Change of Thermal Core for Kuroshio in the East China Sea

The thermal core of the Kuroshio in the East China Sea (ECS) sorted out by 5 % the high temperature region from surface to 500m depth using the data from World Ocean Atlas 2005. It is found, that the thermal core of the Kuroshio in ECS is close to west side on the surface, the thermal core moves toward east with depth increasing, it close to east side below 100m. At the northeast sea area of Taiwan island, the thermal core of the Kuroshio in ECS is close to continental shelf of ECS, there is a sharp bend for the thermal core, which turns from north to east. The point of elbow moves with season, it is close to the northmost side in summer and to the southmost in spring. There is another sharp bend for the thermal core at the southwest sea area of Kyushu, with turns from northeast to east. The point of elbow is close to the northeast in summer.
