%X Normal rainfall events were associated, in the entire field of study, with sea surface temperature (SST) negative anomalies in situations of Front Cold, being that near the coast of southeastern Brazil (SEB), these anomalies were of the order of -0.3ˇăC in three days analyzed. However, in situations of South Atlantic Convergence Zone (SACZ) the normal rainfall events showed negative anomalies less intense, i.e. the order of -0.1ˇăC on the coast of SEB, and positive anomalies were present in the entire extension of the coast of Argentina, Uruguay, the states of Rio Grande do Sul and Paran¨˘. On the other hand, the heavy rainfall events in situations of SACZ showed a weakening of the anomalies during the days over SEB cost, whereas south of 30ˇăS these anomalies intensified with each passing day. Correlations confirmed what was seen in the analysis of anomalies composition, while the SST negative anomalies over the Subtropical South Atlantic and positive anomalies over the South Atlantic Extratropical appear to be associated with increased rainfall over the SEB.
