The present research studies the frequency and magnitude of extreme rainfall years with high rainfall variability that characterizes the study area since the 1970s. The data concern the high rainfall (daily, monthly, seasonal and annual) of four (4) stations from ASCNA-Cotonou and covering the period 1941-2000. The use of descriptive statistics (mean, quartile, etc.) and the frequency analysis, were used to process data collected. The results indicate that extreme rainfall years (surplus and deficits) are alternated with no apparent periodicity. In addition, the extreme rainfall was more frequent during the 1971- 2000 series of thirty especially during the rainy season in comparison to the 1941-2000 series. [ABSTRACT FROM AUTHOR]
