                         four main indices: PRCPTOT - total precipitation; Rmm - number of

                         SDII - simple precipitation intensity index. The study used data 
                         for 12 hydrographic basins from 1975 to 2005. The seasonal 
                         distribution of these precipitation indices in Brazil is 
                         summarized concerning the main atmospheric systems acting in South 
                         America. The austral summer and autumn present the maximum 
                         PRCPTOT, Rmm, and Rx1day, related to the South American Monsoon 
                         System and Intertropical Convergence Zone. However, in the winter, 
                         the extreme northern and eastern coast also present high Rx1day.

                         southwestern Brazil, related to mesoscale convective complexes.
