Based on the SST and SLP data,the temporal and spatial variations of SSTA in Kuroshio current region have been analyzed in this paper by means of the method of REOF.The results show that there is a spatial change feature as a whole in addition to a remarkable interannual/interdecadal change of SSTA.After dividing the positive and negative SSTA years and analyzing a lot of meteorological elements in corresponding years,it is obtained that the SLP in Kuroshio current region and the height field at 700hPa are negative anomaly with enhancement of winter monsoon in the negative year and vice versa,and that there is a close relation between SSTA of the region and distribution pattern of wind anomaly at 850hPa.
