Abstract

Based on the sea surface temperature (SST) and sea level pressure (SLP) data, the temporal and spatial variations of sea surface temperature anomaly (SSTA) in Kuroshio have been analyzed in this paper by means of the method of Rotated Empirical Orthogonal Function (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 700 hPa are negative anomaly with enhancement of winter monsoon in the negative years and vice versa, and that there is a close relation between SSTA of this region and distribution pattern of wind anomaly at 850 hPa.
