        Fluid in a rotating coordinate generally flows along equi-potential vorticity line. Without disturbances such as dissipation, rapid vertical mixing, and external forcing such as energy exchanges, potential vorticity is conserved in the thermally and dynamically closed system. This study is the first trial to investigate the potential vorticity in the East Sea. The purpose of this study is to show the distribution of the potential vorticity due to the variation of sea water density and topography in baroclinic and barotropic conditions. The conclusions are given as follows. First, vertical mixing is well striking in February than in August, and flow patterns in February are different from those in August. Secondly, contour lines of isotrophe is similar to bottom topography, while potential vorticity is similar to the distribution of dynamic topography. Thirdly, the circulation of the East Sea Water flows approximately along contours of potential vorticity in the region of high baroclinicity and along those of isotrophe in other region.

        The circulation of the Yellow Sea and the East China Sea is simulated by means of the two layer numerical model with bottom topography: The circulation inside the Yellow Sea is mostly affected by the Kuroshio Current in the case without the wind stress exerting on the surface. The main current is trapped along the continental slope by the characteristics of geostrophy. The second strong current region is appeared from the southern coast of the Ghina to the Korea Straits, which is characterized the western boundary current. The circulation inside the Yellow Sea is rotated in clockwise direction even though its magnitude is negligibly small compare with the other current, for example, the tidal residual current.
