Based on the 1950-1998 sea surface temperature and 1958-1997 wind field reanalysis data of NCEP/NCAR,by using correlation,composite and singular value decompositionmethods,the relationship between SSTAs of Kuroshio and wind fields of the tropical Pacific has been studied in this article.The results show that:the key region wherein themeridional/zonal wind impacts the 3-month later SSTA of Kuroshio lies in the west tropical Pacific(140-160°E,5°S-5°N)/the central tropical Pacific(160°E-150°W,5°S-5°N),respectively,and the influence of wind fields in the two key regions on the Kuroshiomay persist for about six ormoremonths;and the intensity and range of zonal wind key region is far greater than themeridional wind one.Further study indicates that the SSTA of Kuroshio has a close relation with ENSO event:from the November of the current year of El Nino(La Nina)to the December of the next year,the SSTA of Kuroshio ismostly positive(negative).
