                         evaluated for two contrasting 5-year periods, 1985-1989 (wet) and 
                         1990-1994 (dry), of rainfall over Northeast Brazil (NEB) using 
                         NCEP/NCAR reanalysis data. The linear correlation coefficients 
                         between the 5-year averages of rainfall over NEB and sea surface 
                         temperature (SST) anomalies over the Atlantic Ocean show a dipole 
                         configuration over the Tropical Atlantic. It is found that 
                         evaporation is higher over the Tropical North Atlantic, and lower 
                         over the Tropical South Atlantic during the 5-year period of 
                         higher rainfall over NEB. Higher evaporation causes lower SST and 
                         vice versa. This seems to be the main mechanism which generates 
                         dipole configuration in the Atlantic SST. During the rainy season 
                         (February through May) in NEB moisture is transported towards NEB 
                         and converges, providing the necessary moisture source for the 
                         rainfall. This low level convergence is associated with the rising 
                         branch of a local meridional circulation cell, which in turn is 
                         generated by the SST dipole. This series of interlinked mechanisms 
                         seems to fit in a physical picture responsible for the rainfall 
                         decadal variation over NEB.",
