                         desvios superiores a 70%. No outono, os desvios variaram entre 50%

                         evaluate the rainfall seasonal variability in southern Brazil 
                         between 1988 and 2007, from the standard deviation calculation. 
                         For this, we used data from rain gauges from National Water Agency 
                         database and rainfall estimates from Tropical Rainfall Measuring 
                         Mission satellite (TRMM), 3B43 algorithm. The results show that, 
                         in summer, the smallest rainfall deviations were observed in the 
                         east of Santa Catarina (SC) and east-central of Paran{\'a} (PR) 
                         states, where values were below 40%; while the southwest of Rio 
                         Grande do Sul (RS) presented deviations above 70%. In the fall, 
                         the deviations ranged between 50% and 60% in most of the region. 
                         In winter, the smallest deviations were located in east-central of 
                         RS state, and in the central portion of SC, ranging between 35% 
                         and 50%; while the highest deviations were recorded in the south 
                         and west of RS, and in the extreme north of PR, where the 
                         deviations exceeded 80%. In spring, the areas with the smallest 
                         deviations were located in western of SC, with percentages below 
                         40%, while the highest values were observed in most of RS state 
                         and in the extreme north of PR.",
