On the example of the Peter-the-Great Bay, located in the north-western part of the Sea of Japan, it is shown the change of hydrological conditions under the influence of monsoon winds. It is established that the Bay waters at the depths of more than 40 meters are completely replaced by the waters of the open part of the Sea of Japan.
It is given a physical model of the waters ventilation in the Sea of Japan, the main mechanism of which is the formation and growth of the vertical circulation cell during the autumn-winter season; its dynamics is predetermined by the wind influence, convection, and compensatory current on the background of the temperature decrease with the upwelling.
