The results of a microscopic analysis of 39 samples of (snow) precipitation taken in the steppe zone of the south of Western Siberia during the cold period of 2019/20 are presented. The samples contain pollen grains of woody (Betula sp., Pinus sp.) and herbaceous taxa (Artemisia sp., families Asteraceae, Chenopodiaceae, Poaceae). The herbaceous samples predominate in the spectrum-51%. To determine the areas of pollen grain arrival, the frequency back trajectories of the air masses are calculated with the HYSPLIT model for the atmospheric boundary layer during 120 hours. Analysis of pressure topography maps, maps of distributions of snow cover, average velocities and wind directions has made it possible to identify the areas of arrival of the pollen grains. The area of arrival of Artemisia sp. is the territory of the Turan Plain.
