Estimating the Characteristics of the Vertical Turbulent Viscosity in the Upper 200-m Layer of the Black Sea

摘要

The influence of high vertical velocity gradients in the Black Sea Rim Current on the intensity of the vertical turbulent exchange is demonstrated on the basis of numerical modeling based on CTD data. The vertical turbulent exchange is confirmed by the anomalous distribution of the hydrochemical parameters in the redox layer. A system of equations for the kinetic energy of the turbulence and dissipation rate (k-xi model) is used for the calculation of the coefficient of the vertical turbulent viscosity (diffusivity).
