Abstract

Four seasonal average sea surface wind field of China offshore was obtained through ERA-Interim data from ECMWF(European Centre for Medium-Range Weather Forecasts), so that the feature of seasonal wind field variation of China offshore was figured. The result shows that China offshore is a typical East Asian monsoon region where northerly monsoon is in vogue in winter and southerly monsoon is in vogue in summer. Then the feature of China offshore's sea surface wind field anomalies was analyzed with the method of empirical orthogonal function (EOF). The merging data of multiple satellites utilized in this study is from NCDC(National Climatic Data Center), which has been collected since Sept. 1987. Some results can be obtained by analyzing 313 monthly average data. The first mode of China offshore's sea surface wind field anomalies makes contribution to 63.94% of the total variance. This mode shows the seasonal variations of China offshore, which means that the type of feature is winter-summer monsoon oscillation. The second mode makes contribution to 12.35% of the total variance, which reflects the feature of sea surface wind field during the transition period of winter monsoon and summer monsoon, so it shows the type of spring-autumn oscillation. The third mode, contributed to 3.49% of the total variance, which shows fluctuation with an approximative period of half-year, reflects intraseasonal variation of sea surface wind field variation.
