本文简述了近几年来在东海北部的气旋型涡旋区所进行的调查结果。根据调查所得之温度场、质量场及实测流场的分布趋势指出:每次调查期间济州岛西南海区的气旋型涡旋运动是存在的。文中还将这几年调查所得之余流矢量连同历史上同期所得余流矢量绘在一起,结果可完整地显示出一个气旋型流场来。文中还讨论了东海北部的黄海沿岸流的基本特征。本文的结果进一步证实了关于该气旋型涡旋常年存在、位置基本稳定的论断是正确的。
This article describes the results of a survey conducted in the cyclonic vortex in the northern East China Sea in recent years. According to the distribution of the temperature field, the mass field and the measured flow field obtained from the survey, it is pointed out that the cyclonic vortex movement exists in the southwest sea area of Jeju Island during each survey. In this paper, we will also draw together the residual flow vectors obtained from these surveys in recent years with the residual flow vectors obtained in the same period in history. As a result, a cyclonic flow field can be completely displayed. The article also discusses the basic characteristics of the Yellow Sea coast flow in the northern part of the East China Sea. The result of this paper further confirms that the conclusion that the cyclone-type vortex is perennial and its position is basically stable is correct.
