Climatic Teleconnections in the Western South Pacific with El-Niño Phenomenon

Abstract

In the western South Pacific, one year after a typical El Niño event, anomalous hydroclimatic conditions replace the usual ones. The abnormal meteorological conditions are characterized by the Inter-tropical Convergence Zone of the winds being arrested close to the equator. The equatorial area becomes rainy, and south of 10°S the wet season does not occur. The statistical comparison of the rainfall data with the intensity of El Niño events of the previous year shows a consistent correlation between both phenomena.
