Abstract

The article provides an overview of the problem of changing the thermal regime of the lakes of the temperate zone of the northern hemisphere. Interrelations between meteorological conditions on the territory of Belarus and thermodynamic processes in different types of lakes are revealed. The issues of the influ-ence of air temperature and wind speed on the heat storage of the water mass and the thermal structure of water bodies in Belarus are considered. An analysis of the long-term dynamics of heat storage and thermal stability is gi-ven. The tendency to an increase in thermal stability and heat storage of the studied water bodies, which has been particularly pronounced in the last two decades, is shown. In deep lakes, this contributed to the enhancement of ther-mal stratification and the deterioration of the gas regime in the bottom layers during the summer period. A more si-gnificant increase in thermal stability may result in the transition of mid-deep lakes from a polymictic state to a di-mictic one, and, as a result, a decrease in the oxygen concentration in hypolimnion.
