%K Amazon (region), raining systems.
%X This paper will present the main characteristics of the raining systems observed during the 2002 Dry-to-Wet field campaign in the Amazon region. This experiment was set during the pre-wet season in order to understand the transition between the dry to wet raining season and the impact of the aerosols produced by forest burning in the development of clouds. Weather radar, rain gauges, and lightning measurements are used to depict the main precipitation characteristics observed during this field campaign. Preliminary results indicate that Mescoscale Convective Systems (MCS) that propagated over the radar area are responsible for most of the total rain volume and lightning observations. Additionally, a persistent convective diurnal cycle was observed with local convection, and these convective clouds have raining cloud tops ranging from 12 to 18 km top. Some of these raining clouds presented lightning observation. Therefore, this study will try also to investigate the main differences observed during the formation of thunderstorms.
