Changes in the equatorial Pacific will be visible first due to a stronger increase in EP-ENSO rainfall response, leading to increased SST variability.
ENSO’s scale is significant enough to influence global climate. According to the study, published in Nature Communications journal, increased SST variability from ENSO in the eastern Equatorial Pacific (EP) will emerge around 2030 ( error margin of +/- 6 years), more than a decade earlier than that of the central Pacific ENSO. If CP and EP are not separated, SST variability from ENSO will occur almost four decades earlier than previously suggested. Changes in the equatorial Pacific will be visible first due to a stronger increase in EP-ENSO rainfall response, leading to increased SST variability.
