Based on the two layer box model for Bays of Tokyo and Mikawa the transport of gravitational circulation was estimated and compared with the river discharge in winter and summer. The transport of the circulation exceeds the river discharge remarkably, but the ratio of the former to the latter is smaller in summer than in winter. It suggests that the gravitational circulation is likely to be suppressed in summer, because of its strong density stratification. The amount itself of the transport, however, is larger in summer than in winter in Tokyo Bay, and comparable in the both seasons in Mikawa Bay. It is attributed to the abundance of the river discharge in summer. Moreover, the residence time of river water is shorter in summer than in winter in the respective bays. Therefore, we can conclude that the sea water in the lower layer of bay is not so stagnant as believed intuitively but circulates actively even in the warm season.
