competitive<br />

pressures and increasingly<br />

sophisticated shipboard technology.<br />

He highlights some <strong>of</strong> the key issues<br />

for <strong>WMO</strong> and IMO in the future.<br />

Zhai Panmao and Yang Zhenbin discuss<br />

how the development <strong>of</strong> wind as<br />

a significant energy source is being<br />

managed in a proactive and sustainable<br />

way by the China Meteorological<br />

Administration. Major factors being<br />

taken into consideration are climate<br />

change and the prediction <strong>of</strong> wind<br />

energy and extreme weather conditions.<br />

Offshore structures are exposed to<br />

maritime hazards. Johannes Guddal<br />

explains how a well-developed plan<br />

<strong>of</strong> action, based on design preparedness<br />

and operations planning can be<br />

used by the <strong>of</strong>fshore industry to mitigate<br />

accidents and damage occurring<br />

from extreme weather and related<br />

wave events.<br />

The Western Indian Ocean Marine<br />

<strong>Applications</strong> Project aims to contribute<br />

to the sustainable management<br />

and optimum exploitation <strong>of</strong><br />

marine and land resources. This will<br />

be achieved through efficient planning<br />

using improved weather forecasts<br />

and climate and ocean predictions.<br />

It therefore focuses on building<br />

the capacity <strong>of</strong> national institutions in<br />

the relevant fields.<br />

An exceptional feature in this issue is<br />

an interview with Sir David King,<br />

Chief Scientific Adviser to the United<br />

Kingdom Government. Other important<br />

articles are “Making climate<br />

serve the people”, by M. Glantz,<br />

reviews <strong>of</strong> the global climate system<br />

and <strong>of</strong> global crop production in 2005<br />

and an analysis <strong>of</strong> a phenomenal rainfall<br />

event in Mumbai (India) in 2005.


Interview<br />

with<br />

Mr Francesco<br />

Frangialli<br />

Secretary-General <strong>of</strong> the United<br />

Nations World Tourism Organization<br />

(UNWTO)<br />

Tourism is one <strong>of</strong> the world’s<br />

largest economic sectors and it is<br />

developing rapidly. In some<br />

countries, it is the main source <strong>of</strong><br />

income. How do you see its<br />

future?<br />

The strong and sustained rise <strong>of</strong><br />

<strong>tourism</strong> over the past 50 years is one<br />

<strong>of</strong> the most remarkable phenomena<br />

<strong>of</strong> our time. Tourism has shown itself<br />

to be a strong contributor to the<br />

balance <strong>of</strong> payments, as well as a<br />

highly labour-intensive activity that<br />

opens up opportunities for the small<br />

businesses that provide it with products<br />

and services. Its impact is<br />

particularly strong in local farming,<br />

fishing and handicraft and even the<br />

construction industry. In developing<br />

countries, especially, <strong>tourism</strong> creates<br />

many direct and indirect jobs. It represents<br />

fertile ground for private<br />

initiative. It serves as a foothold for<br />

the development <strong>of</strong> a market economy<br />

where small and medium-sized<br />

enterprises can expand and flourish.<br />

In poor rural areas, it <strong>of</strong>ten constitutes<br />

the only alternative to subsistence<br />

farming, which is in decline.<br />

The number <strong>of</strong> international tourist<br />

arrivals has grown from 25 million in<br />

1950 to 808 million in 2005. This<br />

increase in physical flows is equivalent<br />

to an average annual growth <strong>of</strong> 7 per<br />

cent over a long period. The revenues<br />

generated by these arrivals—not<br />

including airline ticket sales and<br />

revenues from domestic <strong>tourism</strong>—<br />

have risen by 11 per cent a year<br />

(adjusted for inflation) over the same<br />

time-span. This rate <strong>of</strong> growth far<br />

outstrips that <strong>of</strong> the world economy as<br />

a whole. International <strong>tourism</strong> receipts<br />

reached US$ 622 billion in 2004,<br />

making it one <strong>of</strong> the largest categories<br />

<strong>of</strong> international trade. This trend is<br />

about to continue, despite a series <strong>of</strong><br />

natural disasters and terrorist threats.<br />

We expect international tourist arrivals<br />

to increase to 1.6 billion by 2020.<br />

How does weather impact <strong>tourism</strong><br />

and its sustainable development?<br />

What is the impact on decisions<br />

taken without the use <strong>of</strong> weather<br />

or climate information and <strong>of</strong><br />

using incorrect or uncertain<br />

information?<br />

For <strong>tourism</strong> businesses, accurate<br />

weather and climate information, as<br />

well as the prediction <strong>of</strong> extreme<br />

weather events, are becoming<br />

increasingly important, given that the<br />

programming <strong>of</strong> many <strong>tourism</strong> activities<br />

is heavily climate-dependent, and<br />

that insurance practices in <strong>tourism</strong> are<br />

greatly impacted by natural hazards.<br />

It is obvious that, if the planning and<br />

daily operation <strong>of</strong> <strong>tourism</strong> activities are<br />

carried out without adequate weather<br />

information, these can greatly affect<br />

the comfort, health and safety <strong>of</strong> holiday-makers,<br />

jeopardizing the overall<br />

tourist experience. It is especially true<br />

for beach, nature-<strong>tourism</strong> and other<br />

outdoor activities, where the timing <strong>of</strong><br />

programmes, the preparation <strong>of</strong><br />

proper equipment, clothing and other<br />

accessories, are highly weather- and<br />

climate-dependent.<br />

Regarding the longer-term sustainable<br />

development <strong>of</strong> <strong>tourism</strong>, I believe that<br />

climate factors and accurate climate<br />

information will be increasingly determinant.<br />

Tourism forms the backbone<br />

<strong>of</strong> the economy in many local communities<br />

worldwide. Adverse climatic<br />

conditions arising from climate<br />

change can seriously harm <strong>tourism</strong><br />

operations and the host communities<br />

that depend on them.<br />

Many destinations can be mentioned.<br />

For example, how would the residents<br />

<strong>of</strong> Zermatt in Switzerland make<br />

a living without sufficient snow covering<br />

its emblematic peak and the<br />

surrounding ski slopes; how would<br />

<strong>tourism</strong>-related businesses in<br />

Chamonix in France survive without<br />

excursions to its famous glacier “mer<br />

de glace” that has been retreating<br />

because <strong>of</strong> atmospheric warming; or<br />

the surfing industry at Waikiki Beach<br />

in Hawaii without large waves and<br />

sunny weather; the tropical paradise<br />

<strong>of</strong> the Maldives without safe diving<br />

because <strong>of</strong> frequent storms, reduced<br />

visibility and damaged reefs, or the<br />

golf courses on the Costa del Sol in<br />

Spain without the water to keep them<br />

green?<br />

Does the <strong>tourism</strong> sector feel it has<br />

enough information on weather<br />

and climate to plan and to serve<br />

clients’ interests? If not, what will<br />

it need from National Weather<br />

Services and <strong>WMO</strong> to help develop<br />

its activities in a sustainable<br />

manner?<br />

Weather patterns are shifting; climate<br />

variability and climate change will<br />

constitute an increasing risk for<br />

<strong>tourism</strong> operations in many destinations.<br />

Governments and the private<br />

sector should place importance on the<br />

management and use <strong>of</strong> climate information<br />

and incorporate climate factors<br />

in <strong>tourism</strong> policies, development and<br />

management plans. For this, effective<br />

coordination between environmental<br />

and <strong>tourism</strong> organizations is determinant<br />

for further research,<br />

awareness-raising and capacity-building,<br />

as well as the development and<br />

application <strong>of</strong> adaptation and mitigation<br />

measures in the <strong>tourism</strong> sector.<br />

We are still in the phase <strong>of</strong> raising<br />

awareness about weather- and<br />

climate-related information. An<br />

increasing number <strong>of</strong> severe natural<br />

disasters contribute to speeding up<br />

this process. I believe that the support<br />

<strong>of</strong> National Weather Services and <strong>of</strong><br />

<strong>WMO</strong> is crucial for this purpose. There<br />

is good evidence in the travel media,<br />

for example on Websites where<br />

climate aspects are incorporated as<br />

part <strong>of</strong> tourist information. It is hard,<br />

however, to estimate to what extent<br />

the <strong>tourism</strong> sector uses the information<br />

produced by National Weather<br />

Services and whether it is done in an<br />

effective manner. This is an interesting<br />

subject: perhaps <strong>WMO</strong> and UNWTO<br />

could engage in a joint survey and<br />

analysis. Guidelines could then be<br />

developed and good practices identified<br />

as to how public and private<br />

<strong>tourism</strong> organizations—and the<br />

tourists themselves—could better use<br />

climate information.<br />

In this context, WTO is currently<br />

preparing project proposals on climatechange<br />

adaptation in <strong>tourism</strong>, which<br />

will be submitted to the Global<br />

Environmental Facility. A series <strong>of</strong> pilot<br />

projects will assist selected Small<br />

Island Developing States (SIDS) in<br />

order to develop and demonstrate<br />

adaptation policies and techniques for<br />

beach destinations and coastal<br />

ecosystems. National committees will<br />

be formed and we expect that National<br />

Weather Services will be fully<br />

involved.<br />

How does the <strong>tourism</strong> sector use<br />

weather forecasts for short-term<br />

decision-making? Does it also use<br />

climate forecasts for mid-term<br />

decisions and climate change<br />

projections for long-term planning?<br />

Favourable climatic conditions are key<br />

attractions for holiday-makers. It is<br />

especially true for beach destinations<br />

and the conventional sun-and-sea<br />

segment, which is still the main form<br />

<strong>of</strong> <strong>tourism</strong>. Tourists are attracted to<br />

Mediterranean coasts and tropical<br />

islands by ample sunshine, warm<br />

temperatures and little precipitation, to<br />

escape the harsher seasons and<br />

weather conditions <strong>of</strong> their home<br />

countries. Mountain <strong>tourism</strong> and<br />

winter sports are also highly dependent<br />

on favourable climate and weather<br />

conditions, such as adequate precipitation<br />

and snow levels. In general,<br />

accurate climate and weather information<br />

is key for planning and carrying<br />

out trips and outdoor activities.<br />

In spite <strong>of</strong> the evident importance <strong>of</strong><br />

climate factors for the long-term viability<br />

<strong>of</strong> <strong>tourism</strong> businesses, climate<br />

information is used mostly for shortterm<br />

decision-making for <strong>tourism</strong><br />

operations and programming <strong>of</strong> activities<br />

through weather forecasts. The<br />

strategic importance <strong>of</strong> climate factors<br />

in <strong>tourism</strong> planning and development<br />

was emphasized at the first<br />

International Conference on Climate<br />

Change and Tourism, convened by<br />

UNWTO in Djerba, Tunisia, in 2003,<br />

with the collaboration <strong>of</strong> six UN agencies,<br />

including <strong>WMO</strong>. Nevertheless,<br />

the use <strong>of</strong> long-term climate-change<br />

projections is currently very limited in<br />

the <strong>tourism</strong> sector and there is much<br />

to be done in this field.<br />

A SIDS pilot country project is<br />

currently underway in Fiji, where a<br />

study revealed that various coastal<br />

resort areas are located in zones at risk<br />

from tropical cyclones. It is obvious<br />

that, when decisions were taken on<br />

designating some <strong>of</strong> these areas for<br />

resort development, climate information<br />

was not taken fully into<br />

consideration. The project aims to<br />

develop a climate-change adaptation<br />

strategy for <strong>tourism</strong> in Fiji as part <strong>of</strong> an<br />

overall risk-management framework<br />

with a long-term perspective. Mid- and<br />

long-term climate change projection<br />

and climate information will therefore<br />

be critical in this process.<br />

How does the sector cope with<br />

changes in seasonal climate<br />

patterns? Is projected climate<br />

change expected to affect <strong>tourism</strong>?<br />

Climatic conditions are dynamically<br />

changing, posing new risks to <strong>tourism</strong><br />

operations. The <strong>tourism</strong> sector needs<br />

to develop its capacity to adapt in<br />

order to maintain its viability, to<br />

continue generating socio-economic<br />

benefits for the host communities and<br />

to provide quality experiences for<br />

tourists.<br />

Climate—in the form <strong>of</strong> daily weather,<br />

extreme events, or gradual changes—<br />

impacts <strong>tourism</strong> both directly and<br />

indirectly. Directly, climate variability<br />

and changing weather patterns can<br />

affect the planning <strong>of</strong> <strong>tourism</strong><br />

programmes and daily operations.


Changing weather patterns at holiday<br />

destinations can significantly affect<br />

holiday-makers’ comfort, their decisions<br />

about making trips and, finally,<br />

the tourist flow. For example, a<br />

warmer summer in Europe can reduce<br />

the motivation <strong>of</strong> inhabitants <strong>of</strong> northern<br />

countries to visit the<br />

Mediterranean coasts that can be<br />

excessively hot in summertime; destinations<br />

closer to home can be more<br />

attractive. If the usual high season <strong>of</strong><br />

northern hemisphere summer months<br />

becomes too hot for tourists, a shift<br />

might occur towards taking holidays in<br />

cooler months, further inland or higher<br />

altitude areas that are cooler. Climate<br />

change can bring both problems and<br />

opportunities. The <strong>tourism</strong> sector<br />

needs to understand these trends in<br />

order to be prepared and adapt.<br />

Climate change can have a significant,<br />

indirect impact on <strong>tourism</strong> activities by<br />

altering the natural environment that<br />

represents both a key attraction and<br />

basic resource for <strong>tourism</strong>. Examples<br />

<strong>of</strong> negative impacts are coastal<br />

erosion, damage to coral reefs and<br />

other sensitive and biodiversity-rich<br />

ecosystems, or insufficient snow<br />

coverage at winter sports destinations.<br />

Problems with water supply<br />

affect a wide range <strong>of</strong> destinations,<br />

especially when it is considered that<br />

the high holiday season and increased<br />

demand for water coincides with dry<br />

periods and reduced water-supplies.<br />

A more personal observation will illustrate<br />

the overall point I wish to make.<br />

It so happens that, aside from my<br />

functions within the United Nations<br />

system, I am also the deputy mayor <strong>of</strong><br />

my village in the French Alps, Morzine-<br />

Avoriaz, a community <strong>of</strong> 3 000 people<br />

on the Swiss border, 90 km from<br />

Geneva. Morzine-Avoriaz is a village<br />

like any other, but for the fact that it is<br />

a popular destination for skiing and<br />

other winter sports. It has an accommodation<br />

capacity <strong>of</strong> 37 000 beds, half<br />

in the valley at an altitude <strong>of</strong> 1 000 m<br />

and the other half in a new resort at<br />

1 800 m.<br />

As seen from my village, climate<br />

change is not a potential problem but a<br />

reality that is being experienced now.<br />

Nowadays, the lower limit <strong>of</strong> the snow<br />

cover on the southern slopes, depending<br />

on the year, is 200-300 m higher<br />

than it was 50 years ago. In the 1970s,<br />

at an altitude <strong>of</strong> 1 800 m, we used to<br />

receive 13-14 m <strong>of</strong> cumulative snowfall<br />

during the winter. Today, we<br />

receive half that: 6-7 m. Our main<br />

concern stems not so much from<br />

warming itself, but rather low precipitation<br />

in winter. In the neighbouring<br />

Chamonix Valley, the glaciers <strong>of</strong> the<br />

Mont Blanc massif—a major <strong>tourism</strong><br />

attraction—have retreated some<br />

500 m, i.e. they are back to their levels<br />

<strong>of</strong> the 1960s, before their advance <strong>of</strong><br />

the 1970s until 1983.<br />

In this part <strong>of</strong> the northern Alps, the ski<br />

industry is now concentrated at highaltitude<br />

resorts. It has survived, thanks<br />

to better ski-run grooming and the<br />

introduction <strong>of</strong> snow cannons, but the<br />

latter is only a palliative measure that<br />

itself creates other environmental<br />

problems regarding water consumption<br />

and visual and noise pollution.<br />

We are worried about the future. A<br />

study by the French Meteorological<br />

Service (Météo-France) tells us that<br />

the duration <strong>of</strong> snow cover, which is<br />

currently <strong>of</strong> the order <strong>of</strong> five months at<br />

1 500 m, could be reduced by 40 days<br />

if temperatures rise just 1.8°C. For us,<br />

that would mean no more snow for<br />

the year-end holidays or the spring<br />

break. Conservative estimates <strong>of</strong><br />

warming in our region for the present<br />

century are well above 1.8°C.<br />

We are trying to respond by diversifying<br />

our <strong>tourism</strong> products, with<br />

increased reliance on the summer<br />

season and the <strong>of</strong>f-season. We are<br />

Francesco Frangialli with K<strong>of</strong>i Annan,<br />

Secretary-General <strong>of</strong> the United Nations<br />

making an effort to promote <strong>tourism</strong><br />

that is more sustainable and to<br />

address mobility problems regarding<br />

access to the village through an urban<br />

<strong>transport</strong> plan and the introduction <strong>of</strong><br />

electrically powered shuttles within<br />

the village. We are taking care to<br />

preserve the character <strong>of</strong> Avoriaz as a<br />

car-free, high-altitude resort. We want<br />

to reduce our contribution to greenhouse-gas<br />

emissions. We are well<br />

aware that we will not solve the<br />

planet’s problems at the level <strong>of</strong> our<br />

community, but if those who have the<br />

means do not do so, who will?<br />

Is the frequency <strong>of</strong> natural disasters<br />

a major factor? How important<br />

is weather and climate information<br />

among these factors?<br />

Extreme weather events, such as<br />

cyclones, hurricanes and flooding,<br />

can damage <strong>tourism</strong> infrastructure<br />

physically and pose a great risk for<br />

the safety <strong>of</strong> both holiday-makers and<br />

host communities. Moreover, tourist<br />

destinations affected by major<br />

weather-related hazards can suffer<br />

greatly from secondary effects, such<br />

as economic impacts on local businesses<br />

or a negative image in the<br />

media. In the aftermath <strong>of</strong> these<br />

73


74<br />

tragic events, it takes much effort to<br />

rebuild both the physical environment<br />

and the image <strong>of</strong> destinations. The<br />

hurricanes that swept through the<br />

Caribbean in 2005 reinforced the<br />

prediction that, in the long term, both<br />

the frequency and strength <strong>of</strong><br />

cyclones would increase. Early warning<br />

systems and weather-information<br />

services are vital to prevent major<br />

hazards at <strong>tourism</strong> destinations<br />

becoming disasters.<br />

Does the sector have contingency<br />

plans for climate-related and manmade<br />

emergencies?<br />

In 1998, UNWTO, jointly with <strong>WMO</strong>,<br />

published the Handbook on Natural<br />

Disaster Reduction in Tourist Areas.<br />

A significant part <strong>of</strong> this publication<br />

addresses contingency planning and<br />

preparedness for extreme events.<br />

Unfortunately, emergency situations<br />

caused by natural phenomena and<br />

man-made events are not new to the<br />

<strong>tourism</strong> sector, which endured a<br />

number <strong>of</strong> crisis situations in the<br />

past. The event <strong>of</strong> 11 September<br />

2001 and the various crises <strong>of</strong> these<br />

past few years, such as severe acute<br />

respiratory syndrome (SARS)<br />

disease, the Indian Ocean tsunami,<br />

oil price rises and other socioeconomic<br />

uncertainties, dealt a<br />

severe blow to the sector globally. It<br />

has always shown strong resilience,<br />

however, and is already back on the<br />

path <strong>of</strong> strong growth. UNWTO has<br />

been addressing crisis-management<br />

issues through research, producing<br />

guidelines and providing capacitybuilding<br />

and technical assistance to<br />

its members in the field. We also aim<br />

to avert crisis situations by improving<br />

information services and collaborating<br />

with other institutions,<br />

such as with the World Health<br />

Organization on the current avian<br />

influenza issue.<br />

How can WTO and <strong>WMO</strong> work<br />

together to strengthen their<br />

already solid relationship and<br />

enhance national and regional<br />

collaboration? Can joint activities<br />

include biometeorological studies<br />

in support <strong>of</strong> the Olympics, for<br />

example?<br />

There has been good collaboration<br />

between the two UN specialized agencies,<br />

based on the <strong>of</strong>ficial cooperation<br />

agreement signed in 1992. Among<br />

recent activities, I would like to highlight<br />

the discussions held at the UN<br />

Coordination Meeting on Tourism<br />

Matters, organized by UNWTO in 2004<br />

and UNWTO’s contribution to the<br />

recent edition <strong>of</strong> <strong>WMO</strong>’s World<br />

Climate News, that was dedicated to<br />

climate and <strong>tourism</strong> issues. I also had<br />

the opportunity to participate in the<br />

<strong>WMO</strong> Technical Conference on<br />

Climate as a Resource that preceded<br />

the 14th session <strong>of</strong> the <strong>WMO</strong><br />

Commission for Climatology (Beijing,<br />

November 2005). We warmly support<br />

the decision adopted by the<br />

Commission to formulate an Expert<br />

Team on Climate and Tourism and fully<br />

agree with the terms <strong>of</strong> reference.<br />

These activities can be the basis for an<br />

excellent agenda for collaboration.<br />

Among these, the strengthening <strong>of</strong><br />

working relationships between<br />

National Tourism Administrations and<br />

National Weather Services should be a<br />

priority.<br />

There are intensive research activities<br />

in bio<strong>meteorology</strong> and a growing body<br />

<strong>of</strong> knowledge that can be applied, for<br />

example, to the comfort, health and<br />

safety <strong>of</strong> tourists, and tourists’ perception<br />

<strong>of</strong> climate factors; these<br />

conditions are determinant for a<br />

satisfying vacation experience.<br />

UNWTO has been involved in sports<br />

<strong>tourism</strong> and has organized international<br />

events, also with a special focus<br />

on winter sports. Biometeorological<br />

studies in support <strong>of</strong> sport <strong>tourism</strong><br />

Francesco Friangialli participated in the<br />

<strong>WMO</strong> Technical Conference on Climate as a<br />

Resource in Beijing, China, in November<br />

2005. He is pictured here (front row, second<br />

from left) with (to his left) the Secretary-<br />

General <strong>of</strong> <strong>WMO</strong>, Michel Jarraud, and the<br />

Permanent Representative <strong>of</strong> China with<br />

<strong>WMO</strong>, Qin Dahe.<br />

activities and major sport events, such<br />

as the Olympics, could certainly be<br />

another potential field <strong>of</strong> cooperation<br />

between our agencies.<br />

How important is the environment,<br />

compared to pr<strong>of</strong>itability, in<br />

managing <strong>tourism</strong>? Are there any<br />

social, economic, legislative or<br />

political hurdles that hamper (or<br />

discourage) integration <strong>of</strong> climate<br />

and environment into planning?<br />

Natural environment and environmental<br />

resources form the sole basis <strong>of</strong><br />

any <strong>tourism</strong> products and activities;<br />

they should not be jeopardized by<br />

short-term objectives <strong>of</strong> economic<br />

exploitation and pr<strong>of</strong>it-making.<br />

UNWTO has been promoting a<br />

sustainable development approach in<br />

the <strong>tourism</strong> sector, emphasizing the<br />

need for a balance in the environmental,<br />

economic and socio-cultural<br />

aspects. We have produced a series <strong>of</strong><br />

guidelines and manuals, and organized<br />

numerous capacity-building events


and conferences in order to support<br />

members <strong>of</strong> the public and private<br />

sectors in formulating and implementing<br />

sustainable <strong>tourism</strong> policies,<br />

strategies and plans. Sustainable<br />

<strong>tourism</strong> is also a main driver <strong>of</strong> our<br />

technical cooperation activities,<br />

whereby we provide assistance to<br />

countries to formulate master plans<br />

and sectoral strategies.<br />

There have been great advances in the<br />

<strong>tourism</strong> sector since the Rio Earth<br />

Summit (1992) and there are various<br />

international processes and events<br />

that underpin these. Among these<br />

may be mentioned the UN<br />

Commission on Sustainable Development<br />

that dedicated its seventh<br />

session entirely to <strong>tourism</strong> issues in<br />

1999; the International Year <strong>of</strong><br />

Eco<strong>tourism</strong> in 2002; and the inclusion<br />

<strong>of</strong> <strong>tourism</strong> in the Plan <strong>of</strong> Action <strong>of</strong> the<br />

World Summit on Sustainable<br />

Development (Johannesburg, 2002).<br />

There is also a growing number <strong>of</strong><br />

private-sector-led programmes, for<br />

example, the Tour Operators Initiative,<br />

which comprises some 20 leading tour<br />

operators, who joined forces to foster<br />

the application <strong>of</strong> sustainable practices<br />

along the <strong>tourism</strong> supply chain and at<br />

<strong>tourism</strong> destinations.<br />

A policy report on sustainable <strong>tourism</strong>,<br />

prepared for the Johannesburg<br />

Summit by UNWTO, concluded that<br />

there have been great advances in<br />

creating awareness <strong>of</strong> sustainability<br />

issues in the <strong>tourism</strong> sector. Many<br />

countries declare they are pursuing, or<br />

wish to pursue, policies for “sustainable<br />

<strong>tourism</strong>”. Nevertheless, a degree<br />

<strong>of</strong> uncertainty remains over the possibilities<br />

and priorities for making<br />

<strong>tourism</strong> more sustainable and only a<br />

partial appreciation <strong>of</strong> how to put this<br />

into practice. Today, a wide range <strong>of</strong><br />

technical and technological solutions is<br />

available for minimizing <strong>tourism</strong>’s<br />

negative impacts and maximizing its<br />

social and economic benefits. Yet, the<br />

application <strong>of</strong> these solutions has been<br />

relatively slow and partial in most<br />

destinations. The practical application<br />

<strong>of</strong> <strong>tourism</strong> planning and management<br />

techniques and the effective implementation<br />

<strong>of</strong> <strong>tourism</strong> policies and<br />

development plans are the greatest<br />

challenges the <strong>tourism</strong> sector faces<br />

today.<br />

What are the highlights <strong>of</strong> the<br />

long-term strategy <strong>of</strong> WTO and<br />

how do you see the role <strong>of</strong><br />

weather and climate information in<br />

this context?<br />

Regarding the role <strong>of</strong> weather and<br />

climate information, our strategic<br />

objective is to assist destinations in<br />

preparing for, and adapting to, the<br />

long-term impacts <strong>of</strong> climate change,<br />

through conserving and enhancing the<br />

resilience <strong>of</strong> ecosystems, developing<br />

adequate <strong>tourism</strong> infrastructure and<br />

products and improving the management<br />

<strong>of</strong> climate information.<br />

Based on the results <strong>of</strong> the proposed<br />

pilot projects at island destinations, we<br />

plan to develop <strong>tourism</strong>-sector specific<br />

guidelines, and mainstream their application<br />

in other countries. We would<br />

like to extend studies and pilot projects<br />

to other types <strong>of</strong> destination as<br />

well, such as mountain regions. The<br />

initial focus was on island destinations<br />

as they are the most vulnerable to<br />

potential climate-change impacts,<br />

which are visible and felt in many <strong>of</strong><br />

them, such as extreme climatic<br />

events, rising sea-levels and freshwa-<br />

ter supply. This is also in line with our<br />

strategic objective <strong>of</strong> assisting Small<br />

Island Developing States, which we<br />

re-confirmed at the SIDS Global<br />

Summit in Mauritius in 2005.<br />

UNWTO is also collaborating in the<br />

process <strong>of</strong> preparing the Fourth<br />

Assessment Report coordinated by<br />

the Intergovernmental Panel on<br />

Climate Change. We have nominated<br />

experts in climate change and <strong>tourism</strong><br />

issues, and we are participating in the<br />

review process. I am pleased to see<br />

that <strong>tourism</strong> is more explicitly<br />

addressed in the Fourth Assessment<br />

Report than in previous ones, notably<br />

in Working Group II and its Chapter 7<br />

regarding industry, settlement and<br />

ssociety, as well as in some <strong>of</strong> the<br />

regional chapters. As climate scenarios<br />

and climate change prediction<br />

models are becoming more refined<br />

and more accurate at regional and local<br />

levels, we hope they can be increasingly<br />

applied at holiday destinations.<br />

We should not forget that there is a<br />

two-way relationship between<br />

<strong>tourism</strong> and climate, as was clearly<br />

stated in the Declaration issued at the<br />

Djerba Conference. Tourism is<br />

impacted by climate change, but also<br />

contributes to the causes <strong>of</strong> climate<br />

change, mainly through emissions<br />

from <strong>transport</strong>ation and consumption<br />

<strong>of</strong> energy in <strong>tourism</strong> facilities, as well<br />

as by altering the natural environment.<br />

We have been addressing these<br />

issues through promoting environmental<br />

practices as integrated parts <strong>of</strong><br />

destination management and <strong>tourism</strong><br />

operations.<br />

In all these processes we will count<br />

strongly on our collaboration with<br />

<strong>WMO</strong>. <br />

Interview with<br />

Sir David King<br />

Chief Scientific Adviser to<br />

HM Government <strong>of</strong> the<br />

United Kingdom<br />

Over the past few decades, global<br />

scientific and technical coordination<br />

and cooperation have led to<br />

better understanding <strong>of</strong> hazards<br />

and their impacts and availability <strong>of</strong><br />

operational warning capabilities.<br />

How critical is the role <strong>of</strong> the scientific<br />

and technical community in<br />

advancing disaster risk reduction<br />

and what more can be done?<br />

The scientific and technical community<br />

has a very important role to play<br />

in all phases <strong>of</strong> disaster risk reduction<br />

from mitigation to preparedness and<br />

response and recovery. It can help<br />

with the vulnerability assessment and<br />

identifying steps that should be taken<br />

to minimize the risks; for example<br />

identifying land that is prone to flooding<br />

or that could be affected by an<br />

earthquake or a volcano, or in the<br />

identification <strong>of</strong> evacuation procedures<br />

which will minimize risk.<br />

Scientists can help educate citizens<br />

about the nature <strong>of</strong> the hazards they<br />

face and how to recognize and<br />

respond safely to them. As was made<br />

clear in the tsunami <strong>of</strong> 26 December<br />

2004, it was the local knowledge <strong>of</strong> a<br />

handful <strong>of</strong> children and adults, which<br />

they had picked up at school or heard<br />

through generations <strong>of</strong> stories, which<br />

saved lives. For response and recovery,<br />

ongoing warnings <strong>of</strong> how the<br />

event is developing and what other<br />

types <strong>of</strong> factors may affect the<br />

response are essential.<br />

There is a lot more that the scientific<br />

community can do besides the ongoing<br />

need for research to increase<br />

our knowledge and understanding <strong>of</strong><br />

potentially hazardous events. Better<br />

integration and collaboration between<br />

different scientific disciplines to<br />

improve understanding <strong>of</strong> impacts<br />

and the links between different types<br />

<strong>of</strong> hazards is an area which needs<br />

development, such as the effects <strong>of</strong><br />

weather situations on the spread <strong>of</strong><br />

infectious disease.<br />

There needs to be improvements in<br />

the monitoring <strong>of</strong> potentially hazardous<br />

events such as volcanoes,<br />

weather, climate change and the<br />

spread <strong>of</strong> infectious diseases.<br />

As well as ongoing development and<br />

improvements to operational early<br />

warning systems and services, more<br />

expert peer review <strong>of</strong> scientific<br />

knowledge and understanding is<br />

required to provide a “consensus”<br />

view on hazards and to determine<br />

when the state <strong>of</strong> the science is<br />

ready to develop a useful warning<br />

capability.<br />

In the report to the United<br />

Kingdom Government entitled The<br />

Role <strong>of</strong> Science in Physical Natural<br />

Hazard Assessment by the Natural<br />

Hazard Working Group, which you<br />

commissioned, the establishment<br />

<strong>of</strong> an International Science Panel<br />

for Natural Hazard Assessment<br />

was recommended. In your<br />

opinion, how can such a panel<br />

influence national disaster risk<br />

management policies most<br />

effectively?<br />

An International Science Panel can<br />

provide a worldwide authoritative scientific<br />

view <strong>of</strong> potential global- or<br />

regional-scale hazards, e.g. potential<br />

for earthquakes in different regions. It<br />

would cross disciplines and involve<br />

many international scientists, to pool<br />

knowledge and expertise.<br />

I would envisage that it would be able<br />

to provide an expert peer review <strong>of</strong><br />

scientific knowledge <strong>of</strong> different types<br />

<strong>of</strong> hazard, leading to recommendations<br />

for particular areas <strong>of</strong> research<br />

and recommendations regarding how<br />

to utilize scientific knowledge to<br />

improve different phases <strong>of</strong> disasterrisk<br />

reduction (e.g. planning or development<br />

or improvement <strong>of</strong> warning<br />

systems).<br />

The same report strongly<br />

supported the need for early<br />

warning systems for all hazards.<br />

How would you assess progress to<br />

date and the benefits <strong>of</strong> the multihazard<br />

early warning system<br />

approach?<br />

I was pleased that the report was<br />

welcomed by many parties following its<br />

publication last June. The multi-hazard<br />

warning system has since been internationally<br />

endorsed with the G8 leaders,<br />

the United Nations and the international<br />

Group on Earth Observations all recognizing<br />

the need for such an approach.


