%B International Conference on Southern Hemisphere Meteorology and Oceanography, 6.
%X Many studies have already indicated that the precipitation pattern over South America, in particular over some regions in Brazil, is strongly influenced by the extremes of the Southern Oscillation (SO) (Ropelewski e Halpert, 1987; and Rao e hada, 1990). Coelho et al. (1999), using datasets from 206 meteorological sations over Brazil, have developed a seasonal climatologica precipitation study for El Niño/La Niña episodes, classifying them as strong/moderate or weak. For each season, different characteristics of the precipitation pattern were found. These results are in agreement with the present one. Using seasonal and monthly rainfall anomalies and Outgoing Longwave Radiation (OLR) data for the austral summer (December-January-February) during the El Niño events of 1982/83, 1986/87 and 1991/92, and the La Niña events of 1984/85, 1985/86 and 1988/89, and analysis of the lower and upper level circulation, the associated convection and rainfall features were made. We will show here seasonal anomalies composites of these ENSO events. Rainfall observations from 2138 meteorological stations over South America are used, with few of them going back in time from 1853 to 1996. The precipitation dataset implemented by Xie and Arkin (1996) for the period 1979 to 1955 is also used in this study, together with the NOAA OLR, and the (NCEP/NCAR) Reanalysis data, for the period 1968 - 1996.
