Abstract: | We discuss the results of numerical experiments carried out within the framework of a new version of the quasiisopycnic model of the Black Sea [1, 2]. We take into account the stochasticity of the wind stress, vertical shift of the flow velocity in the upper quasihomogeneous layer, and diapycnic mixing. We generalize the procedure of “convective adjustment,” which enables us to consider the propagation and transformation of waters of the Sea of Marmara. It is shown that the consideration of these factors enables one to determine the structure and seasonal variability of hydrothermodynamic fields in the sea more correctly. Translated by Peter V.