I know the United Nations is developing<br />

the idea for a science panel which<br />

I have been consulted on and I am<br />

looking forward to seeing how this is<br />

integrated into the overall system.<br />

There are many elements <strong>of</strong> an early<br />

warning system which are independent<br />

<strong>of</strong> the type <strong>of</strong> hazard, for example<br />

the need to ensure appropriate links<br />

between relevant authorities and decision-makers<br />

and the need to have<br />

appropriate mechanisms in place to<br />

communicate warnings to the public<br />

and to increase their awareness <strong>of</strong><br />

hazards. Different types <strong>of</strong> hazards<br />

<strong>of</strong>ten interact, e.g. a tropical cyclone<br />

causing a storm surge, or a flood leading<br />

to outbreak <strong>of</strong> disease. I have met<br />

Michel Jarraud several times now and<br />

know that <strong>WMO</strong> is continuing to<br />

develop its system for all hazards to<br />

include non-hydrometeorological hazards,<br />

such as emergencies arising<br />

from nuclear accidents, volcanic eruptions,<br />

airborne disease, forest and<br />

wildland fires and chemical accidents.<br />

I am sure he will keep up the momentum<br />

that we have started.<br />

There has also been progress in<br />

developing the tsunami early warning<br />

systems in the Indian Ocean and<br />

other regions which is good news,<br />

considering the Asian tsunami was<br />

what prompted the Prime Minister <strong>of</strong><br />

Sir David was guest<br />

<strong>of</strong> honour at the<br />

World<br />

Meteorological Day<br />

2006 celebrations at<br />

<strong>WMO</strong> Headquarters.<br />

His presentation<br />

entitled “From<br />

science to action” is<br />

available on the<br />

World<br />

Meteorological Day<br />

Website:<br />

http://www.wmo.int/<br />

wmd/<br />

the United Kingdom to set up the<br />

Working Group.<br />

While there has been significant<br />

progress in the technical aspects <strong>of</strong><br />

hazard and risk analysis and early<br />

warnings, many challenges remain<br />

related to legislative, legal and<br />

organizational capacities and<br />

linkages. How can we overcome<br />

these challenges? What needs to<br />

be done at international and<br />

national levels?<br />

The main challenge is ensuring that<br />

hazard and risk analysis and early<br />

warning systems are integrated into<br />

an overall disaster-risk reduction plan.<br />

Warning systems have to be integrated<br />

into people’s lives to make<br />

them accessible and easy to understand,<br />

and so does disaster risk reduction<br />

in the broader sense.<br />

Globally, there needs to be an<br />

exchange <strong>of</strong> information by developing<br />

universal data formats, dataexchange<br />

agreements and agreeing<br />

global roles for organizations with the<br />

most developed capabilities.<br />

Encouraging global and regional cooperation<br />

and coordinating approaches<br />

between development agencies and<br />

organizations is crucial for any early<br />

warning system to work. Regional<br />

cooperation needs to exist to ensure<br />

that regional developments tree up to,<br />

and support, coordinated global activities<br />

and that the global activities feed<br />

in to regional approaches.<br />

Traditionally, activities in natural<br />

disaster risk reduction have<br />

focused on post-disaster<br />

emergency recovery and<br />

humanitarian response, both at<br />

national level and within the<br />

international donor community.<br />

How can science influence a shift<br />

to a culture <strong>of</strong> prevention<br />

effectively?<br />

We need to improve awareness <strong>of</strong><br />

the impacts <strong>of</strong> disasters, including the<br />

links between different hazards, and<br />

the socio-economic benefits <strong>of</strong> investing<br />

in disaster-risk reduction. The<br />

World Bank has determined that<br />

every dollar spent in preparing for a<br />

natural disaster saves seven in<br />

response.<br />

At the World Conference on Disaster<br />

Reduction (Kobe, Japan, January<br />

2005), there was a call for commitment<br />

from donors to increase the percentage<br />

<strong>of</strong> their funds allocated to disaster<br />

prevention, and a statement<br />

was made by the United Kingdom<br />

International Development Minister<br />

supporting this and committing the<br />

United Kingdom to this aim.<br />

We must not forget that scientists<br />

can provide the education in order to<br />

raise awareness <strong>of</strong> the potential capabilities<br />

to warn <strong>of</strong> impending hazardous<br />

situations, and how to use scientific<br />

information and products for<br />

maximum benefit.<br />

Recent scientific and technical<br />

developments related to observing<br />

networks, data-processing,<br />

77


78<br />

forecasting and telecommunications,<br />

among others, have<br />

helped minimize the impacts <strong>of</strong><br />

disasters. However, development,<br />

maintenance and durability <strong>of</strong><br />

these capacities require long-term<br />

resource commitments at national<br />

and international levels. In a world<br />

<strong>of</strong> competing interests, what<br />

mechanisms can be used to ensure<br />

these capacities remain a longterm<br />

priority?<br />

We have only to look back at the past<br />

18 months to see what total destruction<br />

and devastation can occur from<br />

natural disasters. These events<br />

remind us <strong>of</strong> what we should be<br />

doing to minimize the effects <strong>of</strong> these<br />

hazards. In the first instance, the relevant<br />

national scientific and technical<br />

organizations such as National Meteorological<br />

and Hydrological Services<br />

(NMHSs) need to work with their own<br />

governments to make them aware <strong>of</strong><br />

the benefits <strong>of</strong> investing in such<br />

mechanisms and capabilities, both in<br />

terms <strong>of</strong> disaster-risk reduction as<br />

well as on a day-to-day basis for other<br />

types <strong>of</strong> services and uses. The benefits<br />

<strong>of</strong> investing in such mechanisms<br />

and capabilities need to be clearly<br />

shown to donor agencies and organizations,<br />

to encourage them to support<br />

such activities.<br />

We need to encourage global,<br />

regional and national cooperation to<br />

optimize such infrastructure and<br />

capabilities and share resources and<br />

capabilities.<br />

National Meteorological and Hydrological<br />

Services contribute significantly<br />

to disaster-risk reduction<br />

through the issue <strong>of</strong> comprehensive<br />

information about hazards and<br />

early warnings. However, the role<br />

<strong>of</strong> these Services is not always fully<br />

recognized at the political level,<br />

while their resources and capabili-<br />

by Sergei Ordzhonikidze, Director-General, United Nations Office at Geneva (left), on the<br />

occasion <strong>of</strong> World Meteorological Day 2006. Sir David is pictured here (second from right)<br />

with the artist (second from left) and Mr Michel Jarraud, Secretary-General, <strong>WMO</strong>.<br />

ties vary significantly from country<br />

to country. How can we optimize<br />

their contribution to disaster risk<br />

reduction?<br />

National Meteorological and Hydrological<br />

Services must provide the best<br />

possible information, forecasts and<br />

warnings. For those NMHSs with<br />

less-developed capabilities, they could<br />

utilize the capabilities <strong>of</strong> another<br />

NMHS, either within the global system<br />

or within the same region.<br />

More generally, these Services could<br />

improve their visibility both with the<br />

public via TV presentations and with<br />

relevant government and local authorities,<br />

including linking with disastermanagement<br />

agencies or national disaster<br />

platforms. This would ensure<br />

that their capabilities and potential<br />

involvement in the national or community<br />

disaster plans is understood and<br />

is utilized to the best effect.<br />

In what ways do you consider<br />

<strong>WMO</strong> could further its contributions<br />

to disaster risk reduction?<br />

As I said earlier, I am pleased <strong>WMO</strong><br />

is continuing to take forward the<br />

disaster-risk reduction agenda,<br />

particularly developing its system to<br />

include non-hydrometeorological<br />

warning systems. However, there is<br />

always more we can be doing. I think<br />

there is room for <strong>WMO</strong> to cooperate<br />

even more closely with other United<br />

Nations agencies and international<br />

organizations in order to develop multiagency<br />

collaboration. This would<br />

improve knowledge, develop<br />

operational capabilities and raise<br />

awareness <strong>of</strong> hazards and their<br />

impacts in the most efficient and<br />

effective way.<br />

Other areas where <strong>WMO</strong> could contribute<br />

further could be encouraging<br />

multi-disciplinary collaboration on<br />

research and development. It could<br />

continue to raise awareness <strong>of</strong> the<br />

capabilities <strong>of</strong> the global network <strong>of</strong><br />

NMHSs, and further encourage these<br />

to work together to make optimum<br />

use <strong>of</strong> these collective capabilities.<br />

Further training and education <strong>of</strong> less<br />

developed Services would also be<br />

very useful.


<strong>Applications</strong><br />

<strong>of</strong><br />

<strong>meteorology</strong><br />

for <strong>tourism</strong><br />

in Mauritius<br />

By Mohamudally Beebeejaun*<br />

Introduction<br />

Mauritius consists <strong>of</strong> a main island<br />

and a group <strong>of</strong> small islands scattered<br />

in the south-west Indian Ocean,<br />

namely: Rodrigues, Agalega,<br />

Tromelin, the Cargados Caragos (St<br />

Brandon) and the Chagos Archipelago<br />

(Diego Garcia). The total land area <strong>of</strong><br />

Mauritius is 2 040 km 2 with an exclusive<br />

oceanic economic zone <strong>of</strong> 2 mil-<br />

lion km 2 . It was formed by the<br />

episodic eruption <strong>of</strong> basaltic lava<br />

some 8 million, 2 million and<br />

2 000 years ago. The coastline length<br />

<strong>of</strong> the main island, Mauritius, is<br />

322 km and is almost surrounded by<br />

fringing coral reefs except at two<br />

places in the south and west, where<br />

waves from the open sea crash<br />

directly against the shores. The<br />

lagoon area is about 243 km 2 .<br />

Rodrigues, with a lagoon area <strong>of</strong><br />

about 200 km 2 , is totally surrounded<br />

by a complex reef, except for passes.<br />

The coral reef <strong>of</strong> Saint Brandon and<br />

Agalega covers 190 km 2 and 100 km 2<br />

respectively.<br />

Mauritius lies on the edge <strong>of</strong> the<br />

southern tropical belt and is virtually<br />

free from influences <strong>of</strong> the continental<br />

airmass. It enjoys a mild maritime tropical<br />

climate with a warm and moist<br />

summer (November to April) and relatively<br />

cold winter (May to October).<br />

May and October are considered transition<br />

months with mainly dry and<br />

beautiful sunny days. It is generally<br />

swept by trade winds throughout the<br />

year, except for some short periods in<br />

summer season, when tropical storms<br />

approach the country.<br />

After independence in 1968, the Mauritian<br />

economy was based principally<br />

on agriculture. The economy has<br />

undergone several distinct development<br />

phases and, in the process, successfully<br />

diversified from a mono-crop<br />

economy, mostly dependent on the<br />

export <strong>of</strong> sugar, which is climatedependent,<br />

into manufacturing,<br />

<strong>tourism</strong>, exports, services and, more<br />

recently, to information technology<br />

and as a seafood hub and freeport.<br />

The <strong>tourism</strong> industry is projected to<br />

be the main pillar <strong>of</strong> the Mauritian<br />

economy in the years to come.<br />

Tourism<br />

* Mauritius Meteorological Services Hotels and bungalows along the white, sandy Mauritian beaches<br />

Tourism in Mauritius is not viewed as<br />

a single industry but a multiple one.<br />

Its impact is manifold and its current<br />

evolution depends on the economic,<br />

regional, local, social and cultural policies<br />

<strong>of</strong> the country. The <strong>tourism</strong> sector,<br />

which is mainly coastal-based, has<br />

gradually emerged as the second pillar<br />

79


80<br />

<strong>of</strong> the Mauritius economy and the<br />

hotels and restaurants were contributing<br />

some 7.6 per cent to the gross<br />

domestic product (GSDP) as at<br />

December 2005. Most <strong>of</strong> the tourist<br />

hotels are beach hotels/resorts within<br />

100 m <strong>of</strong> the high-water mark. Sun,<br />

sand and sea are the prime motivation<br />

<strong>of</strong> tourists coming to Mauritius in<br />

order to skip the cold and unsettled<br />

weather <strong>of</strong> their home countries. The<br />

number <strong>of</strong> tourist arrivals reached<br />

761 063 in the year 2005.<br />

The industry creates direct and indirect<br />

employment and is the only<br />

apparent stable economy in constant<br />

growth since the last 30 years. Unsustainable<br />

development <strong>of</strong> the <strong>tourism</strong><br />

industry, however, may aggress the<br />

marine environment or, conversely, a<br />

degraded coastal area may hinder the<br />

growth <strong>of</strong> <strong>tourism</strong>.<br />

Mauritius had to come up with new<br />

ideas in an attempt to protect both<br />

the coastal areas and the <strong>tourism</strong><br />

industry. In 2002, the Government<br />

created the Tourism Authority, which<br />

is responsible for providing licenses to<br />

organizations operating in the <strong>tourism</strong><br />

sector. The hotels, bungalows, guest<br />

houses, restaurants, airline agencies,<br />

guides, skippers, divers and beach<br />

hawkers have to abide by the norms<br />

set out by this <strong>of</strong>ficial authority. These<br />

operating agencies require meteorological<br />

outputs either to save energy,<br />

a valuable commodity, or reduce accidents<br />

during outdoor marine activities.<br />

To reduce pressure in the coastal<br />

zone, the Ministry <strong>of</strong> Tourism is<br />

encouraging the development <strong>of</strong><br />

eco<strong>tourism</strong>. The island has a number<br />

<strong>of</strong> sites <strong>of</strong> great ecological value such<br />

as the Black River Gorges, botanical<br />

gardens, islets and natural parks.<br />

These could be further exploited as<br />

they <strong>of</strong>fer environmentally sustainable<br />

opportunities for eco<strong>tourism</strong> developments.<br />

A total <strong>of</strong> 42 licensed<br />

Early warnings contribute to the safety <strong>of</strong> tourists against natural hazards.<br />

operators are already functioning in<br />

this sector. Nowcasting services<br />

provided by the Mauritius<br />

Meteorological Services, especially<br />

for local, short-lived thunderstorms,<br />

are extensively used during excursions<br />

to these sites. Moreover, the<br />

demand for such services is expected<br />

to increase sharply due to the fast<br />

expansion <strong>of</strong> these activities.<br />

Coastal zone<br />

Being small, the whole island <strong>of</strong> Mauritius<br />

may be considered a coastal<br />

zone but, as per the Environment Protection<br />

Act 2002, the coastal zone <strong>of</strong><br />

Mauritius is defined as any area that<br />

is situated within 1 km from the highwater<br />

mark, extending either side<br />

into the sea or inland. The island is<br />

endowed with sandy beaches, protected<br />

bays and calm lagoons, factors<br />

that have permitted the development<br />

<strong>of</strong> both <strong>tourism</strong> and fishing. The<br />

marine and coastal environment contributes<br />

significantly to the island’s<br />

economy through the rational<br />

exploitation <strong>of</strong> its living resources. It<br />

also attracts human settlement, hotel<br />

development and <strong>tourism</strong>.<br />

Over the past years, the coastal<br />

areas <strong>of</strong> Mauritius have experienced<br />

rapid development and have been<br />

extensively used for various activities.<br />

Coral sand removal (at the rate<br />

<strong>of</strong> 800 000 tonnes per year on average)<br />

and sewage discharge into<br />

lagoons has been allowed, with the<br />

result that some beaches and<br />

lagoons are now severely degraded.<br />

Furthermore, absence <strong>of</strong> proper<br />

planning and inadequate enforcement<br />

resulted in uncontrolled constructions<br />

on the coast and rapid<br />

deterioration <strong>of</strong> coastal resources.<br />

The coastal zone is constantly coming<br />

under severe stress; without<br />

immediate and appropriate action, its<br />

future looks quite bleak. An integrated<br />

strategy is being developed<br />

through the Integrated Coastal Zone<br />

Management Plan to mitigate its<br />

impacts.


The coastal zone represents the most<br />

valuable socio-economic assets <strong>of</strong><br />

Mauritius and the main source <strong>of</strong><br />

recreation and leisure to the locals. It<br />

is vulnerable to natural disasters, such<br />

as sea-level rise, tropical cyclones,<br />

climate variability, beach erosion and,<br />

more recently, tsunami.<br />

Impacts <strong>of</strong> adverse climate<br />

conditions on the coastal<br />

region <strong>of</strong> Mauritius<br />

The southern hemisphere winter<br />

months are characterized by the influence<br />

<strong>of</strong> the semi-permanent anticyclone<br />

and exhibits a rather strong<br />

south-east trade wind regime with<br />

gusts peaking over 100 km/h at times.<br />

When coupled with swell waves, generated<br />

along the Roaring Forties, large<br />

wave conditions may occur, affecting<br />

mainly the southern and western<br />

coasts.<br />

Tropical cyclones generally develop<br />

along the inter-tropical convergence<br />

zone and recurve towards the south.<br />

An average <strong>of</strong> 10 <strong>of</strong> these tropical systems<br />

occurs annually in the South-<br />

West Indian Ocean. Significant degradation<br />

<strong>of</strong> the coastal land and shoreline<br />

are caused through its associated<br />

phenomenal waves, strong winds,<br />

storm surges and torrential rain.<br />

Climate change, temperature rise and<br />

sea-level rise are yet other potential<br />

threats to the coasts: sea-level is rising<br />

at about 0.7 mm per year; air temperature<br />

has increased about 0.50°C<br />

during the last decade and precipitation<br />

patterns are changing.<br />

Small Island Developing States are<br />

highly vulnerable to climate change<br />

and ensuing sea-level rise. In Mauritius,<br />

the key socio-economic sectors<br />

which, are most likely to be affected,<br />

are coastal resources, water<br />

resources, health and well-being<br />

among others. The potential impacts<br />

on the coastal marine systems are<br />

considered the most damaging. As<br />

per the studies carried out under<br />

United States Country Study Program’s<br />

Initial National Communication<br />

and Climate Change Action Plan,<br />

the following estimates have been<br />

calculated:<br />

About 26 000m 2 <strong>of</strong> beaches could<br />

be flooded with a sea-level rise <strong>of</strong><br />

one metre in the region <strong>of</strong> Flic En<br />

Flac, a favourite tourist spot located<br />

to the west <strong>of</strong> Mauritius;<br />

About 12 km <strong>of</strong> main coastal road<br />

and 25 km <strong>of</strong> secondary coastal road<br />

could be permanently inundated;<br />

Plantations, including several<br />

hectares <strong>of</strong> sugar cane and cash<br />

crops could be inundated and have<br />

to be abandoned;<br />

More than 1 000 houses could be<br />

totally under threat and 100 units<br />

partly, resulting in an estimated<br />

6 000 people being affected.<br />

Storm surge and rising sea-level affect coastal roads.<br />

Warning <strong>of</strong> tsunami or seismic sea<br />

waves was inexistent in the country<br />

prior to the event <strong>of</strong> 26 December<br />

2004. The Government <strong>of</strong> Mauritius<br />

has recently established a<br />

tsunami warning centre at the Mauritius<br />

Meteorological Services. It is<br />

based on its experience in tropical<br />

cyclone warning and its interest in the<br />

collection and management <strong>of</strong> basic<br />

oceanographic parameters, with the<br />

collaboration <strong>of</strong> other national,<br />

regional and international organizations.<br />

The significant contributions<br />

from the World Meteorological Organization,<br />

the Intergovernmental<br />

Oceanographic Commission <strong>of</strong><br />

UNESCO, the Japan Meteorological<br />

Agency and the Pacific Centre<br />

Tsunami warning <strong>of</strong> Hawaii are hereby<br />

acknowledged.<br />

Being a small developing State, it has<br />

been observed that these types <strong>of</strong><br />

hazard could halt or even reverse the<br />

economic progress <strong>of</strong> Mauritius. A<br />

programmed and systematic<br />

approach to reduce vulnerability has<br />

become a government priority. The<br />

81


82<br />

Prime Minister’s Office thus set up<br />

the Central Cyclone and Other Natural<br />

Disaster Committee, including<br />

Tsunami. It focuses on disaster management<br />

by coordinating prevention/<br />

mitigation, preparedness and<br />

response strategies. The Mauritius<br />

Meteorological Services is the warning<br />

centre <strong>of</strong> all natural hazards affecting<br />

Mauritius and also plays a key role<br />

in sensitizing the population through a<br />

proactive awareness campaign, using<br />

the electronic and written media in<br />

collaboration with other stakeholders.<br />

Meteorological services and<br />

<strong>tourism</strong><br />

The <strong>tourism</strong> industry is likely to suffer<br />

from most hydrometeorological hazards,<br />

notably higher sea-levels and<br />

damage to coastal areas from surges,<br />

high waves and storms.<br />

In the light <strong>of</strong> these threats to coastal<br />

areas, an essential source <strong>of</strong> economy<br />

for the local <strong>tourism</strong> industry, the<br />

Mauritius Meteorological Services is<br />

committed to assume new responsibilities<br />

to meet the challenges, to<br />

<strong>of</strong>fer meteorological protection for the<br />

safety and security <strong>of</strong> tourists and to<br />

participate in various programmes to<br />

mitigate and rehabilitate the coastal<br />

assets.<br />

A two-way relationship between<br />

<strong>tourism</strong> and Mauritius Meteorological<br />

Services has been developed. It is<br />

gradually building a disaster-resilient<br />

<strong>tourism</strong> community through vital tools<br />

such as timely dissemination <strong>of</strong><br />

weather forecast and accurate forecasts.<br />

Most <strong>of</strong> the hotels and tourist<br />

residences are in direct liaison with<br />

the Mauritius Meteorological Services<br />

and, following an arrangement, automatically<br />

receive the daily weather<br />

forecasts.<br />

Water sports such as big game fishing,<br />

water skiing, diving, swimming<br />

and undersea walks are favourites <strong>of</strong><br />

the tourists. Mauritius Meteorological<br />

Services ensures that warnings for<br />

the high seas and the lagoon are disseminated<br />

well in advance to allow<br />

organization <strong>of</strong> these activities.<br />

The <strong>tourism</strong> industry is also informed<br />

<strong>of</strong> the presence <strong>of</strong> extreme weather<br />

events or natural hazards likely to<br />

affect Mauritius. This allows the<br />

tourist to be kept informed and organizers<br />

to cater for indoor leisure.<br />

Tourists are also encouraged at all<br />

times to phone the Mauritius Meteorological<br />

Services directly for pr<strong>of</strong>essional<br />

advice. Thousands <strong>of</strong> queries<br />

about the forecast weather conditions<br />

are requested annually by<br />

tourists by e-mail before leaving their<br />

homeland. Mauritius Meteorological<br />

Services ensures that such queries<br />

are treated within 24 hours <strong>of</strong> receipt.<br />

Seasonal climate forecasts are issued<br />

twice yearly and provided to the tour<br />

operators, the Ministry <strong>of</strong> Tourism,<br />

and policy-/decision-makers. This<br />

information is crucial for forward planning,<br />

development <strong>of</strong> the <strong>tourism</strong><br />

marketing strategy and to cater for<br />

tourists’ comfort.<br />

Mauritius Meteorological Services is<br />

an active member <strong>of</strong> the Integrated<br />

Coastal Zone Management (ICZM)<br />

Committee, which is responsible for<br />

giving guidance on sustainable<br />

coastal development. The basic<br />

requirements to achieve coastal protection<br />

and management are data on<br />

tides, water levels, waves, sea temperature,<br />

winds and coastal circulation.<br />

Mauritius Meteorological Services<br />

has installed two tide-gauges at<br />

Port Louis and Rodrigues to monitor<br />

sea-level since 1986. It also generates<br />

its own tidal forecasts and pub-<br />

lishes it in its annual technical report.<br />

It has installed a wave rider buoy just<br />

<strong>of</strong>f the lagoon to the south-east <strong>of</strong><br />

Blue Bay for wave recordings. These<br />

data are frequently used in models to<br />

calculate the impacts <strong>of</strong> waves on<br />

coastal areas.<br />

Data monitoring, archival and delivery<br />

have been major priorities for Mauritius<br />

Meteorological Services. It established<br />

the National Oceanographic<br />

Data and Information Centre (NODC)<br />

in 1999 and is involved in the compilation<br />

and manipulation <strong>of</strong> physical<br />

oceanographic and hydrometeorological<br />

data for Mauritius national waters.<br />

Conclusion<br />

Mauritius Meteorological Services is<br />

responding to new and growing<br />

demand at national level for the provision<br />

<strong>of</strong> vital inputs to the sustainable<br />

development <strong>of</strong> the <strong>tourism</strong> industry.<br />

Areas <strong>of</strong> observation, communication,<br />

warning services, maintenance <strong>of</strong><br />

quality-controlled databanks and<br />

access to them by potential users are<br />

being continuously enhanced to contribute<br />

more efficiently to development<br />

programmes. It is the ambition<br />

<strong>of</strong> Mauritius Meteorological Services<br />

that Mauritius will become prepared<br />

for natural hazards in order to promote<br />

the <strong>tourism</strong> industry. The continual<br />

support for the transfer <strong>of</strong> technology<br />

and capacity building from<br />

<strong>WMO</strong> has been invaluable.<br />

l applications<br />

for coastal<br />

management<br />

in Barbados<br />

By Lorna Inniss 1 , Antonio Rowe 2 ,<br />

General information about<br />

Barbados<br />

Barbados, the most easterly <strong>of</strong> the<br />

Caribbean islands, is located north-east<br />

<strong>of</strong> Venezuela at 13°N, 59°W, with a land<br />

area <strong>of</strong> approximately 432 km 2 . In spite<br />

<strong>of</strong> its relatively short coastline (92 km),<br />

the island’s coastal boundaries are quite<br />

diverse, influenced on the one side by<br />

the calm waters <strong>of</strong> the Caribbean Sea<br />

and, on the other, by the high-energy<br />

Atlantic Ocean waves. This coast is<br />

recognized by the Barbados Government<br />

as a unique and irreplaceable asset<br />

and one requiring sustained protection<br />

and conservation measures.<br />

The dry sub-humid climate <strong>of</strong> Barbados<br />

produces temperatures in the range<br />

20°–30°C. The dry season, which is<br />

normally quite distinct, is from<br />

December to May, with the balance <strong>of</strong><br />

the year being quite wet. Average<br />

annual rainfall ranges from 1 254 mm at<br />

lower elevations to 1 650 mm at higher<br />

central elevations. The island is almost<br />

completely dependent on groundwater<br />

abstracted from the aquifer underlying<br />

the island.<br />

Karst topography characterizes the<br />

island generally. However, the northeastern<br />

coastal area is comprised <strong>of</strong><br />

sedimentary deposits. It is unclear<br />

whether the limestone cap has been<br />

removed from these deposits over<br />

geological time. The resultant landscape<br />

in this area is unique but highly prone to<br />

land slippage and erosion. It is this area<br />

which faces the high-energy waves <strong>of</strong><br />

the Atlantic Ocean and the trade winds.<br />

Reef development is minimal <strong>of</strong>fshore<br />

but large pockets <strong>of</strong> limestone flats<br />

exist, dominated by sea fans. In<br />

contrast, the Caribbean coast is characterized<br />

by protected bays and lengthy<br />

beaches along usually calm coastlines.<br />

These Caribbean coasts south and west<br />

<strong>of</strong> the island are the main foci <strong>of</strong> <strong>tourism</strong>,<br />

the current main economic driver.<br />

Mostly thriving fringing and bank reefs<br />

are the basis for the development <strong>of</strong><br />

diving <strong>tourism</strong>, as well as local recreational<br />

activities.<br />

The coastal zone management<br />

programme has evolved mainly in<br />

response to the need for coastal<br />

conservation in respect <strong>of</strong> <strong>tourism</strong>.<br />

During the 1980s, owners <strong>of</strong> coastal<br />

hotels realized that many <strong>of</strong> the<br />

Caribbean beaches were eroding. They<br />

initiated discussions with the<br />

Government to ensure that this trend<br />

was reversed or at least stabilized.<br />

Tourism, however, was not the only<br />

driver in the establishment <strong>of</strong> the coastal<br />

zone management programme. The<br />

majority <strong>of</strong> critical infrastructure in<br />

Barbados is located along the coastline.<br />

Government headquarters, healthcare<br />

facilities, fire stations and electrical installations<br />

are located within the coastal<br />

zone. The vulnerability <strong>of</strong> these facilities,<br />

as well as the extensive <strong>tourism</strong> plant,<br />

led the Government to seek a comprehensive,<br />

integrated coastal zone<br />

management paradigm, which led to the<br />

establishment <strong>of</strong> the Coastal Conservation<br />

Project Unit in 1983.<br />

The coastal zone management programme<br />

focuses mainly on shoreline<br />

stabilization through the use <strong>of</strong> coastal<br />

Introduction<br />

A basic understanding <strong>of</strong> marine and<br />

coastal <strong>meteorology</strong> is an important<br />

component in coastal and <strong>of</strong>fshore<br />

design and planning. One <strong>of</strong> the most<br />

important meteorological considerations<br />

relates to the dominant role <strong>of</strong> winds in<br />

wave generation. This is critical in wave<br />

climate analysis which is fundamental,<br />

and one <strong>of</strong> the most critical elements in<br />

the design <strong>of</strong> coastal structures.


However, many other meteorological<br />

processes (e.g. the role <strong>of</strong> winds in dune<br />

formation, precipitation, wind-driven<br />

coastal currents and surges, direct wind<br />

forces on structures; atmospheric circulation<br />

<strong>of</strong> pollution and salt) are also<br />

important environmental factors to<br />

consider in man’s interaction with nature<br />

in this sometimes fragile, sometimes<br />

harsh, environment.<br />

Barbados wave climate analysis<br />

The Government <strong>of</strong> Barbados is currently<br />

undertaking a Coastal Infrastructure<br />

Programme. This comprises a range <strong>of</strong><br />

coastal management works and activities<br />

related to four specific objectives:<br />

Shoreline stabilization and erosion<br />

control<br />

Restoration <strong>of</strong> coastal habitats<br />

Improvement <strong>of</strong> public coastal access<br />

Institutional strengthening for coastal<br />

management<br />

A comprehensive wave climate investigation<br />

the Coastal Infrastructure Programme.<br />

The information generated from this<br />

analysis was subsequently used as input<br />

for detailed numerical and physical modelling<br />

<strong>of</strong> the various project sites (Figure 1).<br />

Wave-generation mechanisms<br />

Barbados is impacted by three distinct<br />

types <strong>of</strong> wave conditions, which may be<br />

identified as shown in Figure 2:<br />

Locally generated seas<br />

These are waves created primarily by<br />

the north-eastern trades blowing in<br />

the vicinity <strong>of</strong> Barbados.<br />

Longer period swells<br />

These swells are generated by extratropical<br />

cyclones occurring in the<br />

mid-latitudes <strong>of</strong> the North Atlantic.<br />

They are particularly important as,<br />

due to their long periods (>12 s),<br />

they have the potential to “wrap”<br />

around the island <strong>of</strong> Barbados and<br />

be present on southern shorelines.<br />

The season for the extra-tropical<br />

cyclones traversing the North<br />

Atlantic Ocean is mostly from<br />

November to March.<br />

Hurricanes (tropical cyclones) are<br />

large-scale, severe storm events<br />

that may be generated in the northern<br />

equatorial belt and may pass in a<br />

general east-to-west direction over,<br />

and in the vicinity <strong>of</strong>, the island <strong>of</strong><br />

Barbados. These events can generate<br />

very large wave conditions and<br />

significant surge and form the basis<br />

<strong>of</strong> the extreme design conditions at<br />

each <strong>of</strong> the project sites. The season<br />

for tropical cyclones in the Caribbean<br />

Sea is from May to November, with<br />

peak activity occurring during<br />

September and October.<br />

Accurately predicting the range in<br />

wave heights, wave periods and, in<br />

particular, wave direction, is an essential<br />

input to any coastal engineering<br />

investigation, particularly with respect<br />

to sediment-<strong>transport</strong> modelling and<br />

understanding beach platform development.<br />

Wave climate analyses for<br />

the Caribbean are <strong>of</strong>ten separated into<br />

operational (daily or non-hurricane)<br />

wave conditions and design (hurricane)<br />

wave conditions. The<br />

methodologies for investigation <strong>of</strong><br />

both phenomena vary because <strong>of</strong> the<br />

differences in scale <strong>of</strong> these wave<br />

processes (Baird, 2005).<br />

Long-term wave hindcast for<br />

Barbados<br />

In order to quantify the wave climate <strong>of</strong><br />

Barbados, a 20-year numerical wave<br />

hindcast <strong>of</strong> the North Atlantic Ocean<br />

was undertaken, using a 2D spectral<br />

hindcast wind-wave model. The basic<br />

input to the hindcast model consists <strong>of</strong><br />

a regular spaced grid defining the water<br />

depths and shorelines in the region <strong>of</strong><br />

interest, and temporal and spatially varying<br />

wind fields. The model produces as<br />

output a detailed description <strong>of</strong> wave<br />

conditions throughout the model<br />

domain that varies with time over the<br />

period <strong>of</strong> the hindcast.<br />

A 20-year hindcast <strong>of</strong> deepwater wave<br />

conditions was carried out using the<br />

hindcast model WAVAD. WAVAD is a<br />

second generation directional spectral<br />

wave model developed by Don Resio <strong>of</strong><br />

the US Army Corps <strong>of</strong> Engineers. The<br />

model has also been extensively tested<br />

and verified at a range <strong>of</strong> sites throughout<br />

the world.<br />

This model includes a parameterization<br />

for the wave generation and development<br />

mechanism that uses wind data<br />

provided from a global atmospheric<br />

model. The objective <strong>of</strong> these simulations<br />

was to define a long-term database<br />

<strong>of</strong> operational wave conditions <strong>of</strong>fshore<br />

<strong>of</strong> Barbados.<br />

85


86<br />

Model validation for the wave hindcast<br />

carried out for Barbados was undertaken<br />

primarily through comparison <strong>of</strong><br />

the hindcast results with a deepwater<br />

wave buoy (41 100) located northeast<br />

<strong>of</strong> Barbados and maintained by Météo-<br />

France.<br />

The wave hindcast carried out for<br />

Barbados involved a two-stage process.<br />

A coarse outer grid with a 1° (111 km)<br />

spatial resolution was used to simulate<br />

wave conditions throughout the North<br />

Atlantic Ocean. The results from the<br />

simulation were then used to define the<br />

boundary conditions for the finer 0.25°<br />

(27.75 km) resolution nested grid that<br />

covered the south-eastern Caribbean.<br />

The purpose <strong>of</strong> nesting grids was to<br />

account for the effects <strong>of</strong> sheltering<br />

from western islands, thus improving<br />

the accuracy <strong>of</strong> the hindcast.<br />

Figure 3 shows a typical snapshot <strong>of</strong><br />

model output for wave conditions in the<br />

Atlantic Ocean. The colour contours<br />

reflect the characteristic wave height<br />

over the model grid ranging from 0 (blue)<br />

to 10 m height (red). The vectors indicate<br />

the mean direction <strong>of</strong> wave<br />

propagation.<br />

Tropical cyclones are intense and<br />

compact storm systems. The grid spacing<br />

<strong>of</strong> the global atmospheric model is<br />

relatively coarse at 1 875° or (approxi-<br />

mately) 208 km (Figure 4). As a result,<br />

the atmospheric model typically underestimates<br />

the intensity <strong>of</strong> the wind fields<br />

for tropical cyclone events. To account<br />

for this, the tropical cyclone events that<br />

occurred over the past 20 years were<br />

considered separately (Baird, 2005).<br />

Offshore wave climate<br />

Figure 2 — Wavegeneration<br />

mechanisms (Source:<br />

Barbados Wave<br />

Climate Analysis,<br />

Wave conditions at Barbados were<br />

extracted from a representative<br />

location within the model for the final<br />

20-year hindcast. Statistics on these<br />

wave conditions were then<br />

generated in the form <strong>of</strong> scatter<br />

tables and a storm selection. Figure 6<br />

presents a wave rose, illustrating the<br />

variation <strong>of</strong> wave height by frequency<br />

and direction, based on all the<br />

available wave data.<br />

As may be noted in the figure, the<br />

predominant waves occur primarily<br />

from the north-east to east sectors.<br />

The maximum, minimum and mean<br />

hourly significant wave heights at<br />

this location, based on the findings<br />

from the hindcast were 6.33 m,<br />

O.66 m and 1.93 m respectively<br />

(Baird, 2005).<br />

Coastal engineering structures<br />

design water levels<br />

Having obtained the <strong>of</strong>fshore wave<br />

climate information, the following steps<br />

are undertaken to obtain the design<br />

water levels used in the design <strong>of</strong><br />

coastal engineering structures:<br />

– Analysis <strong>of</strong> historical hurricane data;<br />

– Numerical simulation <strong>of</strong> waves<br />

<strong>of</strong> simulations were integrated<br />

into the nearshore operational<br />

wave climate at selected project<br />

sites;<br />

These data were subsequently<br />

utilized to derive the design wave<br />

climate by return period for<br />

selected project sites;<br />

Storm-surge modelling: to simulate<br />

the impact <strong>of</strong> storm surge at the project<br />

sites in Barbados. The<br />

two-dimensional hydrodynamic model<br />

ADCIRC 2DDI was developed by the<br />

US Army Corps <strong>of</strong> Engineers;<br />

Water-level determination: as the<br />

sites are located in shallow,<br />

nearshore waters, where wave<br />

conditions are depth-limited,<br />

estimation <strong>of</strong> water level is a critical<br />

aspect in the design wave climate<br />

definition. The components<br />

considered were tidal variation,<br />

long-term sea-level rise and wave<br />

set-up.<br />

Design conditions were then established<br />

at each site for the 50-year<br />

return period.<br />

Use <strong>of</strong> satellites in coral reef<br />

research in Barbados<br />

Background<br />

While satellites are able to perform a<br />

host <strong>of</strong> different functions, their ability<br />

to differentiate wavelengths <strong>of</strong> light<br />

and measure thermal radiation makes<br />

them invaluable in coral-reef research.<br />

Satellites are being used to map coral<br />

reefs, detect plankton blooms and<br />

determine likely sources <strong>of</strong> nutrient<br />

enrichment. This is possible as a result<br />

<strong>of</strong> the different spectral properties that<br />

exist.<br />

Satellites are also used in coral-reef<br />

monitoring, providing information<br />

pertaining to reef health. It is perhaps<br />

fortuitous that the manner in which<br />

corals react to stressors, e.g. bleaching,<br />

and the stressors themselves, e.g.<br />

high temperatures, can be measured<br />

by satellites. As a result, these are<br />

becoming increasingly important in<br />

coral research.<br />

Aqua and Terra satellites<br />

Two <strong>of</strong> the multi-use satellites are<br />

Aqua and Terra, the main parts <strong>of</strong><br />

NASA’s Earth Observing System (EOS)<br />

<strong>of</strong> satellites. Both are Sun-synchronous<br />

satellites, which allow scientists from<br />

all over the world to measure the<br />

Earth’s oceans, land, ice and biology.<br />

They contain several instruments,<br />

including CERES (monitoring cloud<br />

cover and radiant energy) and MODIS<br />

(moderate resolution imaging spectroradiometer).<br />

Terra also carries MISR<br />

(monitoring aerosols and reflected<br />

sunlight), MOPITT (measuring pollution<br />

in the troposphere) and ASTER (measuring<br />

land-surface climatology,<br />

vegetation and ecosystem dynamics).<br />

It is MODIS, however, that is most<br />

relevant to coral-reef science. MODIS<br />

was developed by NASA to investigate<br />

global dynamics and processes occur-<br />

Figure 6 — Wave-height rose <strong>of</strong>fshore from Barbados (Source: Barbados Wave Climate<br />

