AbstractThe characteristics of the persistent wet and dry events over south of Brazil during all seasons are examined. The dataset used in this study include daily precipitations totals from several stations in the period 1979-2002, from the Agência Nacional de Energia Elétrica (Aneel). The gauge stations are uniformly distributed over the three states of South of Brazil. The atmospheric circulation is analyzed using the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) reanalysis. From the precipitation data were selected 88 dry and 97 wet events. Composite charts based on these selected wet and dry events reveal some common atmospheric processes and circulation features according to the season. Basically, more precipitation over south of Brazil is accompanied by less precipitation to the Southeast of Brazil. The vertically integrated horizontal water vapor flux for the wet events shows convergence over south of Brazil associated with a decrease in the northwestern flux intensify and with the curvature of the anticyclonic circulation anomaly whose center is located over South Atlantic Ocean. For the dry events exist a divergence over south of Brazil associated with an intense southern flow. A significant precursor to wet events, is the presence of an upper level cyclonic circulation anomaly over the southern South America, in all seasons, except summer. During summer, this anomaly is observed displaced to south, over the South Atlantic Ocean. For dry events, the composite pattern is nearly opposite. The upper levels meridional component anomaly composites exhibit a wavelike pattern for all events. For winter, the signal is typical of the zonal wavenumber 4 or 5. The wavelike path over the Pacific-American sector suggests the existence of a Rossby wave guide along the South Pacific jet and into the subtropics of the South Atlantic during all events. The wave energy propagates along a great-circle route, from Central South Pacific to southern South America, and turn to northward after cross the Andes. Composites also were created after a temporal filtering of the data by using a Lanczos digital filter. For the 06-12-pentads band (30-60-days), the signal, although weak, is wavelike and maintains the behavior observed in the non-filtered data.
