Abstract :
This paper presents results from the statistical analysis of extreme events of rainfall induced attenuation and measured rainfall rate in 4 sites in Brazil. The extreme values of attenuation and rainfall are obtained form the time series of measured data on a daily basis. Distribution functions of extreme attenuation and rainfall values were tested against 2 extreme value distributions and, in the case of rainfall, the lognormal. Both extreme values of attenuation and rainfall were found to follow a Weibull distribution.
