Abstract

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.
