东海冷涡位于济州岛西南约150公里处。在黄海暖流、黄海沿岸流和北上黑潮余流的共同作用下，该海区经历了一个复杂的流场系统。为了确定CEECS的强度，开发了一个简单的地下强度指数。由于中东欧国家可以通过最低温度来追踪，因此强度指数是由该区域内和周围各核心的平均海水温度差确定的。基于SODA方法，可以计算出CEECS次表层强度指数时间序列，并利用该时间序列分析了CEECS的年际变化。
The Cold Eddy in the East China Sea (CEECS) is located about 150 km southwest of Cheju Island. This region experiences a complex current system under the influences of the Yellow Sea Warm Current (YSWC), the Yellow Sea Coastal Current (YSCC), and the northward Kuroshio residual. To identify the strength of the CEECS, a simple subsurface intensity index is developed. Because the CEECS can be traced by temperature minimum, the intensity index is determined by the difference in sea temperature averaged across cores within and surrounding the region. Based on SODA, the CEECS subsurface intensity index time series can be calculated, with which the inter-annual variation of the CEECS is analyzed.
