摘要

Extreme meteorological and hydrological events have huge impacts on human society. From these events, rainfall is a phenomena, which directly or indirectly affects all the sectors like agriculture, insurance, industry and other allied fields. This paper deals with the maximum likelihood estimates of parameters for exponential family like Generalized Extreme Value distribution and Gamma family for capturing the frequency trend of yearly seasonal cumulative rainfall of India from the period 1813-2001. Finally, Generalized Extreme value model (GEV) is found as the best-fitted distribution model because it fully satisfied all the statistical assumptions (K-S Goodness of fit and Q-Q plot), which are adopted under the present study. The return levels are also estimated for 2, 5, 10, 50, 100 and 200 years, which are consistently increasing for long run in future.