Analysis, Baird 2005)<br />

ring on the land, in the oceans, and in<br />

the lower atmosphere. It views the<br />

entire Earth once every two days or<br />

so. The instrument takes measurements<br />

in the visible and infrared<br />

radiation bands, and transmits the<br />

data back to NASA for processing and<br />

distribution.<br />

The importance <strong>of</strong> MODIS lies in its<br />

ability to measure ocean colour, which<br />

changes according to the amount <strong>of</strong><br />

biological activity in the upper layer <strong>of</strong><br />

the ocean. The SeaWifs (sea-viewing<br />

side field-<strong>of</strong>-view sensor) instrument<br />

is another satellite-based platform for<br />

measuring ocean colour but with a<br />

lower resolution than MODIS.<br />

Another satellite aiding coral-reef<br />

researchers is the NOAA-17 satellite<br />

which carries the AVHRR (advanced<br />

very high resolution radiometer)<br />

instrument. This sensor operates in<br />

several bands <strong>of</strong> visible and infrared to<br />

observe the surface <strong>of</strong> the Earth (i.e.<br />

land, ocean or clouds). The AVHRR’s<br />

main role is to observe cloud cover<br />

and derive surface temperature for<br />

NOAA weather modelling and stormtracking<br />

programmes. The infrared<br />

sensors, however, also measure seasurface<br />

temperatures (SSTs) across<br />

the globe.<br />

Meteorology’s expanding role in<br />

coral science<br />

Five areas <strong>of</strong> coral-reef science in which<br />

<strong>meteorology</strong> is playing an increasingly<br />

larger role are:<br />

Coral bleaching<br />

Phytoplankton blooms<br />

Coral disease (aspergillosis)<br />

Land-based sources <strong>of</strong> marine<br />

pollution<br />

Coral mapping<br />

Bleaching<br />

Corals depend on the symbiotic relationship<br />

between themselves and their<br />

din<strong>of</strong>lagellate micro-algae (zooxanthellae)<br />

to survive. The pairing is mutually<br />

beneficial, with the algae supplying their<br />

photosynthetic products <strong>of</strong> sugars and<br />

amino acids to the corals, which, in turn,<br />

release their waste products <strong>of</strong> ammonia<br />

and phosphate (essential plant<br />

nutrients) to the micro-algae.<br />

The loss <strong>of</strong> zooxanthellae from coral or<br />

the loss <strong>of</strong> the photosynthetic pigment<br />

from the zooxanthellae itself is termed<br />

bleaching. It results in the coral appearing<br />

white as the colour <strong>of</strong> the limestone<br />

skeleton becomes visible (Porter and<br />

Tougas, 2001). Temperature-induced<br />

bleaching can occur, either as a result<br />

<strong>of</strong> being exposed to high temperatures<br />

for short periods <strong>of</strong> time, e.g 1.5–2°C<br />

above summer temperatures for several<br />

days, or for longer exposure to slightly<br />

elevated temperatures, e.g. 1–1.5°C<br />

above normal for three to four weeks.<br />

A bleached coral has reduced capacity<br />

to feed and build its skeleton. If the<br />

stress continues, the coral will be unable<br />

to meet its nutritional requirements and<br />

mortality will result.<br />

Corals appear to be at serious risk from<br />

bleaching events. In the past 20 years<br />

alone, mass coral mortalities from every<br />

region in the world have been reported<br />

as a result <strong>of</strong> bleaching, with the most<br />

severe case in 1998 (Hoegh-Guldberg,<br />

1999). It is estimated that this bleaching<br />

event reduced live coral cover by 10 per<br />

cent (Hodgson and Liebeler, 2002).<br />

More recently, a Caribbean-wide mass<br />

bleaching event occurred in 2005, with<br />

temperatures reaching 31°C, and a<br />

mean 59 per cent—86 per cent <strong>of</strong> all<br />

hard corals in Barbados—being affected<br />

(Oxenford et al., in press).<br />

The NOAA-17 satellite is therefore <strong>of</strong><br />

interest to coral-reef scientists tracking<br />

bleaching, as it allows them to remotely


indicate the likely severity <strong>of</strong> coral<br />

bleaching events, a phenomenon<br />

directly linked to ocean-water temperatures.<br />

SST data are also used to track El<br />

Niño and La Niña weather patterns,<br />

which have implications both for storm<br />

activity, as well as for the length <strong>of</strong><br />

ocean heating periods, both <strong>of</strong> which<br />

have negative impacts on coral reefs.<br />

Phytoplankton blooms<br />

Phytoplankton are drifting, microscopic<br />

aquatic plants, which are important both<br />

in and out <strong>of</strong> water, forming the first<br />

level <strong>of</strong> the marine food chain, and<br />

producing approximately half the oxygen<br />

inhaled by living organisms on Earth.<br />

Phytoplankton contains chlorophyll, an<br />

important element <strong>of</strong> photosynthesis<br />

and also one <strong>of</strong> the most significant<br />

light-altering substances. This chlorophyll<br />

(which is also readily detected by<br />

satellites) absorbs the red and blue<br />

portion <strong>of</strong> light and reflects green, so the<br />

more phytoplankton, the greener the<br />

water and the fewer phytoplankton, the<br />

bluer the water.<br />

High concentrations <strong>of</strong> phytoplankton<br />

can indicate both positive and negative<br />

conditions. Very high concentrations <strong>of</strong><br />

plankton (for instance, during plankton<br />

blooms) indicate that excessive quantities<br />

<strong>of</strong> nutrients are in the area. This is<br />

detrimental to coral reefs as eutrophication<br />

encourages algal overgrowth and<br />

the physical presence <strong>of</strong> algae in<br />

nearshore areas can block out sunlight,<br />

resulting eventually in mortality.<br />

Additionally, a bloom event where there<br />

has been little flushing can result in<br />

anoxic conditions causing “dead zones”<br />

devoid <strong>of</strong> life. Finally, toxic blooms can<br />

fatally poison flora and fauna in their<br />

vicinity. On the other hand, phytoplankton<br />

utilizes CO 2 , one <strong>of</strong> the greenhouse<br />

gases. Large populations sustained over<br />

periods <strong>of</strong> time can actually significantly<br />

lower atmospheric CO 2 , which, in turn,<br />

could result in a lowering <strong>of</strong> average<br />

temperatures.<br />

MODIS and the less accurate SeaWifs<br />

space-borne instruments can detect<br />

the quantity <strong>of</strong> chlorophyll and are<br />

used to track these blooms and determine<br />

their extent. Information can<br />

also be gathered on possible causes<br />

<strong>of</strong> the bloom which would allow for<br />

changes in policy or practices to minimize<br />

future events.<br />

Disease (Sahara dust and<br />

aspergillosis)<br />

It has been hypothesized that Sahara<br />

dust (particulates in the upper atmosphere<br />

originating in Saharan Africa)<br />

has a negative impact on coral-reef<br />

health. The lifting <strong>of</strong> desert soil by<br />

large storm events or high-speed<br />

winds is not uncommon, and can<br />

result in soils reaching in excess <strong>of</strong> 10<br />

km into the air. Duststorms which<br />

originate in Africa typically move<br />

across the Atlantic and reach the<br />

Caribbean, Central America and the<br />

south-eastern USA between June and<br />

October. In the northern hemisphere<br />

winter, the dust tends to hit South<br />

America and Trinidad between<br />

February and April (Griffin et al.,<br />

2001).<br />

It is theorized that the decline <strong>of</strong><br />

Caribbean coral reefs is partially as a<br />

result <strong>of</strong> this phenomena (Griffin et al.<br />

2001). Research on Saharan dust has<br />

been carried out in Barbados by the<br />

University <strong>of</strong> Miami since 1965. The<br />

first documented cases <strong>of</strong> coral disease<br />

occurrence appear to correspond with<br />

the onset <strong>of</strong> desertification in North<br />

Africa in the 1970s. The onset <strong>of</strong><br />

climate change is theorized to have<br />

resulted in African dust being <strong>transport</strong>ed<br />

in a westerly direction over the<br />

Atlantic to the Caribbean. These data<br />

are clearly shown in dust records in<br />

Barbados (Prospero and Nees, 1986).<br />

Data collected from Prospero show that<br />

the peak dust deposition years, 1983<br />

and 1987, correspond to severe deterioration<br />

<strong>of</strong> coral reefs in the Caribbean<br />

caused by Black band and White band<br />

disease. It is thought that dust can affect<br />

coral reefs by direct fertilization <strong>of</strong> algae<br />

by iron or other nutrients interacting with<br />

nutrient-rich ground water and by broadcasting<br />

bacterial, viral and fungal spores.<br />

However, the strongest evidence<br />

supporting the theory <strong>of</strong> the link<br />

between dust and coral disease is the<br />

identification <strong>of</strong> the fungus Aspergillus<br />

sydowii (which does not reproduce in<br />

sea-water) as the infectious agent in<br />

Caribbean sea-fan mortality (Weir et al.,<br />

2000).<br />

MODIS is the primary system by which<br />

researchers monitor Sahara dust, as the<br />

sensor can distinguish haze (aerosols)<br />

from clouds. Monitoring the movement<br />

<strong>of</strong> the dust can indicate likely areas <strong>of</strong><br />

impact for coral diseases.<br />

Mapping<br />

Satellites are becoming more widely<br />

used in producing baseline cartographic<br />

maps, mapping reef geomorphology<br />

and habitats. While much success has<br />

been made in the former two, the determination<br />

<strong>of</strong> ecological characteristics<br />

has proved to be more difficult. Limited<br />

information can be obtained, in broad<br />

categories, such as sand, algae, sea<br />

grass and coral. With CASI (compact<br />

airborne spectographic image), 80 per<br />

cent accuracy can be obtained, while<br />

Landsat and SPOT (Satellite pour l’observation<br />

de la Terre) are among the<br />

most widely used satellites for mapping<br />

because <strong>of</strong> their cost-effectiveness.<br />

Challenges<br />

A number <strong>of</strong> challenges still exist for<br />

the complete incorporation <strong>of</strong><br />

<strong>meteorology</strong> into the Barbados<br />

89


90<br />

programme. The Barbados<br />

Meteorological Services, located at<br />

the island’s airport, reports only on<br />

rainfall recorded at that location, even<br />

though a number <strong>of</strong> other raingauges<br />

and weather stations are located<br />

around the island. As a result, huge<br />

inaccuracies occur during the<br />

application <strong>of</strong> rainfall data for coasts<br />

opposite the airport.<br />

Models utilized for measuring seasurface<br />

height are now dated, leading<br />

to the general warnings to coastal<br />

users and fishermen “above normal<br />

sea swells”, even in cases where the<br />

swells in question are 7 m above<br />

normal. Barbados experienced high<br />

storm surge associated with hurricane<br />

Ivan. However, the meteorologists<br />

were limited in their warnings to<br />

rainfall and wind changes. If hurricane<br />

seasons continue to be intense, it is<br />

imperative that the coastal<br />

programme work with meteorologists<br />

to improve predictions with respect to<br />

potential coastal impacts. Coastal<br />

evacuation planning and development<br />

plans are based on these forecasts,<br />

requiring a high degree <strong>of</strong> accuracy in<br />

the data used. The coastal<br />

engineering programme depended on<br />

external expertise for training and<br />

assistance until capacity was built<br />

within the Unit. Now there must be<br />

interministerial collaboration to ensure<br />

that other departments, such as the<br />

Meteorological Services, also benefit<br />

from the expertise within the coastal<br />

management programme, further<br />

benefiting society as a whole.<br />

dispatchers and air traffic controllers<br />

need to have observations, reports<br />

and forecasts as well as warnings <strong>of</strong><br />

such phenomena. What is <strong>of</strong>ten less<br />

clear is the important effect that<br />

seemingly “innocent” meteorological<br />

elements (such as surface and<br />

upper winds, visibility and runway<br />

visual range, temperatures and<br />

surface pressure) can have on both<br />

the safety and efficiency <strong>of</strong> flight<br />

operations.<br />

Information on wind direction and<br />

speed is vital for take-<strong>of</strong>f and landing.<br />

The selection <strong>of</strong> the runway is<br />

based on that element. If the heador<br />

tail-wind component and the<br />

cross-wind components are made<br />

available separately, the length <strong>of</strong><br />

runway needed for take-<strong>of</strong>f or landing<br />

can be determined. One can also<br />

ascertain whether the cross-wind<br />

component falls within the design<br />

limits <strong>of</strong> individual aircraft. Normally,<br />

aircraft land or take <strong>of</strong>f into a head<br />

wind; a cross-wind component <strong>of</strong><br />

the order <strong>of</strong> 46-56 km/h is the maximum<br />

permissible for the majority <strong>of</strong><br />

jet aircraft. The cross-wind limit for<br />

small aircraft is generally lower than<br />

these values. For the en-route phase<br />

<strong>of</strong> flight, information is required on<br />

winds along the route at cruising<br />

levels. Strong head winds mean that<br />

more fuel needs to be carried at the<br />

expense <strong>of</strong> passengers or freight.<br />

Pilots need to know what the<br />

temperature will be at their flight<br />

level because temperature affects<br />

jet engine efficiency (in general, the<br />

lower the better). The same applies<br />

during take-<strong>of</strong>f: a higher temperature<br />

results in a longer take-<strong>of</strong>f run<br />

because temperature affects the<br />

density <strong>of</strong> the air (i.e. the higher the<br />

temperature, the lower the density).<br />

Temperature affects the lift at a<br />

given speed and hence also affects<br />

the take-<strong>of</strong>f run. Similarly, the atmospheric<br />

pressure affects the take-<strong>of</strong>f<br />

run due to its relationship with the<br />

density <strong>of</strong> the air.<br />

The surface wind, temperature and<br />

pressure referred to above have to be<br />

accounted for in the pre-flight calculations<br />

<strong>of</strong> the take-<strong>of</strong>f run, i.e. the<br />

calculation <strong>of</strong> maximum permissible<br />

take-<strong>of</strong>f weight for the runway under<br />

the given meteorological conditions.<br />

The provision <strong>of</strong> accurate and timely<br />

information on these meteorological<br />

elements helps ensure the safety <strong>of</strong><br />

flight and also improves the efficiency<br />

<strong>of</strong> airline operations.<br />

Information on visibility and runway<br />

visual range is <strong>of</strong> critical importance as<br />

landing and take-<strong>of</strong>f minima are determined<br />

on the basis <strong>of</strong> these elements,<br />

and precision approach operations<br />

cannot take place without them.<br />

Furthermore, the height <strong>of</strong> the cloud<br />

base is highly useful when assessing<br />

whether the prevailing conditions are<br />

above the landing and take-<strong>of</strong>f minima<br />

and whether the pilot is in a position to<br />

establish the required visual reference<br />

at the decision altitude. This information<br />

has become increasingly<br />

important as the number <strong>of</strong> aircraft<br />

The turbulence associated with<br />

thunderstorms can exceed the structural<br />

limits <strong>of</strong> the aircraft.<br />

91


92<br />

operations increase in lower-visibility<br />

conditions.<br />

With regard to hazardous weather<br />

phenomena for take-<strong>of</strong>f or landing,<br />

pilots need to be warned <strong>of</strong> the existence<br />

or forecast <strong>of</strong> fog, snowstorms,<br />

wind shear, tropical cyclones, etc.<br />

During the en-route phase <strong>of</strong> flight,<br />

pilots need to know whether they are<br />

likely to encounter severe thunderstorms,<br />

involving hail, severe<br />

turbulence, icing or volcanic ash to<br />

enable them to avoid these hazardous<br />

phenomena. Thunderstorms are notorious<br />

for extreme up- and<br />

downdraughts. Pilots avoid thunderstorms<br />

as much as they can because<br />

the associated turbulence can easily<br />

exceed the structural limits <strong>of</strong> the<br />

aircraft. Moreover, thunderstorms are<br />

particularly dangerous in the vicinity <strong>of</strong><br />

aerodromes as the associated downdraughts<br />

(in extreme cases called<br />

downbursts) can cause aircraft to sink<br />

below the glide path. This may mean<br />

that the aircraft could strike an obstacle<br />

or the ground before it can regain<br />

its flight path.<br />

Explosive volcanic eruptions produce<br />

clouds <strong>of</strong> dense ash up to levels reaching<br />

into the stratosphere. When the<br />

ash is ingested into aircraft jet<br />

Pilots need to be<br />

aware <strong>of</strong> existing or<br />

forecast snow for<br />

take-<strong>of</strong>f and landing<br />

operations. (Photo:<br />

engines, these are severely damaged<br />

and may flame-out completely, as has<br />

happened on at least three separate<br />

occasions. This is a serious hazard to<br />

aviation and has been addressed over<br />

the last few years by the International<br />

Civil Aviation Organization (ICAO), in<br />

coordination with <strong>WMO</strong>.<br />

The Global Observing System (GOS) is<br />

the <strong>WMO</strong> system for observing,<br />

recording and reporting meteorological<br />

conditions. This is essential for the<br />

preparation <strong>of</strong> operational forecasts and<br />

warnings for all users, including aviation.<br />

It makes a substantial contribution<br />

to enabling the delivery <strong>of</strong> increasingly<br />

accurate and reliable forecasts and<br />

warnings. The 187 Members <strong>of</strong> <strong>WMO</strong><br />

support and maintain the GOS and thus<br />

contribute to the meteorological information<br />

which is provided to<br />

aeronautical users. These include<br />

pilots, dispatchers, air-traffic controllers<br />

and airport and airline managers.<br />

<strong>WMO</strong> and ICAO working<br />

arrangements and the roles<br />

<strong>of</strong> the two Organizations<br />

In order to meet the needs <strong>of</strong> international<br />

civil aviation in an efficient<br />

manner, it is important that ICAO and<br />

<strong>WMO</strong> work closely together and<br />

ensure that stated aviation requirements<br />

can be met without any<br />

unnecessary overlap <strong>of</strong> activities<br />

carried out by the two Organizations.<br />

This has been recognized from the<br />

early days <strong>of</strong> aviation and that is the<br />

reason why working arrangements<br />

between <strong>WMO</strong> and ICAO were established<br />

as early as in 1953 and are<br />

included in the Working arrangements<br />

between the <strong>WMO</strong> and ICAO (ICAO<br />

Doc 7475 and <strong>WMO</strong>-No. 60). These<br />

working arrangements can be encapsulated<br />

by the following:<br />

ICAO is responsible for defining the<br />

aeronautical meteorological requirements;<br />

and<br />

<strong>WMO</strong> is responsible for defining the<br />

most appropriate methods for fulfilling<br />

the requirements, including the<br />

training <strong>of</strong> aeronautical meteorological<br />

personnel.<br />

It is important to note that the dissemination<br />

<strong>of</strong> operational meteorological<br />

(OPMET) data (e.g. METAR/SPECI,<br />

TAF, WAFS forecasts) is the prerogative<br />

<strong>of</strong> ICAO and that the planning for<br />

such dissemination is undertaken by<br />

ICAO. Furthermore, the provisions in<br />

Annex 3/Technical Regulations [C.3.1]<br />

stipulate that the ICAO aeronautical<br />

fixed service should be used for the<br />

dissemination <strong>of</strong> such information.<br />

One <strong>of</strong> the constant challenges facing<br />

both the ICAO and <strong>WMO</strong> Secretariats<br />

is to ensure that the work (i.e. the<br />

maintenance <strong>of</strong> up-to-date requirements<br />

by ICAO and methods for<br />

meeting those requirements by<br />

<strong>WMO</strong>) is carried out in an efficient<br />

and cost-effective manner. To this<br />

end, proper coordination between the<br />

two Organizations has to be<br />

constantly maintained with full<br />

consultation and cooperation at every<br />

stage <strong>of</strong> the process. This coordination<br />

is also achieved by the


systematic participation <strong>of</strong> <strong>WMO</strong> in<br />

the work <strong>of</strong> ICAO operations and study<br />

groups, and <strong>of</strong> ICAO in the work <strong>of</strong> the<br />

relevant <strong>WMO</strong> technical commissions.<br />

This ensures that:<br />

No aviation requirement is generated<br />

that is impossible to fulfil;<br />

No methodology is developed for a<br />

requirement that is not foreseen to<br />

exist; and<br />

Both Organizations continue to operate<br />

according to the Working<br />

arrangements between ICAO and<br />

<strong>WMO</strong> so as to avoid the duplication<br />

<strong>of</strong> effort and redundancy <strong>of</strong> services<br />

and facilities established for international<br />

civil aviation by their<br />

respective Members.<br />

The meteorological requirements for<br />

international air navigation are laid out<br />

in Annex 3—Meteorological service<br />

for international air navigation to the<br />

Convention on International Civil<br />

Aviation, which is a document maintained<br />

by ICAO. Annex 3 is also<br />

issued, mutatis mutandis, by <strong>WMO</strong> as<br />

Technical Regulations [C.3.1], i.e. a<br />

document identical to ICAO Annex 3<br />

except for a few minor details involving<br />

terminology that do not alter the<br />

substance <strong>of</strong> the document.<br />

The various chapters <strong>of</strong> Annex 3/<br />

Technical Regulations [C.3.1] outline<br />

the overall responsibilities <strong>of</strong> the<br />

designated meteorological authority<br />

for the provision <strong>of</strong> services and facilities<br />

for international air navigation. The<br />

associated appendices in Annex 3/<br />

Technical Regulations [C.3.1] provide<br />

the detailed specifications for use by<br />

those actually providing these services.<br />

The areas covered include<br />

aerodrome observations and forecasts,<br />

warnings (both in the terminal<br />

area and en-route), forecasts for enroute<br />

issued by the World Area<br />

Forecast Centres (London and<br />

Washington), advisories for volcanic<br />

ash and tropical cyclones, air reporting,<br />

needs for meteorological information<br />

by air traffic service units and communications<br />

requirements.<br />

A number <strong>of</strong> other documents are<br />

issued as guidance material by ICAO<br />

and <strong>WMO</strong> in order to provide ICAO<br />

Contracting States and <strong>WMO</strong><br />

Members with additional information<br />

to assist them in implementing the<br />

provisions contained in Annex 3/<br />

Technical Regulations [C3.1]. A<br />

complete list <strong>of</strong> ICAO and <strong>WMO</strong><br />

Manuals and Guides are available from<br />

the ICAO and <strong>WMO</strong> Websites at<br />

www.icao.int and www.wmo.int,<br />

respectively.<br />

In accordance with the working<br />

arrangements between the two<br />

Organizations, major amendments to<br />

Annex 3 are developed by conjoint<br />

ICAO/<strong>WMO</strong> meetings. Between<br />

EUROCONTROL and the<br />

Single European Sky<br />

Since 2001, air traffic management<br />

in the European Union (EU)<br />

is undertaken by Member States,<br />

cooperating through EURO-<br />

CONTROL, an intergovernmental<br />

organization comprising EU<br />

Member States and most other<br />

European States.<br />

The Single European Sky initiative<br />

is intended to organize airspace<br />

and air navigation at a European<br />

rather than at a local level. It will<br />

organize this airspace uniformly,<br />

with air traffic control areas based<br />

on operational efficiency, not<br />

national borders, integrating civil<br />

and military air traffic<br />

management.<br />

conjoint meetings, most <strong>of</strong> the<br />

proposed amendments to Annex 3/<br />

Technical Regulations [C.3.1] are<br />

developed by the ICAO Secretariat<br />

with the assistance <strong>of</strong> ICAO operations<br />

and study groups. These are<br />

composed <strong>of</strong> experts nominated by<br />

States and international organizations,<br />

including <strong>WMO</strong>.<br />

Currently, there are six such groups<br />

working on the World Area Forecast<br />

System satellite distribution system<br />

for information relating to air navigation<br />

(SADIS), international airways<br />

volcano watch, wind shear, automatic<br />

meteorological observing systems and<br />

the use <strong>of</strong> data link for the uplink and<br />

downlink <strong>of</strong> meteorological information.<br />

All draft amendments developed<br />

by these groups are sent for consultation<br />

to ICAO Contracting States and<br />

<strong>WMO</strong> Members before being submitted<br />

for adoption by the ICAO Council<br />

and approval by the <strong>WMO</strong> Executive<br />

Council.<br />

In accordance with the Working<br />

Arrangements between <strong>WMO</strong> and<br />

ICAO referred to earlier, through the<br />

<strong>WMO</strong> Commission for Aeronautical<br />

Meteorology (CAeM), responsible for<br />

implementing the <strong>WMO</strong> Aeronautical<br />

Meteorology Programme (AeMP),<br />

<strong>WMO</strong> is responsible for training<br />

meteorological personnel and for<br />

specifying the technical methods and<br />

practices to be used for the provision<br />

<strong>of</strong> meteorological service to international<br />

air navigation.<br />

The Commission’s session in 2002<br />

established eight expert teams under<br />

two broad open programme area<br />

groups (OPAG): OPAG-TREND, dealing<br />

essentially with training, improvements<br />

to forecasts, quality<br />

management and performance measurement;<br />

and OPAG-PROMET,<br />

responsible for customer focus, cost<br />

recovery, operational services and<br />

observations in the terminal area. The<br />

93


94<br />

Commission nominated two rapporteurs,<br />

one for the Aircraft<br />

Meteorological Data Relay (AMDAR)<br />

Programme and the other for aviation<br />

and the global atmospheric environment.<br />

In order to ensure that the needs<br />

<strong>of</strong> aviation users are fully addressed,<br />

representatives <strong>of</strong> ICAO, the International<br />

Air Transport Association<br />

(IATA) and the International Federation<br />

<strong>of</strong> Air Line Pilots Associations are<br />

invited to participate in meetings <strong>of</strong><br />

these CAeM structures. Furthermore,<br />

in 2004, <strong>WMO</strong> and IATA established<br />

focal points between the two<br />

Organizations to facilitate frequent<br />

contacts followed by similar arrangements<br />

with EUROCONTROL in 2005.<br />

This was prompted by the increased<br />

involvement <strong>of</strong> that Organization in<br />

activities related to the newly established<br />

Single European Sky (see box on<br />

previous page).<br />

In addition to the close cooperation<br />

between ICAO and <strong>WMO</strong> through<br />

CAeM, the <strong>WMO</strong> Commission for<br />

Basic Systems (CBS) is actively<br />

involved in ensuring the timely availability<br />

<strong>of</strong> basic meteorological data on<br />

which aviation weather forecasts are<br />

based. In this regard, the contribution<br />

<strong>of</strong> the AMDAR Programme to the<br />

availability <strong>of</strong> timely and accurate<br />

upper-air observations at various forecasting<br />

centres, including the two<br />

World Area Forecast Centres, has<br />

resulted in positive impacts on aviation<br />

forecast accuracy.<br />

Furthermore, CBS is also responsible<br />

for developing and updating the aeronautical<br />

meteorological codes used to<br />

disseminate aviation meteorological<br />

information. In this context, any new<br />

or updated aeronautical requirements<br />

included in ICAO Annex 3/<strong>WMO</strong><br />

Technical Regulations [C.3.1] are<br />

subsequently reflected in the <strong>WMO</strong><br />

Manual on Codes (<strong>WMO</strong>-No. 306,<br />

Volume I.1, Part A) following approval<br />

by CBS. ICAO is also interested in the<br />

The early detection <strong>of</strong> explosive volcano eruptions could serve as an early indication <strong>of</strong> the<br />

possible presence <strong>of</strong> airborne volcanic ash that is a serious threat to flight safety.<br />

emergency response activities <strong>of</strong><br />

CBS, in particular the Comprehensive<br />

Nuclear Test Ban Treaty Organization/<br />

<strong>WMO</strong> Emergency Response Activities.<br />

The potential usefulness <strong>of</strong><br />

monitoring information for the early<br />

detection <strong>of</strong> explosive volcano eruptions<br />

could serve as an early<br />

indication <strong>of</strong> the possible presence <strong>of</strong><br />

airborne volcanic ash that is a serious<br />

threat to flight safety.<br />

The contribution <strong>of</strong> the <strong>WMO</strong><br />

Commission for Instruments and<br />

Methods <strong>of</strong> Observations (CIMO) is<br />

essential for ensuring that the latest<br />

information concerning the capability<br />

<strong>of</strong> automatic meteorological observing<br />

systems are forwarded to ICAO<br />

for the development <strong>of</strong> future requirements.<br />

The Commission for<br />

Atmospheric Sciences (CAS) through<br />

its World Weather Research<br />

Programme is accelerating research<br />

on the prediction <strong>of</strong> high-impact<br />

weather and encouraging the utilization<br />

<strong>of</strong> advances in weather<br />

prediction systems to the benefit <strong>of</strong><br />

all <strong>WMO</strong> programmes including the<br />

AeMP.<br />

As indicated in the Working<br />

Arrangements between ICAO and<br />

<strong>WMO</strong> and stipulated in standard 2.1.5<br />

<strong>of</strong> Annex 3/Technical Regulations<br />

[C.3.1], <strong>WMO</strong> is responsible for the<br />

training and qualification <strong>of</strong> personnel<br />

providing meteorological service for<br />

international air navigation. In this<br />

regard, guidelines for the education<br />

and training <strong>of</strong> personnel in aeronautical<br />

<strong>meteorology</strong>, as well as relevant<br />

training material, are developed by the<br />

<strong>WMO</strong> Education and Training<br />

Programme (ETR) in close collaboration<br />

with relevant CAeM structures<br />

and active involvement <strong>of</strong> ICAO. This<br />

collaborative effort among ETR, CAeM<br />

and ICAO is expected to be actively<br />

pursued in the future.<br />

Key challenges to the meteorological<br />

community for ensuring the continued<br />

availability <strong>of</strong> good-quality, timely and<br />

cost-effective meteorological service<br />

to aviation include, among others, the


need for ensuring the sustainability <strong>of</strong><br />

the <strong>WMO</strong> World Weather Watch<br />

Programme that provides the basic<br />

data, data processing, transmission<br />

and forecasting on which meteorological<br />

service to aviation is based;<br />

increased automation <strong>of</strong> aerodrome<br />

meteorological observing systems;<br />

and improved terminal forecasts.<br />

Capacity building needs to be<br />

enhanced to ensure that aeronautical<br />

meteorologists, particularly those in<br />

developing countries, are abreast <strong>of</strong><br />

new technologies and adequately<br />

trained.<br />

Other challenges include increased<br />

reliance on the recovery <strong>of</strong> meteorological<br />

service costs from the aviation<br />

industry to fund aeronautical meteorological<br />

activities and meteorological<br />

infrastructure, particularly in view <strong>of</strong> a<br />

noted trend toward the disengagements<br />

<strong>of</strong> States from fully funding the<br />

traditional providers <strong>of</strong> service to aviation,<br />

namely National Meteorological<br />

Services (NMSs). This tendency has<br />

resulted in the increased use <strong>of</strong> alternative<br />

service delivery for aeronautical<br />

meteorological services, including the<br />

commercialization <strong>of</strong> some <strong>of</strong> these<br />

services and, increasingly, the establishment<br />

<strong>of</strong> fully autonomous national<br />

meteorological entities.<br />

Continued closer contacts with aviation<br />

users and their representative<br />

organizations, both at the global,<br />

regional and national levels, are particularly<br />

important to ensure that the<br />

services provided meet users’ needs<br />

and that users understand the existing<br />

capabilities and also the limitations <strong>of</strong><br />

such providers to deliver the required<br />

services to the aviation industry. In<br />

view <strong>of</strong> the financial difficulties being<br />

experienced by a number <strong>of</strong> airlines,<br />

due in part to increased expenditure<br />

on fuel, and other constraints such as<br />

more competition among air carriers,<br />

the airline industry is more than ever<br />

before insisting on the transparency <strong>of</strong><br />

charges paid to air navigation service<br />

providers, being in most cases the<br />

NMSs.<br />

The airlines have developed strict<br />

procedures for the use <strong>of</strong> meteorological<br />

information to improve safety and<br />

cost effectiveness. These procedures<br />

are based on a thorough evaluation <strong>of</strong><br />

the value and also the limitation <strong>of</strong><br />

meteorological observations and forecasts.<br />

With continuing aviation growth<br />

and demands for safety, efficiency and<br />

capacity, airlines and air-traffic<br />

management organizations are more<br />

than ever dependent on weather information<br />

for planning and safety. Future<br />

challenges will be for meteorological<br />

service providers to exploit the<br />

increasing availability <strong>of</strong> information<br />

and relevant detail in predictions from<br />

numerical models to improve the accuracy,<br />

content and relevance <strong>of</strong> the<br />

information provided to the aviation<br />

industry.<br />

Future perspectives<br />

The future requirements for aeronautical<br />

<strong>meteorology</strong> are expected to<br />

reflect technological developments<br />

which will allow more efficient methods<br />

<strong>of</strong> production and dissemination<br />

<strong>of</strong> meteorological information.<br />

The recent investments in research by<br />

the two World Area Forecast Centres<br />

are expected to result in their ability to<br />

produce gridded forecasts <strong>of</strong> turbu-<br />

lence, icing and convective clouds. It<br />

is conceivable that, in the future,<br />

these forecasts will replace the<br />

current significant weather information.<br />

It is expected that gridded<br />

forecasts will provide aviation users<br />

with more accurate information at the<br />

pre-flight planning stage and that the<br />

production <strong>of</strong> such forecasts will be<br />

more efficient and will, ultimately, be<br />

fully automated.<br />

One <strong>of</strong> the most important anticipated<br />

developments over the next few<br />

years will be the introduction <strong>of</strong><br />

table-driven codes (principally BUFR)<br />

for METAR/SPECI and TAF. The<br />

current communications infrastructure<br />

operated by ICAO is not able to<br />

cope with such digital codes. A careful<br />

planning process for this<br />

migration at the global, regional and<br />

national levels will, therefore, be<br />

necessary. The intention is that the<br />

migration will be completed globally<br />

by 2015.<br />

Requirements for meteorological<br />

information in support <strong>of</strong> the new<br />

ICAO air traffic management (ATM)<br />

concept are expected to be developed<br />

by a number <strong>of</strong> ICAO initiatives<br />

over the next few years. The<br />

purpose <strong>of</strong> the future ATM systems<br />

is the optimization <strong>of</strong> the use <strong>of</strong> the<br />

airspace. In this context, it is<br />

expected that new requirements will<br />

be formulated as far as meteorological<br />

information is concerned. The<br />

work in this area will involve close<br />

coordination with the relevant Air<br />

Traffic Services authorities and it is<br />

expected that specific proposals by<br />

ATM and meteorological experts will<br />

be developed by ICAO in close coordination<br />

with <strong>WMO</strong>. <br />

Maritime<br />

information<br />

for safety at<br />

sea<br />

Introduction<br />

By Henri Savina*<br />

Photo: CC Technolgies<br />

The safety <strong>of</strong> all kinds <strong>of</strong> vessels,<br />

from the biggest cargoes or tankers to<br />

the smallest recreational boats, are<br />

highly vulnerable to weather and<br />

oceanic natural hazards (strong winds,<br />

heavy seas, very poor visibility, etc.)<br />

and to other hazards that can sometimes<br />

be impacted by, or related to,<br />

meteorological or oceanographic conditions<br />

(e.g. the drift <strong>of</strong> dangerous<br />

submerged or floating objects, such<br />

as lost containers).<br />

Thus, to avoid loss <strong>of</strong> life and cargo<br />

(especially if the latter is <strong>of</strong> a hazardous<br />

nature), it is <strong>of</strong> primary importance to<br />

provide the appropriate—and evolving—Maritime<br />

Safety Information<br />

(MSI) to the large range <strong>of</strong> marine<br />

users. These include the industry<br />

waiting for detailed and focused<br />

safety information, reflecting increasing<br />

pressure on economic performance<br />

and the intention to operate in<br />

marginal conditions to gain advantage,<br />

to the smallest and less equipped<br />

crafts, that can also be <strong>of</strong> primary economic<br />

importance (fishing vessels in<br />

developing countries, for example).<br />

Maritime Safety Information (MSI)<br />

for mariners<br />

MSI provided to ships at sea can be<br />

divided into several types, including<br />

information related to search-andrescue<br />

operations, meteorological/<br />

oceanographic warnings and forecasts<br />

(generally provided by National Meteorological<br />

and Hydrological Services<br />

(NMHSs) or oceanographic centres)<br />

and navigational warnings (generally<br />

provided by National Hydrographic<br />

Offices).<br />

The dissemination <strong>of</strong> such information<br />

at sea may be done in various<br />

and multiple ways, such as VHF or<br />

HF radio, radio-telex, satellites, etc.,<br />

that can be fixed both at national or<br />

international level. It is <strong>of</strong> primary<br />

importance for mariners to know<br />

what information (content, broadcast<br />

scheduled time, dissemination channel)<br />

is available for their areas. Specialized<br />

agencies or companies issue<br />

and update specific <strong>of</strong>ficial publications,<br />

e.g. the Admiralty List <strong>of</strong> Radio<br />

Signals (UK Hydrographic Office) or<br />

Stations Radiométéorologiques<br />

(SH96 from the French Hydrographic<br />

Office) to be used on board ships.<br />

France and Chairman <strong>of</strong> the JCOMM Expert Team on Maritime Safety Services<br />

