While gravitational processes on slopes occur during warm period, deflation takes place in winter. It makes possible to correlate eolian deposits with deflated material by granulometric composition. Coarse dust, to lesser extent thin dust, and clay particles appear due to frost weathering of sandy grains on the slope and their fragmentation in the windblast. The amount of eolian particles depends on intensity of wind.
