Application of the trajectory approach using the model Hysplit in assessing the transport of air masses from possible sources of emission

The features of atmospheric circulation from the proposed source of atmospheric emission of the Shies station of the Arkhangelsk region were analyzed using the trajectories of air mass transfer according to calculations using HYSPLIT module. The dominant direction of air mass transfer from this point to the East is noted, so about 60 % of atmospheric impurities are naturally transferred to the territory of the Republic of Komi. The highest frequency of trajectories was noted for the territory of Ust Vym, Syktyvdin and South Western part of the Knyazhpogost regions. The repeatability of the transfer directions changes depending on the season
