Abstract

The paper presents the results of the microscopic analysis of solid precipitation (snow) sampled from three key areas located in neighboring nival-glacial systems at the beginning of the cold period in 2019-2020 (November, December). Pollen of Pinus sp., Betula sp. belonging to Asteraceae, Chenopodiaceae, Poaceae families was found in the snow samples. The samples collected simultaneously from three key area on December 7, 2019 displayed 4 taxa out of 5 identified during the entire analyzed period as well as territories which pollen could be transferred from were identified. According to the backward air-mass trajectories calculation (HYSPLIT model), the analysis of constant pressure maps and snow distribution maps, these territories were located to the south of the key testing sites.
