Influence of Regional Atmospheric Processes on the Formation of Dust Pollution Layers in Belukha Glacial Deposits

Considered is a source of solid particles (dust) that are visually observed in the layers of an ice core sampled by a joint Russian–Swiss expedition in 2001 in a saddle of Mount Belukha of the Altai mountain massif (the Katun Range, Altai Republic). Based on analysis of the archival data and a synoptic situation in the Central Asian region, it was found that the most likely source of solid aerosol particles in a glacier layer dated by 1985 is the uplift and transport of the surface soil layer by a whirlwind, observed on August 7, 1985, in the settlement of Dolino, Rubtsov region, Altai Territory.
