                         basin-wide (IOBW) mode and El NiñoSouthern Oscillation (ENSO) in 
                         the atmospheric circulation and rainfall interannual variations 
                         over South America (SA) during southern summer of the 
                         1951\‒2016 period. The effects of the warm IOBW and El Niño 
                         (EN) events, and of the cold IOBW and La Niña (LN) events are 
                         examined using partial correlations. The ENSO and IOBW modes, 
                         through the associated large-scale and regional anomalous 
                         circulation patterns, induce contrasting effects on the rainfall 
                         in northeastern SA. The EN without the warm IOBW effect induces 
                         anomalously dry conditions over eastern Amazon and part of 
                         northeastern Brazil (NEB) through anomalous sinking motions of the 
                         EN-related anomalous Walker and Hadley cells and strong moisture 
                         divergence associated with a vigorous anticyclone over tropical 
                         South Atlantic (TSA) and SA. The warm IOBW without the EN effect 
                         induces anomalously wet conditions in NEB, which is marginally 
                         related to the anomalous Walker and Hadley cells but is modulated 
                         by an anticyclone over SA between the equator and 20° S, and a 
                         cyclone in the southwestern Atlantic between 20° S and 40° S. The 
                         results here might be relevant for climate monitoring and modeling 
                         studies.",
