| Abstract: |
| To study how the air and sea interact with each other during El Niño/La Ninña onsets,extended associate pattern analysis(EAPA) is adopted with the simple ocean data assimilation(SODA) data.The results show that as El Niño/La Ninña's parents their behaviors are quite different,there does not exist a relatively independent tropical atmosphere but does exist a relatively independent tropical Pacific Ocean because the air is heated from the bottom surface instead of the 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 Ocean.The idea that it is the wester burst and wind convergence,coming from middle latitudes directly that produce the seawater eastward movement and meridional convergence in the upper levels and result in the typical El Niño sea surface temperature warm signal is confirmed again. |
