    During summer in Tokyo Bay, the upwelling of the anoxic water strongly affects eggs and larvae of fish and shellfish. The northerly wind causes the upwelling along the eastern coast and near the bay head and downwelling along the western coast. Numerical experiments were carried with a three-dimensional model to explain the wind-induced circulation in Tokyo Bay. When a uniform north-easterly wind is imposed at the sea surface, the circulation almost reaches steady state, due to geostrophic adjustment, after one inertial period from the beginning of the computation. A forced internal Kelvin wave, propagating with the land on the right, is found to have a great effect on the development of the steady state. When the observed variable wind is given as the surface boundary condition, the results of the numerical experiment agree qualitatively with data from both the sea-surface temperature obtained by satellite images and field measurements at moored stations in the bay.
