National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow analysis. Annually, the increase in magnitude was 1.04 mm per year over entire Haryana. On the seasonally scale, increase in magnitude was 0.05 mm per year for premonsoon season and 0.19 mm per year for monsoon season. CLIMATE CHANGE AFFECT ON SW AND NE- MONSOON SEASONS OF INDIA Indira Sudhir Joshi Indian Institute of Tropical Meteorology, Dr.HomiBhabha Road, Pashan, Pune-8(M.H.) Scientists are investigating the anticipated effects of climate change on India's Monsoon Season and the impact that alterations in India's water cycle will have on the country’s people, agriculture and wildlife. Changes to India's annual monsoon are expected to result in parts of India in severe droughts and intense flooding. Scientists predict that by the end of the century the country will experience a 3 to 5°C temperature increase and a 20% rise in all summer monsoon rainfall. The livelihood of a vast population in India depends on agriculture, forestry, wetlands and fisheries and land use in these areas is strongly influenced by water-based ecosystems that depend on monsoon rains. Changes to the water cycle may also cause an increase in water borne diseases such as cholera and hepatitis, as well as diseases carried by insects such as malaria. The increasing failure of the monsoon has been attributed to a number of factors including temperatures rising by an average on 0.5 degrees Celsius over the last hundred years, receding Himalayan glaciers and rising sea levels. Keeping the above in view a study has been undertaken to investigate the effects of climate change on cyclonic storms and depressions forming over Bay of Bengal and Arabian Sea. HEAT WAVE CONDITIONS OVER INDIA DURING 1961- 2010 Smitha Anil Nair, D.S. Pai and A.N. Ramanathan India Meteorological Department, Pune. Using heat wave information of 104 stations from Indian main land during the hot weather season (March to July) various aspects of heat waves such as its long term climatology, decadal variation and trends over India were examined. For deriving information regarding heat wave, daily maximum temperature data over these stations 80
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow for the last 50 years (1961-2010) were used. The daily maximum temperature data for the period 1969-2010 were obtained from National Data Center, India Meteorological Department, Pune and data for the period 1961-1968 were derived from daily Indian Daily Weather Report logs published by India Meteorological Department. It was observed that the stations from the northwest Rajasthan and neighboring Punjab, north M. P and coastal Andhra Pradesh experienced more than 700 days of heat wave days during the data period 1961-2010. Also stations from Uttaranchal, east Uttar Pradesh, Bihar, and Orissa experienced more than 60 severe heat wave days during the data period of 1961 – 2010. Among the 104 stations used here, Nellore has experienced maximum number of heat wave days (1646) during the entire period followed by Ganganagar (830), Chennai (781) and Jhansi (769). Ganganagar, Hissar, Bhubaneswar showed consistently increasing trend of heat wave across all the decades. In the case of severe heat wave days, Dehradun experienced the maximum number of severe heat wave days (82), followed by Bahraich (64), Purnea (63) and Balasore (62). The maximum number of heat wave days was observed in the month of May and maximum number of severe heat wave days was observed in the month of June. The decade 2001- 2010 experienced the maximum heat wave spells. The year 2010 had the maximum number of both heat wave and severe heat wave days. There is a significant increase in the spatial coverage of heat wave and severe heat wave during the decade 2001 – 2010 compared to the previous decade. The results of trend analysis show evidence of an increasing trend in heat wave days over India during 1961-2010 with more than 50% stations showing statistically significant increasing trend. It can be concluded that the observed increasing trend in the heat waves in India is in tune with the observed global warming.
