El Niño–Southern Oscillation (ENSO) exerts a strong positive influence on the precipitation variability over Central Southwest Asian (CSWA) region during the wet season that spans from November to April. We note that the ENSO influence varies intra-seasonally and has two components, one directly through the equatorial Pacific region and one indirectly through the tropical Indian Ocean. In both cases, ENSO exerts its influence through Rossby wave-like atmospheric anomalies. When the two components are in phase, ENSO has the strongest influence while it is weakest when they are out of phase. These findings suggest that improvements in sub-seasonal to seasonal scale predictability requires the better representation of intra-seasonal variability of ENSO teleconnection, as well as the role of inter-basin interactions in its propagation.
