- Аннотация: In-situ knowledge on characteristics of mineral aerosols is important for weather andclimate prediction models, particularly for modeling such processes as the entrainment, transport anddeposition of aerosols. However, field measurements of the dust emission flux, dust size distributionand its chemical composition under realistic wind conditions remain rare. In this study, we presentexperimental data over annual expeditions in the arid and semi-arid zones of the Caspian LowlandDesert (Kalmykia, south of Russia); we evaluate characteristics of mineral aerosol concentration andfluxes, estimate its chemical composition and calculate its long-distance transport characteristics. Themass concentration in different years ranges from several tens to several hundred of g m3. Thesignificant influence of wind velocity on the value of mass and counting concentration and on theproposed entrainment mechanisms is confirmed. An increased content of anthropogenic elements(S, Sn, Pb, Bi, Mo, Ag, Cd, Hg, etc.), which is characteristic for all observation points in the south ofthe European Russia, is found. The trajectory analysis show that long-range air particles transportfrom the Caspian Lowland Desert to the central regions of European Russia tends to increase in therecent decades.
