Statistical modeling of monthly maximum rainfall in Senegal

Abstract

We provide the first statistical analysis of maximum rainfall in Senegal. The data are from twelve stations spread across Senegal. The generalized extreme value distribution was fitted to maximum rainfall by the method of maximum likelihood. Probability and quantile plots showed that the generalized extreme value distribution provided an adequate fit for all stations. The vast majority of stations do not exhibit significant trends in rainfall. Four of the stations exhibit positive trends in rainfall. Estimates of return levels are given.
