Propagation of Multicomponent Admixture in the Atmosphere in the Mountain-Steppe Zone

Article Preview

Abstract:

The article deals with the mathematical modeling of propagation in the near and far zones of impurities formed during man-made accidents. A three-dimensional numerical model for the propagation of impurities from a powerful source is developed. Meteorological parameters allow for more detailed investigation of air and soil pollution in the mesoscale region. The numerical analysis of the propagation of harmful impurities in the mountain-steppe zone is performed. Three-dimensional data on the concentration of pollutants in the air at different times is obtained. The washout of impurities by clouds and precipitation was taken into account. The characteristics of air pollution and the underlying surface at distances up to 200 km from the sources are determined. The calculations used meteorological parameters of the atmosphere, typical for warm and cold periods of the year in the main geographical areas of the Kabardino-Balkarian Republic from mountainous to steppe.
