“…Such fact suggests that the northerly wind with over 4 days period is needed for developing the clockwise vortex in the Yellow Sea. Hsueh et al (1986) treated the current field which was induced by the eventlike northerly wind forcing with 2 days period, i.e. before the clockwise vortex propagated to the head of the Yellow Sea, northerly wind became weak.…”

“…In winter, a steady clockwise circulation was developed from surface to bottom in the Yellow Sea, while an anti-clockwise one in the northern part of the East China Sea from their results. On the other hand, a clockwise circulation was not so developed under the wind forced condition in the sequential pattern of the current vector of Hsueh et al (1986).…”

In the Yellow Sea, the north-westerly wind dominates in winter and the existence of horizontal clockwise circulation has been suggested (Yanagi and Takahashi, 1993). The formation and variation mechanisms of this clockwise circulation is investigated using the wind forced numerical model which has a simplified basin configuration of the Yellow Sea. The model results show that two vortices (an anticlockwise vortex off Chinese coast and a clockwise vortex off Korean coast) are generated by the uniform north-westerly wind. Both vortices propagate along the shelf slope as the first mode shelf waves. An anti-clockwise vortex can not grow because it does not balance to the wind forcing. On the other hand, a clockwise vortex can grow and it reaches to the equilibrium condition at the northern part of the Yellow Sea, because this circulation can balance to the wind forcing. The time scale to become into the equilibrium condition is about 2 days. From this fact, it is ascertained that a clockwise circulation in the basin is generated periodically according to the variable wind forcing with 4 days period. The steady part of the current field exists with the fluctuating one which is induced by the periodical north-westerly wind.

“…The TWC separates from the warm and saline Kuroshio Current, has seasonal variation, and is the confluence of severa1 other currents (Lie and Cho, 1994;Yu et al, 2002). A portion of the TWC may flow through the YS as the Yellow Sea Warm Current (YSWC), which is an intermittent intrusion caused by weakening of the surface wind stress in winter (Hsueh and Romea, 1986;Hur et al, 1999). Most saline water entering the YS may be transported via advection by the YSWC (Hur et al, 1999).…”

The surface currents over the Yellow and East China Seas are mapped from the Geostationary Ocean Color Imager (GOCI). Based on a composite of six intrusion events in January–April, the strong northward surface current in the Yellow Sea is shown to be concentrated along the deep trough, accompanied by a broad northward surface current over the East China Sea. From the corresponding surface winds, the episodic northward surface flow bursts appear to be associated with abrupt changes from the strong northerly winds to weak southerly winds during cold front passages. A three‐dimensional model driven with observed surface winds is used to simulate the observed shelf‐wide response to northerly winds. There is an outstanding agreement between the simulated and observed surface currents. The surface intrusion in the Yellow Sea is shown to be driven primarily by a barotropic longitudinal surface slope, while the strong northward current in the East China Sea is associated with a coastal trapped wave. Moreover, the surface intrusion is associated with a large volume transport, suggesting that the transient intrusions could be important in the northward heat transport. The unprecedented capability of GOCI satellite in providing a regional circulation pattern, in conjunction with complementary model simulations, could contribute greatly to understanding of the dynamics of the Yellow and East China Seas.
