摘　　要：利用WOCE-SVP和中国近海环流观察项目的卫星跟踪表层测流浮标资料,详细分析了黑潮及其入侵东海陆架和东海陆架上层环流的分布状况。结果表明:黑潮从台湾东部进入东海后,明显入侵陆架,并在复杂地形的作用下使其流路呈现多种变化。分析结果还显示,对马暖流不仅仅是黑潮的延续,而是多支流合成的结果。通过资料分析发现:秋季东海黑潮西侧100m等深线处可能存在一支与黑潮反向的逆流,关于它存在的季节变化和动力机制有待进一步的深入研究。A vast amount of satellite tracked drifter data were used to analyse the distributions of the Kuroshio in the East China Sea and the upper layer circulation in the shelf area. It is shown from the analysis results that the Kuroshio intruds obviously into the shelf area after flowing in the East China Sea from the area east of Taiwan and has variable flowing path under the influence of complex topography; and the Tsushima Warm Current is not only the extension of Kuroshio, but also the confluence of several currents. It is shown from the data analysis that there might be a countercurrent flowing counter to the Kuroshio direction at 100 m isobath west of the Kuroshio in the East China Sea in autumn, and the seasonal variations and dynamic mechanism of the countercurrent remain to be further studied.
