ABSTRACT
A three-dimensional primitive equation coastal ocean circulation model with free surface and blocking topography coordinates has been developed and applied in the Yellow Sea and the East China Sea with high horizontal resolution of 5’ x 5’ lon x lat and 20 vertical layer. With the consideration of the real coasts, bottom topography, density gradient forcing and winds stress, and the reasonable treatment of the water exchange at the open boundaries, i.e. Taiwan Strait, Yonaguni Strait, Tsushima Strait and Yangtze River Mouth, the circulation and its seasonal variation in the Yellow Sea and the East China Sea are numerically investigated. Some basic features and the seasonal variation of the circulation in the Yellow Sea and the East China Sea have been obtained which are well consistent with the previous observed evidences and studies. The Kuroshio, the Taiwan Warm Current, the Tsushima Warm Current are relatively stable over the whole year, wind-induced current can weaken them in winter, and enhance them in summer. The Yellow Sea and the East China Sea flows northward into the middle Yellow Sea, and two coastal currents flows along the shoreline at two sides of the sea in winter, while in summer, the Yellow Sea Cold Water Mass circulation dominates. The seasonal circulation patterns are mainly determined and forced by monsoon wind, the open boundary forcing (especially, the Kuroshio) also plays an important role on the formation of the current system.
