东海黑潮水团是东海海域的主要水团。夏季,东海黑潮水团一般划分为四层结构:黑潮表层水、黑潮次表层水、黑潮中层水和黑潮深层水。在冬季,由于大陆沿岸水系势力减弱,以及强烈的表层冷却产生的垂直对流作用,使黑潮表层水变性而和次表层水融为一体,从而使海面至400米层左右的黑潮水体呈现高盐特征。因此,冬季的东海黑潮水团变为三层结构,即黑潮上层水、黑潮中层水和黑潮
The Kuroshio in the East China Sea is the main water mass in the East China Sea. In summer, the Kuroshio water mass in the East China Sea is generally divided into four layers: Kuroshio surface water, Kuroshio sub-surface water, Kuroshio middle layer water and Kuroshio deep water. In winter, due to the weakened water system on the mainland coast and the intense vertical convection caused by surface cooling, the surface water of the Kuroshio degenerates into one with subsurface water, resulting in a high level of Kuroshio water around the sea surface of 400 meters Salt characteristics. Therefore, in winter, the Kuroshio in the East China Sea has become a three-layer structure, namely the Kuroshio upper layer water, the Kuroshio middle layer water and the Kuroshio
