                         atmospheric circulation are examined, with emphasis on submonthly 
                         variations of the South Atlantic Convergence Zone (SACZ). Outgoing 
                         Longwae Radiation (OLR) is used as a proxy for convection, while 
                         associated circulation patterns are depicted by the NCEP 
                         reanalysis data. Correlations between submonthly (2-30 day) OLR in 
                         the vicinity of the SACZ and 200 mb streamfunction reveal the 
                         preferred path of Rossby wave energy impinging on the SACZ from 
                         the midlatitudes of the Southern Hemisphere. Episodes of enhanced 
                         convection withing the SACZ, indicated by negative OLR anomalies, 
                         occur at the leading edge of upper-level troughs propagating into 
                         the region. We speculate taht the relatively stable position of 
                         the SACZ may be associated with a Rossby wave guide, which is 
                         ultimately related to the large-scale circulation driven by 
                         sources and sinks of diabatic heating.",
