In the present study, using ERA5 data, the atmospheric conditions of severe soil storms from 16 to 18 August 98 (7 to 9 August 2019) were analyzed. It is then simulated using WRF-Chem model, using different emission schemes including AFWA, GOCART, SHAO1, SHAO2, SHAO3, severe east wind. Synoptic analysis showed that during the storm, with the establishment of high pressure near the Caspian Sea and Turkmenistan and seasonal thermal low pressure over the southeastern Iran, India and Pakistan as well as the penetration of cool air from the north and the formation of temperature and pressure gradients led to winds. The simulation results showed that the model well characterized the onset of dust from the south-east of the country in Sistan and Baluchestan province and then emitted it to large areas of east and south-east. AFWA and GOCART emission schemas are more consistent with observations (RGB images), while SHAO schemas have a significant error. The AFWA schema estimates dust concentration more than observations, but the trend of changes is consistent. The GOCART scheme is closer to the observations but has a significant error at the time of the dust peak.
