| Abstract: | By the method of mathematical simulation, we study the evolution of local discharges of pollutants on the northwest shelf
of the Black Sea induced by the motion of a cyclone. We use the nonlinear equations of motion of a homogeneous viscous fluid
in the hydrostatic approximation and the equation of turbulent diffusion. A cyclonic formation is represented by a moving
axisymmetric area of low pressures. The discharges of pollutants are caused by the action of instantaneous sources located
on the sea surface. We perform the analysis of dependences of the paths of motion of polluted regions, the periods of their
dissipation, and the depths of penetration of pollutants on the bottom topography and the intensity of diffusion processes.
