Dr. Soo-Jin Sohn from APEC Climate Center (lead author), Prof. Chi-Yung Tam from The Chinese University of Hong Kong and Prof. Jong-Seong Kug from Pohang University of Science and Technology wrote the research paper entitled ‘How does The El Niño-Southern Oscillation (ENSO) diversity limit the skill of tropical Pacific precipitation forecasts in dynamical seasonal predictions?’. It was published in Climate Dynamics, one of well-known science journals.
Tropical rainfall in the equatorial Pacific region is significantly affected by El Niño, which is related to warm sea surface temperature. Therefore, understanding El Niño is very important in predicting tropical rainfall.
ENSO and its climate impacts, conventionally defined by the Nino3.4 index, do not reflect “ENSO diversity and its impacts on Climate”accordingly. Therefore, it was necessary to evaluate the predictive performance of the seasonal prediction model considering the ENSO diversity and its impact on climate. In addition, it was demonstrated that the ENSO diversity limits the predictive performance of the seasonal prediction model for precipitation in the tropical Pacific region.
