摘要

Daily precipitation data of the monsoon season during (1940-90) is presented. A test of significance at 5% level was carried out using Student 't' distribution. Stations, qualifying the significance test are considered here. As observed, flood occurs mainly due to the tropical disturbances, like monsoon depressions, cyclonic storms, low pressure systems (monsoon lows) passing from the neighboring seas i.e. Bay of Bengal and Arabian seas. Empirical Orthogonal Analysis (EOF) analysis was used to find out the nature of rainfall distribution patterns in flood years. This technique thus identifies the spatial and temporal patterns characteristics of possible physical significance.
