There is no decline in rainfall during 2011 so far in the country. The country received 716.0mm rain as a whole monsoon rainfall till 31st August 2011 is marginally higher than the seasonal quantum of 713.4mm.
Although, the rainfall quantum received for the country as a whole during the period 1st June – 10th August, 2011 was -4%, the decline was made up fully by the end of August 2011, due to the prevalence of active monsoon rainfall conditions.
Continuous R & D efforts are made to understand spatial and temporal variability of monsoon rainfall.
Due to the year-to-year variability and the associated within the season variability of monsoon rainfall, the areas of excess and deficient rainfall vary from year to year. Department has Launched a high-priority Programme to address the Science issues of Global and Regional Climate Change with a well equipped state-of-the-art Center for Climate Change Research (CCCR) at Indian Institute of Tropical Meteorology (IITM), Pune for inter-disciplinary research and training in the area of science of climate change. Prioritized R & D efforts are initiated to comprehensively understand the causes for the aforementioned changes in the southwest monsoon rainfall and to improve the rainfall predictions in all time scales.
