The paper analyzes the meteorological conditions in Krasnoyarsk in the period from 2019 to 2020. The relationship between the occurrence of temperature inversions in the surface layer of the atmosphere and air pollution by suspended solid particles (PM2.5) is investigated. The paper uses a set of meteorological data of the NCEP GFS weather forecast model on air temperature on three isobaric surfaces (1000, 925 and 850 mb), wind gusts and the height of the atmospheric boundary layer. The air monitoring system of the KSC SB RAS provides data on solid particle concentrations PM2.5 and wind speed. The relationship between the presence of temperature inversions in the lower layer of the atmosphere and periods of significant air pollution is shown, as well as the dependence of changes in wind speed and the height of the boundary layer of the atmosphere with changes in the average daily PM2.5 concentration. The possibility of using the meteorological data of the NCEP GFS model to study the surface layer of the atmosphere and the periods of its pollution, predicting the deterioration of the environmental situation in Krasnoyarsk, is demonstrated.
