Dust Production by Wind Erosion: Necessary Conditions and Estimates of Vertical Fluxes of Dust and Visibility Reduction by Dust

  • Chapter
Physics of desertification

Abstract

Differing meteorological conditions that supply sufficient momentum to the surface to sustain wind erosion are organized with respect to the ratio of boundary layer height to Monin-Obukof length, L. Conditions for large-scale dust storms include strong surface heating and a strong upper level momentum source.

Visibility is related to mass concentration by an equation MV = C, where visibility, C, is a constant and M is the mass concentration of dust in the air. Different studies of visibility versus dust concentration are related to distance from the source region.
