The large scale heat and moisture budgets are studied during a SACZ and Bolivian High Episode for a NCEP analyses and CPTEC Global Model forecasts. It is analyzed the predominant components and interpreted the heat and moisture sources and sinks based on residuals. The results indicate that the vertical advection terms play an important contribuation to the residuals specially in the regions with intense convective activity. The best performance of CPTEC Global Model is obtained in the 24, 48 and 72 hours forecasts.Pages: 3646-365
