Abstract
The paper considers changes in the state of the environment in Krasnoyarsk and its environs during the existence of the smoke of large-scale Yakut fires in August 2021. The appearance of smoke aerosols in the atmosphere led to a weakening of the passage of solar radiation to the Earth's surface and, accordingly, to a decrease in the temperature of the active soil layer and the surface air layer. Advection of cooled air with high relative humidity over the surface of the Yenisei River in the lower reaches of the Krasnoyarsk HPP formed cooling mists.
