Research output: Contribution to journalArticlepeer-review


To determine the impact of the Indian Ocean sea surface temperature (SST) variability on the Pacific El Niño-Southern Oscillation (ENSO), two state-of-the-art coupled atmosphere-ocean general circulation model experiments were considered. It was found that ENSO variability is significantly reduced when air-sea interactions over the Indian Ocean are short-circuited. Furthermore, it was observed that warm ENSO events are stronger and occur more frequently when Indian Ocean SST in the previous summer is anomalously cold, whereas the warm ENSO events are weaker and occur less frequently when the Indian Ocean is anomalously warm.
