             abstract = "Interactions between the sea surface temperature (SST) over the 
                         South Atlantic Ocean ( 40 degreesS-Equador) and the South Atlantic 
                         Convergence Zone (SACZ) were studied through numerical experiments 
                         with an atmospheric general circulation model (AGCM) and an ocean 
                         general circulation model (OGCM). The AGCM experiments showed that 
                         warm SST anomalies over the South Atlantic tend to intensify the 
                         SACZ and shift it northward, while cool SST anomalies over the 
                         South Atlantic tend to weaken the SACZ. The OGCM experiments, on 
                         the other hand, showed that the intensification of the SACZ 
                         contributes to cool the underlying ocean through the reduction of 
                         incident shortwave solar radiation, causing the appearance of cold 
                         SST anomalies or the weakening of pre-existing warm SST anomalies. 
                         The most important finding in this work was the predominance of 
                         the cloud/shortwave - SST negative thermodynamic feedback between 
                         the atmosphere and the ocean over the southwest tropical Atlantic, 
                         this is one order of magnitude larger than the dynamic feedback 
                         associated with Ekman pumping. The latter was verified only during 
                         strong SACZ events. The results suggest that negative SST 
                         anomalies often observed underlying the SACZ represent an ocean 
                         response to atmospheric forcing.",
