| Abstract: | 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. |
