英文摘要 | Summer-mean Indian rainfall (June to September) decreases during a developing El Nino. Here we investigate the variability and predictability of Indian rainfall in each summer month with a focus on June, the onset month of the Indian summer monsoon (ISM). We find that Indian rainfall in June is affected by both concurrent and antecedent El Nino conditions, with a larger contribution from the latter. During the post-El Nino June, rainfall decreases over central and northeastern India with anomalously extended premonsoon heatwaves as the positive sea surface temperature (SST) anomalies over the north Indian Ocean delay the onset of the ISM. Our results suggest that the prediction of Indian rainfall in June needs to consider concurrent SST anomalies over both the equatorial Pacific and north Indian Oceans. A better prediction of El Nino-Southern Oscillation and north Indian Ocean SSTs can improve the prediction of the ISM onset, the termination of premonsoon heatwaves, and Indian rainfall in June. |
