Characteristics of the Cold Water Body Northeast of Taiwan

Based on the historical marine observational data, the characteristics, structure and space-time distributions of the cold water body in the sea area northeast of Taiwan are analysed, and the main results are as follows. (1) The existence of the cold water body in winter was first verified by using the satellite tracked drifter trajectories. (2) In view of the importance of the cold water body, it is suggested to name the cold water body "Penghuamian" cold water body. (3) The cold water body results from the upwelling of subsurface Kuroshio water, which shows the influence of the Kuroshio on the Chinese marine environment. (4) The cold water body is characterized by low temperature, high salinity, high density, low dissolved oxygen, high phosphate, high silicate and high nitrate.
