동해 연안에서 발생하는 중규모 와동류의 분포와 시간적인 변동에 관한 연구

Temperature data observed by NERDA and the satellite infrared imagery off the east coast of Korea from 1994 to 1998 for 5 years were analyzed to study the distribution, temporal change, and structure of mesoscale eddies appearing almost permanently off the east coast of Korea. Typically, the eddy distribution can be characterized by two cases; two-eddy case and three-eddy case. In 1995 and 1996, there were only two eddies, one northeast of Sokcho and the other around the Ulleung Island. In 1994, 1997 and 1998, three eddies were located off Wonsan, Sokcho and Youngduk. For two-eddy case, the Ulleung Eddy surrounded the Ulleung Island, whereas this eddy is located south of the island in three-eddy case.
