Abstract

The WRF(Weather Research and Forecastiong Model) is used to simulate Mesoscale Convective Systems occurred between 18-21 june 2014 close to ZF-2/LBA experimental site, Manuas, AM, Brazil. The main objective is to verify the convective parametrization Betts-MillerJanjic, a deep layer controled scheme, and Kain-Fritsch, a low level control scheme in simulations of tropical storms over the Amazon. The simulation least 72h with nested domains of 12 and 3 km. The evolution of convective systems, convective mode, cold pools and outdrafts were observed. The convective scheme Kain-Fritsch reproduced realistics storms with convective mode, propagation and downdrafts which resembles the usual observations.
