Abstract :

The fifth assessment report of IPCC (2013) categorically states that “warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The global circulation in terms of precipitation is an important element for the functionality of the Earth’s system. It helps to regulate the temperature of the Earth by transporting heat from the tropics to the higher latitudes. However, this system is vulnerable to long-term temperature fluctuations, more commonly termed as climate change. Climate variability and change continue to threaten the sustainability of water resources around the world. Increasing temperature is likely to modify the timing, form, and intensity of precipitation events, which will alter regional and hydrologic cycles. Since drought, water shortages, and subsequent water conflicts may become an increasing threat in many international watersheds, sustainable water resources planning is critical to cope with climate change.. All water storage structures are designed for a period of 30 years and it is utmost essential to predict the rainfall in the catchment area. Due to the changing climatic conditions the rainfall pattern is rapidly changing and the prediction of rainfall keeping in view of the climatic conditions is essential.. A prediction model can help in forecasting the rainfall pattern using statistical downscaling and regression analysis. The projections presented here could provide valuable information for risk management and climate adaptation planning in the study area. They can also be used to estimate relative change in the amount of precipitation received in monsoon season as compared with other seasons, which may be important for water resources management. The present study is carried out to predict rainfall in a newly formed district of the State of Maharashtra i.e. Palghar. The study area receives abundant rainfall, but due to poor management most of the precipitation is lost as runoff. Downscaling of meteorological parameters to local scale and thus prediction model is prepared for prediction of precipitation using Multiple Linear Regression for a projected future. Thus by accessing the future rainfall pattern, we can reduce the risk of water crisis and utilize the same in efficient water resource planning.
