Annotation
The effect of wind on the development of a thermal bar and the accompanying currents in a reservoir during the melting of its ice cover are studied based on mathematical modeling. The thermohydrodynamic processes in a reservoir that is partially covered with ice in its central part are considered. The wind is shown to have a significant impact on the structure of currents. The behavior and lifetime of vortex structures in the reservoir, the location of the convergence zone, and the 4°C isotherm are determined by the velocity and direction of the wind. The interpretation of the thermal bar as an area of convergence of water masses near the isotherm of 4°C is shown to be incorrect, even at low wind velocities.
