                         The annual frequency of the heavy and extreme rainfall events is 
                         obtained for the southeastern and southern Brazil regions. In the 
                         1960-2004 period, 510 (98) and 466 (77) heavy (extreme) rainfall 
                         events are identified in the two regions. Monthly distributions of 
                         the events closely follow the monthly climatological rainfall in 
                         the two regions. In both regions, annual heavy and extreme 
                         rainfall event frequencies present increasing trends in the 45-yr 
                         period. However, only in southern Brazil is the trend 
                         statistically significant. Although longer time series are 
                         necessary to ensure the existence of long-term trends, the 
                         positive trends are somewhat alarming since they indicate that 
                         climate changes, in terms of rainfall regimes, are possibly under
