ONSET OF THE RAINY SEASON OVER TROPICAL BRAZIL IN OBSERVATIONS AND A GENERAL CIRCULATION MODEL SIMULATION

Liebmann, B.; Allured, D.; Camargo, S.J.

The intent of this paper is to present and document the hypothesis that the influence of sea surface temperature (SST) on rainfall in tropical Brazil is largely through its influence on onset and end of the rainy season, rather than on rain rates during the rainy season itself. The observations are compared with one 50 year run of the Euro- pean Centre / Hamburg Atmospheric Model ver- sion 4.5 general circulation model (GCM), although in this abstract, although only the obser- vations are shown.
