Application of Mathematical Modelling Methods in Mesoand Small-Scale Assessment of Atmospheric Air State

Abstract

The purpose is a meso- and small-scale characterisation of atmospheric pollution using mathematical modelling tools. Materials and methods. The method of mathematical modelling was applied to characterise the level of atmospheric air pollution for large areas. Concentrations of pollutants in the atmosphere were calculated for the territories of the Volga and Urals Federal Districts, the Republics of Udmurtia and Bashkortostan. To take into account the infl uence of orographic factor it was proposed to introduce a correction coeffi cient. Results and discussion. The areas of increased pollution were identifi ed. Application of the adapted technique (taking into account orographic factor) showed the necessity of its approbation for the territory with more fragmented relief (regions of Eastern Siberia). Conclusions. The results of statistical verifi cation showed the admissibility of using mathematical modelling methods in assessing the atmospheric air state of territories characterised by large size.
