                         contribution of the Sea Surface Temperature (SST) variations in: 
                         1) Brazil-Malvinas Confluence (BMC) region, 2) Southwest Atlantic 
                         Ocean and 3) Southern Brazil. Numerical simulations of the 
                         ECHAM5/MPI-OM coupled ocean-atmosphere model were used to analyze 
                         the changes in the seasonal trajectory of the extratropical 
                         cyclones, in terms of intensification of physical mechanisms and 
                         implications for future scenarios. The numerical experiment for 
                         the future scenario considered an atmospheric CO2 concentration of 
                         approximately 770 ppm, which represents an increment of more than 
                         350 ppm over the current values recorded by the Mauna Loa 
                         reference station. For this scenario, the results indicated a 
                         Storm Tracks (ST) displacement of 5\˚ latitude toward south 
                         and changes of the meridional transport of sensible heat, close to 
                         50\˚S. The increase in SST induces ST intensification and 
                         consequently an increase in the occurrence of extratropical 
                         cyclones. Overall, in the BMC region, we found a change in the 
                         pattern of cyclogenetic activity occurrence, with less frequent, 
                         but more intense events. On the Southern Brazilian region, the 
                         results of this study indicate increases in rainfall during summer 
                         months, whereas, a decrease in frequency and an increase in 
                         intensity were found for wintertime. We suggest that these changes 
                         could impact the climate dynamic of the Brazilian South coast, 
                         with a magnitude yet unknown.",
