Analysis shows intensified SST variability correlates with January–April rainfall changes in Southern India and Sri Lanka.

This research aims to investigate the relationship between ENSO and rainfall in Southern India and Sri Lanka.
Analyzed multiple precipitation datasets and atmospheric reanalysis products from 1950 to 2024.
Examined the correlation between JFMA-mean SISL rainfall and the Niño 3.4 index.
Conducted composite analyses of ENSO events and their rainfall impacts.
Found a strengthening negative correlation between SISL rainfall and the Niño 3.4 index since the late 1970s.
Identified the Northwest Pacific Anticyclone as a key factor linking Pacific SST variability to regional rainfall.
Noted stronger rainfall anomalies from Eastern Pacific ENSO events compared to Central Pacific events, though not statistically significant.

Lin et al. (2026) studied this question.
