| Abstract: | A model has been developed on the basis of the mesoscale dynamic model (MM5) coupling with a dust-transport model with a geographic information database to simulate the process of gas-particle transport, especially well-concerning the factor of the dust thermal drift and calculating on the parallel computers. Comparisons between observations of strong dust-storm eruption in March, 20 this year and model calculations indicate that the model is able to reproduce some key features of the dust transport. |
