description abstract | The bimodality of the Kuroshio path south of Japan is presented from a new viewpoint of direct interaction of current with local coastal geometry. By solving the barotropic quasi-geostrophic equation in a channel with steplike coastal geometry, we demonstrate that the model Kuroshio can actually show the localized, bimodal behavior for a reasonable range of inlet current speed. The amplitude of the large meander is approximately given by 2Umax/?. In contrast to all ?nonlocal? model results, our local coherent structures have nothing to do with the basin-size geometry such as Kyushu and the Izu-Ogasawara Ridge. In general, the present study suggests that even a small feature of coastline geometry may trigger a big change in a nearshore current. | |
