Abstract
The AMMA-CATCH Benin site situated in the Upper Oueme Region has been equipped with a dense network of rain gages since 1997, covering an area of about 10 000 km2. During the AMMA EOP and SOP campaign, complementary measurements of the rainy systems were made with radars and disdrometers. The analysis of these complementary data sets highlights the variety of MCS that crosse the Oueme Basin. The dominant type of rainy event vary within the season, with the best organized and faster propagating systems occuring early, as in June, while less organized afternoon convection is more present at the peak of the season in July or August. The 2D structure of the rain field and the microstructure of rain vary also from storm to storm and between the convective and stratiform regions of the rainy events. The link of these characteristics with the larger scale properties of the systems as tracked by satellites, and their consequences on rainfall estimation will be discussed.
