摘　　要：基于1979—2008年的表面漂流浮标资料,在选定区域(21°～33°N,120°～132°E)内对3个东海黑潮特征断面上的表层流速结构进行分析。选取的特征断面分别是位于台湾东北东海黑潮南段的SS断面,位于黑潮所流经东海的中央地段的PN断面和位于日本九州与奄美群岛之间的TT断面。Argos漂流浮标资料的统计结果能够较好地反映东海黑潮不同流段的主要特征及其季节变化。东海黑潮中段相对于其他流段流速强、流幅宽、流量大的特征最为显著,也最为稳定。The Argos drifter data obtained from the selected area（21°～33°N,120°～132°E）in 1979—2008 are analyzed to learn the characteristics of Kuroshio across the three sections in the East China Sea.The three sections are the SS section locating in the sea area northeast of Taiwan and representing the south segment of Kuroshio in the East China Sea（ECSK for the abbreviation）,the PN section representing the middle segment of ESCK,and the TT section locating in the sea area between Kyushu and the Amami Islands.It is learnt from the statistical results that the main features and the seasonal variations of the EC-SK segments respectively across the setions can be better reflected in the Argos drifter data.Especially atthe middle segment of ECSK,the current speed is stronger,the current width is wider,and the current flowing-volume is greater.All those features at the middle segment of ECSK becomes the most significant and the most stable.
