             abstract = "This paper examines the effects of the tropical Pacific Ocean 
                         (TPO) and Indian Ocean Dipole (IOD) modes in the interannual 
                         variations of austral spring rainfall over South America (SA). The 
                         TPO mode refers to the El Niņo-Southern Oscillation (ENSO). The 
                         isolated effects between IOD and TPO were estimated, events were 
                         chosen from the residual TPO (R-TPO) or residual IOD (R-IOD), and 
                         the IOD (TPO) effects for the R-TPO (R-IOD) composites were 
                         removed from the variables. One relevant result was the nonlinear 
                         precipitation response to R-TPO and R-IOD. This feature was 
                         accentuated for the R-IOD composites. The positive R-IOD composite 
                         showed significant negative precipitation anomalies along 
                         equatorial SA east of 55\◦ W and in subtropical western SA, 
                         and showed positive anomalies in northwestern SA and central 
                         Brazil. The negative R-IOD composite indicated significant 
                         positive precipitation anomalies in northwestern Amazon, 
                         centraleastern Brazil north of 20\◦ S, and western 
                         subtropical SA, and negative anomalies were found in western SA 
                         south of 30\◦ S. This nonlinearity was likely due to the 
                         distinct atmospheric circulation responses to the anomalous 
                         heating sources located in longitudinally distinct regions: the 
                         western tropical Indian Ocean and areas neighboring Indonesia. The 
                         results obtained in this study might be relevant for climate
