We present the results of numerical experiments aimed at the simulation of the circulation of waters and transport of impurities
in the Balaklava Bay for typical wind conditions established on the basis of the analysis of the data of in-situ measurements. The currents are computed by using the nonlinear σ-coordinate model. The specific features of the integral
circulation and three-dimensional structure of the current field are investigated. The statistical characteristics of currents
are estimated on the basis of the in-situ data on winds and model calculations. Possible scenarios of propagation of impurities from the coastal sources are analyzed
for various hydrodynamic conditions. It is shown that the localized eddy structures in the current fields (in combination
with the zones of intense vertical motion) can result in a complex character of the transport of substances in the bay and
lead to the formation of local regions of maximum concentrations of impurities on the boundary of the north and central parts
of the bay.

Experimental data provided by a hydrophysical profiling probe are invoked to examine the vertical and horizontal structures of the north equatorial countercurrent in the Atlantic Ocean. The kinematics of waters and the hydrological element distribution are compared. The countercurrent's major parameters have been identified and volume transport has been calculated.Translated by V.Puchkin. 相似文献

We discuss the results of a numerical experiment carried out within the framework of the most complete one-dimensional (integrated over the horizontal coordinates) version of the quasiisopycnic multilayer model taking into account the processes of diapycnic mass, heat, and salt exchange and the diffusion coefficients chosen according to the theory of double diffusion. The indicated experiment reproduces the vertical thermohaline structure of waters in the Sevastopol'skaya Bay and its variability in 1997–1999. For numerical computations, we use the actual data of meteorological observations and measurements of the discharge of the river Chernaya and the sea level. The comparison of the numerical results with the data of monthly hydrological surveys reveals their good agreement (not only qualitative but also quantitative). 相似文献
