摘要

Abstract

A POM based three-dimension baroclinic prognostic model in σ-coordinate was established to simulate the eddies in the East China Seas wintertime circulation

considering the topography

inflow and outflow on the open boundary

Changjiang runoff

heat

flux

and wind stress on the sea surface. The model results showed that three branches separate from the Kuroshio flow toward the interior of the Yellow Sea

and form three eddies respectively. The middle eddy is centered at 124°37′E

37°00′N

the southern eddy is centered at 124°00′E

35°30′N. The large cyclonic eddy centered at 125°06′E

30°30′N and located southwest of Cheju Island is a closed structure formed by the northeastward flowing Taiwan Warm Current

northwestward flowing Yellow Sea Warm Current and southward flowing coastal current. The Kuroshio intrusion engenders an eddy west of Kyushu Island of Japan. The branching of the Kuroshio is the direct dynamic cause of the formation of this large eddy. Moreover

both the topographic influence and the northward wind prevailing in winter affect the eddy's formation obviously.
