<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 />

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 />
engineering, water-quality monitoring,<br />
protection <strong>of</strong> coral reefs and other<br />

control within the coastal zone<br />

planning guidelines. Meteorological<br />
observations and technology are in the<br />
areas <strong>of</strong> coastal engineering and marine<br />
biology.<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 />
was undertaken to support the<br />
coastal analysis and design process for<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 />
Baird 2005)<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 />

model was employed to simulate<br />
the transformation process in order<br />
to determine wave conditions at<br />
specific project sites;<br />
Analysis <strong>of</strong> waves generated by<br />
tropical cyclones: several different<br />
tasks were carried out to address<br />
hurricane-induced wave conditions<br />
at Barbados:<br />
– Analysis <strong>of</strong> historical hurricane data;<br />
– Numerical simulation <strong>of</strong> waves<br />
generated by historical tropical<br />
cyclones 1981-2000. The results<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 />
87

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 />

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 />

prevention <strong>of</strong> marine pollution. The<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 />
MSI free <strong>of</strong> charge to all shipping regulated<br />
by the Convention (all passenger<br />
vessels and all cargo ships <strong>of</strong><br />
300 gross tonnage and upwards on<br />
international voyages).<br />

Ship distress and safety communications<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 />
97
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 />

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 />

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 />
Nowcast/forecast<br />
Many operations are safeguarded<br />
by on-site measuring devices, such<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 />

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 />

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 />

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 />
Africa.<br />
A First <strong>WMO</strong>/Intergovernmental<br />
Oceanographic Commission (IOC-<br />

Meeting for a Western Indian Ocean<br />
Marine <strong>Applications</strong> Project<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 />
for the benefit <strong>of</strong> a diversity <strong>of</strong><br />
national, regional and global users;<br />
and<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 />
(Photo: FAO/<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 />
Capture its elements for productive<br />
purposes<br />
Minimize its adverse impacts on<br />
societies and ecosystems<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 />
The following aspects <strong>of</strong> climate are<br />
<strong>of</strong> concern to the atmospheric science<br />
community:<br />
Climatology<br />
Climate variability<br />
– Seasonal-to-interannual<br />
Climate fluctuations<br />
– Decadal scale<br />
Climate change<br />

Seasonality<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 />
have relatively ideal climates and environments<br />
(at least ideal compared to<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 />
121
122<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 />
westward from the Bay <strong>of</strong> Bengal;<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 />

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 />

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 />

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 />

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 />
and the Wei basins, affecting<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 />

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.

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 />

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 />

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.

delivers a lecture on the structure <strong>of</strong> hurricanes<br />
during the first international seminar on<br />
hurricanes (Ciudad Trujillo, Dominican Republic,<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 />

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.

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 />
National Hydrological and Meteorological<br />
Service.<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 />
contributing substantially to<br />
marine science.<br />

This IPCC Technology and Economic<br />
Assessment Panel Special Report provides<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 />
opportunities for each <strong>of</strong> the sectors<br />
involved.<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 />

Kirill Kondratyev<br />
Kirill Kondratyev died on 1 May 2006.<br />
He was a famous scientist, a full<br />
Academician <strong>of</strong> the Russian Academy<br />
<strong>of</strong> Sciences and an acknowledged<br />
expert in the area <strong>of</strong> climate<br />
and the environment. He was<br />
the author <strong>of</strong> more than 1 000<br />
papers in prestigious journals, as<br />
well as more than 100 monographs<br />
and textbooks. Kondratyev<br />
was an honorary member <strong>of</strong> many<br />
meteorological societies and scientific<br />
academies worldwide. He was editor-in-chief<br />
<strong>of</strong> the Russian Journal<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.
