Abstract

Automated instruments for measuring of (1) the dust aerosol particle concentrations and the dust aerosol particle size distribution function, (2) the vertical turbulent fluxes of the dust aerosol and (3) the electric characteristics of the windsand flux. The dust aerosol particle concentrations in the range from 0.5 to 5.0 mcm at heights 2 m and 20 cm were measured. The vertical turbulent fluxes and the uplift rate (reached 5 cm/s) of the dust aerosol were determined. Influence of the convective structures on the emission and turbulent fluxes of the dust aerosol was found. It was established that the average volume electric charge of the dust aerosol reached – 70 nC/m³ and the electric charge density at the surface did not exceed + 25 nC/m² .
