Numerical modeling of the dynamics of the spring thermal bar in Lake Dolgoe (Belarus): preliminary results

Abstract

The results of numerical modeling of the dynamics of the spring thermal bar into Lake Dolgoe (Belarus), obtained using meteorological data from the Sharkovshchina station for April 2023, are presented. The dependence of the horizontal movement of the thermal bar front on the wind direction is revealed: the northern wind accelerates it, and the eastern wind slows it down. Modeled temperature distributions showed warming of water not only in the area where the channel flows from Lake Svyadovo, but also in the middle shallow part of the body of water.
