本文研究了东海黑潮回流区的表层流。利用高频雷达观测的冲绳西部表层流场和日本近海可预报性试验（JCOPE）同化结果进行了分析。JCOPE资料显示，黑潮最东端的海流向南分叉并流入冲绳以西。这些水流被称为黑潮向南再循环流。海流受海底地形控制。在JCOPE观测资料中出现分叉流的区域风应力旋度为负值，而黑潮东部的风应力旋度为正值。黑潮南向环流有时会增强，其增强与正、负风应力旋度的增强相一致。
The surface current of the Kuroshio recirculation region in the East China Sea is investigated. The surface currents in the west of Okinawa Island observed by HF radars and the assimilation results of the Japan Coastal Ocean Predictability Experiment (JCOPE) are analyzed. It appeared that currents in the easternmost edge of the Kuroshio bifurcate southward and flow into the west of Okinawa Island from JCOPE data. The currents are called Kuroshio southward recirculation currents. The currents are controlled by the bottom topography. The wind stress curl in the area where the bifurcated current can be seen in JCOPE data is negative, while the curl is positive in the eastern portion of the Kuroshio. The Kuroshio southward recirculation currents are sometimes enhanced, and their enhancement coincides with that of the positive and negative wind stress curls.
