Modeling of atmospheric circulation and transport of impurities from natural and industrial sources in the Baikal region

Abstract

Summer scenarios simulating impurity transport in the Baikal region are considered. The tracers' distribution from the locations of forest wildfires in July-August 2019 is calculated with the ICM&MG SB RAS mesoscale model of atmospheric dynamics and admixture transport. The same meteorological scenarios are used to estimate the distribution of pollutants from emissions of boiler houses and thermal power plants in the region. The results demonstrate that smog from forest fires and industrial sources lead to the significant load on the atmosphere of the region.
