Atmospheric pollution is associated with weather conditions. Meteorological processes make a significant contribution to the creation of unfavorable meteorological conditions (NMU). NMUs are a special shortterm combination of meteorological factors contributing to the accumulation of pollutants in the surface layer of atmospheric air. We draw a particular attention to the temperature stratification of the lower layers of the atmosphere which can cause a temperature inversion – an increase in air temperature with altitude. Temperature inversion limits the vertical dispersion of harmful impurities in the atmosphere. Observational data show that the increased level of air pollution in the city of Krasnoyarsk is most pronounced in winter with temperature inversion and weak winds (no more than 1-2 m/s). To predict periods of increased concentration of pollutants in the boundary layer of the Krasnoyarsk atmosphere we consider a numerical algorithm for determining the time intervals of formation and destruction of temperature inversion based on a onedimensional vertical model.
