Abstract

This work analyzes changes, in space and time, of lightning and surface precipitation generated by a convective system occurred in Southeastern Brazil on October 2007. Satellite imagery from the GOES-10 infrared were used to identify and track the system, cloud-to-ground lightning data from RINDAT network and surface precipitation from automatic stations were also used. After its formation, this system evolved as a linear system, then turned into a quasi circular system to, after a new transition, get into the dissipation process. Each transition phase presented unique features in the evolution of lightning and precipitation. Most cloud-to-ground lightning were negative, tending to be grouped as a cluster, while the positive occurred in a more scattered way.