For meteorological/oceanographic<br />

MSI, this information comes from<br />

publication <strong>WMO</strong>-No. 99, Volume D.<br />

This is continuously updated, thanks<br />

to the contribution <strong>of</strong> all NMHS that<br />

are requested to provide to the<br />

<strong>WMO</strong> Secretariat (Ocean Affairs Division)<br />

all expected changes in their<br />

national dissemination system.<br />

Contemporary regulations and related<br />

conventions dealing with safety <strong>of</strong><br />

shipping, preservation <strong>of</strong> life, carriage<br />

<strong>of</strong> hazardous cargo and discharge <strong>of</strong><br />

ballast can be traced to the Safety <strong>of</strong><br />

Life at Sea Convention (SOLAS), which<br />

resulted from the Titanic disaster in<br />

1912. This Convention and the associated<br />

regulations and guidance materials<br />

for the provision <strong>of</strong> MSI are coordinated<br />

by the International Maritime<br />

Organization (IMO), the specialized<br />

Inmarsat<br />

Inmarsat provides telephony and<br />

data services to users worldwide,<br />

via special digital radios called<br />

"terminals". An Inmarsat terminal<br />

contacts the satellite and<br />

communicates to a ground<br />

station through the satellite. It<br />

provides reliable communications<br />

services to a wide range <strong>of</strong> users<br />

in remote regions or where there<br />

is no reliable terrestrial network.<br />

specific regulations for the provision<br />

<strong>of</strong> meteorological/oceanographic<br />

warnings and forecasts are coordinated<br />

by the <strong>WMO</strong>/IOC Joint Technical<br />

Commission for Oceanography<br />

and Marine Meteorology (JCOMM)<br />

and those for navigational warnings by<br />

the International Hydrographic Organization<br />

(IHO). Signatory States provide<br />

using satellite and terrestrial radiocommunications<br />

to ensure that wherever<br />

a ship is in distress, aid can be<br />

dispatched. This System regulates<br />

also the provision <strong>of</strong> MSI, both meteorological<br />

and navigational information,<br />

for SOLAS vessels on a global basis<br />

(Figure 1). All text-based information<br />

provided through the system is in<br />

English.<br />

The GMDSS was developed by IMO<br />

in close cooperation with the International<br />

Telecommunication Union,<br />

<strong>WMO</strong>, IHO and also COSPAS-<br />

SARSAT (an international satellite<br />

system coordinated by Canada,<br />

France, the Russian Federation and<br />

the USA).<br />

Since 1 February 1999, all SOLAS<br />

ships have had to comply with the<br />

GMDSS, and be fitted with all applicable<br />

satellite and radio-communication<br />

GMDSS equipment, according to the<br />

sea area(s) in which the ship operates,<br />

for sending and receiving distress<br />

alerts and MSI and for general com-<br />

munications. The GMDSS requirements<br />

are contained in Chapter IV <strong>of</strong><br />

SOLAS on radio-communications and<br />

were adopted in 1988. The GMDSS<br />

communications system under<br />

SOLAS complements the International<br />

Convention on Maritime Search<br />

and Rescue (1979), which was<br />

adopted in order to develop a global<br />

search-and-rescue plan.<br />

Specific equipment requirements for<br />

ships vary according to the sea area(s)<br />

in which the ship operates. The<br />

GMDSS combines various subsystems—which<br />

all have different limitations<br />

with respect to coverage—into<br />

one overall system, and the oceans<br />

are divided into four sea areas:<br />

Area A1—within range <strong>of</strong> VHF coast<br />

stations (about 20-30 nautical miles,<br />

i.e. 35-55 km);<br />

Area A2—beyond area A1, but<br />

within range <strong>of</strong> MF coastal stations<br />

(about 100 nautical miles, i.e.<br />

180 km);<br />

Area A3—beyond the first two<br />

areas, but within coverage <strong>of</strong> geostationary<br />

maritime communication<br />

satellites (in practice this means<br />

Inmarsat (see box on previous<br />

page). This covers the area between<br />

roughly 70°N and 70°S;<br />

Area A4—the remaining sea areas,<br />

generally polar regions. Geostationary<br />

satellites, which are positioned<br />

Figure 2 — NAVTEX receiver<br />

98<br />

above the Equator, cannot reach<br />

this far.<br />

Coastal vessels, for example, only<br />

have to carry minimal equipment if<br />

they do not operate beyond the range<br />

<strong>of</strong> shore-based VHF radio stations, but<br />

they may carry satellite equipment.<br />

Some coasts, however, do not have<br />

shore-based facilities so, although the<br />

ship is close to shore, the area counts<br />

as Area A2 or A3. Ships which do go<br />

beyond Sea Area A1 have to carry MF<br />

equipment as well as VHF—or<br />

Inmarsat satellite equipment. Ships<br />

which operate beyond MF range have<br />

to carry Inmarsat satellite equipment<br />

in addition to both VHF and MF. Ships<br />

which operate in area A4 have to carry<br />

HF, MF and VHF equipment.<br />

Under the GMDSS requirements, all<br />

ships concerned are required to be<br />

equipped with Inmarsat (Area A3)<br />

and/or international NAVTEX (see box<br />

on page 96) receivers (Area A2)—see<br />

Figure 2—to automatically receive<br />

MSI. Most fishing vessels and recreational<br />

boaters, which are non-SOLAS<br />

vessels (i.e. not required to participate<br />

in the GMDSS), are generally not<br />

equipped with such receivers, except<br />

in some parts <strong>of</strong> the world.<br />

GMDSS Inmarsat SafetyNET<br />

broadcast<br />

The International Mobile Satellite<br />

Organization (IMSO) (previously the<br />

International Maritime Satellite<br />

Organization) was established by<br />

IMO in 1976 to operate satellite<br />

maritime communication systems<br />

(and in particular the four Inmarsat<br />

geostationary satellites—see Figure<br />

3). It has become a privately owned<br />

company, whilst retaining its public<br />

sector obligations to the maritime<br />

distress and safety system.<br />

Inmarsat provides the space segment<br />

capacity to the GMDSS,<br />

Figure 3 — Inmarsat Satellites coverage<br />

(Copyright UK Hydrographic Office, issued from Admiralty List <strong>of</strong> Radio Signals. Vol. 5)<br />

including interaction with all<br />

Inmarsat LES (Land Earth Stations)<br />

operated by independent telecommunications<br />

corporations around<br />

the world. This space segment<br />

constellation provides a worldwide<br />

satellite coverage, except for the<br />

extreme polar regions.<br />

The Inmarsat SafetyNET Service is<br />

used by registered providers to<br />

broadcast MSI to mariners, according<br />

to a schedule table. Ships<br />

equipped with an Inmarsat C terminal,<br />

logged on one <strong>of</strong> the four<br />

satellites, will receive automatically<br />

the safety information for their<br />

location.<br />

International and national<br />

NAVTEX systems<br />

The transmission coverage/service<br />

area, defined in SOLAS, extends<br />

from the Fairway Buoy/Pilot Station<br />

to 250 nautical miles (i.e.<br />

about 450 km) from the NAVTEX<br />

station (transmitter) or to the<br />

range declared in the IMO GMDSS<br />

Master Plan. In particular, NAVTEX<br />

cannot be considered as a reliable<br />

system to receive meteorological<br />

information in port (other systems<br />

should be made available for endusers<br />

to obtain meteorological<br />

information in harbour).<br />

The international NAVTEX Service<br />

is the coordinated broadcast and<br />

automatic reception on the frequency<br />

518 kHz <strong>of</strong> MSI using the<br />

English language. As NAVTEX is a<br />

single frequency system, each<br />

NAVTEX station and content<br />

provider must take measures to<br />

prevent mutual interference with<br />

other stations. To avoid such<br />

mutual interference, each NAVTEX<br />

station is assigned specific time<br />

slots, which are 10 minutes in<br />

length every four hours (stations<br />

which share common time slots<br />

are arranged to be geographically


Figure 4 — Metareas (top); Navareas (bottom)<br />

distant). Responsibility for coordinating<br />

the establishment <strong>of</strong> the<br />

global NAVTEX service has been<br />

vested by IMO in its NAVTEX<br />

Coordinating Panel, that is in<br />

charge, in particular to assign the<br />

identification letter and the time<br />

slots allocated to each NAVTEX<br />

station.<br />

The two frequencies 490 kHz and<br />

4209.5 kHz are available to administrations<br />

for national NAVTEX broadcasts<br />

using their national language<br />

or English, particularly for non-<br />

SOLAS vessels. Although it is not<br />

part <strong>of</strong> GMDSS, it has also to be<br />

coordinated by the IMO NAVTEX<br />

Coordinating Panel.<br />

GMDSS coordinating mechanisms<br />

and <strong>WMO</strong> contribution<br />

For broadcast purposes, but also to<br />

ensure that services are available<br />

worldwide, the world’s oceans are<br />

divided into 16 areas, called either<br />

Metareas (for meteorological information)<br />

or Navareas (for navigational<br />

warnings) (see Figure 4).<br />

Each Metarea (Navarea) is under the<br />

responsibility <strong>of</strong> a National Meteorological<br />

Service named Issuing Service<br />

(or a National Hydrographic Office<br />

named Navarea Coordinator). The issuing<br />

Service (or Coordinator) is responsible<br />

for the provision (i.e. preparation<br />

and dissemination) <strong>of</strong> safety information<br />

on the Inmarsat SafetyNET broadcast<br />

and also for the coordination <strong>of</strong><br />

such information on the NAVTEX<br />

broadcast within its Metarea or<br />

Navarea. Other Services may provide<br />

some information for the Inmarsat<br />

SafetyNET broadcast, as Preparation<br />

Services: they are given responsibilities<br />

to prepare MSI for a specific part<br />

<strong>of</strong> the Metarea or in relation to a specific<br />

phenomenon, but the dissemination<br />

at sea is done by the Issuing Service.<br />

For example, South Africa is the<br />

Issuing Service for Metarea VII, but<br />

France (La Réunion) is responsible for<br />

preparing tropical cyclone warnings<br />

and also forecasts for some Antarctic<br />

subareas in the South-West Indian<br />

Ocean. Such products are sent to<br />

South Africa, in charge <strong>of</strong> the dissemination<br />

<strong>of</strong> all meteorological MSI by<br />

SafetyNET for Metarea VII.<br />

To participate as an information<br />

provider in the International Safety-<br />

NET Service, all Metarea Issuing Services<br />

and Navarea Coordinators<br />

must register with the IMO Safety-<br />

NET Panel to obtain a certificate <strong>of</strong><br />

Authorization. This certificate is<br />

requested to obtain permission from<br />

Inmarsat Land Earth Station Operators<br />

(LESOs) to broadcast on the<br />

99


100<br />

SafetyNET channel. Issuing Services<br />

or Coordinators are then able to disseminate<br />

through this channel MSI<br />

prepared for a whole Metarea, a circular<br />

or a rectangular area (Figures 5<br />

and 6).<br />

The <strong>WMO</strong> contribution to the<br />

GMDSS is coordinated by JCOMM,<br />

with the support <strong>of</strong> the meteorological<br />

Issuing Services, through two<br />

specific expert teams from the Services<br />

Programme Area :<br />

The Expert Team on Maritime<br />

Safety Services (ETMSS) for the<br />

dissemination <strong>of</strong> warnings and<br />

weather and sea bulletins according<br />

to a broadcast schedule.<br />

In particular, the ETMSS has a mandate<br />

to:<br />

• Monitor and review the operations<br />

<strong>of</strong> marine broadcast systems, not<br />

only for the GMDSS, but also for<br />

others related to vessels not covered<br />

by the SOLAS convention;<br />

• Monitor and review the technical<br />

and service quality standards for<br />

meteorological and oceanographic<br />

maritime safety information (particularly<br />

for the GMDSS); and<br />

• Implement appropriate actions to<br />

ensure that feedback from user<br />

communities is obtained through<br />

appropriate and organized channels<br />

and applied to improve the relevance,<br />

effectiveness and quality <strong>of</strong><br />

services;<br />

The ETMSS has to prepare and<br />

submit both regulatory (what Member<br />

States shall do) and guidance<br />

(what Member States should do)<br />

material regarding meteorological/<br />

oceanographic MSI;<br />

material is included either in the Manual<br />

on Marine Meteorological Services<br />

(<strong>WMO</strong>-No. 558) or in the Guide on<br />

(<strong>WMO</strong>-No. 471).<br />

The IHO contribution to the GMDSS,<br />

the World-Wide Navigational Warning<br />

Service (WWNWS), is coordinated by<br />

the IHO Commission for the Promulgation<br />

<strong>of</strong> Radio Navigational Warnings,<br />

with the support <strong>of</strong> Navarea<br />

coordinators.<br />

What about non-SOLAS vessels<br />

(fishing vessels, recreational<br />

boats …)?<br />

For non-SOLAS vessels, which may<br />

well be the most vulnerable and sen-<br />

sitive to weather and oceanic conditions,<br />

local laws and regulations and<br />

services available through national or<br />

nearby weather or ocean services<br />

agencies may or may not be sufficient.<br />

Problems in many areas <strong>of</strong> the<br />

developing world are likely to render<br />

the dissemination or even the production<br />

<strong>of</strong> MSI to mariners problematical.<br />

Some non-SOLAS vessels, like cruising<br />

boats, can be equipped with<br />

GMDSS receivers, but most are not.<br />

MSI prepared for large SOLAS ships<br />

are, however, generally not adapted<br />

to the vulnerability <strong>of</strong> small craft. If<br />

general regulations and guidelines for<br />

the provision <strong>of</strong> meteorological and<br />

oceanographic MSI in open seas, <strong>of</strong>fshore<br />

and coastal areas, and also in<br />

ports are included in the <strong>WMO</strong> Manual<br />

and Guide on Marine Meteorological<br />

Services, the services available at<br />

sea for non-SOLAS vessels depend<br />

on national capacities to produce<br />

appropriate MSI for the areas and the<br />

vessels concerned (warning criteria,<br />

for example, should be adapted to the<br />

vulnerability <strong>of</strong> targeted fleets) and to<br />

disseminate such safety information<br />

at sea through relevant channels,<br />

according to the telecommunication<br />

equipment on board those various<br />

ships (national administrations should<br />

also keep in mind that foreign non-<br />

SOLAS ships also need local safety<br />

information). Appropriate information<br />

and education materials should also<br />

be prepared and made available to<br />

mariners, to ensure that they are<br />

aware <strong>of</strong> the risks they may have to<br />

face, as far as possible, and know the<br />

ways to get appropriate warnings and<br />

forecasts for such risks.<br />

JCOMM, <strong>of</strong> course, has to play a key<br />

role in the provision <strong>of</strong> requested<br />

capacity-building for the provision <strong>of</strong><br />

MSI fitted for non-SOLAS vessels.<br />

The Commission will also encourage<br />

and promote national or regional projects<br />

for the implementation or<br />

upgrade <strong>of</strong> telecommunication networks<br />

and the equipment <strong>of</strong> fleets<br />

with appropriate MSI receivers.<br />

Key issues for the future<br />

The GMDSS has proved its efficiency<br />

and usefulness for mariners. Nevertheless,<br />

the requirements <strong>of</strong> maritime<br />

users, specifically the navies<br />

and global merchant fleets, have<br />

grown in response to change and<br />

innovation in ship design, the sharp<br />

increase in economic and competitive<br />

pressures and the increasing<br />

sophistication <strong>of</strong> shipboard environmental<br />

monitoring equipment and<br />

information and decision-support systems<br />

available on the bridge.<br />

Existing gaps, economic pressure,<br />

growing fleets <strong>of</strong> fishing vessels or<br />

recreational/cruising boats in some<br />

parts <strong>of</strong> the world are also an important<br />

factor to deal with. They are also<br />

a good stimulus to improve the issue<br />

101


102<br />

<strong>of</strong> natural disaster warnings for vessels<br />

which are not subject to the provisions<br />

<strong>of</strong> the SOLAS Convention (i.e.<br />

passenger and cargo ships engaged<br />

on domestic voyages, cargo ships<br />

engaged on international voyages<br />

whose gross tonnage is less than<br />

500, fishing vessels, ships <strong>of</strong> primitive<br />

build and pleasure yachts not engaged<br />

in trade).<br />

Some key issues for the future could<br />

be highlighted, in particular:<br />

Improve the dissemination <strong>of</strong> relevant<br />

safety information related to<br />

marine hazards in coastal and shelf<br />

areas, including tsunami-related<br />

information, for both SOLAS and<br />

non-SOLAS vessels. Regarding<br />

tsunami, the tragedy resulting from<br />

the Sumatran earthquake <strong>of</strong><br />

26 December 2004, has demonstrated,<br />

among other things, the<br />

overwhelming importance <strong>of</strong> having<br />

in place global, operational,<br />

robust and accurate tsunami warning<br />

services;<br />

MSI should also include, if available,<br />

tsunami-related information.<br />

The obvious reason is that all vessels<br />

in exposed areas (i.e. in ports,<br />

harbours or coastal areas) can be<br />

damaged or destroyed by tsunami<br />

and crews injured or lost. But,<br />

more generally, all potential channels<br />

to reach and alert threatened<br />

coastal communities and activities<br />

should be considered, at least as<br />

supplementary or interim ways,<br />

including those systems implemented<br />

for the provision <strong>of</strong> MSI to<br />

the maritime community;<br />

For example, the SafetyNET international<br />

service could be used, as<br />

proposed by IMO, to disseminate<br />

warnings to the relevant government<br />

<strong>of</strong>fices or local communities,<br />

either directly or indirectly, using<br />

SOLAS vessels as relays, espe-<br />

cially in coastal areas with nonexistent,<br />

inadequate or limited<br />

telecommunications infrastructure.<br />

Coordinating mechanisms have to<br />

be prepared in cooperation<br />

between IMO, IHO, <strong>WMO</strong> and the<br />

Intergovernmental Oceanographic<br />

Commission <strong>of</strong> UNESCO;<br />

Improve the content and/or dissemination<br />

<strong>of</strong> MSI, by integration<br />

<strong>of</strong> science and technology, especially<br />

regarding the sea state<br />

(description <strong>of</strong> complex and dangerous<br />

seas, study <strong>of</strong> the feasibility<br />

to provide risk information on freak<br />

waves) and sea ice. The coverage<br />

<strong>of</strong> polar regions should also be<br />

enhanced;<br />

Provide MSI in graphical form:<br />

clearly, the provision <strong>of</strong> MSI within<br />

GMDSS is constrained by format,<br />

technology and limits to additional<br />

utility/functionality, especially due<br />

to low bandwidth systems such as<br />

NAVTEX and even Inmarsat<br />

SafetyNET, that limit the volume<br />

<strong>of</strong> information that can be broadcast.<br />

Some specific guidelines and<br />

abbreviations for the preparation<br />

<strong>of</strong> NAVTEX meteorological MSI<br />

have been recently approved by<br />

JCOMM for this purpose. But one<br />

<strong>of</strong> the main challenges for the<br />

future is the dissemination <strong>of</strong><br />

GMDSS MSI in graphical or<br />

numerical form (that could be<br />

included, as overlays, in the electronic<br />

navigational charts now<br />

widely used by commercial ships),<br />

especially to replace the radio-facsimile<br />

broadcast;<br />

More generally, it is important for<br />

<strong>WMO</strong> to influence the regulators on<br />

the evolution <strong>of</strong> systems used to<br />

disseminate MSI, and to facilitate<br />

the access to such information on<br />

board ships or onshore. The<br />

JCOMM GMDSS Website<br />

(http://weather. gmdss.org (see Figure<br />

7), providing access in real-time<br />

to meteorological MSI prepared for<br />

SafetyNET dissemination, developed<br />

and maintained by Météo-<br />

France (<strong>WMO</strong> Bulletin 53 (2) (April<br />

2004)), should be considered as a<br />

contribution. This first version<br />

could be significantly enriched<br />

and improved by including additional<br />

products (graphics,


NAVTEX, ice information,...); integrating<br />

appropriate dynamic links<br />

with <strong>WMO</strong> associated documentation<br />

or other severe weatherrelated<br />

Websites; including navi-<br />

gational warning information in<br />

cooperation with IHO;<br />

Coordination mechanisms. As<br />

recommended by IMO, safety<br />

information provided to SOLAS<br />

vessels within the GMDSS shall<br />

be coordinated, in particular to<br />

provide non-conflicting warnings<br />

to mariners. This coordination, as<br />

described before, is under the<br />

responsibility <strong>of</strong> Navarea<br />

Coordinators and Metarea<br />

Issuing Services. There is still<br />

significant scope to improve this<br />

coordination for the provision <strong>of</strong><br />

meteorological/oceanographic<br />

MSI worldwide, to follow, for<br />

example, the virtue <strong>of</strong> the<br />

operational coordinating system<br />

put in place for the Baltic Sea.<br />

For European waters, the<br />

definition <strong>of</strong> coordinated<br />

common systems for the<br />

designation <strong>of</strong> marine forecast<br />

subareas to be used in<br />

meteorological warnings or<br />

scheduled bulletins (see <strong>WMO</strong><br />

Bulletin 53 (2)) has to be seen as<br />

a contribution to such a<br />

coordinating mechanism. But this<br />

is only a first step … <br />

By Zhai Panmao* and Yang Zhenbin*<br />

Background<br />

Climate elements such as sunlight,<br />

heat, water and wind are natural<br />

resources that can be used in many<br />

socio-economic sectors. For<br />

instance, when climate provides<br />

energy for crops, it can be considered<br />

an agrometeorological resource.<br />

Climate also can be a <strong>tourism</strong><br />

resource. Wind energy and solar radiation<br />

can be used as resources for<br />

power generation. They are impor-<br />

tant renewable and environmentally<br />

friendly energies in the modern<br />

world.<br />

Energy demand grows tremendously<br />

with rapid socio-economic development.<br />

It is predicted that, in 2020,<br />

energy consumption in China will<br />

have at least doubled that <strong>of</strong> 2002<br />

(http://www.cppcc.gov.cn/rmzxb/<br />

200601170078.htm). Such energy<br />

consumption is a challenge for conventional<br />

energy and also a heavy<br />

burden for the environment. Adjusting<br />

energy structure and increasing<br />

energy efficiency are the only<br />

choices for developing countries<br />

such as China.<br />

To cope with the energy issue, the<br />

Chinese Government has been taking<br />

measures to promote the development<br />

<strong>of</strong> renewable energy. For<br />

example, on 28 February 2005, the<br />

National People’s Congress <strong>of</strong> China<br />

passed the Chinese Renewable<br />

Energy Law. This law defines responsibilities<br />

and obligations <strong>of</strong> government,<br />

enterprises and users in the<br />

development and utilization <strong>of</strong><br />

renewable energy and provides a<br />

series <strong>of</strong> policies and measures,<br />

including a total quantity objective<br />

system, prices management system<br />

and special funds system. In force<br />

since 1 January 2006, it is foreseen<br />

that this law will greatly promote the<br />

development <strong>of</strong> renewable energy in<br />

China.<br />

Among all the renewable energies,<br />

wind power has developed most<br />

quickly. Figure 1 shows the growth in<br />

size <strong>of</strong> commercial wind turbines,<br />

which means the capacity <strong>of</strong> single<br />

wind turbine is becoming larger and<br />

larger. Economically, the cost <strong>of</strong> windpower<br />

generation and the price <strong>of</strong><br />

wind-power electricity worldwide has<br />

dropped rapidly in the last 10 years<br />

(EWEA et al., 2004). The table on the<br />

previous page gives the accumulative<br />

installed global capacity <strong>of</strong> wind power.<br />

It shows that the development <strong>of</strong> wind<br />

power has increased at the rate <strong>of</strong><br />

30.46 per cent annually over the last<br />

seven years.<br />

The Chinese Government has also paid<br />

attention to the technical development in<br />

wind energy. In recent years, wind<br />

energy has been developed with an<br />

increase <strong>of</strong> power generation from<br />

20 MW in 1992 to nearly 200 MW in<br />

2004 (see Figure 2). By the end <strong>of</strong> 2004,<br />

the total installed capacity <strong>of</strong> wind power<br />

in China reached 764 MW (see Figure 3)<br />

(EWEA et al., 2004). To further exploit<br />

wind energy, China formulated a Midlong<br />

Term Development Plan for windpower<br />

development in 2003: within<br />

about two years, China will conduct a<br />

wind-energy resource assessment,<br />

based on which, 20 wind-farm sites with<br />

a generation capacity <strong>of</strong> more than<br />

100 000 kW will be selected, nationwide.<br />

By 2020, China’s wind- power capacity<br />

will reach 30 000 MW (NDRC, 2005), i.e.<br />

a 30-fold increase over the next 14 years.<br />

Wind-energy development<br />

The China Meteorological Administration<br />

(CMA) is in charge <strong>of</strong> the management<br />

<strong>of</strong> climate resources, including<br />

wind energy. It has carried out many<br />

projects on assessing wind energy in<br />

recent decades.<br />

The CMA completed a first round <strong>of</strong><br />

wind-energy assessments in the<br />

1970s, based on wind data from some<br />

900 meteorological stations. The second<br />

round on general wind-resource<br />

investigation was finished in the<br />

1980s. The total potential <strong>of</strong> wind<br />

energy in China is 3 226 GW and the<br />

practical exploitable amount <strong>of</strong><br />

253 GW was proposed (Xue et al.,<br />

2002). It should be noted that this<br />

amount does not include <strong>of</strong>fshore<br />

potential, which is estimated to be<br />

approximately three times that <strong>of</strong> the<br />

rounds <strong>of</strong> wind-energy assessment<br />

are very general because <strong>of</strong> limited<br />

data. With the rapid development <strong>of</strong><br />

techniques for meteorological observation<br />

and data digitization, the CMA<br />

has accumulated wind data from more<br />

than 2 400 stations for a period <strong>of</strong><br />

more than 50 years.<br />

In order to provide a better basis for<br />

China’s ambitious wind-energy expansion<br />

plan, a more detailed windresource<br />

assessment project is being<br />

implemented. The third assessment is<br />

based mainly on wind data from those<br />

2 400 meteorological stations, supplemented<br />

weather stations, wind farms and<br />

wind towers, though it is still mainly<br />

based on measured wind speeds at a<br />

height <strong>of</strong> 10 m. Figure 4 shows the initial<br />

results.<br />

Additionally, the CMA is carrying out a<br />

series <strong>of</strong> pioneer studies on windenergy<br />

assessment, based on various<br />

techniques such as satellite remotesensing,<br />

geographical information systems<br />

and numerical simulations.<br />

Though the wind data collected are<br />

numerous, the distance between two<br />

observation sites ranges from about<br />

20 km in the east to 100 km in the<br />

west. Furthermore, many wind data<br />

are usually collected from sites near<br />

cities. The places with complex terrains<br />

with high wind-energy potential<br />

lack observations. With rapid socioeconomic<br />

development, the environment<br />

around the meteorological stations<br />

has changed greatly. It is<br />

necessary to assess the impact <strong>of</strong><br />

environmental change on wind-data<br />

homogeneity. One other limitation is<br />

that most <strong>of</strong> the historical wind data<br />

are observations at 10 m height,<br />

which does not meet the requirements<br />

for recently developed large<br />

wind turbines.<br />

Considering the above facts, the China<br />

Meteorological Administration is planning<br />

to establish an observation network,<br />

extend its services to meet<br />

national interests and identify the<br />

immediate needs <strong>of</strong> end-users. Relying<br />

on recent developments in meteorological<br />

science and technology and<br />

capacity building, the CMA is cooperating<br />

with relevant organizations to<br />

form a specialized team and take more<br />

active measures to promote the development<br />

<strong>of</strong> wind energy in China.<br />

Wind Energy Assessment Centre<br />

In order to enhance capacity-building<br />

in support <strong>of</strong> climate-related renew-<br />

able energy development, the CMA<br />

has brought together experts from<br />

various institutes and set up a specialized<br />

Wind Energy and Solar Energy<br />

Assessment Centre under the<br />

National Climate Centre. This Centre<br />

is leading CMA’s activities related to<br />

climate resources, with the focus on<br />

wind energy. Based on CMA’s institutional<br />

structure, this centre <strong>of</strong> excellence<br />

is responsible for facilitating<br />

downstream training in relevant disciplines,<br />

especially wind-energy assessment<br />

models and techniques.<br />

Future activities<br />

Developing manuals and guidelines<br />

In order to standardize the observation<br />

and assessment <strong>of</strong> wind-energy development,<br />

manuals and guidelines <strong>of</strong><br />

wind-energy measurement and assessment<br />

must be developed. In China,<br />

internationally produced manuals and<br />

guidelines for these purposes are<br />

reviewed on an ongoing basis and used<br />

for the development <strong>of</strong> similar manuals<br />

and guidelines for national needs.<br />

Models for mesoscale wind-energy<br />

mapping<br />

In view <strong>of</strong> the need for mapping the<br />

turbine height mesoscale wind climate,<br />

the CMA is enhancing research<br />

capacity in this field and is working<br />

with the Meteorological Service <strong>of</strong><br />

Canada on developing the WEST<br />

model (Treon and Petersen, 1989) in<br />

China. As soon as the wind-energy<br />

mapping system based on the numerical<br />

model has been built, a high-resolution<br />

wind atlas <strong>of</strong> China can be<br />

made. The CMA then intends to set<br />

up a national wind-energy resource<br />

database, which will be updated regularly<br />

and provide information for all<br />

users.<br />

S<strong>of</strong>tware for wind-farm<br />

micro-sitting<br />

The CMA is also working with the<br />

Danish Ministry <strong>of</strong> Foreign Affairs on<br />

introducing WAsP (Tron et al., 1989)<br />

(Wind Atlas Analysis and Application<br />

Program), a s<strong>of</strong>tware tool developed<br />

by the Danish Risø national labora-<br />

Figure 4 — The distribution <strong>of</strong> wind-power in China (initial result <strong>of</strong> the new project)


