A NUMERICAL SIMULATION OF WIND-DRIVEN BAROCLINIC OCEAN CIRCULATION

A three-level baroclinic ocean model has been developed for studying climate and climatic change.The major large-scale features of temperature field,such as the belt of cold water,strong upwelling and the main currents in the Pacific Ocean,have been reproduced.The simulated results show that the seasonal variation of current is related to that of trade wind system.The simulated equatorial countercurrent is strong in summer and weak even vanished in winter.The south equatorial current,north of the equator is stronger in winter than in summer,but the contrary is the case with the current existing in the Southern Hemisphere.
