%X Rainfall variability in the northeast South America and in Africa's Sahel region is profoundly influenced by sea surface temperature (SST)anomalies. Ping Chang and Li (1997)proposed that decadal variations in the tropical SST dipole may be attributed to a thermodynamically unstable ocean-atmosphere interaction between wind-induced heat fluxes and SST anomalies. Within this framework the importance of the heat flux estimation through the tropical ocean surface becomes evident. The main objective of this study is to estimate each component of the heat budget equation (Equation 2)in the Pilot Research Moored Array in the Tropical Atlantic (PIRATA)region. In addition, the contribution of each heat component to the temperature tendency of the mixed layer is estimated.
