Abstract

On the basis of shallow water equations, a 2-dimensional model for the wind-driven current is developed in this paper to simulate the mean wind-driven circulation and sea-surface elevation fields respectively in winter and summer, and to describe the general nature of the wind-driven current in the Bohai Sea.
Numerical results show that the patterns of the wind-driven circulation in Bohai are mainly the cyclonic circulation in winter and both cyclonic and anticyclonic circulations in summer. A theoretical argument based on vorticity is put up to explain the generating-mechanism of large eddies near the strait, which are considered to be the direct results of the wind stress interaction with topography gradients.