tory for wind-farm micro-siting using<br />

a linear wind-farm diagnosis model.<br />

Our experience <strong>of</strong> using WAsP for<br />

micro-siting in complex terrain suggests<br />

that the uncertainty in assessing<br />

annual production <strong>of</strong> the wind<br />

farm is too large. Another plan is for<br />

the CMA to develop wind-farm<br />

micro-siting s<strong>of</strong>tware based on an<br />

aerodynamical model to meet specific<br />

requirements.<br />

Offshore wind energy<br />

The Chinese Government also plans to<br />

exploit <strong>of</strong>fshore wind energy. This will<br />

necessitate an investigation <strong>of</strong><br />

resources, which will provide the primary<br />

scientific foundation for design<br />

and construction.<br />

Climate change and wind energy<br />

Recent studies have indicated that<br />

climate change impacts most socioeconomic<br />

activities. In the global<br />

warming scenario, wind speed can<br />

also change. There is as yet, however,<br />

no systematic study <strong>of</strong> the effect <strong>of</strong><br />

climate change on wind-energy<br />

resources in China.<br />

As wind energy develops, more and<br />

more wind farms will be built. Considering<br />

that the lifetime <strong>of</strong> a wind farm<br />

is 15-20 years, the climate-change<br />

issue must be considered at the feasibility<br />

study stage. Moreover, fossilfuel<br />

consumption will be reduced and<br />

will thus slow down the rate <strong>of</strong> climate<br />

warming.<br />

The CMA plans to conduct research<br />

to assess the relationship between climate<br />

change and wind energy.<br />

Wind-energy prediction<br />

Wind-energy prediction is an effective<br />

way <strong>of</strong> providing wind-farm production<br />

information for the grid-control <strong>of</strong><br />

electricity. Some countries have<br />

already set up a system to provide a<br />

prediction service for wind farms. The<br />

CMA also has a plan to construct a<br />

prediction system deriving from the<br />

existing weather forecast system and<br />

high-resolution model.<br />

Assessing meteorological<br />

disasters<br />

Extreme weather conditions are a<br />

danger for the safety <strong>of</strong> wind-farm<br />

operations. For instance, concerning<br />

the -turbines, a typhoon can easily<br />

destroy them; iced blades can result<br />

in their underperformance; and<br />

extremely cold temperatures can<br />

cause them to shut down. An<br />

assessment <strong>of</strong> meteorological disasters<br />

is therefore important for establishing<br />

and operating a wind farm and<br />

the CMA is planning work in this<br />

field.<br />

Offshore<br />

ocean<br />

information<br />

for safety<br />

Introduction<br />

By Johannes Guddal*<br />

Design <strong>of</strong> safe and economic <strong>of</strong>fshore<br />

structures (construction and<br />

ships) has become an <strong>of</strong>fshore industry<br />

requirement. Knowledge <strong>of</strong> wave<br />

information, in particular extreme<br />

events and related wave-structure<br />

interactions, is a requisite. A stochastic<br />

analysis <strong>of</strong> the long-term<br />

time-series <strong>of</strong> wave parameters, such<br />

as significant wave height, is typically<br />

used to plan engineering applications;<br />

and nowcast and forecast information<br />

is applied for operations at sea.<br />

Nowadays, this kind <strong>of</strong> approach is<br />

insufficient, not only because <strong>of</strong> the<br />

continuous expansion <strong>of</strong> <strong>of</strong>fshore<br />

industry to deeper waters that creates<br />

new challenges to the ocean<br />

research community, but also<br />

because <strong>of</strong> the increase in extreme<br />

events which exceed wave-design<br />

criteria. Dedicated methods and<br />

numerical modelling are required in<br />

order to better characterize the wave<br />

kinematics and dynamics and their<br />

effects on structures.<br />

Mitigating extreme conditions<br />

at sea<br />

Offshore structures operate typically<br />

in fixed locations and are exposed to<br />

maritime multi-hazards. Consequently,<br />

a well-developed plan <strong>of</strong><br />

action, based on design preparedness<br />

and operations planning, is used<br />

Design preparedness<br />

Location and exposure<br />

When a potential oil- or gasexploration<br />

position has been identified,<br />

preparation <strong>of</strong> the design criteria<br />

starts. Environmental loads<br />

are the basis for the <strong>of</strong>fshore platform<br />

design that is supported by<br />

meteorological and oceanographic<br />

climatological datasets.<br />

Wave data (measurements and<br />

numerical modelling)<br />

In the last two decades, oil companies<br />

have collected a large amount<br />

<strong>of</strong> wave data in different parts <strong>of</strong><br />

the world for their own use. Even<br />

though long-time datasets exist<br />

worldwide, there is still a need to<br />

make use <strong>of</strong> both measurements<br />

and model data (quantifying their<br />

uncertainties) for some places<br />

where measured data series are<br />

too short or non-existent.<br />

Recently, these series have been


complemented by satellite data,<br />

which supplement in situ measurements.<br />

Extrapolation to extremes<br />

Generally, <strong>of</strong>fshore structures are<br />

designed for a specific place and<br />

for the 100-year wave (ultimate<br />

limit state (ULS)) that correspond to<br />

the probability <strong>of</strong> failure <strong>of</strong><br />

1/(365 days x 100 years x 8 interval<br />

<strong>of</strong> 3 hours in a day) in a random<br />

three-hour sea state. Statistical<br />

methods are used to estimate the<br />

100-year wave value.<br />

Operations planning<br />

Long lead time<br />

Major <strong>of</strong>fshore operations, such as<br />

the towing and deployment <strong>of</strong> large<br />

constructions, are scheduled for<br />

days with favourable weather and<br />

sea-state conditions. According to<br />

these statistics, preliminary timing<br />

is set for the operation and the<br />

logistic preparations are organized<br />

accordingly.<br />

Short lead time<br />

Major sensitive operations like towing,<br />

pipe-laying and construction<br />

deployments are supported by<br />

nowcast and forecast services<br />

specifying sea-state and weather<br />

progress.<br />

developed from the occurrence <strong>of</strong> a major marginal incident and is now a composition <strong>of</strong><br />

various elements, all in a mutual understanding between <strong>of</strong>fshore decision-makers and<br />

forecast providers.<br />

All safety-related services for the<br />

industry require the combination <strong>of</strong><br />

human expertise and advanced<br />

numerical modelling. Human expertise<br />

is required due to the selection<br />

<strong>of</strong> the complementary sea-state<br />

monitoring technology, whether in<br />

situ or by remote-sensing. Also, in<br />

the event <strong>of</strong> damage or accidents, a<br />

post-analysis will be required involving<br />

high-level expertise.<br />

Coherence in design and<br />

operation<br />

The requirement <strong>of</strong> the <strong>of</strong>fshore<br />

industry to provide sea-state information<br />

constitutes a great challenge<br />

to service providers, both in<br />

terms <strong>of</strong> serving designers’ needs<br />

and in terms <strong>of</strong> serving operations.<br />

It may be instructive to see the<br />

commonalities <strong>of</strong> the two modes <strong>of</strong><br />

operation.<br />

When marine construction is<br />

designed and subsequently put into<br />

operation, there should be a complementary<br />

link between how meteorological<br />

and oceanographic data have<br />

been utilized; at the design stage,<br />

later in regular forecasting, and at<br />

the time <strong>of</strong> the eventual damage<br />

assessment. This is not always the<br />

case, since there are different and<br />

competing providers; and tools and<br />

science used in the applications<br />

change over time. The global baselines<br />

are the <strong>WMO</strong> wave database<br />

applied in traditional marine design;<br />

and the <strong>WMO</strong> contribution to the<br />

International Maritime Organization’s<br />

programme, the Global Maritime<br />

Distress and Safety System<br />

(GMDSS).<br />

The dedicated, safety-related services,<br />

extending from these baselines,<br />

require constant revision <strong>of</strong> the<br />

system, close communication with<br />

operation decision-makers, and a<br />

nucleus <strong>of</strong> scientific experts on marginal<br />

sea-state characteristics.<br />

The <strong>of</strong>fshore industry has been<br />

advised to fill some gaps in the present-day<br />

delivery <strong>of</strong> safety-related<br />

services to their operations. These<br />

gaps are;


• Need for better understanding <strong>of</strong> the<br />

“physics <strong>of</strong> extremes”<br />

• The feasibility/sustainability <strong>of</strong> in situ<br />

and remote-sensing monitoring<br />

systems<br />

• Modes <strong>of</strong> interactions between decision-makers<br />

and warning providers<br />

• Needs for revision <strong>of</strong> existing and<br />

multiple operational thresholds<br />

Role <strong>of</strong> the <strong>WMO</strong>/IOC Joint<br />

JCOMM’s Members in 123 countries<br />

hold the technical, scientific,<br />

and operational expertise that is necessary<br />

for serving the <strong>of</strong>fshore<br />

industry. JCOMM coordinates inter-<br />

Member functions, such as oceanobservation<br />

programmes, data management<br />

and exchange, service<br />

developments and capacity-building.<br />

Already at this early stage in<br />

JCOMM operations, comprehensive<br />

data- and modelling-expertise<br />

resources are available for the international<br />

community. A two-way<br />

cooperation and communication with<br />

industry was already established in<br />

the 1990s, and will be enhanced in<br />

the years to come. <br />

Indian Ocean*<br />

The project summarized<br />

The Western Indian Ocean Marine<br />

<strong>Applications</strong> Project (WIOMAP) aims<br />

at contributing to the sustainable management<br />

and optimum exploitation <strong>of</strong><br />

marine and land resources through<br />

more efficient short-, medium- and<br />

long-term planning. This will be<br />

achieved through improved ocean predictions<br />

and weather and climate forecasts,<br />

based on the enhancement <strong>of</strong><br />

coastal and open-ocean observing<br />

systems. It will focus on capacitybuilding<br />

<strong>of</strong> national institutions to<br />

enable them to take advantage <strong>of</strong><br />

modern technology in ocean monitor-<br />

* A contribution from the <strong>WMO</strong> Secretariat<br />

ing and new developments in ocean<br />

modelling.<br />

WIOMAP will ensure that ocean<br />

observations in the western Indian<br />

Ocean, in support <strong>of</strong> the Global Ocean<br />

Observing System and the Global Climate<br />

Observing System, are sustained<br />

and utilized for research and<br />

operational applications. The products<br />

generated by Specialized Regional<br />

Marine Application Centres and disseminated<br />

through an enhanced communication<br />

system will contribute<br />

substantially to improve the welfare <strong>of</strong><br />

populations in the region in terms <strong>of</strong><br />

poverty alleviation and food security.<br />

Background<br />

Countries <strong>of</strong> the western Indian<br />

Ocean (WIO) region are mostly developing<br />

countries, where the main concerns<br />

are food and housing security.<br />

The potential exists to increase the<br />

exploitation <strong>of</strong> marine resources in a<br />

sustainable manner. Among these are<br />

fisheries, ocean energy, mineral<br />

resources and coastal <strong>tourism</strong>. As the<br />

population increases and the shortage<br />

<strong>of</strong> land for cultivation becomes more<br />

acute, marine resources will be<br />

increasingly used as a food supply.<br />

WIO countries have additional responsibilities<br />

with the adoption <strong>of</strong> the<br />

United Nation Convention on the Law<br />

<strong>of</strong> the Sea (UNCLOS), which obliges<br />

coastal and island States to protect<br />

and manage their marine resources<br />

within their 320-km economic zones.<br />

Ocean circulation and coastal<br />

processes in the region are unique. In<br />

the northern part, there is an annual<br />

reversal <strong>of</strong> wind direction and ocean<br />

current. The Somali current <strong>of</strong>f Somalia,<br />

which develops during the northern<br />

hemisphere summer, regulates<br />

the Asian subcontinent climate and,<br />

through upwelling, enhances living<br />

marine resources. The Agulhas cur-<br />

The WIOMAP project proposal<br />

rent <strong>of</strong>f south-eastern South Africa, is<br />

an important feature <strong>of</strong> the ocean circulation.<br />

The Mascarenes Plateau<br />

between Mauritius and Seychelles is<br />

unique. It is the only continental shelf<br />

in the world which is detached from<br />

the mainland and it influences significantly<br />

ocean processes in the region.<br />

For these reasons, marine scientists<br />

consider the region as a natural laboratory<br />

for research purposes.<br />

The tropical region <strong>of</strong> the WIO lies in<br />

the tropical cyclone belt, which<br />

derives its energy from the ocean. On<br />

average, 10 devastating tropical<br />

cyclones affect the area from 5–25°S,<br />

40–80°E each year, mainly from


December to March. These weather<br />

systems inevitably cause loss <strong>of</strong> life<br />

and damage to coastal property,<br />

potentially crippling the economy <strong>of</strong><br />

the countries. Flooding in Madagascar,<br />

Mozambique, South Africa and<br />

Zimbabwe, as a result <strong>of</strong> cyclones<br />

Connie, Eline, Gloria and Hudah, from<br />

January to April 2000, caused an estimated<br />

1.17 billion euros in property<br />

and infrastructure losses and more<br />

than 1 000 deaths. This example provides<br />

an illustration <strong>of</strong> the vulnerability<br />

<strong>of</strong> WIO countries to severe weather.<br />

By their very nature, tropical cyclones<br />

do not recognize any geographical<br />

boundaries. Hence, countries should<br />

establish, on a regional basis, the necessary<br />

infrastructure and human<br />

resources to meet the growing<br />

demand for marine data and services<br />

from a wide spectrum <strong>of</strong> users in an<br />

efficient and cost-effective fashion.<br />

Project objectives<br />

The overall development objective <strong>of</strong><br />

the project is to contribute to the<br />

conservation and sustainable use <strong>of</strong><br />

marine resources in the region and<br />

to foster environmental protection<br />

and socio-economic development<br />

through improved application <strong>of</strong><br />

marine data and products. Improved<br />

understanding <strong>of</strong> biophysical<br />

processes will enable long-term<br />

development objectives to be met.<br />

By the end <strong>of</strong> the project, it is<br />

expected that the WIO region will<br />

acquire sufficient capability to<br />

enable regional modelling and participation<br />

with more advanced marine<br />

institutions. Additional marine data,<br />

both at the surface and subsurface,<br />

will be available in real-time as valuable<br />

input to predictive models to<br />

improve the analysis <strong>of</strong> tropical<br />

cyclones, for example, and the<br />

effective and efficient exploitation <strong>of</strong><br />

regional marine resources.<br />

Through specialized courses and<br />

workshops, the National Meteorological<br />

Services (NMSs) and other<br />

relevant institutions within the<br />

region will acquire improved pr<strong>of</strong>essional<br />

capabilities.<br />

The value <strong>of</strong> regional cooperation<br />

through sharing and co-sponsoring<br />

sophisticated equipment and the<br />

establishment <strong>of</strong> regional centres in<br />

support <strong>of</strong> marine meteorological<br />

and oceanographic services has<br />

long been recognized. A first<br />

attempt was made in the Gulf<br />

region with the cooperative development<br />

<strong>of</strong> a Regional Marine Meteorology<br />

Project in the early 1980s,<br />

involving all the seven countries <strong>of</strong><br />

the region. Further to the successful<br />

development <strong>of</strong> the South-East<br />

Asian subregional project (South-<br />

East Asian Centre for Atmospheric<br />

and Marine Prediction (SEACAMP),<br />

the former <strong>WMO</strong> Commission for<br />

Marine Meteorology (11th session,<br />

Lisbon, Portugal, April 1993) recommended<br />

that studies be undertaken<br />

on the possibility <strong>of</strong> developing similar<br />

projects in other geographical<br />

areas, initially in East and West<br />

A First <strong>WMO</strong>/Intergovernmental<br />

(WIOMAP) was held in Mauritius in<br />

May 1997 with the participation <strong>of</strong><br />

National Meteorological Services and<br />

oceanographic institutions in the<br />

region. The main conclusions were<br />

the need for:<br />

A regional project as a contribution<br />

to the Global Ocean Observing<br />

System (GOOS), which was called<br />

for by Agenda 21 <strong>of</strong> the United<br />

Nations Conference on Environment<br />

and Development (UNCED,<br />

Rio de Janeiro, 1992), to enhance<br />

the provision <strong>of</strong> marine services<br />

Institutional framework<br />

All countries in the western Indian<br />

Ocean currently have NMSs which provide<br />

weather and sea forecasts for the<br />

general public and marine communities,<br />

as well as advisories and services<br />

in various socio-economic sectors,<br />

including coastal and marine resources,<br />

agriculture, water resources, health,<br />

energy, <strong>transport</strong> and industry. Kenya,<br />

Mauritius, Réunion and South Africa<br />

have established Port Meteorological<br />

Offices to provide dedicated services<br />

to shipping.<br />

Oceanographic activities, though scattered<br />

through various institutions, are<br />

being coordinated at national level<br />

through National Oceanographic Committees.<br />

Mauritius and South Africa<br />

have established National GOOS<br />

Coordination Committees.<br />

Capacity-building, with emphasis on a<br />

postgraduate course and short training<br />

courses, will be one <strong>of</strong> the major components<br />

<strong>of</strong> the project proposal. Wellestablished<br />

training institutions <strong>of</strong>fer<br />

courses in different fields <strong>of</strong> <strong>meteorology</strong><br />

and oceanography. These could<br />

be further strengthened to play a<br />

major role in the implementation <strong>of</strong><br />

the training component <strong>of</strong> WIOMAP.<br />

The establishment <strong>of</strong> specialized<br />

regional modelling and product preparation<br />

centres has been proposed in various<br />

forums to optimize human and<br />

infrastructural resources. Several<br />

meteorological and oceanographic institutions<br />

in the region have the capability<br />

to host such centres. They will be<br />

upgraded and provided with external<br />

assistance to reach the appropriate level<br />

in order to take up this responsibility.<br />

Problems to be addressed<br />

The Indian Ocean, in particular the<br />

western part, is poorly sampled. It is<br />

WIOMAP and the Global Ocean<br />

Observing System<br />

WIOMAP was discussed in depth<br />

at the first conference <strong>of</strong> the<br />

Indian Ocean Global Ocean<br />

Observing System (IOGOOS-I,<br />

Mauritius, November 2002) and<br />

valuable feedback obtained to<br />

improve the proposals.<br />

WIOMAP will also contribute to<br />

the activities <strong>of</strong> the other GOOS<br />

alliances in the region: GOOS<br />

Africa, Western Australia GOOS<br />

(WAGOOS) and South-East Asia<br />

GOOS (SEAGOOS) in enhancing<br />

ocean observations and improving<br />

ocean services in the Indian<br />

Ocean.<br />

Support for its development was<br />

further reiterated during the<br />

second conference <strong>of</strong> IOGOOS<br />

(IOGOOS-II, Sri Lanka, April<br />

2004).<br />

now widely recognized that the Pacific,<br />

Atlantic and Indian Oceans are linked by<br />

teleconnections and any abnormal<br />

weather and climate events in one <strong>of</strong><br />

them affect the other two. Efforts to<br />

build up a comprehensive ocean observation<br />

network have up to now concentrated<br />

on the Pacific and Atlantic<br />

Oceans. Various forums have underscored<br />

the importance <strong>of</strong> shifting the<br />

effort to the Indian Ocean to complete<br />

the global network and thus obtain a<br />

global picture <strong>of</strong> atmospheric and<br />

ocean general circulation. This is essential<br />

to understand weather and climate<br />

variability and trends on different timescales<br />

at the local, regional and global<br />

levels. This is a prerequisite to improve<br />

weather and climate forecast.<br />

With global warming, changes in<br />

atmospheric and oceanographic<br />

parameters are expected to vary<br />

from region to region. A close and<br />

long-term time-scale monitoring <strong>of</strong><br />

the WIO will be required to identify<br />

regional changes as soon as they<br />

occur so that proactive measures<br />

may be taken to address the socioeconomic<br />

issues related to climate<br />

change and sea-level rise.<br />

The availability <strong>of</strong> a long-term series<br />

<strong>of</strong> meteorological and oceanographic<br />

data and products will address, in<br />

particular, the following issues:<br />

More efficient exploration and<br />

exploitation and sounder management<br />

<strong>of</strong> the abundant WIO marine<br />

resources, through detailed knowledge<br />

<strong>of</strong> the ocean such as seasurface<br />

and subsurface temperature<br />

distribution and more reliable<br />

and timely weather forecasts;<br />

Coastal erosion and marine pollution<br />

monitoring through more<br />

accurate and timely prediction <strong>of</strong><br />

waves, storm surges and tidal<br />

conditions;<br />

Better level <strong>of</strong> preparedness,<br />

effectiveness and efficiency <strong>of</strong><br />

early warning systems in case <strong>of</strong><br />

natural disasters such as cyclones,<br />

floods, droughts and heavy seas;<br />

Better output from ocean and general<br />

circulation models for predictive<br />

purposes;<br />

More in-depth knowledge <strong>of</strong> the<br />

relatively recent Indian Ocean<br />

dipole concept. This is a strong<br />

ocean-atmosphere coupled system<br />

that is linked to the El Niño-<br />

Southern Oscillation phenomenon<br />

and to monsoon variability. It has<br />

been found to be strongly tied to<br />

annual cycles and climate variability,<br />

especially with respect to<br />

“short rain” episodes in East<br />

Africa;


Better assessment <strong>of</strong> ocean<br />

renewable sources <strong>of</strong> energy<br />

(waves, tides, ocean thermal<br />

energy conversion optimal exploration<br />

and exploitation.<br />

In particular, WIOMAP will address<br />

the following shortcomings and deficiencies<br />

in the:<br />

Level <strong>of</strong> expertise in marine <strong>meteorology</strong><br />

and oceanography;<br />

Marine observing network;<br />

Communication facilities for<br />

smooth exchange <strong>of</strong> data and products;<br />

and<br />

Regional modelling for generating<br />

products <strong>of</strong> practical application.<br />

Expected outcomes<br />

By the end <strong>of</strong> the project, it is<br />

expected that National Meteorological<br />

Services and oceanographic institutions<br />

in the region will have<br />

acquired:<br />

Improved pr<strong>of</strong>essional capabilities<br />

necessary for the further development<br />

and provision <strong>of</strong> marine products<br />

and information;<br />

Additional marine data, both at the<br />

surface and subsurface as valuable<br />

input to regional and global models<br />

for the improvement <strong>of</strong> products;<br />

An improved modern communication<br />

system for the collection and<br />

dissemination <strong>of</strong> marine data and<br />

products in a reliable and timely<br />

manner;<br />

New regional marine products for<br />

national adaptation which will be<br />

used as inputs in various socio-economic<br />

sectors to enhance efficiency<br />

and production; and<br />

As populations<br />

increase in the<br />

western Indian<br />

Ocean region and<br />

the shortage <strong>of</strong><br />

land for cultivation<br />

becomes<br />

more acute,<br />

marine resources<br />

will be increasingly<br />

used as a<br />

food supply.<br />

Enhanced capabilities for countries’<br />

more active participation in<br />

national, regional and international<br />

marine programmes, which<br />

is essential for their success and<br />

timely completion.<br />

It is expected also that the level<br />

reached by countries and potential<br />

regional marine centres, in terms <strong>of</strong><br />

equipment and trained manpower,<br />

will be high enough to ensure selfsustainability.<br />

Beneficiaries<br />

At the national level, the main target<br />

groups and activities to benefit<br />

directly from the project through<br />

improved marine information and<br />

services are:<br />

Policy- and decision-makers in<br />

marine environmental management;<br />

Government institutions and<br />

organisations involved in maritime<br />

activities such as environmental<br />

departments, shipping,<br />

port authorities, oil companies<br />

and ship routeing;<br />

Meteorological Services for<br />

improved weather forecasts and<br />

warnings at sea to save life and<br />

property;<br />

Institutions involved in regional climate<br />

forecasting to improve local<br />

and regional climate forecasts for<br />

early warning systems—for<br />

cyclones, drought and flooding—for<br />

better agricultural and waterresources<br />

planning and management,<br />

and hence food security;<br />

Oceanographic institutions to promote<br />

the development <strong>of</strong> operational<br />

oceanography;<br />

Oceanographers for research work;<br />

Coastal development and management<br />

for optimum exploration and<br />

exploitation <strong>of</strong> resources, including<br />

ocean energy, <strong>tourism</strong>, sand mining<br />

and addressing the problem <strong>of</strong><br />

coastal erosion;<br />

Fisheries management to rationalize<br />

activities and minimize the depletion<br />

<strong>of</strong> stocks; and<br />

Marine pollution monitoring and protection<br />

<strong>of</strong> the marine environment. <br />

Making<br />

climate serve<br />

the people<br />

Michael H. Glantz*<br />

Fire and water are good servants<br />

but bad masters<br />

(Aesop, 620–565 BC)<br />

It is clear to me that Aesop’s quote<br />

refers indirectly to the climate system,<br />

whence the water comes. What<br />

I am implying here is that climate,<br />

too, can be a good servant but a bad<br />

master. The reality is that, from an<br />

anthropocentric perspective, before<br />

humans inhabited planet Earth, climate<br />

systems from local to global<br />

were neutral.<br />

* Senior Scientist, National Center for<br />

Atmospheric Research Boulder, Colorado,<br />

USA<br />

Again from an anthropocentric perspective,<br />

with the advent <strong>of</strong> humans<br />

and human settlements, climate was<br />

no longer neutral, in the sense that it<br />

interacted with human settlements<br />

and human activities for good and for<br />

ill. Little was understood in earlier<br />

times about the climate system and,<br />

as a result, there was little that people<br />

could do to affect natural variability<br />

and change. While some settlements<br />

prospered using regional climate conditions<br />

to their advantage, others suffered<br />

from the apparently harsh<br />

regional climates. Areas with<br />

favourable climate conditions (i.e.<br />

favourable for agriculture and livestock)<br />

and with adequate streamflow<br />

originating from distant sources, fared<br />

well. Their land (and favourable climate)<br />

may have been coveted by<br />

neighbouring peoples. From a climate<br />

perspective, those less fortunate<br />

areas suffered relatively more frequently<br />

from the seasonal-to-interannual<br />

variations <strong>of</strong> climate, as well as<br />

from prolonged droughts, recurrent<br />

floods, frequent fires or frosts, etc.<br />

If Aesop were alive today, I think that<br />

he would have added climate to his<br />

comment above.<br />

Fire, water and climate are good<br />

servants but bad masters<br />

(Glantz, 2005)<br />

By the end <strong>of</strong> the 20th century, hundreds<br />

if not thousands <strong>of</strong> articles,<br />

books and reports had been written<br />

about the importance and value <strong>of</strong><br />

using weather and climate information<br />

in decision-making processes. Many<br />

benefits <strong>of</strong> climate information (or better<br />

yet, climate knowledge) are obvious:<br />

improved meteorological forecasts,<br />

climatological time series (i.e.<br />

climate history), monitoring <strong>of</strong> climateand<br />

weather-related hazards, climateimpact<br />

assessments and research<br />

findings, advances in global climate<br />

This article is drawn from a lecture<br />

presented by the author to the<br />

57th session <strong>of</strong> the <strong>WMO</strong><br />

Executive Council (June, 2005).<br />

modelling, etc. These are the usual<br />

kinds <strong>of</strong> benefits that people point to<br />

when highlighting the value <strong>of</strong> climate<br />

knowledge to a given society or to<br />

policy-makers whose financial and<br />

moral support they are seeking.<br />

Here, however, I want to try to<br />

address questions about climate as a<br />

resource in a different way. How<br />

might we make the climate systems<br />

from local to global more <strong>of</strong> a servant<br />

<strong>of</strong> the people and less its whimsical<br />

and unpredictable master? I have the<br />

view that climate is a natural (and neutral)<br />

resource, albeit a varying one, surrounded<br />

by many uncertainties. It merits<br />

respect and necessitates<br />

“appropriate” interactions by societies<br />

that operate in very different ways and<br />

have different needs from climate.<br />

This means that climate-societyenvironment<br />

interactions are <strong>of</strong>ten<br />

location-specific, though generalizations<br />

can be drawn from case-studies.<br />

Today there is an amazing amount <strong>of</strong><br />

interest in a wide range <strong>of</strong> climate and<br />

climate-related topics. A recent university<br />

graduate would probably not<br />

know that, just a decade or two ago,<br />

climate was not a major concern to<br />

the media or to policy-makers. As was<br />

usually the case then, the media<br />

would report on a climate-related<br />

issue if it involved death, destruction<br />

or imminent threat to a society, such<br />

as a hurricane or typhoon.<br />

For example, just two decades ago, a<br />

major drought, widespread food shortage<br />

and famine developed in several<br />

countries in sub-Saharan Africa. Yet,<br />

despite widespread death <strong>of</strong> humans<br />

and livestock and destruction <strong>of</strong> the


environment, the popular media failed<br />

to recognize drought as one <strong>of</strong><br />

Africa’s “woes.”<br />

In the 16 January 1984 issue <strong>of</strong> TIME,<br />

only two sentences in the entire magazine<br />

referred to the impacts <strong>of</strong> drought<br />

(i.e. climate) in Africa. One can only<br />

wonder why they could not see that<br />

drought was one <strong>of</strong> the country’s<br />

constraints on development. I do not<br />

think that such an omission could<br />

happen today. Earlier, the 1968-1973<br />

drought was linked to four coups<br />

d’état in the African Sahel by the mid-<br />

1970s.<br />

There are now many examples <strong>of</strong> how<br />

various sectors <strong>of</strong> society (insurance,<br />

re-insurance, commerce, energy, food<br />

production, water) have already come<br />

to realize that climate information<br />

(including, but not limited to, forecasts)<br />

can be used for the benefit <strong>of</strong> an<br />

individual, a corporation, an economic<br />

sector or a country.<br />

Problem climates<br />

In 1960, Pr<strong>of</strong>. G. Trewartha wrote a<br />

book entitled The Earth’s Problem Climates<br />

(University <strong>of</strong> Wisconsin<br />

Press). He suggested that several climates<br />

around the globe are so normal<br />

as to be unworthy <strong>of</strong> special attention<br />

by meteorologists.<br />

I have some concerns about Trewartha’s<br />

notion <strong>of</strong> “problem climates”.<br />

For example, is such a statement<br />

still valid today, given what we<br />

have learned about climate variability<br />

and change since 1960? Are there<br />

really areas on the globe that could be<br />

viewed as “climatically so normal or<br />

usual that they require little comment?”<br />

Should we also be asking<br />

questions about societies’ role in the<br />

creation <strong>of</strong> problem climates? In other<br />

words, from the perspective <strong>of</strong> climate,<br />

are there “problem societies”?<br />

Personally, I believe that all regional<br />

climates can be considered to be<br />

problem climates for the inhabitants,<br />

their activities and for the ecosystems<br />

on which they depend for their survival<br />

or livelihood.<br />

Problem societies<br />

I suggested earlier that climate is<br />

neutral, if you remove people from<br />

the equation. While we tend to focus<br />

on the “climate problem”, it is<br />

important to make explicit the fact<br />

that societies have the potential to<br />

cause changes in atmospheric<br />

processes that, in turn, generate<br />

problems with which societies must<br />

contend. Humans have used the land<br />

surface in adverse ways that disrupt<br />

the expected functioning <strong>of</strong> the climate<br />

system. As a result, climate<br />

regimes can become degraded.<br />

The level <strong>of</strong> the Aral Sea has dropped<br />

over a 40-year period. This situation<br />

provides a perfect example <strong>of</strong> what<br />

I refer to as a problem society. The<br />

Aral, sandwiched between two Central<br />

Asian deserts, was the fourth<br />

largest inland sea in the world. Today,<br />

it is on the path to extinction. The<br />

decision to divert large amounts <strong>of</strong><br />

water from Central Asia’s two major<br />

rivers that flow into the Aral Sea<br />

changed the water balance that had<br />

existed between stream inflow to the<br />

sea and evaporation from the sea’s<br />

surface.<br />

An image from space (see next page)<br />

shows a major duststorm in the<br />

south-western USA during the<br />

severe drought <strong>of</strong> 1976/1977 that<br />

began along about a 200-mile political<br />

border. A meteorologist studying<br />

severe storms examined the image<br />

and decided to investigate. He asked<br />

how a duststorm could begin along a<br />

200-mile straight line. He discovered<br />

that the reason was that the two<br />

Recent books illustrating the interest various<br />

sectors <strong>of</strong> society have in climate<br />

American states had different laws<br />

governing the use <strong>of</strong> groundwater.<br />

Ways that society makes climate<br />

serve the people<br />

There are many obvious ways that<br />

people and societies have sought to<br />

make their local climates “work” to<br />

ensure their survival on a sustained<br />

basis, not only for enhancing their<br />

well-being. The following list contains<br />

some obvious ways, as well as some<br />

not-so-obvious ones.<br />

purposes<br />

Concept development (comparative<br />

advantage, precautionary principle,<br />

resource-management techniques,<br />

etc.)<br />

Learning about the techniques in the<br />

way that land is used in different<br />

regions is instructive. For example,<br />

under some climatic conditions, it is<br />

necessary to plant crops up and down<br />

a hillside (vertically), whereas, in other<br />

places with different climate conditions,<br />

it is necessary to plant crops<br />

across the slopes (horizontally) in<br />

order to terrace the hillside and avoid<br />

erosion <strong>of</strong> the soil.<br />

In the semi-arid High Plains Region <strong>of</strong><br />

Texas (USA), farmers have been<br />

reported to be running out <strong>of</strong> water<br />

throughout each decade <strong>of</strong> the past 100<br />

years. Yet, at the proverbial 11th hour,<br />

farmers have managed to develop a<br />

new method in water use that helped to<br />

keep the farms productive.<br />

The battle between a farmer’s economic<br />

activities and his contemporary<br />

climate regime continues. Forecasting<br />

how the future climate will<br />

be affected as the global climate<br />

changes, e.g. as it warms, is problematic:<br />

will there be new extremes<br />

to cope with in places where they<br />

had not occurred before? Will storms<br />

become more frequent and more<br />

severe? Meanwhile, populations<br />

increase in urban areas and along the<br />

coasts. Water is in increasingly short<br />

supply and clean water in many<br />

places is non-existent.<br />

Decision-making under<br />

uncertainty<br />

Decision-makers are constantly<br />

under pressure to make decisions<br />

with less-than-perfect information<br />

about the issues on which they must<br />

decide. Some decision-makers are<br />

risk-averse (i.e. conservative; need<br />

more data before acting). Others are<br />

risk-takers; they decide with the<br />

information at hand, weighing the<br />

cost <strong>of</strong> no action against the cost <strong>of</strong><br />

an action.<br />

Still others are risk-makers: they<br />

make risky decisions that create risk<br />

for others but not for themselves<br />

and it is up to others to deal with<br />

the consequences, which are<br />

<strong>of</strong>ten negative. The risk-making<br />

decision-makers, however, remain<br />

safe from potentially adverse impacts.<br />

One such example would be as follows:<br />

policy-makers in a country’s<br />

capital city decide about land use in<br />

rural areas without seeking any informational<br />

input from the local stakeholders,<br />

who have considerable<br />

knowledge about the characteristics<br />

<strong>of</strong> the land and local climate, as well<br />

as about potential thresholds for, or<br />

constraints on, its potential uses.<br />

Riding the variability curve<br />

Climate is variable on all time-scales,<br />

from months to millennia. We know<br />

that. Time-scales <strong>of</strong> direct interest to<br />

society are generally in the month-todecade<br />

range. Climate is variable from<br />

season to season, year to year and<br />

decade to decade. If societies can figure<br />

out in advance how climate will<br />

vary on these various time-scales,<br />

decision-makers would be in an<br />

advantageous position to respond<br />

with greater effectiveness by preparing<br />

for, and capitalizing on, those<br />

probable and foreseeable changes.<br />

So, without perfect information about<br />

the future state <strong>of</strong> the atmosphere (or<br />

society, for that matter), they resort to<br />

a reliance on the forecasting <strong>of</strong><br />

change. They also rely to varying<br />

degrees on the monitoring <strong>of</strong><br />

changes. They may even try to identify<br />

similar situations outside their<br />

country’s borders at locations where<br />

similar climate impacts had occurred<br />

in order to get a glimpse <strong>of</strong> possible<br />

impacts, in the event that no decision<br />

or action is taken. An example or two<br />

can be instructive.<br />

The goal <strong>of</strong> rangeland managers is to<br />

keep the stocking rates <strong>of</strong> the rangefed<br />

livestock (cattle, sheep, goats,<br />

camels) in balance with the amount <strong>of</strong><br />

water and vegetative cover available<br />

as fodder. In such areas, however, the<br />

rainfall is highly variable from year to<br />

year and is skewed to dryness (more<br />

dry episodes than wet ones). The<br />

challenge is to determine how to<br />

Deforestation in the Amazon


Landsat satellite imagery (left) and moderate resolution imaging spectroradiometer (right)<br />

