VARIABILITE SPATIO-TEMPORELLE DU CYCLE DIURNE DE LA CONVECTION EN AMAZONIE.

Abstract : We examine the diurnal cycle of precipitation and convection in the Amazon region, particularly in the state of Mato Grosso, Brasil, where changes in land use and forest cover have been dynamical in the last decades. We consider the years 2004 to 2006, which encompass a period of severe drought (2005) that affected several parts of Amazon, and had a significant socio-economical impact. We use mainly satellite data from the Advanced Microwave Sounding Unit (AMSU) and the Tropical Rainfall Measuring Mission (TRMM) to detect and characterize convective activity. This study aims at a better representation of the variability of convective activity in the Amazon basin, and may also contribute to e.g. validation of regional climate models.
