  • 摘要:In recent years in particular, the detrimental impacts of dust storms around the world has become a matter of much concern. In this phenomenon, the movement of fine particles may fall into two categories of dry and wet depositions. It is a common practice to model dust deposition by a network of various resistances as it facilitates to characterize the impact of each mechanism on the overall rate of dry deposition. In this study, fewer assumptions are considered in comparison to previous models. The proposed model covers a wider range of conditions and also includes the impact of thermophoresis. Moreover, the complicated calculations of atmospheric stability and wind friction velocity are replaced with a simpler algorithm by using the meteorological data such as wind speed. The reliability of the modified deposition model is confirmed when compared with the available field data from the literature with good agreement both qualitatively and quantitatively.