on the Aqua satellite on 12 August 2003<br />

manage herd size to avoid overgrazing<br />

the vegetation and excessive trampling<br />

<strong>of</strong> the soils. The manager must<br />

try to forecast and therefore “ride” (or<br />

better yet “track”) the variability curve<br />

as close as possible. They must rely<br />

on the use <strong>of</strong> both forecasts, as well<br />

as the “precautionary principle”.<br />

A second example comes from fisheries<br />

management. Each season,<br />

fishermen try to land a large amount<br />

<strong>of</strong> commercially valuable species <strong>of</strong><br />

interest to them. But variability in fish<br />

populations is high from year to year.<br />

How to manage exploitation in a way<br />

that produces safe yields <strong>of</strong> fish while<br />

protecting the standing stock <strong>of</strong> fish<br />

populations, on which the future fish<br />

productivity and fish catches depend?<br />

The usual scenario is that an abundance<br />

<strong>of</strong> fish attracts additional fishing<br />

vessels: that scenario ends up with<br />

too many boats trying to catch a dwindling<br />

number <strong>of</strong> fish.<br />

So, the overriding objective for decisionmakers<br />

is to track as closely as possible<br />

the variability curves for productivity<br />

<strong>of</strong> climate-sensitive resources.<br />

Failure to do so results in poor<br />

resource management and, ultimately,<br />

environmental degradation.<br />

The two faces <strong>of</strong> climate<br />

Climate has a bright side<br />

There is a bright (or sunny) side to climate.<br />

The point here is that the climate<br />

in most regions has been suitable<br />

for its local inhabitants. They<br />

learn how to cope, for the most part,<br />

with their climate and environmental<br />

settings (means, modes, extremes<br />

and even rare events). For some,<br />

societies learn how to prepare so as<br />

to prevent or mitigate the worst<br />

impacts <strong>of</strong> climate variability. For others,<br />

they can do little but withstand<br />

the rare extreme and have to rely on<br />

cleaning up after the death and<br />

destruction. I am going out on a<br />

proverbial tree limb to suggest that,<br />

in most locations, people are able to<br />

provide minimal food for their families,<br />

either by growing it or by trading<br />

goods for it.<br />

Today, however, bad news dominates<br />

the airwaves and newspapers. Bad<br />

news makes for attractive headlines<br />

and captures the attention <strong>of</strong> listeners<br />

and readers. Good weather is not<br />

news to the media: when have you<br />

seen an article that said “No flood<br />

today” or “No drought today”? Apparently,<br />

“normal” weather is not newsworthy.<br />

Even to governments, good<br />

weather is not really news. Governments<br />

are more interested in climate<br />

conditions that have some sort <strong>of</strong><br />

adverse impact, because they have<br />

the responsibility to protect their citizens<br />

from the worst impacts <strong>of</strong> natural<br />

hazards.<br />

Climate also has a dark side<br />

People are more fascinated by the<br />

“dark side” <strong>of</strong> climate, its extremes<br />

and the adversities that accompany<br />

them. For example, societies measure<br />

the importance <strong>of</strong> tropical storms<br />

according to their characteristics (e.g.<br />

high wind speed) as well as their<br />

impacts on societies (number <strong>of</strong><br />

deaths; amount <strong>of</strong> destruction).<br />

As noted earlier and <strong>of</strong>ten, climate<br />

varies on all time-scales and the<br />

causes <strong>of</strong> those variations are not yet<br />

well known. It is especially difficult to<br />

forecast many <strong>of</strong> those changes and<br />

variations with great reliability. Thus,<br />

if only one word could be used in<br />

relation to the climate system,<br />

I would choose the word “uncertainty.”<br />

Historical records, forecasts,<br />

projections, modelling output, climate<br />

knowledge and atmospheric<br />

119


120<br />

measurements are all subject to<br />

uncertainties.<br />

Making matters more difficult when it<br />

comes to understanding the behaviour<br />

<strong>of</strong> present-day and past climate is<br />

the occurrence <strong>of</strong> climate change over<br />

the next several decades.<br />

Climate scientists need to make a<br />

shift in their thinking<br />

Before the onset <strong>of</strong> the Industrial Revolution<br />

that began in the mid-1700s,<br />

human activities affected only local<br />

areas as a result <strong>of</strong> pollution from<br />

fires, the burning <strong>of</strong> coal and from<br />

land clearing. Humanity’s ability to<br />

influence climate on the global scale<br />

was not feasible.<br />

With the continuously growing emissions<br />

<strong>of</strong> greenhouse gases (especially<br />

carbon dioxide) since the beginning <strong>of</strong><br />

the Industrial Revolution and with the<br />

increasing dependence on nitrogenbased<br />

fertilizers, as well as the development<br />

<strong>of</strong> chlor<strong>of</strong>luorocarbons (each<br />

<strong>of</strong> them being a radiatively active<br />

greenhouse gas), in addition to clearing<br />

large swaths <strong>of</strong> land (e.g. tropical<br />

rainforests), human activities today<br />

clearly have the wherewithal to alter<br />

the chemistry (and therefore temperature)<br />

<strong>of</strong> the global atmosphere.<br />

Although there is some debate led by<br />

a relatively small number <strong>of</strong> climatechange<br />

sceptics about the ability <strong>of</strong><br />

humans to alter the global climate, it<br />

is clearly foreseeable that humans can<br />

influence global climate. No one questions<br />

the fact that global climate has<br />

warmed in the past century. The controversy<br />

has been about whether it<br />

was human-induced, natural or a combination<br />

<strong>of</strong> the two.<br />

Thus, the climate system, which is<br />

usually described only by its physical<br />

and biological components (sea ice,<br />

glaciers, sun, oceans, forests, soils,<br />

etc.) must now be described to<br />

include societal factors. Humans are<br />

now part <strong>of</strong> the global climate system<br />

and graphics that are used by scientists<br />

to represent that system must<br />

show humans as a component<br />

together with sea ice, forests, etc.<br />

How scientists see climate: through<br />

its statistics<br />

<strong>of</strong> concern to the atmospheric science<br />

People for the most part are aware <strong>of</strong><br />

the climate <strong>of</strong> the location in which<br />

they live, at least in a passive way.<br />

They are also aware, to varying<br />

degrees, <strong>of</strong> the climate conditions in<br />

other locations as well. Many people<br />

also know about tourist locations that<br />

where they live). They have learned<br />

how to live with their climate. For<br />

many people, climate is neither the<br />

best for their needs nor the worst: it is<br />

tolerable.<br />

There is a general belief among scientists<br />

that the public does not really<br />

understand (some suggest that they<br />

never will) the proper use <strong>of</strong> probability<br />

statements as they relate to<br />

weather and climate conditions. Nevertheless,<br />

one cannot deny that the<br />

public is quite aware <strong>of</strong> the many risks<br />

(chances) that they face and take each<br />

day. The public is not ignorant <strong>of</strong> what<br />

it means to take a risk.<br />

The different socio-economic sectors<br />

are primarily interested in one aspect<br />

or another <strong>of</strong> climate. Farmers, for<br />

example, are interested in seasonal<br />

changes in rainfall and temperature<br />

for reasons related to crop production—when<br />

to plant, fertilize, harvest.<br />

Water-resource managers may focus<br />

on annual and interannual time-scales<br />

egions at risk have become increasingly<br />

concerned about “deep climate<br />

change”, “a major change”.<br />

A research community focused on<br />

“deep climate change” has developed<br />

that is focused almost exclusively<br />

on climate-change issues.<br />

Everyone undertaking research or formulating<br />

policies related to coping<br />

with atmospheric processes—<br />

weather, climate and “deep” climate<br />

change—is concerned about extreme<br />

meteorological events, but each is<br />

concerned for different reasons.<br />

Those concerned with weather want<br />

to improve forecasting or response<br />

on short notice. Those interested in<br />

seasonal climate are concerned about<br />

the frequency and intensity in the<br />

occurrence <strong>of</strong> extremes. Those concerned<br />

about climate change want to<br />

know if and where there will be more<br />

extreme events and whether they will<br />

be more intense (e.g. an increase in<br />

the number <strong>of</strong> superstorms <strong>of</strong> one<br />

type or another).<br />

Seasonality is an aspect <strong>of</strong> variability<br />

that deserves special consideration.<br />

All flora and fauna, as well as most<br />

people and their socio-economic<br />

activities, are influenced by the<br />

expected natural flow <strong>of</strong> the seasons.<br />

Any disruption to that natural flow—a<br />

longer winter, a short or drier growing<br />

season, an earlier frost, a poor harvest<br />

at the end <strong>of</strong> the hunger season—can<br />

cause great harm to those<br />

dependent on an uninterrupted flow<br />

<strong>of</strong> the seasons. Two-thirds <strong>of</strong> the<br />

inhabitants <strong>of</strong> the world are dependent<br />

on the natural flow <strong>of</strong> the seasons,<br />

as are most industries.<br />

How society sees climate: through<br />

its impacts<br />

To many individuals, climate by itself<br />

is not likely to be the most important<br />

thing on one’s mind in general.<br />

Though people want to know before<br />

they go to bed at night what the<br />

weather might be the following day,<br />

they <strong>of</strong>ten do not change their<br />

intended behaviour. They want to<br />

know, but do not necessarily want to<br />

act on, the forecasts that they hear.<br />

What they do care about is how the<br />

climate or weather is likely to influence<br />

their activities, especially their<br />

livelihoods, i.e. their budget, as suggested<br />

in the following list:<br />

Food<br />

Agriculture<br />

Energy<br />

Health<br />

Disasters<br />

Commerce<br />

Manufacturing<br />

Trade<br />

Aid<br />

For corporate executives working in<br />

climate-sensitive sectors, their concern<br />

is about how climate anomalies<br />

or extremes might affect directly or<br />

indirectly their financial “bottom line”,<br />

i.e. pr<strong>of</strong>its.<br />

Obviously, agricultural activities and<br />

water-resource management are<br />

greatly affected by weather and climate<br />

conditions in a given location,<br />

especially where crops are grown and<br />

where livestock is raised. Yields can<br />

be affected, as well as total production.<br />

The climatology <strong>of</strong> a region<br />

determines what can be grown with<br />

some degree <strong>of</strong> reliability over the<br />

long term. For export crops, it is also<br />

valuable for decision-makers in one<br />

region to know about the climate conditions<br />

in regions elsewhere that grow<br />

competing crops in the international<br />

marketplace.<br />

Food production is <strong>of</strong> great concern to<br />

governments for domestic consumption<br />

needs and, in cases <strong>of</strong> poor production<br />

years, for import needs.<br />

Energy demand and supply are<br />

affected by weather and climate conditions.<br />

As for public health, numerous<br />

water- and airborne infectious diseases<br />

are also influenced by weather<br />

and climate conditions, as are hydrometeorological<br />

hazards.<br />

Weather and climate affect manufacturing<br />

(production levels and sales),<br />

trade and aid in a variety <strong>of</strong> ways that<br />

are specific to what is being manufactured<br />

(unavailability <strong>of</strong> raw materials,<br />

or inability to sell goods due to anomalous<br />

weather or climate). They also<br />

affect the <strong>transport</strong>ation <strong>of</strong> goods and<br />

provision <strong>of</strong> services (airplane scheduling,<br />

aircraft accidents, road maintenance,<br />

etc.). Many technology-related<br />

innovations have been devised to<br />

bypass the constraints imposed by<br />

seasonality, such as refrigeration, air<br />

conditioning, heating, irrigation, <strong>transport</strong>ation,<br />

personal mobility, glass<br />

greenhouses, etc.<br />

What does society do to buffer<br />

itself from climate?<br />

Since the beginning <strong>of</strong> human life on<br />

Earth, there has been a constant<br />

conflict between people and the<br />

elements (e.g. the climate system).<br />

Societies and individuals have<br />

developed many evasive actions and<br />

techniques in attempts to avoid the<br />

wrath <strong>of</strong> the natural world. The farmer<br />

who early on tried to plant corn or<br />

wheat in winter soon failed and likely<br />

perished. We have learned how to<br />

deal with the changes in the seasons.<br />

We have even found ways to bring the<br />

seasons to us rather than wait for<br />

them to occur naturally: we have<br />

invented ways to generate heat, cold,<br />

cool, wet, dry conditions thRough<br />

burning fuels, refrigeration, air<br />

conditioning, and humidifiers,<br />

respectively.<br />

We have come up with concepts that<br />

allow us to eat produce out <strong>of</strong> season<br />

by trading and <strong>transport</strong>ation.<br />

Bananas can be sold on the streets <strong>of</strong><br />

Moscow in the dead <strong>of</strong> winter,<br />

because they were grown in Ecuador<br />

and protected from cold temperatures<br />

during shipment.<br />

Companies have invented medicines<br />

that prevent certain diseases in areas<br />

where those diseases are endemic.<br />

The fact is that the list <strong>of</strong> ways that<br />

societies have learned to buffer themselves<br />

from the impacts <strong>of</strong> a varying<br />

climate is extremely long and, in many<br />

cases, place-specific (using caves as<br />

refrigerators, for example).<br />

There are co-existing, as well as<br />

conflicting, perceptions <strong>of</strong> climate<br />

Three ways that people view climate<br />

are as a resource, as a hazard, and as<br />

a constraint. As a resource, people<br />

look at precipitation amounts and timing,<br />

seasonality, frost-free periods, the<br />

length <strong>of</strong> growing seasons, heating<br />

degree days, etc. Climate provides<br />

the necessary amount <strong>of</strong> precipitation,<br />

sunlight or cloud cover, temperature<br />

and so forth, each <strong>of</strong> which helps to<br />

make some people view climate as a<br />

resource.<br />

Climate as a hazard is the view <strong>of</strong> climate<br />

that captures the most attention.<br />

It is what the media report on<br />

most frequently. Hollywood films<br />

<strong>of</strong>ten depict climate-related hazards:<br />

twisters, floods, droughts, fires, hurricanes,<br />

pest invasions, seasonal outbreaks<br />

<strong>of</strong> infectious diseases, etc.<br />

Climate-related hazards will continue<br />

to be a major societal concern as well<br />

as a major societal attractor.<br />

Climate has been discussed as a constraint<br />

on economic development<br />

prospects: too hot, too cold, too wet,<br />

too dry, too humid, lack <strong>of</strong> seasonal<br />

changes for one human activity or<br />

another. It was once used as a reason<br />

Headlines from around the world indicating interest in floods and droughts<br />

in support <strong>of</strong> colonialism, with northern<br />

countries trying to get the southern<br />

countries to be “more productive”.<br />

In fact, one researcher wrote<br />

about the “air-conditioning revolution”<br />

suggesting that, with the<br />

advent <strong>of</strong> air-conditioning, pockets <strong>of</strong><br />

temperate-zone (i.e. productive) climate<br />

could be created in the midst <strong>of</strong><br />

the tropics (so the argument went).<br />

In sum, societies have, since the first<br />

settlements, sought to buffer themselves<br />

from the elements. That has<br />

been their challenge in the past and<br />

will continue to be so in the future.<br />

Climate as a resource<br />

There have been several highly productive<br />

regions around the globe<br />

called “breadbaskets.” Today we recognize<br />

that the North American Great<br />

Plains is one <strong>of</strong> the most important<br />

breadbaskets for food production,<br />

domestically as well as for the world.<br />

Other productive regions can be found<br />

for different types <strong>of</strong> agricultural and<br />

livestock production in most countries:<br />

wheat and cattle in Argentina and Australia;<br />

soybeans in southern Brazil; rice<br />

in Viet Nam, etc. Other regions, however,<br />

have, at one time or another,<br />

been considered national or regional<br />

breadbaskets, only to fail to reach their<br />

food-production potential, usually<br />

because <strong>of</strong> political factors as opposed<br />

to poor climate conditions.<br />

Interestingly, what may be a resource<br />

for one type <strong>of</strong> activity may not be<br />

seen as such by others. For example,<br />

in the San Luis Valley in Colorado,<br />

USA, some farmers needed more rain<br />

for their crops late in the growing<br />

season, while others wanted dry<br />

sunny weather to ensure a good harvest<br />

<strong>of</strong> a different crop. Those wanting<br />

more moisture for their fields<br />

(hops for beer production) authorized<br />

cloud-seeding activities. Those who<br />

opposed it took up arms and fired on<br />

the cloud-seeding aircraft. The project<br />

was halted. This example underscores<br />

the fact that climate conditions<br />

alone do not determine whether<br />

or not climate in a given location can


Weblines and headlines about superstorms<br />

be called a resource. It is how that climate<br />

is being “used” by society and<br />

individuals living within that climate<br />

regime that determines whether the<br />

climate is a resource or a constraint<br />

on economic development prospects.<br />

This could be called “the climate+<br />

factor.”<br />

Climate as a hazard: El Niño as a<br />

hazard-spawner<br />

El Niño (or the El Niño/Southern Oscillation)<br />

is a relatively recently identified<br />

natural process <strong>of</strong> air-sea interaction<br />

in the tropical Pacific. We have only<br />

really begun to take this equatorial<br />

Pacific phenomenon seriously since<br />

the early 1970s (and most seriously<br />

after the 1982/1983 El Niño <strong>of</strong> the<br />

century).<br />

The natural hazards community<br />

advised me some years ago that the<br />

El Niño phenomenon was not a natural<br />

hazard. They argued that it was like<br />

winter; winter just “is”. All this, in<br />

spite <strong>of</strong> the fact that El Niño meets<br />

each <strong>of</strong> the criteria used to define a<br />

hazard as laid out by the hazards<br />

research community. Yet, El Niño<br />

“spawns” and is associated with climate<br />

and climate-related hazards<br />

around the world (droughts, floods,<br />

frosts, infectious disease outbreaks).<br />

People fear the hazard aspect <strong>of</strong> the<br />

ENSO extremes.<br />

There is some forecast value associated<br />

with El Niño, based on historical<br />

records and timely monitoring across<br />

the Equator in the Pacific. Some<br />

regions are clearly affected and the<br />

geophysical mechanisms can be<br />

shown to exist without question,<br />

especially around the Pacific rim. The<br />

climate and weather anomalies in<br />

other regions have been linked to El<br />

Niño events through statistical correlations,<br />

even though the mechanisms<br />

may remain unclear.<br />

Although the forecasting <strong>of</strong> the onset<br />

<strong>of</strong> El Niño events (as well as their<br />

intensity) remains difficult, once an El<br />

Niño begins, it will continue through a<br />

process lasting 12 months or so.<br />

Knowing an event is in progress<br />

enables those regions and activities<br />

likely to be affected by it to use the El<br />

Niño information to take evasive<br />

actions when possible. Some countries<br />

will have more lead time to prepare<br />

for it than others, however.<br />

Global warming and the weather<br />

There is a great deal <strong>of</strong> speculation<br />

about how a warmer atmosphere<br />

might affect the frequency and magnitude<br />

and even the location <strong>of</strong> extreme<br />

events to which we have already<br />

become accustomed. Today there is<br />

growing concern that global warming<br />

will have a major influence on<br />

extreme events. For many this is not<br />

just a growing concern. It is an outright<br />

fear.<br />

We must ask ourselves how well<br />

societies are coping with the variations<br />

in climate today. One would<br />

have to conclude that, for the most<br />

part, “not very well”, occasional successes<br />

notwithstanding. In order to<br />

prepare for a warmer future, societies<br />

must improve the ways that they<br />

cope with today’s extreme and anomalous<br />

events. If we are not well prepared<br />

today to identify societal<br />

strengths and weaknesses in<br />

response to climate- and weatherrelated<br />

hazards, how can we expect<br />

to be better prepared for changes in<br />

the patterns <strong>of</strong> anomalies in the<br />

future?<br />

In the 1990s, a new category <strong>of</strong><br />

storm seemed to emerge: the superstorm.<br />

These are what might be<br />

referred to as blockbuster storms,<br />

exhibiting record-setting wind speeds<br />

for tornadoes or tropical storms. Scientists<br />

increasingly talk about the<br />

possible increase in the intensity <strong>of</strong><br />

an extreme event, for example,<br />

superhurricanes, supertyphoons and<br />

supercyclones.<br />

123


124<br />

Scientists and societies have always<br />

been concerned about extreme climate<br />

and climate-related events. They<br />

keep track <strong>of</strong> record-setting events:<br />

hurricanes, typhoons, tornadoes, ice<br />

storms, freezes, heat waves,<br />

droughts severity, etc.<br />

Initially, the question was raised about<br />

why this category had emerged in the<br />

1990s. Was it media hype or are<br />

these events really deserving <strong>of</strong> the<br />

“super” label? This has to be determined<br />

on a case-by-case basis.<br />

Global warming is another hazard<br />

<strong>of</strong> global concern<br />

In the personal view <strong>of</strong> the author, the<br />

industrialized north produces the<br />

lion’s share <strong>of</strong> carbon dioxide. These<br />

countries now argue that the developing<br />

countries <strong>of</strong> the south will be<br />

come the major producers <strong>of</strong> this<br />

greenhouse gas in the future.<br />

It is the north that saturated the<br />

atmosphere with greenhouse trace<br />

gases. I therefore say: “should they<br />

not take the first steps to clean up the<br />

atmosphere that they polluted on their<br />

way to becoming industrialized?”<br />

Is forecasting getting too much<br />

attention?<br />

Meteorologists and climatologists are<br />

heavily involved in trying to forecast or<br />

project the future state as well as<br />

behaviour <strong>of</strong> the Earth’s atmosphere.<br />

The public for its part is bombarded<br />

every day and in every way with forecasts<br />

<strong>of</strong> weather and climate (via electronic<br />

and print media). Yet forecasts<br />

make up only a small part <strong>of</strong> what<br />

could be identified much more broadly<br />

as climate knowledge. Pr<strong>of</strong>essionally<br />

produced and transmitted forecasts as<br />

weather- and climate-related information<br />

to inform decisions are in constant<br />

competition with individual and group<br />

perceptions about the benefits <strong>of</strong><br />

using forecasts, regional climate history<br />

and folk knowledge held by people<br />

about a particular climate regime.<br />

Interestingly, the public has a different<br />

view <strong>of</strong> the success rate <strong>of</strong> forecasts<br />

from those who produce those forecasts.<br />

The public is much less aware<br />

<strong>of</strong> the nuances as well as the use and<br />

meaning <strong>of</strong> probabilistic forecasts for a<br />

given location (a specific place versus<br />

a general area).<br />

Climate and weather forecasts are<br />

<strong>of</strong>ten compared to other environmental<br />

indicators and beliefs (right or wrong) in<br />

order to calibrate their correctness.<br />

Sometimes forecasts reinforce the<br />

other indicators that the public relies<br />

on, while at other times they are in conflict<br />

with the other indicators.<br />

the development <strong>of</strong> core<br />

skills and capabilities worldwide<br />

that, in turn, will help to build a<br />

government’s, an organization’s or<br />

an individual’s effectiveness and<br />

sustainability.<br />

There is an urgent need for climaterelated<br />

capacity-building in meteorological<br />

and hydrological services, in<br />

climate-sensitive sectors <strong>of</strong> society<br />

and among the public.<br />

Foster the notion <strong>of</strong> Climate<br />

Affairs<br />

Climate Affairs is, in fact, an attempt<br />

at capacity-building by getting people<br />

to look at climate-society-environment<br />

interactions as parts <strong>of</strong> a holistic<br />

system. Society can no longer<br />

afford the luxury <strong>of</strong> remaining igno-


ant about the climate system and<br />

its newfound role in it. Governments<br />

cannot afford to ignore the<br />

many ways that climate-societyenvironment<br />

interactions influence<br />

the well-being <strong>of</strong> their citizens. The<br />

challenge, then, is how to educate<br />

people and policy-makers at the<br />

highest levels about the ways that<br />

atmospheric processes influence<br />

their lives.<br />

Selling climate<br />

”Selling” climate knowledge today<br />

can make selling climate-change<br />

information tomorrow an easier task.<br />

The meteorological community and<br />

its fellow travellers have been very<br />

successful in the past two decades in<br />

“wholesaling” the importance <strong>of</strong> climate<br />

information, broadly defined.<br />

Broadcasting to the public that climate<br />

is important to know about<br />

seems to have worked. People on the<br />

street are aware <strong>of</strong> the global warming<br />

issue. They are certainly aware <strong>of</strong><br />

extreme events and anomalies such<br />

as El Niño. “Retailing” to the public,<br />

including its policy-makers, the value<br />

<strong>of</strong> climate knowledge is the hard part.<br />

Fine-tuning climate knowledge to the<br />

disparate specific needs <strong>of</strong> potential<br />

users, groups, companies, sectors or<br />

government agencies is, however,<br />

the hard labour-intensive task that lies<br />

ahead.<br />

Turning “what ought to be” into<br />

“what is”<br />

With regard to what ought to be the<br />

value <strong>of</strong> using climate information<br />

(or the cost <strong>of</strong> not using it), it is<br />

important to note that, in theory,<br />

there are many uses <strong>of</strong> such information<br />

in a constraint-free world. In<br />

practice, however, various constraints<br />

arise to restrict the optimal<br />

beneficial use <strong>of</strong> climate knowledge.<br />

We need to identify those constraints<br />

and work to minimize, if not<br />

remove, them.<br />

Revisit lessons learned<br />

It is quite clear and normal that “lessons<br />

learned” about how better to<br />

prepare for, or cope with, potential<br />

climate-related hazards are identified<br />

after each disaster. Decades <strong>of</strong><br />

reports with such lessons learned<br />

about droughts, floods, fires and disease<br />

exist, but, unfortunately, they<br />

rest on bookshelves, unused. In<br />

fact, lessons are <strong>of</strong>ten only identified<br />

but not necessarily learned. It is<br />

imperative that we take the time to<br />

revisit past lessons learned, and use<br />

them when applicable to contemporary<br />

situations.<br />

Climate knowledge audit: who is<br />

using what, and how<br />

“Climate audit” is a phrase that<br />

refers to a way to start a process that<br />

identifies those who are in need <strong>of</strong><br />

climate knowledge or are aware <strong>of</strong> its<br />

existence but need guidance on how<br />

best to use it. In other words, who is<br />

using what, and how are they using<br />

it? Climate-related audits in societies<br />

can help to identify what climate<br />

information is being used as well as<br />

what is not being used. Audits can<br />

help the climate impacts and applications<br />

communities know where they<br />

have done a good job and where they<br />

need to focus their efforts in the<br />

future.<br />

Many <strong>of</strong> us have knowledge about climate.<br />

We are empowered. It is our<br />

responsibility to present, as well as<br />

future, generations to share that<br />

knowledge.<br />

Climate knowledge is power.<br />

Sharing climate knowledge is<br />

empowering. <br />

Deluge in<br />

Mumbai,<br />

India<br />

By U.S. De 1 , G.S. Prakasa Rao 2 ,<br />

D.M. Rase 3<br />

Introduction<br />

On 26 July 2005, the skies over Mumbai<br />

released the heaviest rainfall ever<br />

recorded at that location: at Santacruz,<br />

an accumulated total <strong>of</strong> 944 mm was<br />

recorded at 03 UTC on 27 July—the<br />

primary synoptic observation time.<br />

Previous all-time highest rainfalls<br />

recorded in 24 hours (available in the<br />

National Data archives <strong>of</strong> the India<br />

Meteorological Department) are for a<br />

station Amini Divi (11°07’N and<br />

72°44’E), an <strong>of</strong>fshore island in the Arabian<br />

Sea, which recorded 1 168 mm<br />

on 6 May 2004, while Cherrapunji<br />

(25°15’N and 91°44 E), a hill station in<br />

the north-east <strong>of</strong> the country recorded<br />

1 563 mm on 16 June 1995. The<br />

Mumbai event <strong>of</strong> 26/27 July has a<br />

rather distinct feature. While the rain<br />

recorded at Santacruz (19°01’N and<br />

72°51’E) was 944 mm, that recorded<br />

at Colaba (18°54’N and 72°49’E)—only<br />

25 km away (Figure 1)—was a mere<br />

73 mm. It can thus be inferred that<br />

the phenomenal rain in Mumbai was<br />

associated with a mesoscale cloud<br />

system centred over Santacruz.<br />

The location and the event<br />

The west coast <strong>of</strong> India extending<br />

from about 8°N to about 23°N has<br />

heavy rainfall spells during the southwest<br />

monsoon season. The stations<br />

located on the western ghats (a<br />

mountainous region with elevation <strong>of</strong><br />

1-1.5 km close to the coast) therefore<br />

receive copious rain which feeds the<br />

rivers flowing eastwards across the<br />

Deccan plateau.<br />

In July 2005, a spell <strong>of</strong> heavy rain continued<br />

until the following week. Heavy<br />

rains in Maharashtra for a period <strong>of</strong><br />

nearly one week commencing on<br />

27 July caused dams in Pune, Karad<br />

and Solapur to overflow. The water<br />

released from these dams, coupled<br />

with intermittent rains for 8-10 days<br />

caused disastrous flooding and associated<br />

landslides in Maharashtra. The<br />

worst affected sectors were rail and<br />

air communications. The international<br />

airport at Mumbai was closed for<br />

nearly 30 hours on 27/28 July. Landslides<br />

and flooding caused more than<br />

1 000 deaths, half in the Mumbai met-<br />

ropolitan area. As the floodwaters<br />

receded, deaths from waterborne diseases<br />

were also reported from these<br />

areas. This is a common occurrence in<br />

megacities after floods (De and Sinha<br />

Ray, 2000).<br />

Heavy rainfall events since 1950 are<br />

shown in Figure 2. During the past<br />

55 years, either Santacruz or Colaba<br />

recorded 28 such cases in a single<br />

day, <strong>of</strong> which there were only three<br />

occasions when both stations simultaneously<br />

received 250 mm (or more)<br />

per day. In the case <strong>of</strong> greater rainfall,<br />

i.e. more than 500 mm a day,<br />

there were only two such occasions<br />

(5 July 1974 and 2 July 1984) at<br />

Colaba. On these two days, Santacruz<br />

recorded 375.2 mm and<br />

240.1 mm rainfall, respectively. For<br />

Colaba, the rainfall on 5 July 1974<br />

was 575.6 mm, while, for Santacruz,<br />

on 10 June 1991, the total was<br />

399 mm—the highest so far.

Atmospheric circulation<br />

The synoptic monsoon system has<br />

been studied by many authors and a<br />

summary can be found in Das (1998)<br />

and Rao (1976). The synoptic-scale<br />

systems associated with the release<br />

<strong>of</strong> such heavy precipitation over the<br />

western coast <strong>of</strong> India, specially in the<br />

neighbourhood <strong>of</strong> Mumbai, are:<br />

• A monsoon depression travelling<br />

Monthly normal rainfall in millimetres (1961-1990)<br />

• A mid-tropospheric circulation over<br />

the Gujarat/Maharashtra coast;<br />

• An <strong>of</strong>fshore vortex in the lower troposphere<br />

close to Mumbai in the<br />

Arabian Sea;<br />

• An <strong>of</strong>fshore trough in the Arabian<br />

Sea extending from the Maharashtra<br />

coast southwards on the sealevel<br />

chart.<br />

A combination <strong>of</strong> these systems also<br />

occurs, which results in heavy falls. In<br />

addition, thermodynamic parameters<br />

and their variation are linked with such<br />

sharp rainfall events (Dutta and De,<br />

1999). The synoptic system which<br />

Synoptic situation on 26 July 2005<br />

(AIWS IMD 2005)<br />

The axis <strong>of</strong> the monsoon trough on<br />

the sea-level chart passes over northwest<br />

India, centre <strong>of</strong> a well-marked<br />

low-pressure area <strong>of</strong> Orissa and then<br />

south-eastwards to the north<br />

Andaman Sea. An <strong>of</strong>fshore trough at<br />

sea-level passes along the west coast<br />

<strong>of</strong> India.<br />

Synoptic situation on 27 July 2005<br />

(AIWS IMD 2005)<br />

The axis <strong>of</strong> the monsoon trough<br />

passes through north-west India and<br />

the centre <strong>of</strong> the low-pressure area,<br />

which lies over south-eastern Madhya<br />

Pradesh and south-eastwards to the<br />

north Andaman Sea. The <strong>of</strong>fshore<br />

trough at sea-level along the west<br />

coast persists.<br />

Warnings<br />

Based on the synoptic analysis and<br />

satellite/radar observations, the<br />

Regional Meteorological Centre,<br />

Mumbai, and the National Forecasting<br />

Centre (Weather Central) issued warnings<br />

<strong>of</strong> intermittent rainfall with a few<br />

heavy falls and a warning <strong>of</strong> scattered<br />

heavy rainfall for Maharashtra. The<br />

local forecast for Mumbai had also<br />

included warnings <strong>of</strong> impending very<br />

heavy rainfall. The Tropical Rainfall<br />

Measuring Mission satellite images<br />

for 26 July 2005 for hourly rain rate<br />

and accumulated rainfall are shown in<br />

Figure 3 (a) and (b), respectively.<br />

caused huge waterlogging. This led to<br />

near-total failure <strong>of</strong> traffic and communication<br />

lines. The estimated loss to<br />

Mumbai in terms <strong>of</strong> industry and commerce<br />

was about US$ 10 million.<br />

Studies made in recent years in different<br />

parts <strong>of</strong> the world have shown that<br />

damage costs have increased significantly<br />

as infrastructure and housing<br />

have developed in vulnerable areas.<br />

Conclusion<br />

Losses from weather- and climaterelated<br />

disasters since the 1960s have<br />

increased by a factor <strong>of</strong> 40 (IPCC,<br />

1998). This highlights the vulnerability<br />

<strong>of</strong> societies to extreme climatic<br />

events. In the aftermath <strong>of</strong> this natural<br />

disaster, the need for sustainable<br />

urban development is once more<br />

brought into focus. Urban flooding is a<br />

major threat to cities and thus urban<br />

flood management in developing<br />

countries also requires an evaluation<br />

<strong>of</strong> socio-economic issues related to<br />

land use and urban development<br />

(Tucci, 2004). While disasters <strong>of</strong> such<br />

magnitude are rare, preparedness for<br />

addressing them at the local, regional<br />

and national level should be our top<br />

priority. Studies by De and Prakasa<br />

Rao (2004) have shown an increasing<br />

long-term trend in the rainfall in the<br />

four megacities <strong>of</strong> India—Delhi, Mumbai,<br />

Chennai and Kolkata.<br />

The global<br />

climate<br />

system in<br />

2005<br />

This article is drawn from the <strong>WMO</strong> Statement<br />

on the Status <strong>of</strong> the Global Climate in 2005<br />

(<strong>WMO</strong>-No. 998). It is also available on the Web:<br />

Global temperatures in 2005<br />

The analyses made by various leading<br />

centres indicate that the global mean<br />

surface temperature in 2005 was<br />

0.47°C to 0.58°C above the 1961-<br />

1990 annual average <strong>of</strong> 14°C. This<br />

places 2005 as one <strong>of</strong> the two<br />

warmest years in the temperature<br />

record since 1850. (The year 1998 had<br />

annual surface temperatures averag-<br />

ing 0.52°C* above the same 30-year<br />

mean.) The last 10 years, 1996-2005,<br />

with the exception <strong>of</strong> 1996 and 2000,<br />

are the warmest years on record.<br />

The latest improved analysis <strong>of</strong> global<br />

temperature made by the Hadley<br />

Centre, The Met Office, UK, marks the<br />

year as the second warmest (0.47°C<br />

above average). Based on similar<br />

improved temperature analyses, but<br />

different methodology, the National<br />

Climatic Data Center, NOAA, USA,<br />

ranks 2005 as the warmest year<br />

(0.52°C above the 1961-1990 annual<br />

average). The analysis <strong>of</strong> the Goddard<br />

Institute <strong>of</strong> Space Studies, United<br />

States, also ranks the year as the<br />

warmest (0.58°C above the 1951-1980<br />

annual average). All the temperature<br />

values have uncertainties, which arise<br />

mainly from gaps in data coverage.<br />

The sizes <strong>of</strong> the uncertainties are<br />

such that the global average temperature<br />

for 2005 is statistically indistinguishable<br />

from that <strong>of</strong> 1998. Based on<br />

the Hadley Centre analyses, averaged<br />

separately for both hemispheres, surface<br />

temperatures in 2005 for the<br />

northern hemisphere (0.65°C above<br />

the 1961-1990 average) were the<br />

warmest and for the southern hemisphere<br />

(0.28°C above the 1961-1990<br />

average) were the fifth warmest in<br />

the instrumental record from 1850 to<br />

the present.<br />

Since the beginning <strong>of</strong> the 20th century,<br />

the global average surface temperature<br />

has increased by about<br />

0.6°C. However, this increase has not<br />

been continuous and has risen sharply<br />

since 1976.<br />

Areas <strong>of</strong> significant warmth were<br />

widespread with large areas <strong>of</strong> Africa,<br />

Australia, Brazil, the Russian Federa-<br />

* This value is based on the new temperature analysis <strong>of</strong> the Hadley Centre, UK, introduced<br />

