Abstract

The paper presents the results of calculations of meteorological parameters and parameters that characterize air quality in the city, obtained with the use of mesoscale meteorology and impurity transport models. Changes in the numerically predicted wind velocity fields, temperature, and concentration of major air pollutants were considered in detail for the selected dates, when calm, cloudless, dry, and anticyclonic weather was observed in Tomsk. The numerical calculation results were compared with the experimental data obtained with the use of instruments of the Joint Use Center "Atmosphere" of V.E. Zuev Institute of Atmospheric Optics of the Siberian Branch of the RAS (hereinafter referred to as JUC "Atmosphere"). The studies, confirmed experimentally, have shown that the most unfavorable meteorological conditions at low (-30°- 20°C) ambient air temperatures, which lead to the accumulation of pollutants near the earth's surface, are weak wind of variable direction and stable or neutral stratification of the surface air.
