Numerical simulation of dust occurrence in the atmosphere over homogeneous terrain

Resumen

A numerical model of dust storm occurrence during periods of strong prevailing flow over homogeneous terrain is presented. The model, which is time-dependent, includes a prediction of the Earth's surface temperature with the force-restore method. Turbulent mixing along the vertical is incorporated through a second order formulation of turbulent fluxes. The model is used to simulate the occurrence of dust storms over Kuwait in June 1973. The simulation is able to reproduce the observed diurnal variation of dust storms. The model is also used to analyze the dependence of dust storms on the prevailing wind speed as well as on dust particle size. The results of the analysis are described.
