Abstract

Abstract

To study how the air and sea interact with each other during El Niño/La Niña onsets,extended associate pattern analysis(EAPA)is adopted with the simple ocean data assimilation(SODA)data.The results show that as El Niño/La Niña's parents their behaviors are quite different,there does not exist a relatively independent tropical atmosphere but does exista relatively independent tropical Pacific because the air is heated from bottom surface instead of top surface and of much stronger baroclinic instability than the sea and has a very large inter-tropical convergence zone covering the most tropical Pacific.The idea that it is the wes er burst and wind convergence,coming from middle latitudes directly which produce the sea-water east ward movement and meridional convergence in the upper levels and result in the typical El Niño sea surface temperature warm signal is confirmed again.
