Abstract
Kinetics of dust propagation in Kakheti region is numerically studied. It is determined that in 100 m layer of atmosphere the process of turbulent diffusion take precedence in the process of dust propagation. From 100 m to 1 km the processes of diffusive and advective transfers are identical, while above 1 km the preference is given to advective transfer. Maximum values of dust concentration are obtained in 100 m surface air layer. Spatial dust distribution region increases and concentration decreases along with height increase. Urban influence zone is determined.
