Based on numerical modeling methods (a generalized three dimensional barotropic linear model of Felsenbaum was used for the case of taking into account Rayleigh friction), the paper considers features of the structure of the current vectors field depending on wind conditions in an upwelling situation in the water area located along the northern coast of the Sevastopol seaside, between Capes Lukull and Tolsty. A twolayer transverse cell of water circulation, typical of upwelling, was identified. The currents were predominantly oriented down wind in the upper layer and in the opposite direction in the bottom layer. It is shown that in the analyzed water area upwelling was caused by northerly, northeasterly, easterly and southeasterly winds. Upwellings caused by the above winds differed in their location and area. Under a northeasterly wind, upwelling was most intense and widespread throughout the water area under consideration. Under a southeasterly wind, upwelling was formed in two small areas: in the bends of the coast, between Capes Margopulo and Lukull and north of Cape Tolsty. The modeling result was compared with data from expeditionary research. Their good agreement under a northerly wind was found.
