Numerical Study of Gas and Aerosol Impurity Transfer and Transformation Processes in the Plume of the Norilsk Industrial Region

Models for estimating the average and maximum concentrations of chemically active impurities in cross sections of their plumes from remote stationary sources are proposed. The models were tested with the use of aircraft sounding data on the multicomponent contamination of the winter atmosphere in the Norilsk industrial region. The process of gas–particle active transition observed at a distance of 58–103 km from the emission source is numerically studied. The average and maximum sulfur oxidation rates in the winter polar atmosphere are estimated as 0.027–0.034 and 0.055–0.07 h−1, respectively.
