Through the introduction of wind area index and zonal change index indicators,the 19602010 NCEP wind reanalysis data were used to describe the annual variation of wind field through Morlet wavelet analysis,so as to analyze the climate change of wind zone. The correlation between the wind field change index and ENSO Nino index was discussed by using sliding correlation analysis method. Results show that the wind zone in North Pacific high latitudes extends gradualy and has the trend to low latitude,and vice versa in low latitudes. The wind zone has different interannual and interdecadal period,and it has certain correlation with Nino index, and the correlation coefficient has abrupt change.
