                         An analysis in the monthly departure of the relative vorticily 
                         field ([zeta]') over the globe and monthly departures of the sea 
                         surface temperature (SST) in the Tropical Atlantic Ocean is 
                         performed for years of droughts and floods over Northeast Brazil, 
                         in the period from 1963 to 1980. Planetary scale wavelike patterns 
                         were observed in the [zeta]' field, similar to those found in 
                         previous theoritical and observational studies. Of major interest, 
                         it is the phase coherence of the wavelike patterns of circulation 
                         anomalies over the Northern Hemisphere and the precipitation 
                         regime over Northeast Brazil. Such phase coherence, in addition to 
                         the occorrence of SST anomalies in the Tropical Atlantic Ocean 
                         (with warver waters in the north and colder in the south of the 
                         equator for drought years, and the reverse for flood years), 
                         indicates that the existence of global scale wavelike patterns in 
                         [zeta]' field, as well as the variability of the precipitation 
                         regime over Northeast Brazil are, respectively, the remote and 
                         local response of the atmosphere to a tropical thermal forcing.",