for the first time this year. In the earlier temperature analysis, the temperature anomaly<br />

value for 1998 was +0.54°C.<br />

<strong>WMO</strong> annual statements<br />

on the status <strong>of</strong> the global<br />

climate<br />

<strong>WMO</strong> has issued these statements<br />

to provide credible scientific information<br />

on climate and its<br />

variability since 1993. They<br />

complement the periodic assessments<br />

<strong>of</strong> the <strong>WMO</strong>/United<br />

Nations Environment Programme<br />

Intergovernmental Panel on<br />

Climate Change.<br />

tion, Scandinavia, Canada, China and<br />

south-western USA showing significantly<br />

above-average temperatures.<br />

Much <strong>of</strong> the North Atlantic and southwest<br />

Pacific Oceans were also significantly<br />

warm, as was the Gulf <strong>of</strong><br />

Alaska. Sea-surface temperatures in<br />

the North Atlantic in 2005 were the<br />

warmest on record.<br />

Regional temperature anomalies<br />

Large portions <strong>of</strong> the northern hemisphere<br />

experienced warm conditions<br />

in 2005 that exceeded 90 per cent <strong>of</strong><br />

the annual temperatures recorded in<br />

the 1961-1990 period (the 90th<br />

percentile). Parts <strong>of</strong> the North Atlantic<br />

and Indian Oceans had warm temperatures<br />

exceeding the 98th percentile.<br />

Only a few small areas in the southern<br />

hemisphere experienced temperatures<br />

below the 10th percentile.<br />

The large-scale climate phenomenon El<br />

Niño can contribute to above-average<br />

warmth, as was the case with the<br />

extremely strong 1997/1998 episode. A<br />

weak El Niño episode that developed in<br />

mid-2004 continued until the beginning<br />

<strong>of</strong> 2005, but sea-surface temperatures in<br />

the central and east central equatorial<br />

Pacific decreased early in the year and<br />

the episode ended by late February. The<br />

129


130<br />

record warmth in 2005 is notable as there<br />

was little influence <strong>of</strong> the El Niño event<br />

on the 2005 global temperatures.<br />

For Australia, 2005 was the hottest year<br />

since records commenced in 1910, with<br />

about 95 per cent <strong>of</strong> the continent experiencing<br />

above average mean<br />

temperatures. The previous annual<br />

temperature record was set in 1998.<br />

The nationwide maximum temperature<br />

anomaly in April was +3.11°C, the<br />

largest anomaly recorded for any month<br />

since 1950. During the January-May<br />

period, the hottest maximum temperatures<br />

on record exacerbated the<br />

exceptionally dry conditions.<br />

In India, Pakistan and Bangladesh,<br />

extremely harsh heat waves in May<br />

and June brought maximum temperatures<br />

<strong>of</strong> between 45°C and 50°C. The<br />

maximum temperatures over these<br />

regions were 5°C to 6°C above the<br />

long-term average. The delayed southwest<br />

monsoon rains allowed the heat<br />

wave to persist into June, claiming at<br />

least 400 lives in India.<br />

A severe heat wave gripped southwestern<br />

USA from early to mid-July,<br />

setting up numerous temperature<br />

records. Central Canada experienced<br />

its warmest and most humid summer<br />

on record. In 2005, the number <strong>of</strong> hot<br />

days in Toronto was more than twice<br />

its average value. In China, the 2005<br />

summer seasonal temperature was<br />

one <strong>of</strong> the warmest since 1951.<br />

Severe heat-wave conditions also<br />

affected much <strong>of</strong> southern Europe<br />

and North Africa during July. In Algeria,<br />

the heat wave in July pushed temperatures<br />

as high as 50°C and claimed<br />

more than a dozen lives.<br />

Extremely cold temperatures affected<br />

much <strong>of</strong> the Balkan region during the<br />

first half <strong>of</strong> February. In Morocco, a<br />

cold wave in January dropped temperatures<br />

to as low as -14°C. In Sevlievo,<br />

Bulgaria, a 50-year temperature record<br />

Climate highlights <strong>of</strong> 2005<br />

It was one <strong>of</strong> the two warmest<br />

years in the temperature record<br />

since 1850.<br />

Australia had its hottest year on<br />

record.<br />

The ozone hole ranked as the<br />

third largest ever recorded<br />

(after 2000 and 2003).<br />

Prolonged drought in the<br />

Greater Horn <strong>of</strong> Africa put<br />

11 million people at risk from<br />

starvation.<br />

The Atlantic hurricane season<br />

was the most active on record.<br />

was broken with temperatures dropping<br />

to as low as -34°C. During<br />

December, much <strong>of</strong> Japan, the<br />

Korean peninsula, China, Mongolia<br />

and parts <strong>of</strong> the eastern Russian Federation<br />

experienced significantly<br />

colder-than-average temperatures. A<br />

series <strong>of</strong> winter storms brought below<br />

normal temperatures over parts <strong>of</strong><br />

central Europe in December.<br />

Prolonged drought in some regions<br />

Long-term drought continued in parts<br />

<strong>of</strong> the Greater Horn <strong>of</strong> Africa, including<br />

southern Somalia, eastern Kenya,<br />

south-eastern Ethiopia, north-eastern<br />

United Republic <strong>of</strong> Tanzania and Djibouti.<br />

Both the long (March-June) and<br />

short (October-December) rainy seasons<br />

brought below-normal precipitation<br />

over this region. Over 11 million<br />

people in Ethiopia, Djibouti, Somalia<br />

and Kenya were at risk <strong>of</strong> starvation<br />

due to the effects <strong>of</strong> recent droughts.<br />

Sporadic rainfall during the 2004/2005<br />

rainy season caused serious shortfalls<br />

in the cereal harvest in Zimbabwe,<br />

Malawi, Angola and Mozambique. At<br />

least 5 million people in Malawi were<br />

threatened with hunger arising from<br />

the worst drought in a decade.<br />

Multi-month drought conditions also<br />

affected much <strong>of</strong> western Europe during<br />

July, August and September. During<br />

the period October 2004 to June<br />

2005, rainfall was less than half the<br />

normal in areas <strong>of</strong> the United Kingdom,<br />

France, Spain and Portugal.<br />

Neighbouring Spain and Portugal experienced<br />

the worst drought conditions<br />

since the late 1940s, with 97 per cent<br />

<strong>of</strong> Portugal affected by severe to<br />

extreme drought. The dry conditions<br />

also aggravated wildfires in the region.<br />

The long-term hydrological drought<br />

continued for southern and eastern<br />

Australia, but eased slightly in the second<br />

half <strong>of</strong> the year. The period January<br />

to May was exceptionally dry for<br />

much <strong>of</strong> Australia, with 44 per<br />

cent <strong>of</strong> the continent experiencing<br />

rainfall in the lowest 10 per cent <strong>of</strong><br />

the recorded totals. During this<br />

period, Australia received an average<br />

<strong>of</strong> only 168 mm <strong>of</strong> rainfall, the second<br />

lowest January-May total since<br />

records commenced in 1900.<br />

Across the USA, moderate-to-severe<br />

drought persisted throughout parts <strong>of</strong><br />

the Pacific North-West eastward into<br />

the northern Rocky Mountains. At the<br />

end <strong>of</strong> winter, moderate-to-extreme<br />

drought affected 72 per cent <strong>of</strong> the<br />

Pacific North-West. Below-normal<br />

rainfall beginning in December 2004<br />

caused severe drought conditions<br />

over southern parts <strong>of</strong> Brazil, where<br />

corn and soybean crops were<br />

severely damaged. In Brazil, the<br />

southernmost state <strong>of</strong> Rio Grande do<br />

Sul, which is one <strong>of</strong> the country’s<br />

most prolific agricultural states, was<br />

the worst affected. The state <strong>of</strong> Amazonas<br />

experienced the worst drought<br />

in nearly 60 years, resulting in record


low water levels in the Amazon River.<br />

In October, drought conditions<br />

extended further south into neighbouring<br />

Paraguay. By the end <strong>of</strong> the<br />

year, drought affected much <strong>of</strong> central<br />

USA from the southern Great Plains<br />

to the western Great Lakes. Parts <strong>of</strong><br />

Illinois, Arkansas, Oklahoma and<br />

Texas had the driest March-December<br />

in the 111-year record.<br />

Rainfall and flooding<br />

Global precipitation in 2005 was near<br />

the 1961-1990 average. Wetter-than-average<br />

conditions prevailed over<br />

Central America, eastern parts <strong>of</strong><br />

Europe, India, China and Canada.<br />

Drier-than-average conditions were<br />

widespread across eastern Australia,<br />

Brazil, parts <strong>of</strong> western Europe, central<br />

Africa and, in the USA, the Mississippi<br />

valley and southern Great Plains<br />

region.<br />

Early indications <strong>of</strong> a very active Atlantic hurricane season proved accurate.<br />

The seasonÕs stor ms caused a vast amount <strong>of</strong> damage, death and destruction.<br />

Damage estimates have already been put at more than US$ 100<br />

billion (mostly from Hurricane Katrina) and over 2 800 deaths (mostly from<br />

Katrina and Stan).<br />

The season saw 27 named tropical storms, making it the most active<br />

season on record (the previous record was for 21 named storms in 1933).<br />

Thirteen became hurricanes—the most to form in a single season. Of<br />

these, seven were major hurricanes, one short <strong>of</strong> the 1950 record. Fifteen<br />

systems made landfall—another record. It is the first hurricane season,<br />

Atlantic or Pacific, to exhaust the list <strong>of</strong> names and resort to Greek letters<br />

for naming.<br />

Wilma was the most powerful hurricane, in terms <strong>of</strong> both wind speed and<br />

air pressure, ever measured in the Atlantic basin. Wilma also broke records<br />

for fastest development, going from tropical storm status to Category 5<br />

hurricane in less than 24 hours.<br />

The last storm, Zeta, developed on 30 December and persisted until 6<br />

January 2006. The Atlantic hurricane season usually runs from 1 June to<br />

30 November.<br />

The south-west monsoon during June-<br />

September brought unprecedented<br />

heavy rain and widespread massive<br />

flooding to parts <strong>of</strong> western and southern<br />

India, affecting more than 20<br />

million people and resulting in more<br />

than1800 deaths. On 27 July, Mumbai<br />

recorded unprecedented heavy rainfall<br />

<strong>of</strong> 944 mm in the previous 24 hours,<br />

which is an all-time 24-hour rainfall<br />

record for the city. The devastating<br />

floods in Mumbai caused economic<br />

losses <strong>of</strong> about US$ 3.5 million (see<br />

article on page 126).<br />

Heavy rainfall continued unabated in<br />

south-eastern parts <strong>of</strong> India, during<br />

the north-east monsoon season <strong>of</strong><br />

October-December. The associated<br />

devastating floods affected more than<br />

2 million people with at least<br />

300 fatalities and caused considerable<br />

adverse socio-economic impacts. The<br />

north-east monsoon also produced<br />

extremely heavy rainfall in parts<br />

During the third week <strong>of</strong> June, consecutive<br />

heavy rainstorms in parts <strong>of</strong><br />

Fujian, Guangdong and Guangxi<br />

provinces in southern China killed at<br />

least 170 people and affected some<br />

21 million people. Heavy rainfall<br />

across southern China continued into<br />

July, with floods affecting the upper<br />

reaches <strong>of</strong> the Huaihe basin. Across<br />

northern China, heavy rainfall during<br />

late September to early October produced<br />

extensive flooding in the Hanjiang<br />

rain, snow and flooding to the southwestern<br />

USA. Los Angeles, California,<br />

experienced its second wettest rainfall<br />

season on record. In January, a<br />

major snowstorm affected areas <strong>of</strong><br />

the north-eastern USA with more than<br />

30 cm <strong>of</strong> accumulated snow. Record<br />

rainfall occurred in the north-east USA<br />

in the autumn <strong>of</strong> 2005, with three<br />

storm systems affecting the region.<br />

Across Canada, 2005 was the wettest<br />

year on record. In June, three major<br />

rain events in southern Alberta produced<br />

the costliest natural disaster in<br />

the province’s history. Calgary experienced<br />

its wettest month ever in<br />

125 years <strong>of</strong> record.<br />

Heavy rains in January and February<br />

caused massive flooding in Guyana’s<br />

capital, Georgetown, and surrounding<br />

areas affecting more than 290 000<br />

people. In February, at least two<br />

weeks <strong>of</strong> heavy rainfall in Colombia<br />

and Venezuela caused river flooding


and landslides that resulted in the<br />

deaths <strong>of</strong> at least 80 people. Across<br />

Costa Rica and Panama, heavy rains<br />

in January caused flooding that was<br />

responsible for displacing more than<br />

35000 people. In October, Hurricane<br />

Stan caused flooding and mudslides<br />

in parts <strong>of</strong> Mexico, Nicaragua, Honduras<br />

and El Salvador, leading to the<br />

deaths <strong>of</strong> hundreds <strong>of</strong> people.<br />

Cold weather and heavy snowfall<br />

that began in January continued in<br />

February in south-west Asia, causing<br />

avalanches. In parts <strong>of</strong> Tajikistan,<br />

two metres <strong>of</strong> snow accumulated<br />

in two weeks. During<br />

February, sections <strong>of</strong> northern Pakistan<br />

and neighbouring areas <strong>of</strong><br />

northern India received heavy snowfall,<br />

described as the worst in two<br />

decades. In India, at least 230 people<br />

died as a result <strong>of</strong> the extreme<br />

winter weather. In Pakistan's northwest<br />

province, 360 deaths in February<br />

were attributed to flooding,<br />

landslides and avalanches. Heavy<br />

rains in March also caused flooding<br />

in parts <strong>of</strong> western Pakistan and<br />

Afghanistan, resulting in more than<br />

200 fatalities. In December, recordbreaking<br />

heavy snowfall occurred in<br />

parts <strong>of</strong> Japan, claiming at least<br />

80 lives. A record maximum snowfall<br />

<strong>of</strong> 58 cm was recorded at Akita<br />

in December.<br />

In New Zealand, the Bay <strong>of</strong> Plenty<br />

floods in May were most disastrous,<br />

with unprecedented heavy<br />

rainfall causing widespread damage<br />

in parts <strong>of</strong> Tauranga. It was one <strong>of</strong><br />

the wettest years on record in parts<br />

<strong>of</strong> the Bay <strong>of</strong> Plenty and Hawke’s<br />

Bay. In the South Pacific, heavy<br />

rains and high storm surges owing<br />

to tropical cyclones Olaf and Percy<br />

impacted the coastal areas <strong>of</strong><br />

Samoa, American Samoa, Cook<br />

Islands and Manua Islands, causing<br />

coastal flooding and displacing thousands<br />

<strong>of</strong> people.<br />

Antarctic ozone hole<br />

In 2005, the size <strong>of</strong> the Antarctic<br />

ozone hole was close to 2003 values<br />

and well above the 1995-2004 average.<br />

The maximum size <strong>of</strong> the<br />

Antarctic ozone hole, 24.4 million<br />

km 2 , was reached in the third week<br />

<strong>of</strong> September. The ozone hole in 2005<br />

dissipated earlier than usual, in mid-<br />

November. Based on satellite<br />

observations, the ozone hole <strong>of</strong> 2005<br />

ranks as the third largest ever<br />

recorded after 2000 and 2003. In<br />

2005, greater ozone depletion took<br />

place in the Arctic. During the spring<br />

<strong>of</strong> 2005, in large portions <strong>of</strong> the Arctic<br />

region, average values <strong>of</strong> total ozone<br />

were 30-45 per cent lower than<br />

comparable values during the early<br />

1980s.<br />

Arctic sea ice<br />

Typically, September is the month<br />

with the least sea-ice extent in the<br />

Arctic. By the end <strong>of</strong> September<br />

2005, the Arctic sea-ice extent<br />

dropped far below the average for<br />

the fourth consecutive year. It was<br />

about 20 per cent less than the<br />

1979-2004 average, the lowest<br />

extent ever observed during the<br />

satellite record since 1979. Satellite<br />

information suggests a general<br />

decline <strong>of</strong> 8 per cent <strong>of</strong> Arctic seaice<br />

extent at the end <strong>of</strong> September<br />

over the last 25 years. Warmerthan-average<br />

Arctic temperatures<br />

and an early arrival <strong>of</strong> the sea-ice<br />

melt season are the main causes<br />

for the intensification <strong>of</strong> the sea-ice<br />

decline in 2005.<br />

Global crop<br />

production<br />

review 2005*<br />

The following is an annual review <strong>of</strong><br />

regional crop production, comparing<br />

2005 with the previous year. For both<br />

the northern and southern hemispheres,<br />

these summaries reflect<br />

growing-season weather for crops<br />

that were harvested in the calendar<br />

year <strong>of</strong> 2005. For most countries,<br />

changes in production for 2005 are<br />

based on crop estimates released by<br />

the United States Department <strong>of</strong> Agriculture<br />

(USDA) in February 2006.<br />

Wheat and coarse grain: summary<br />

In 2005, world wheat production<br />

declined about 2 per cent from 2004.<br />

Wheat production increased in<br />

Canada, Mexico, the Islamic Republic<br />

<strong>of</strong> Iran, the Russian Federation,<br />

Ukraine, Kazakhstan, China, Pakistan,<br />

South Africa and Australia. It declined<br />

in the USA, countries <strong>of</strong> the European<br />

Union, Morocco, Algeria, Tunisia,<br />

Turkey, Brazil and Argentina. The<br />

* Prepared by the Joint Agricultural Weather<br />

Facility <strong>of</strong> the US Department <strong>of</strong> Agriculture<br />

country-level changes in 2005 wheat<br />

production from 2004 are shown in<br />

Figure 1. World coarse-grain production<br />

was down 5 per cent in 2005.<br />

Production increased in Hungary,<br />

Turkey, China, Argentina and South<br />

Africa. It declined in the USA, Canada,<br />

most <strong>of</strong> the European Union, Ukraine,<br />

the Russian Federation, Mexico, India,<br />

Brazil and Australia.<br />

In the USA, wheat production (winter,<br />

spring and durum) declined 2 per cent<br />

from 2004. Production totals <strong>of</strong> hard<br />

red winter and white winter wheat<br />

were similar to the previous year, but<br />

s<strong>of</strong>t red winter wheat production was<br />

down 19 per cent from 2004. Excessive<br />

autumn wetness in the delta dramatically<br />

reduced s<strong>of</strong>t red winter<br />

wheat planted area. US spring wheat<br />

production was also down, coming in<br />

11 per cent below 2004. US corn production<br />

was down 6 per cent from the<br />

record 2004 crop. A regional drought<br />

in the central corn belt lowered corn<br />

production in northern Illinois and<br />

adjacent areas.<br />

In Canada, wheat production rose<br />

4 per cent in 2005, due to generally<br />

favourable growing conditions and an<br />

improvement <strong>of</strong> long-term drought<br />

that had plagued the Prairies in previous<br />

years. Unlike 2004, the first<br />

autumn freeze arrived later than usual,<br />

allowing spring crops to mature normally.<br />

Barley production was down<br />

about 5 per cent due to lower yield<br />

and reduced area. Corn production<br />

rose about 7 per cent, with crop yield<br />

in Ontario rebounding from 2004.<br />

The European Union experienced a<br />

10 per cent decline in wheat production,<br />

due to contrasting weather<br />

extremes in eastern and western<br />

Europe. France, Germany, the United<br />

Kingdom, Poland, Italy and Spain<br />

account for about 80 per cent <strong>of</strong> total<br />

wheat production. In 2005, drought<br />

plagued western Europe after a<br />

favourable growing season in 2004.<br />

On the Iberian Peninsula, drought<br />

reached record proportions, significantly<br />

reducing crop yields and depleting<br />

reservoirs and irrigation supplies.<br />

In France, dryness was not as<br />

extreme, but still significant enough to<br />

lower wheat production by 7 per cent.<br />

In contrast, persistent wetness in<br />

south-eastern Europe flooded fields<br />

and damaged crops. Wheat production<br />

declined in Hungary (12 per cent),<br />

Figure 1 — Country-level change in 2005 wheat production from 2004


Bulgaria (14 per cent) and Romania<br />

(9 per cent), due mostly to yield<br />

reductions caused by persistent,<br />

untimely rain. In addition, there were<br />

significant harvest delays across Hungary<br />

and the Balkans as a result <strong>of</strong><br />

excessive rain from July into September,<br />

although drier weather in October<br />

allowed fieldwork to resume. Farther<br />

north, modest reductions over the<br />

previous year’s wheat crop were<br />

reported in Germany and the United<br />

Kingdom (6 and 3 per cent, respectively).<br />

In Poland, ideal winter and<br />

spring moisture was followed by an<br />

untimely spell <strong>of</strong> dry weather in late<br />

June and early July, causing an 11 per<br />

cent decline in wheat production.<br />

Winterkill was confined to north-west<br />

Poland, where an early February<br />

freeze occurred in a snow-free area.<br />

Western drought and eastern flooding<br />

also caused European Union coarse<br />

grain production to drop 13 per cent,<br />

with corn and barley production<br />

decreasing 10 and 14 per cent, respectively.<br />

Below-normal summer rainfall<br />

coupled with periods <strong>of</strong> extreme heat<br />

lowered corn production in France by<br />

19 per cent. Barley production in Spain<br />

was down 59 per cent in 2005, due to<br />

severe drought on the Iberian<br />

Peninsula (Figure 2). Corn production<br />

declined 10-25 per cent from 2004<br />

across most European Union countries.<br />

Corn production in France was<br />

down 19 per cent. Likewise, barley<br />

production in most European Union<br />

countries decreased 6-10 per cent<br />

from the 2004 crop, although production<br />

gains were reported in Italy (7 per<br />

cent) and Denmark (6 per cent).<br />

The unseasonably wet weather across<br />

south-eastern Europe reduced the<br />

region’s coarse grain production. Corn<br />

production was down 25 per cent in<br />

Romania, despite nearly identical corn<br />

acreage to 2004. Likewise, barley production<br />

decreased 21 per cent owing<br />

to flooding and persistent wetness.<br />

In the Russian Federation, winter<br />

wheat is grown mostly in the Southern<br />

District and southern areas <strong>of</strong><br />

the Central and Volga Districts. Most<br />

<strong>of</strong> the spring wheat crop is grown<br />

from the Volga District eastward<br />

through the Siberia District. The<br />

combination <strong>of</strong> favourable growing<br />

conditions, along with a 15 per cent<br />

increase in planted area, resulted in<br />

an 11 per cent increase in winter<br />

wheat production from 2004. In the<br />

autumn <strong>of</strong> 2004, mild weather and<br />

adequate moisture in October and<br />

November favoured winter wheat<br />

establishment and alleviated prior<br />

concerns about a lack <strong>of</strong> planting<br />

moisture in September.<br />

Unusually mild weather in November<br />

promoted later-than-usual<br />

growth <strong>of</strong> winter wheat in most<br />

areas. The winter-wheat crop<br />

entered dormancy one to two<br />

weeks later than usual. Unseasonably<br />

mild weather provided<br />

favourable overwintering conditions<br />

for the winter-wheat crop during<br />

most <strong>of</strong> the winter. Winterkill for<br />

winter grains was reportedly 8 per<br />

cent, which is below the 10-year<br />

average <strong>of</strong> 13 per cent and below<br />

the previous winter’s winterkill <strong>of</strong> 10<br />

per cent. In March, the coldest<br />

weather since 1996 maintained an<br />

unusually late snowpack, delaying<br />

the greening <strong>of</strong> winter wheat.<br />

Figure 2 —<br />

Cumulative<br />

precipitation for<br />

north-western<br />

Spain<br />

In April, a warming trend melted the<br />

late-season snow cover and prompted<br />

greening in winter wheat, about two<br />

weeks later than usual. Adequate precipitation<br />

during key stages <strong>of</strong> crop<br />

development benefited crops in May<br />

and June, and was followed by<br />

favourable harvest weather. Regarding<br />

spring wheat, weather conditions<br />

favoured timely planting in the Urals<br />

and Siberia Districts, while wet<br />

weather in the Volga District slowed<br />

early planting activities. During the<br />

remainder <strong>of</strong> the growing season,<br />

mild weather and above-normal precipitation<br />

favoured crops in the Urals<br />

and western areas in Siberia, while<br />

periodic heat and dryness lowered<br />

yield prospects in key spring-wheat<br />

producing areas in the eastern Volga<br />

District and eastern areas <strong>of</strong> Siberia.<br />

These declines in crop prospects<br />

were not made up in other areas that<br />

experienced more favourable<br />

weather, resulting in a 4 per cent<br />

decline in spring-wheat production<br />

over the previous year. Coarse grain<br />

production in Russia declined by 7 per<br />

cent in 2005, due mainly to a decline<br />

in area planted with spring barley.<br />

Spring barley is grown throughout the<br />

Russian Federation and accounts for<br />

about 50 per cent <strong>of</strong> coarse grain production.<br />

More favourable weather<br />

resulted in a 26 per cent increase in<br />

2005 rye production. Although<br />

135


136<br />

favourable weather boosted yield<br />

prospects for corn, production fell 9<br />

per cent due to an 11 per cent decline<br />

in planted area.<br />

In Ukraine, most <strong>of</strong> the wheat grown<br />

in the country consists <strong>of</strong> winter varieties.<br />

In the autumn <strong>of</strong> 2004, near- to<br />

above-normal precipitation in September<br />

and October provided adequateto-abundant<br />

moisture for crop emergence<br />

and establishment, and mild<br />

autumn weather conditions promoted<br />

later-than-usual growth. Crops<br />

entered dormancy during the second<br />

half <strong>of</strong> November, about one to two<br />

weeks later than usual. Unusually mild<br />

weather during the winter provided<br />

favourable overwintering conditions<br />

for crops. Winterkill totalled only 3 per<br />

cent, the lowest level in 15 years. In<br />

March, the coldest weather since<br />

1996 maintained snow cover two to<br />

three weeks later than usual, keeping<br />

winter wheat dormant.<br />

In April, a warming trend prompted<br />

greening in winter wheat about two<br />

weeks later than usual. In May,<br />

unseasonably warm, dry weather prevailed<br />

over the eastern half <strong>of</strong> the<br />

country, causing the winter wheat<br />

crop, which advanced through the<br />

highly weather- sensitive heading<br />

stage <strong>of</strong> development, to rely on rapidly<br />

declining subsoil moisture<br />

reserves to sustain normal crop development.<br />

May’s dryness in the region<br />

was followed by above-normal precipitation<br />

in early June, benefiting the<br />

crop in the grain-filling stage.<br />

Farther west, timely rains in May and<br />

early June favoured winter wheat that<br />

advanced through the reproductive<br />

phase <strong>of</strong> development. In July,<br />

weather conditions favoured rapid harvest<br />

activities. Overall, winter wheat<br />

production increased 8 per cent from<br />

2004, due mainly to the extremely<br />

low winterkill that resulted in a higher<br />

area, as well as similar yield prospects<br />

to those <strong>of</strong> the previous year. Coarse<br />

grain production was down 21 per<br />

cent from 2004 levels. Production for<br />

both spring barley and corn production<br />

declined 19 per cent. For spring barley,<br />

wet weather at planting and early<br />

growth stages resulted in shallow root<br />

systems. Hot, dry weather in May<br />

negatively impacted the shallowrooted<br />

crop. Despite favourable<br />

weather conditions for corn, production<br />

declines were caused by a 28 per<br />

cent reduction in planted area from<br />

the previous year.<br />

In Kazakhstan, spring grains (mostly<br />

spring wheat and spring barley)<br />

account for most <strong>of</strong> the total grain<br />

production. Spring barley typically<br />

accounts for about 80 per cent <strong>of</strong><br />

Kazakhstan’s coarse grain production.<br />

Furthermore, most <strong>of</strong> the wheat<br />

grown in the country is <strong>of</strong> a spring<br />

variety. Periods <strong>of</strong> dry weather helped<br />

spring grain planting in May, while<br />

above-normal precipitation in June<br />

favoured crop emergence and growth.<br />

Major grain-producing areas in the<br />

north-central portion <strong>of</strong> the country<br />

received near- to above-normal precipitation<br />

in July, boosting yield<br />

prospects. As a result, wheat production<br />

in 2005 increased 11 per cent<br />

from 2004. Coarse grain production<br />

remained at last year’s levels, mainly<br />

due to less area planted to barley.<br />

In Turkey, winter wheat and barley<br />

production decreased 3 per cent. In<br />

the Islamic Republic <strong>of</strong> Iran,<br />

favourable growing-season weather<br />

and a continued expansion in area<br />

boosted wheat production 4 per cent,<br />

resulting in another year <strong>of</strong> record<br />

wheat production.<br />

In north-western Africa, a southward<br />

extension <strong>of</strong> the drought that gripped<br />

the Iberian Peninsula resulted in periods<br />

<strong>of</strong> untimely dryness. Consequently,<br />

significant reductions were<br />

seen in both wheat and barley production.<br />

In Morocco, hardest hit by the<br />

drought, wheat production decreased<br />

45 per cent from 2004. Wheat yields<br />

in Morocco were down 43 per cent<br />

from 2004. In Algeria, wheat and barley<br />

production declined by 42 and<br />

70 per cent, respectively. The decline<br />

in Algerian wheat production resulted<br />

from a 30 per cent decrease in<br />

planted area and an 18 per cent<br />

decline in yield.<br />

In China, wheat production increased<br />

6 per cent due to favourable weather<br />

and increased area. Corn production<br />

increased by 3 per cent in 2005,<br />

mainly due to a 3 per cent increase in<br />

planted area.<br />

In India, a small decrease in area was<br />

<strong>of</strong>fset by a minor increase in yield,<br />

resulting in similar winter-wheat production.<br />

In Pakistan, an increase in<br />

yields and area coupled with generally<br />

favourable weather resulted in an<br />

11 per cent increase in wheat production.<br />

Indian coarse-grain production<br />

fell about 2 per cent in 2005, as a latearriving<br />

monsoon coupled with


untimely dryness in August caused<br />

yields to drop by 3 per cent.<br />

In the southern hemisphere, Australian<br />

wheat production increased<br />

6 per cent in 2005. In Western Australia,<br />

warm, showery weather during<br />

the autumn aided winter-wheat planting<br />

and establishment. A period <strong>of</strong><br />

dryness during the winter slowed<br />

growth, but near-normal rainfall and<br />

generally seasonable temperatures<br />

during the remainder <strong>of</strong> the growing<br />

season provided nearly ideal weather<br />

for reproductive to filling winter<br />

wheat. In south-eastern Australia,<br />

very dry weather during the autumn<br />

caused extensive planting delays, raising<br />

concerns that drought would significantly<br />

reduce winter-wheat production<br />

in this region. Nevertheless,<br />

soaking rain spread over south-eastern<br />

Australia in mid-June and persisted<br />

throughout the growing season<br />

greatly improving winter-wheat<br />

prospects. In northern New South<br />

Wales and southern Queensland,<br />

warm, wet weather in the autumn<br />

helped early winter- wheat development.<br />

Below-normal precipitation during<br />

the winter and spring and hot<br />

weather late in the growing season,<br />

however, were probably responsible<br />

for some declines in yield potential.<br />

In South Africa, wheat production rose<br />

about 7 per cent due to improved<br />

yields and favourable harvest weather<br />

in key production areas <strong>of</strong> Western<br />

Cape and Free State. South African<br />

corn production was up 21 per cent as<br />

the highest yields in recent memory<br />

more than <strong>of</strong>fset marginal declines in<br />

acreage. In Argentina, 2005 corn production<br />

was about 30 per cent higher<br />

than the previous year’s droughtreduced<br />

crop, mainly due to timely<br />

showers in major production areas <strong>of</strong><br />

Cordoba, Santa Fe and Buenos Aires.<br />

In contrast, winter-wheat production<br />

was down 24 per cent due to a combination<br />

<strong>of</strong> problems, including drought,<br />

a late spring freeze and untimely harvest<br />

rains in the main growing areas <strong>of</strong><br />

central Argentina. In Brazil, winterwheat<br />

production fell about 20 per<br />

cent, due to unusual wetness during<br />

harvest in Parana. Corn production fell<br />

more than 15 per cent from 2004, as a<br />

second year <strong>of</strong> summer drought<br />

impacted both the main-season and<br />

winter-corn crop.<br />

Oilseed Summary<br />

World oilseed production rose 2 per<br />

cent in 2005. Oilseed production<br />

increased in the USA, Canada, the<br />

Russian Federation, Ukraine, India,<br />

Indonesia, Brazil and Argentina, and<br />

declined in the European Union, and<br />

China.<br />

In North America, US soybean production<br />

was the second highest on<br />

record, down 1 per cent from 2004.<br />

Weather conditions were extremely<br />

favourable across northern growing<br />

areas, while drought reduced soybean<br />

yield potential from Texas north-eastward<br />

to Illinois. In Canada, rapeseed<br />

(canola) production was up 25 per<br />

cent from 2004, due to an increase in<br />

both area and yields boosted by a second<br />

season <strong>of</strong> long-term drought<br />

relief. Soybean production rose<br />

slightly due to increased yield and<br />

similar acreage levels to 2004 in<br />

Ontario.<br />

In the European Union, oilseed production<br />

in 2005 was down 2 per cent<br />

from 2004, due to drier-than-normal<br />

weather. In particular, Spain’s oilseed<br />

crop suffered substantially from the<br />

effects <strong>of</strong> drought, with a 41 per cent<br />

decrease in production. European<br />

Union rapeseed production increased<br />

1 per cent, reflecting production gains<br />

in France and the United Kingdom<br />

(11 and 21 per cent, respectively) <strong>of</strong>fset<br />

by decreases in production across<br />

the remainder <strong>of</strong> Europe. Sunflower-<br />

seed production declined in many<br />

countries, due to reduced area and<br />

unfavourable weather; Spain (49 per<br />

cent reduction) experienced the<br />

largest decline.<br />

In the Russian Federation and<br />

Ukraine, sunflower production rose<br />

35 per cent and 54 per cent, respectively<br />

in 2005. Growing-season<br />

weather conditions were favourable<br />

for sunflowers, boosting yields above<br />

the previous year. In addition, the area<br />

planted with sunflowers increased in<br />

both the Russian Federation and<br />

Ukraine.<br />

In China, below-normal rainfall and<br />

lower yields reduced 2005 winter<br />

rapeseed production by over 13 per<br />

cent. Additionally, soybean production<br />

was down about 2 per cent due in<br />

part to flooding and lower yields in<br />

key growing areas <strong>of</strong> Manchuria.<br />

In India, total oilseed production<br />

increased slightly (2 per cent) in 2005.<br />

Winter rapeseed production was up<br />

5 per cent from last year, primarily<br />

due to a 4 per cent increase in area.<br />

For the second consecutive year,<br />

summer oilseed production was<br />

mixed. Soybean production (up 9 per<br />

137


138<br />

cent) was not adversely affected by<br />

the erratic start to the 2005 monsoon<br />

season, due in part to higher acreage<br />

(6 per cent increase). Peanut (groundnut)<br />

production was down 3 per cent,<br />

mainly due to flooding in key groundnut<br />

areas <strong>of</strong> Gujarat and southern<br />

India. In Gujarat, India’s second<br />

largest groundnut-producing state,<br />

excessive monsoon rainfall flooded<br />

fields, increasing disease concerns<br />

and reducing yield potential. Farther<br />

south, India’s rabi (winter) groundnut<br />

crop was adversely impacted by<br />

unseasonably heavy rainfall during the<br />

flowering stage in October.<br />

In Argentina, soybean production rose<br />

almost 20 per cent in 2005. Nearly<br />

ideal growing conditions benefited<br />

flowering and pod-filling soybeans<br />

during January and February in the<br />

main growing areas. Similarly,<br />

sunflower production increased about<br />

10 per cent due to increased yield on<br />

marginally larger area. In southern<br />

Brazil, soybean farmers experienced a<br />

second year <strong>of</strong> drought (see Figure 3)<br />

and yields were slightly lower than<br />

those recorded in 2004. However,<br />

production was about 4 per cent<br />

higher due to a sixth consecutive year<br />

<strong>of</strong> record planted area and fewer problems<br />

with Asian Rust in northern<br />

growing areas compared with the<br />

previous year.<br />

Rice Summary<br />

World rice production rose 2 per cent<br />

in 2005. Rice production increased<br />

slightly throughout most <strong>of</strong> South-<br />

East Asia and India.<br />

In India, rice production increased<br />

2 per cent. Production increased 3 per<br />

cent in Bangladesh, which was spared<br />

from flooding for much <strong>of</strong> the season.<br />

Pakistan recorded an increase <strong>of</strong><br />

about 10 per cent due to higher yields<br />

(also up 9 per cent). In Thailand, production<br />

rose by nearly 5 per cent due<br />

to a more normal monsoon season as<br />

compared with the previous year. In<br />

Viet Nam, rice production in 2005<br />

remained virtually unchanged from<br />

the previous year. In China, 2005 rice<br />

production rose slightly, due primarily<br />

to an increase in area.<br />

Cotton Summary<br />

World cotton production declined by<br />

5 per cent in 2005. Cotton production<br />

increased in the USA, Uzbekistan, and<br />

Argentina, and declined in China,<br />

India, Pakistan, Turkey and Brazil.<br />

In the northern hemisphere, USA cotton<br />

production was up 2 per cent from<br />

2004 and reached a record high for the<br />

second consecutive year. Most <strong>of</strong> the<br />

US cotton belt experienced favourable<br />

growing and harvest conditions,<br />

although the remnants <strong>of</strong> hurricanes<br />

Katrina (late August) and Rita (late September)<br />

produced heavy rain and gusty<br />

winds in the lower Mississippi Valley.<br />

In Uzbekistan, favourable weather conditions<br />

during the growing season and<br />

autumn harvest period resulted in an<br />

8 per cent increase in cotton production.<br />

In China, production decreased by<br />

Figure 3 —<br />

Cumulative<br />

precipitation for<br />

Rio Grande Do<br />

Sul, Brazil.<br />

10 per cent. Despite favourable growing<br />

conditions in Xinjiang, wet weather<br />

on the North China Plain, while bolls<br />

were open, reduced yields. Turkish<br />

production decreased by nearly 15 per<br />

cent due to unfavourably wet weather<br />

during the cotton harvest. In India, cotton<br />

production decreased 2 per cent<br />

due in part to heavy late-season rain in<br />

northern India, which fell as cotton<br />

reached the open-boll stage <strong>of</strong> development.<br />

Production in Pakistan also<br />

dropped (14 per cent) in response to<br />

unseasonably heavy rains in September.<br />

In the southern hemisphere, Australian<br />

cotton production surged<br />

approximately 76 per cent in 2005 in<br />

response to improved soil moisture<br />

and reservoir levels. Near-normal rainfall<br />

during 2004 helped break the devastating<br />

drought that enveloped northern<br />

New South Wales and southern<br />

Queensland during 2002 and 2003,<br />

boosting moisture supplies for dryland<br />

and irrigated crops. In Argentina, production<br />

jumped 31 per cent as<br />

increased area <strong>of</strong>fset a decline in<br />

yield. In Brazil, production fell slightly<br />

as drought-reduced yields were partially<br />

<strong>of</strong>fset by a 6 per cent increase in<br />

area.


