             abstract = "Patterns of sea surface temperature (SST) anomalies over North 
                         Atlantic (Equator - 40ºN and 70ºW - 0º) are determined by 
                         Principal Components Analysis (PCA) to December-January-February 
                         (DJF) from 1979 to 2001. Association of these patterns with 
                         summertime convection over South America is determined by linear 
                         correlation between the time series of these patterns and Outgoing 
                         Longwave Radiation (OLR) anomalies over this continent. Coupled 
                         modes between North Atlantic SST anomalies and OLR anomalies over 
                         South America (40ºS-20ºN to 90ºW-20ºW) are determined by SVD also 
                         to DJF from 1979 to 2001. The spatial pattern associated with the 
                         first anomalies SST mode determined by (PCA) shows one monopolo 
                         pattern. The second pattern shows an out-of-phase relationship 
                         between SST anomalies over tropical and subtropical region. The 
                         third pattern shows three action centers over Atlantic North, SST 
                         anomalies with same signal over equatorial and subtropical region 
                         and different signal over intermediate region. The first and third 
                         patterns show greater interannual variability and the second 
                         pattern interdecadal variability. The first and second pattern 
                         does not show correlation significant with summertime convection 
                         over South America. The third pattern shows correlation 
                         significant with summertime convection only over northern of South 
                         America. The convection in this region is associated with positive 
                         SST anomalies over equatorial and subtropical region and negative 
                         SST over tropical region. The first coupled mode between SST 
                         anomalies over North Atlantic and OLR anomalies over South America 
                         determined by SVD corresponds to the third mode of the SST 
                         anomalies over North Atlantic determined by PCA. Thus, apparently, 
                         third mode of the SST anomalies over North Atlantic ((Equator - 
                         40ºN and 70ºW - 0º) has greater influence over summertime 
                         convection over South America than the two first modes. Results 
                         indicate also that North Atlantic (Equator - 40ºN and 70ºW - 0º) 
                         SST has influence only in the summertime convection over northern 
                         South America.",
