Abstract
A remarkable thermohaline front was observed at the mouth of Tokyo Bay, Japan, in winter. Water temperature changed from 14.5°C to 17.0°C and salinity from 34.0 ppt. to 34.8 ppt. across the front, but little density difference was observed. The generation mechanism of such a thermohaline front is investigated by use of a threedimensional numerical experiment. The thermohaline front is formed at the leading edge of the density-driven current due to the salinity efflux from the inner boundary of the Bay. The dependence of sharpness and position of the thermohaline front on the external parameters such as surface cooling rate, river discharge, and boundary conditions of water temperature and salinity is also examined numerically.
