Abstract

In light of the extremely high spatiotemporal variability of meteorological conditions, we propose a method for precipitation observation, which allows us to determine its composition depending on the factors of air mass formation, in order to monitor the processes of distribution and deposition of anthropogenic impurities in the Central Ecological Zone of Lake Baikal. By combining trajectory and chemical analyses, we identified the main factors influencing the formation of the chemical composition of precipitation. All events were divided into groups by the similar conditions of air mass formation and by the chemical composition. The main factors are local background, area of air mass formation, synoptic parameters, and intensity of wildfires.
