551.465The problem of the numerical analysis of currents in the Kerch Strait is studied within the framework of a linear nonstationary two-dimensional model in the nondivergent approximation. We describe the actual situation when the motion is induced by a breeze against the background of the daily average northeast wind. The breeze is specified as acting in a narrow coastal strip and can be classified as a zonal wind. The variations of circulation near the Tuzla Island are studied in detail. It is shown that the contribution of the breeze circulation to the total circulation can be significant for the explanation of the processes running in the Kerch Strait.

The regularities of the suspended matter distribution in the system of wind currents from the area of bottom elevation along the Omega Bay are revealed. Observational data show that in the region of bottom elevation there is a topographic quasi-stationary eddy cell accumulating pollutants. Based on numerical modeling, it is revealed that the meridional winds of all directions contribute to the transfer of the suspended matter from the area of elevation to the western coast of the bay to the beach area, to a small coastal area with a characteristic bend of the coastline. The most significant suspended matter flows are generated by northeasterly and southeasterly winds. With a westerly wind, the main flow of suspended matter is directed to the eastern coast of the bay. The weak easterly winds, typical for Sevastopol, do not cause the removal of suspended matter from the central area of the investigated bay.
