Abstract

In this paper, pollutant transport and atmospheric circulation in Pribaikalye for the period 2010-2018 are studied using the HYSPLIT model. To determine the repetition of unfavorable meteorological situations, causing the transport of emissions from big regional sources towards Lake Baikal, air mass forward trajectories were computed. To detect the transboundary transport, that points at the influence of remote pollution sources on the air over Baikal’s basin, air mass backward trajectories were analyzed. Interannual dynamics of air mass trajectory distribution by the regions of their formation and transboundary transport is investigated.
