摘要：

由黑潮派生的各种暖流对东海而言是重要的热能来源,它们的态势会极大地影响东海的温度分布,从而影响到生态系统的变化和发展。通过对2003年度东海暖流主干温度、暖舌前锋位置进行空间分析,并与历史状况比较,结果表明在2003年春夏黑潮和对马暖流的温度和势力与常年差不多,台湾暖流及黄海暖流比常年要弱一些;夏初各暖流都出现了较大幅度低于常年的状况,先是黑潮,然后台湾暖流、对马暖流最后是黄海暖流。而秋冬两季除黄海暖流只比常年略强一些外,各暖流均呈强势,不但温度较高,而且暖舌的伸展距离比常年有不同程度增加。特别是黑潮、台湾暖流和对马暖流在冬季都接近历史最强水平,而相对较弱的黄海暖流也比多年平均略强一些。

Deriving from Kuroshio,the warm currents are important sources of heat energy for the East China Sea,especially in winter.Their distribution and strengths will greatly influence the structure of sea temperature and affect further on the variation and development of the ecosystem.By analyzing temperatures and fronts of the warm currents in the East China Sea in 2003,and comparing them with the situations in different years,it is reviewed that in spring and summer in 2003,the temperatures and strengths of Kuroshio and Tsushima warm current are in their ordinary states while Taiwan warm current and Yellow Sea warm current experienced lower SST and weaker in strengths.Especially in the beginning of summer,there were big minus deviations of temperature exhibited in kuroshio,then Taiwan warm current,Tsushima current,and at last Yellow Sea warm current.In autumn and winter of this year,the strengths of Kuroshio,Taiwan warm current and Tsushima current were stronger,as the temperatures were higher and places that their warm tongues reached were farer than those in a regular year.Particularly in winter,the strengths of Kuroshio,Taiwan warm current and Tsushima current attained the highest in history,while the Yellow-sea warm current is only slightly stronger than the average.