Winner <strong>of</strong> an<br />

weather<br />

prediction<br />

competition<br />

100 years ago<br />

Gabriel Guilbert (1862-1940) © Météo-France<br />

By Jean-Pierre Javelle*<br />

On 30 September 1905, the jury <strong>of</strong> the<br />

international short-range weather forecasting<br />

competition unanimously<br />

decided to award the prize to Gabriel<br />

Guilbert (1862-1940), secretary <strong>of</strong> the<br />

Commission météorologique du<br />

Calvados. The jury also gave a<br />

* Chief, Documentation Department,<br />

commendation to work carried out by<br />

Emile Durand-Gréville (1838-1913),<br />

one <strong>of</strong> the French representatives at<br />

the International Meteorological<br />

Conference in Innsbruck, which had<br />

taken place at the beginning <strong>of</strong> the<br />

month. French <strong>meteorology</strong> was<br />

therefore recognized, even though<br />

Guilbert and Durand-Gréville were not<br />

among the then approximately thirty<br />

staff <strong>of</strong> the Bureau central<br />

météorologique (BCM), the predecessor<br />

<strong>of</strong> Météo-France.<br />

The competition was organized by<br />

the Société belge d’astronomie on<br />

the occasion <strong>of</strong> the Liege (Belgium)<br />

International Exhibition and great<br />

care was taken to ensure that it<br />

would be <strong>of</strong> a serious, scientific<br />

nature. The jury was made up <strong>of</strong><br />

renowned experts, including Léon<br />

Teisserenc de Bort, Director <strong>of</strong> the<br />

Observatoire de météorologie<br />

dynamique in Trappes, who was<br />

Guilbert was a passionate meteorologist and an excellent observer and<br />

forecaster, but he also had a strong personality and a distinct taste for<br />

arguments, so had turbulent relationships with his peers. On 6 April 1886,<br />

he exhibited the “cloud sequences” which he had discovered, at the<br />

Société météorologique de France (SMF).<br />

In the SMF’s yearbook <strong>of</strong> 1891 he published the rules <strong>of</strong> forecasting based<br />

on the relationship between observations <strong>of</strong> the horizontal pressuregradient<br />

and wind speed, which he later used in 1905 in the forecasting<br />

competition.<br />

As from 1912 he prepared the weather forecasts for the daily newspaper Le<br />

Matin. During the First World War, he worked with the Bureau<br />

météorologique militaire, then in 1921 he became a first class meteorologist<br />

at the recently created Office national météorologique (ONM), which<br />

replaced the Bureau central météorologique, though this did not prevent<br />

him from harshly criticizing the ONM’s forecasting methods in the press.<br />

In the preface <strong>of</strong> his book, Les systèmes nuageux [Cloud Systems]<br />

published in 1922, Colonel Delcambre, director <strong>of</strong> the ONM, paid<br />

homage to Guilbert’s groundbreaking ideas on cloud sequences.<br />

In 1923 and 1924, Guilbert unsuccessfully proposed the organization <strong>of</strong><br />

another international weather forecasting competition. Until the end <strong>of</strong><br />

the 1930s, he continued to produce weather forecasts for Le Matin and<br />

published many popular works on weather forecasting.<br />

Twenty-four competitors entered. The<br />

first round, comprising a practical test,<br />

took place from 1 to 15 September.<br />

Each day, candidates had to send their<br />

forecasts for the next day to the<br />

Société belge d’astronomie in<br />

Brussels. After this first test, nine<br />

candidates were invited to Liege, <strong>of</strong><br />

whom seven actually went there.<br />

During the second test, from 26 to<br />

28 September, the candidates had<br />

to forecast the next day’s weather<br />

for ten situations in the past, seven<br />

having been selected at random and<br />

three because <strong>of</strong> the problems they<br />

posed. The three candidates who<br />

got the best results, Durand-<br />

Gréville, Guilbert and the Dutch<br />

forecaster, Nell, had to explain their<br />

methods and answer the jury’s<br />

questions. The jury unanimously<br />

decided to award the prize to<br />

Guilbert, but also commended<br />

Durand-Gréville for the quality <strong>of</strong><br />

some <strong>of</strong> his forecasts as well as his<br />

remarkable work on squalls. We<br />

now know that the “squall lines and<br />

bands” revealed by Durand-Gréville<br />

in 1892 foreshadowed the cold<br />

fronts made popular by the<br />

Norwegian school <strong>of</strong> <strong>meteorology</strong><br />

more than twenty years later. Pierre<br />

Duvergé recently published an interesting<br />

article in Arc-en-Ciel, the<br />

bulletin <strong>of</strong> the Association des<br />

anciens de la météorologie, summarizing<br />

the ideas <strong>of</strong> his forgotten<br />

precursor, Durand-Gréville, and<br />

highlighting his other talents as a<br />

journalist and art critic.

ago ...<br />

Pr<strong>of</strong>. H. Riehl <strong>of</strong> the University <strong>of</strong> Chicago<br />

delivers a lecture on the structure <strong>of</strong> hurricanes<br />

during the first international seminar on<br />

hurricanes (Ciudad Trujillo, Dominican Republic,<br />

16-25 February 1956).<br />

Excerpts drawn from <strong>WMO</strong> Bulletin<br />

5 (2), April 1956*<br />

This issue carried articles on the first<br />

Caribbean Hurricane seminar, the<br />

International Geophysical Year 1957-<br />

1958, activities <strong>of</strong> the Technical Commissions,<br />

utilization <strong>of</strong> wind power in<br />

India, <strong>meteorology</strong> in Europe, use <strong>of</strong><br />

micro-opaque cards in <strong>meteorology</strong>,<br />

collaboration with other international<br />

organizations, the Technical Assistance<br />

Programme, meteorological<br />

transmissions in Europe and the international<br />

scale <strong>of</strong> radiation.<br />

Caribbean Hurricane Seminar<br />

Fifty-six meteorologists, lecturers and<br />

participants from 18 countries<br />

attended the first international hurricane<br />

seminar. Topics included formation,<br />

structure and movement <strong>of</strong> hurricanes;<br />

the use <strong>of</strong> radar in tracking the<br />

movement and in determining rainfall<br />

patterns; numerical forecasting; aircraft<br />

reconnaissance; national hurricane<br />

warning systems; and construction<br />

methods necessary to minimize<br />

property damage and the loss <strong>of</strong> life in<br />

regions vulnerable to hurricanes.<br />

The Secretary-General [<strong>of</strong> <strong>WMO</strong>],<br />

Mr D.A. Davies, stated that, in general,<br />

technical assistance was given<br />

primarily to strengthen the economies<br />

<strong>of</strong> less developed nations with a view<br />

to promoting their economic and political<br />

independence and to helping<br />

them to achieve higher levels <strong>of</strong> economic<br />

and social welfare. Meteorology<br />

was an important field in this<br />

assistance. Daily weather forecasts<br />

and climatological studies assisted<br />

agriculture, aviation, sea <strong>transport</strong>,<br />

fishing and domestic industries to<br />

prosper and timely warnings <strong>of</strong> severe<br />

weather, such as hurricanes and<br />

floods, aid in minimizing the disasters<br />

caused by weather.<br />

A most important aspect <strong>of</strong> international<br />

gatherings was the opportunity<br />

for meteorologists from various countries<br />

to become acquainted. Probably<br />

no other social effort <strong>of</strong> man required<br />

closer cooperation and coordination<br />

between nations than the practice <strong>of</strong><br />

the science <strong>of</strong> <strong>meteorology</strong>. Cooperation<br />

was much easier to achieve<br />

when the parties knew each other. An<br />

impersonal request takes on a personal<br />

meaning and is not, therefore,<br />

easily dismissed.<br />

International Geophysical Year<br />

(IGY) 1957-1958<br />

The overall programme for the International<br />

Geophysical Year was the<br />

responsibility <strong>of</strong> the [then] International<br />

Council <strong>of</strong> Scientific Unions<br />

(ICSU) but <strong>WMO</strong>’s role was <strong>of</strong> great<br />

importance. A group <strong>of</strong> experts met<br />

in March 1956 to discuss outstanding<br />

questions.<br />

The experts supported a proposal<br />

that the meteorological programme<br />

should include the measurement <strong>of</strong><br />

evaporation and evapotranspiration.<br />

They also supported a proposal to<br />

include investigations using tritium,<br />

in the form <strong>of</strong> heavy water vapour,<br />

as a means <strong>of</strong> following air movement.<br />

The release <strong>of</strong> heavy water<br />

vapour over the Antarctic, for example,<br />

could contribute to a solution <strong>of</strong><br />

the problem <strong>of</strong> the mixing <strong>of</strong> Antarctic<br />

air masses with the rest <strong>of</strong> the<br />

atmosphere.<br />

The <strong>WMO</strong> Secretariat would act as an<br />

international meteorological centre for<br />

the IGY. Its main functions would be<br />

to collect the essential meteorological<br />

data and to make arrangements for<br />

supplying copies <strong>of</strong> the data to scientific<br />

institutes and researchers.<br />

Meteorological Services would be<br />

requested to supply data from their<br />

main synoptic surface stations, upperair<br />

stations and selected ships. The<br />

data would be supplied on standard<br />

forms to ensure a reasonably homogeneous<br />

presentation.The <strong>WMO</strong> IGY<br />

Unit would register the forms and<br />

send them out for reproduction on<br />

141


142<br />

micro-opaque cards. Copes <strong>of</strong> these<br />

cards would then be made available at<br />

cost price.<br />

The period 1 to 5 January 1957 would be<br />

designated as a trial period for the IGY.<br />

Utilization <strong>of</strong> wind power in India<br />

Studies were being carried out with a<br />

view to developing wind-power<br />

resources in India. This included the<br />

identification <strong>of</strong> favourable sites<br />

where the availability <strong>of</strong> power under<br />

optimum conditions could be<br />

assessed.<br />

It was concluded that large, untapped<br />

resources <strong>of</strong> wind power could be<br />

pr<strong>of</strong>itably used in rural areas for purposes<br />

such as pumping water for<br />

drinking, sanitation, irrigation <strong>of</strong> small<br />

holdings, drainage, etc. Other possible<br />

uses <strong>of</strong> windmills in rural areas are for<br />

the processing <strong>of</strong> agricultural products,<br />

such as grinding corn, threshing<br />

and oil extraction.<br />

Most regions in India have average<br />

wind velocities <strong>of</strong> less than 16 km/h.<br />

Studies <strong>of</strong> windmill efficiency had<br />

indicated that economic utilization <strong>of</strong><br />

windmills would be possible in these<br />

regions only by construction <strong>of</strong> fairly<br />

large size windmills at low cost using<br />

indigenous materials. A design project<br />

had been initiated with a prototype<br />

windmill using wood and bamboo.<br />

A proposal was now under consideration<br />

by the Government <strong>of</strong> India for<br />

utilizing wind power on a large scale in<br />

accordance with a phased programme.<br />

It was contemplated to use more than<br />

20 000 small windmills in rural areas and<br />

perhaps a few hundred medium-sized<br />

wind electric plants for electric supply,<br />

for the operation <strong>of</strong> pumping installations<br />

and for supply <strong>of</strong> electricity in out<strong>of</strong>-the-way<br />

localities for lighthouses,<br />

plantations, etc.<br />

Membership<br />

The Republic <strong>of</strong> Korea became<br />

the 94th Member <strong>of</strong> <strong>WMO</strong> on<br />

16 March 1956.<br />

Collaboration with other international<br />

organizations<br />

<strong>WMO</strong> was represented at the sixth<br />

session <strong>of</strong> the FAO Indo-Pacific<br />

Fisheries Council (Tokyo, 30 September-<br />

14 October 1955). The Council<br />

promoted the development and proper<br />

utilization <strong>of</strong> living aquatic resources <strong>of</strong><br />

the Indo-Pacific area, through international<br />

cooperation.<br />

Weather is an important factor in fishing<br />

operations and in several other<br />

aspects <strong>of</strong> the fishing industry, such as<br />

the design <strong>of</strong> fishing craft and gear and<br />

the faunal distribution over the oceans.<br />

Evidence was at hand that certain longterm<br />

changes in oceanographic<br />

conditions were associated with<br />

changes in the faunal and floral distribution<br />

over the oceans. For instance, it<br />

was reported that the distribution and<br />

abundance <strong>of</strong> sardine in the Far East had<br />

been influenced, on at least four occasions,<br />

by abnormal changes in<br />

oceanographic or meteorological conditions,<br />

Similarly, the amelioration [sic] <strong>of</strong><br />

the subarctic climate in the last 25 or 30<br />

years (or longer) had resulted in the<br />

northward extension <strong>of</strong> a great many<br />

organisms. The changes in distribution,<br />

density and spawning area <strong>of</strong> cod were<br />

particularly striking. During the period <strong>of</strong><br />

weather amelioration, the catch on the<br />

west coast <strong>of</strong> Greenland had increased<br />

by a factor <strong>of</strong> about 30 and the area <strong>of</strong><br />

the greatest density moved some<br />

480 km to the north.<br />

In order to gain more knowledge on the<br />

bioclimatology <strong>of</strong> fisheries, the Council<br />

recommended that the first Fisheries<br />

Year for the Indo-Pacific area should be<br />

held during the International<br />

Geophysical Year 1957-1958 so that<br />

biological, fishery and geophysical data<br />

could be collected at the same time.<br />

In his presentation on the role <strong>of</strong> <strong>WMO</strong><br />

in providing weather information for fisheries,<br />

the <strong>WMO</strong> observer stressed the<br />

significance <strong>of</strong> weather to the fishing<br />

industry and assured the fullest cooperation<br />

<strong>of</strong> <strong>WMO</strong> in supplying weather<br />

information designed to promote safety<br />

in fishing operations. Member governments<br />

should be informed <strong>of</strong> the<br />

facilities provided by <strong>WMO</strong> and <strong>of</strong> the<br />

desirability <strong>of</strong> equipping their fishing<br />

fleets for reception and transmission <strong>of</strong><br />

meteorological data.

Price: £70/US$ 120.<br />

This book will be very useful, especially<br />

for graduate students in the<br />

areas <strong>of</strong> physical oceanography and <strong>of</strong><br />

numerical modelling applied to<br />

oceanography, generally. The organization<br />

<strong>of</strong> the seven chapters is logical;<br />

the proposed methods are presented<br />

after a good theoretical introduction,<br />

making it easy for the reader to find<br />

themes <strong>of</strong> interest.<br />

The numeration <strong>of</strong> formulas guides<br />

the reader through the basic formulation,<br />

the assumptions and the theory<br />

to gain a better understanding <strong>of</strong><br />

the methods that are explained in<br />

the book.<br />

The introduction in the first chapter<br />

gives the elements <strong>of</strong> the theory and<br />

formulas that are used in the following<br />

chapters. In this way, those who<br />

are not familiar with governing equations<br />

and linear wave equations may<br />

acquire the notions to understand better<br />

the formulation <strong>of</strong> the non-linear<br />

wave problem and the theory<br />

explained throughout the book.<br />

The second chapter explains linear<br />

baroclinic tides, then the numerical<br />

model, and the authors make an<br />

analysis <strong>of</strong> the formulation used for<br />

the different situations to which it can<br />

be applied. The internal wave generation<br />

theory is well described.<br />

The third chapter introduces a semianalytical<br />

two-layer model for internal<br />

waves, explaining the theory and<br />

describing the necessary equations.<br />

This makes it easier to understand the<br />

theory presented in the fourth chapter,<br />

where the analytical model<br />

approach changes to the numerical<br />

model approach.<br />

The fifth chapter describes the generation<br />

<strong>of</strong> internal waves by baroclinic<br />

tides and the models to analyse them.<br />

In view <strong>of</strong> the different uses to which<br />

data obtained from measurements<br />

and those from models are put, the<br />

chapter also explains the origin <strong>of</strong> the<br />

formulas used to explain the characteristics<br />

<strong>of</strong> the different types <strong>of</strong><br />

waves generated. This allows a better<br />

understanding <strong>of</strong> the theory proposed<br />

for the analysis <strong>of</strong> the different types<br />

<strong>of</strong> waves studied.<br />

The sixth chapter compares the data<br />

obtained from measurements and the<br />

results <strong>of</strong> experiments and makes an<br />

analysis <strong>of</strong> the effects and influences<br />

<strong>of</strong> the different characteristics that can<br />

be applied for the theory that is<br />

explained. Finally, the authors make a<br />

summary <strong>of</strong> the generation mechanism<br />

<strong>of</strong> baroclinic tides which helps<br />

the reader to a better understanding <strong>of</strong><br />

the waves generated under the different<br />

regimes and what is the approach<br />

that can be used for each <strong>of</strong> them.<br />

The last chapter explains the threedimensional<br />

effects <strong>of</strong> baroclinic tides<br />

for specific cases, using observed<br />

data for the analysis. This is really useful,<br />

because it gives the reader good<br />

tools to analyse the data that can be<br />

obtained from our own measurements<br />

and to establish different casestudies.<br />

Encyclopedia <strong>of</strong> Weather and<br />

Climate.<br />

Michael Allaby. Facts on File, New<br />

York (2002). ISBN 0-8160-4071-0<br />

(two volumes). Price: US$ 150.<br />

Michael Allaby undoubtedly enjoys<br />

the physical sciences and this comes<br />

through in his two-volume Encyclopedia<br />

<strong>of</strong> Weather and Climate. The<br />

title is a misnomer, however,<br />

because it describes more than just<br />

weather and climate. The encyclopedia<br />

contains explanations <strong>of</strong> the various<br />

physical, synoptic and thermodynamic<br />

processes that produce<br />

weather and climate in a concise but<br />

straightforward manner. It provides<br />

classifications <strong>of</strong> the various climates<br />

and descriptions <strong>of</strong> significant<br />

palaeoclimatic regimes. The important<br />

scientific concepts are written in<br />

a format that is easy to understand.<br />

It is not written for the physical scientist<br />

and therefore the author limits<br />

his use <strong>of</strong> equations. The layman will<br />

find the encyclopedia quite useful.<br />

The various meteorological and<br />

oceanographic terms are well<br />

143


144<br />

defined. The definitions are supplemented<br />

by effective maps, charts<br />

and schematic diagrams. There are<br />

over 4 000 entries in the two volumes,<br />

which include explanations <strong>of</strong><br />

the impacts <strong>of</strong> climate on ecology<br />

and human health. These elements<br />

make the encyclopedia a welcome<br />

addition to the meteorological library<br />

and as a good reference for the general<br />

public.<br />

Even the pr<strong>of</strong>essional meteorologist<br />

will find the volumes useful. Explanations<br />

<strong>of</strong> terms that may only be used<br />

in particular locations are included.<br />

The meaning <strong>of</strong> contrastes—a local<br />

wind in the Mediterranean—is<br />

included, for example.<br />

Those who require information on<br />

international climatological or meteorological<br />

activities, projects and programmes<br />

will not be disappointed.<br />

The Cooperative Holocene Mapping<br />

Project is described and references to<br />

Websites for more information are<br />

provided. This is available throughout<br />

both volumes.<br />

Climate change has now entered the<br />

vernacular <strong>of</strong> the news and everyday<br />

life. Important information on this<br />

topic can also be found in the encyclopedia.<br />

The meaning <strong>of</strong> terms such as<br />

the clean development mechanism<br />

(CDM) is included.<br />

However, the encyclopedia goes<br />

beyond that. It provides interesting<br />

historical narratives such as a description<br />

<strong>of</strong> the formation <strong>of</strong> the United<br />

States Weather Bureau. It also provides<br />

biographical information on<br />

important historical figures in <strong>meteorology</strong><br />

such as Daniel Fahrenheit, the<br />

developer <strong>of</strong> the Fahrenheit temperature<br />

scale. Photographs and sketches<br />

<strong>of</strong> some <strong>of</strong> these figures are included.<br />

In addition, the encyclopedia is liberally<br />

interspersed with anecdotes such<br />

as the use <strong>of</strong> conditions on Christmas<br />

Day to predict the weather months in<br />

advance.<br />

The author has also tried to include<br />

significant weather events. These<br />

include various tropical cyclones that<br />

have affected nations around the<br />

world. Naturally, every tropical<br />

cyclone that had significant impacts<br />

on all locations could not be included.<br />

There were bound to be major omissions.<br />

Readers will therefore be disappointed<br />

when a system that they<br />

expected to find is not included.<br />

Earth science information is also<br />

included. The reader will therefore be<br />

able to find information on volcanoes<br />

and other geological phenomena.<br />

The encyclopedia ends with five<br />

appendices that include chronologies<br />

<strong>of</strong> disasters and discoveries, geological<br />

timescales, important Websites<br />

and an index.<br />

National Meteorological and Hydrological<br />

Services (NMHS) continue to<br />

be the resource <strong>of</strong> first choice for<br />

the general public concerning physical<br />

phenomena especially in developing<br />

countries. This small set <strong>of</strong><br />

encyclopedias can serve as an<br />

important resource for those who<br />

have to respond quickly to requests<br />

from the public, students and teachers.<br />

The terms are placed logically<br />

and effectively cross-referenced.<br />

Material is therefore easy to find.<br />

The concise, but straightforward<br />

entries can be used to provide simple<br />

explanations. Junior members <strong>of</strong><br />

staff can use the information to<br />

become attuned to activities occurring<br />

on the periphery <strong>of</strong> their immediate<br />

duties and responsibilities, and<br />

even senior members <strong>of</strong> staff can<br />

use it as a resource for unfamiliar<br />

terms. I would therefore recommend<br />

it as an addition to the meteorological<br />

library or a handy reference for<br />

the on duty meteorologist in a small<br />

Service.<br />

(ozone@btl.net)<br />

The book consists <strong>of</strong> five parts. It<br />

starts with a brief history <strong>of</strong> the discovery<br />

and evolution <strong>of</strong> the topic<br />

treated over a period <strong>of</strong> about<br />

30 years to specialized aspects that<br />

include the geochemistry <strong>of</strong> the<br />

processes <strong>of</strong> reaction and mechanisms<br />

<strong>of</strong> <strong>transport</strong> <strong>of</strong> the fluid flows,<br />

through the different structures <strong>of</strong> the<br />

oceanic crust, including the nature,<br />

state and properties <strong>of</strong> the means in<br />

which these flows are developed.<br />

Part III is a quantitative analysis <strong>of</strong> the<br />

treated parameters <strong>of</strong> heat and fluid<br />

flow. The five parts contain 21 articles<br />

written by scientists <strong>of</strong> different<br />

research organisms and <strong>of</strong> varied<br />

experience in the subject.<br />

The review presented here centres on<br />

the general context <strong>of</strong> the book, its<br />

form and structure, the scientific<br />

base, and the form <strong>of</strong> its presentation,<br />

language and style; as well as the correlations<br />

between the theories and<br />

the diagrams.<br />

Several specialists who participated in<br />

a workshop supported by the International<br />

Lithosphere Program and the<br />

Joint Oceanographic Institutions/US<br />

Science Support Program decided to<br />

present the results <strong>of</strong> their studies in<br />

diverse disciplines (physics, chem-


istry, and microbiology). The subject is<br />

becoming increasingly important,<br />

especially for students and<br />

researchers in the Earth sciences and<br />

oceanography. The contents are written<br />

in clear, explanatory language.<br />

The information provided in each article<br />

is adapted, coherent and up to<br />

date. The book is a good tool for<br />

researchers who wish to correlate<br />

diverse parameters and results in different<br />

environments. A wide range <strong>of</strong><br />

different subjects is treated, from the<br />

properties <strong>of</strong> the materials <strong>of</strong> the<br />

oceanic crust generated during the<br />

cortical accretion, to the methodologies<br />

used and suggested for improved<br />

acquisition <strong>of</strong> the results (nature,<br />

causes and consequences).<br />

An important aspect <strong>of</strong> the book is the<br />

presence <strong>of</strong> an ample preface and<br />

explained objectives. The content, terminology,<br />

and perspectives <strong>of</strong> the<br />

subject and the clarity <strong>of</strong> the presentation<br />

make the book useful.<br />

Another important aspect is the clear<br />

presentation <strong>of</strong> ideas and use <strong>of</strong> new<br />

tools, including the shore-to-ship connection.<br />

It may become questionable<br />

and difficult to bridge the different disciplines<br />

in order to be able to better<br />

understand the dynamics <strong>of</strong> the<br />

planet.<br />

The subject dealt with has recently<br />

become an interesting one for those<br />

countries with seismic activity. In the<br />

case <strong>of</strong> Ecuador, for example, measurements<br />

<strong>of</strong> heat flow were made in<br />

the marine campaign Amadeus, 2005.<br />

The experience developed throughout<br />

the years has allowed us to define key<br />

elements for the understanding and<br />

quantification <strong>of</strong> the rates <strong>of</strong> change<br />

<strong>of</strong> flows between the crust and overlying<br />

oceans—elements that are now<br />

clearly understood and better visualized.<br />

The book describes work on one<br />

<strong>of</strong> the most widely distributed and volumetrically<br />

important: ridge flanks.<br />

The subject is not only <strong>of</strong> scientific<br />

but also <strong>of</strong> economical interest<br />

because <strong>of</strong> the relations between different<br />

types <strong>of</strong> flows and mineralogical<br />

elements. While the editors do not<br />

try to answer all the questions that<br />

could be raised, the desire to contribute<br />

to enhanced knowledge <strong>of</strong> the<br />

subject is demonstrated.<br />

A remark concerns the part about<br />

geochemical fluxes. It would have<br />

been better to interchange Chapters<br />

19 and 21 so as to present the topic<br />

from a global context to a more specific<br />

one, which is the fundamental<br />

subject <strong>of</strong> the book.<br />

The book carries an interactive accompanying<br />

CD-ROM with a full set <strong>of</strong> diagrams,<br />

captions, references and photos<br />

<strong>of</strong> research vessels, submersibles,<br />

and other tools used in hydrological<br />

studies.<br />

To summarize, the vast experience <strong>of</strong><br />

the specialists who contributed to the<br />

writing <strong>of</strong> this volume, makes this<br />

work, a valuable resource in the sciences<br />

<strong>of</strong> the Earth and the sea.<br />

This book is a significant contribution<br />

to the history <strong>of</strong> international marine<br />

scientific organizations. It presents the<br />

process <strong>of</strong> creating the North Pacific<br />

Marine Science Organization (PICES).<br />

It seems obvious enough that such an<br />

organization was needed—the best<br />

way for the Pacific Rim nations to gain<br />

knowledge about the enormous North<br />

Pacific Ocean is through cooperative<br />

research—yet PICES was two<br />

decades in the making.<br />

The reasons for this lengthy incubation<br />

are described. The process took<br />

promotion, patience, and perseverance.<br />

Today, PICES is an active sixnation<br />

international marine organization,<br />

This IPCC Technology and Economic<br />

information relevant to decisionmaking<br />

in regard to safeguarding the<br />

ozone layer and the climate system.<br />

Scientific evidence linking chlor<strong>of</strong>luo-<br />

rocarbons and other ozone-depleting<br />

substances (ODSs) led to the initial<br />

control <strong>of</strong> chemicals under the 1987<br />

Montreal Protocol and to amendments<br />

and adjustments in the 1990s.<br />

As various approaches to the phaseout<br />

<strong>of</strong> ODSs were developed it was<br />

realized that some actions taken to<br />

reduce future depletion <strong>of</strong> the ozone<br />

layer, in particular the introduction <strong>of</strong><br />

HFCs and PFCs, could affect global<br />

warming.<br />

This report provides the scientific context<br />

required for consideration <strong>of</strong><br />

choices among alternatives to ODSs;<br />

potential methodologies for assessing<br />

options; and technical issues relating<br />

to greenhouse-gas emission-reduction<br />

Earth’s climate is changing, with the<br />

global temperature now rising at a<br />

rate unprecedented in the experience<br />

<strong>of</strong> modern human society. These climate<br />

changes, including increases in<br />

ultraviolet radiation, are being experienced<br />

particularly intensely in the Arctic.<br />

Because the Arctic plays a special<br />

role in global climate, these changes<br />

in the Arctic will also affect the rest <strong>of</strong><br />

the world. It is thus essential that<br />

decision-makers have the latest and<br />

best information available regarding<br />

ongoing changes in the Arctic and<br />

their global implications.


The Arctic Council called for this<br />

assessment and charged two <strong>of</strong> its<br />

working groups, the Arctic Monitoring<br />

and Assessment Programme (AMAP)<br />

and the Conversation and the Conservation<br />

<strong>of</strong> Arctic Flora and Fauna<br />

(CAFF), along with the International<br />

Arctic Science Committee (IASC),<br />

with the responsibility for scientific<br />

oversight and coordination <strong>of</strong> all work<br />

related to the preparation <strong>of</strong> the<br />

assessment reports.<br />

Cape Town, South Africa, February 2006 — Participants in the THORPEX Scientific<br />

Conference: Improving the Global Predictability <strong>of</strong> High Impact Weather<br />

lar, the South African Weather Service<br />

is an active contributor to CAS<br />

and operates the Cape Point Global<br />

Atmospheric Watch (station. The<br />

Secretary-General visited this station<br />

and also inaugurated the establishment<br />

<strong>of</strong> the THORPEX Southern<br />

France<br />

On 23 February 2006, the Secretary-General<br />

visited Paris to participate<br />

in a conference and debate<br />

organized by the Scientific Council<br />

<strong>of</strong> the French Association for the<br />

Prevention <strong>of</strong> Natural Disasters<br />

(AFPCN). In the presence <strong>of</strong> HE Ms<br />

N. Olin, Minister <strong>of</strong> Ecology and<br />

Sustainable Development, and Senator<br />

Mr Y. Dauge, President <strong>of</strong><br />

AFPCN, Mr Jarraud presented the<br />

opening keynote speech to the conference,<br />

which was organized as a<br />

concerted attempt to interactively<br />

consolidate lessons learnt from the<br />

major natural disasters that had<br />

occurred, over the recent months,<br />

in different parts <strong>of</strong> the world.<br />

In his speech, the Secretary-General<br />

stressed that actions can<br />

indeed be taken to reduce considerably<br />

the loss <strong>of</strong> life and socio-economic<br />

damage caused by natural<br />

hazards, through the development<br />

and integration <strong>of</strong> risk knowledge<br />

and end-to-end multi-hazard early<br />

warning systems, as integral components<br />

<strong>of</strong> disaster-risk management<br />

activities. Thus, all the relevant<br />

technologies, expertise,<br />

capacities and experiences that<br />

were available had prevented many<br />

other natural hazards from becoming<br />

natural disasters.
