Abstract

Mean and maximum rainfall associated with cyclonic storms of the Bay of Bengal striking the two sections of the east coast of India are studied by examining the rainfall distributions along the coast on both sides of a point (P) at which the storms struck the coast at a right angle during the period 1877–1980. The distributions are presented for mean and maximum rainfall recorded during the 24 hours of the day of crossing and the previous two days. Extensive rainfall, of wavy pattern to the north of P and intensive rainfall to the south of P are observed. Possible reasons for these are given. Rainfall recorded within 1° on either side of P associated with each storm has been examined from the viewpoint of suitability of a statistical model. The distribution is highly skewed. The gamma distribution, which covers a wide range of skewness, has been tried. It is seen that a gamma probability model shows a good fit to the mean rainfall over this area. Variability of rainfall within a distance of 1° on either side of P is also studied and it is found that variability is more in the southern sector than in the northern sector.
