%K MM5, extreme precipitation event, cumulus parametrization.
%X This work shows two simulations of an extreme event of precipitation occurred in October 1 SI, 2001 in the State of São Paulo, Brazil. The MM5 regional model was run with two schemes of cumulus parametrization: Anthes-Kuo and Grell. There were three nested grids, with 90, 30 and 10 Km of resolution. The Anthes-Kuo scheme was only applied for the mother domain, while for the other grids the Grell scheme was used. Accumulated precipitation fields every 3 hours were compared with satellite images and with 3 Km CAPPI accumulated for the same period. The qualitative comparison showed that the Anthes- Kuo scheme has a precipitation field closer to the observed than the Grell scheme. These conclusions are consistent with the literature. It was algo detected that both schemes underestimated the precipitation over the region of Grande São Paulo.
