Resumo


The purpose of this article was to verify the existence of changes in the distribution and intensity of rainfall in four rainfall stations. The standard deviation and the trend were studied to understand the rain intensity along the series. The Kolmogorov-Smirnov test was applied to check if changes occur in the rain distribution over time. The standard deviation shows high variety in rainfall intensity during the whole 70 years series, but the trend indicates increase in the annual precipitation. The Kolmogorov-Smirnov test does not reject the hypothesis that all distributions studied are not different between them. Therefore, it is concluded that in the studied time series for each station there were no signifcant changes in the rainfall distribution, although the annual rainfall amount tends to increase.
