             abstract = "An important role of the South American Monsoon System (SAMS) is 
                         in driving the water balance in the tropics and subtropics by 
                         modulating the Tropical Atlantic Ocean's moisture flux that enters 
                         South America at its northern coast and is deviated southwardly by 
                         the Andes to end up contributing to subtropical precipitation. An 
                         yet open question is how this picture might be changed under the 
                         upcoming anthropogenic climate changes. We draw some light on the 
                         matter by comparing modeled moisture fluxes for the 20th and 21th 
                         centuries. The Brazilian Model of the Global Climate System 
                         (BMGCS), which is being developed by the Brazilian scientific 
                         community for its climate change studies and is known to reproduce 
                         the SAMS, is used for this study. Sea surface temperature (SST) 
                         fields from Hadley Center-HadCM3, GFDL-CM2.1 and MPI-ECHAM5 models 
                         produced on the 20C3M, A2 and B1 experiments are used to force the 
                         atmospheric component of BMGCS and downscale these IPCC scenarios. 
                         The vertically integrated moisture flux and the moisture balance 
                         over South America is analyzed here for each of our nine model 
                         integrations. Our results for the rainy season (NDJFM) season 
                         shows an intensification of the moisture flux crossing the 
                         continent, which is more strong under A2 scenario than under B1. 
                         This is in agreement with many studies that shown an 
                         intensification of the global hydrological cycle for a warmer 
                         climate and particularly those that points to increased 
                         precipitation in subtropical South America.",
