Statistical, Trend & Dry Spell Analysis of Point Rainfall for Parbhani

Indian agriculture is predominantly influenced by south-west monsoon rainfall (June to September), about 60 to 90 per cent of the annual rainfall over India is received from the southwest monsoon season which is vital for the agricultural economy of the country. Variation in rainfall distribution pattern is the major reason for increasing the probability of occurrence of drought like situation in the country. Analysis of rainfall trend is important in studying the impacts of climate change, water resources planning, drought, excessive rainfall and other environmental factors for the particular region. Knowledge of the sequences of dry and wet spells as well as onset and withdrawal of rainy season is necessary for successful planning and management of agricultural ecosystem. Hence, research work on “Statistical, Trend and Dry Spell Analysis of Point Rainfall for Parbhani” was conducted.
