| 摘 要： | 基于1950～2000年太平洋月平均SST资料,运用Morlet小波分析等方法研究了西太平洋暖池表层暖水的纬向运移特征.结果表明:暖池表层暖水纬向运移的年际(2～8a)和年代际(10～16a)变化都非常明显;表层暖水的纬向运移于1982年前后经历了一次气候跃变,跃变后暖水东界的平均位置比跃变前东移了10个经度;表层暖水的纬向运移对ENSO暖(ElNiño)、冷(LaNiña)事件的形成和发展具有直接的作用.

| Abstract: | Based on the monthly mean SST data on 2 latitude multiplied by 2 longitude grid in the Pacific Ocean during 1950~2000,the zonal movement of surface warm water in the western Pacific warm pool in the equatorial Pacific band(5°N~5°S)was analyzed by using the Morlet wavelet transfor mation method.The results show that the maximum zonal movement range of surface warm water in the warm pool is 115 longitudes,and the eastern boundary of the surface warm water is of most striking interannual(2~8 a)and interdecadal(10~16 a)changes.The zonal movement of surface warm water in the warm pool underwent a climatic jump in about 1982,and as against cefore the jump,the eastern boundary of the surface warm water had migrated eastwards by 10 longitudes.Besides, the zonal movement of surface warm water in the warm pool plays a direct part in the formation and development of ENSO. |
