英文摘要	One of the most important and relatively new natural disaster compared with others is the dust-storm phenomenon in today's world, which has been aggravated by rising drought and global warming. Studies on the phenomenon of dust have different aspects and characteristics. To study this phenomenon, the use of meteorological models such asHYSPLIT, as well as satellite images with high temporal resolution and storm detection in terms of intensity, etc., is necessary. In this research, modeling in HYSPLIT system with back trajectory analysis was performed at three levels of altitude to determine the direction of motion of suspended particles in the atmosphere and its source in the interval 48 h prior to the occurrence of twosimultaneousdust storm phenomena in destinations ofAhwazandKermanshahwith a new approach. The dust detection was done by analyzing MODIS images using the iTIIDI (Improved Thermal Infrared Integrated Dust Index) method along with bands different method to remove cloudy pixels by determination of an appropriate threshold in digital numbers. The comparison of the transmission trajectories of dust yielded by HYSPLIT model for two destinations and false color composite of detected dust in MODIS images demonstrated the same sources for the dust phenomenon at the time of the study. Subsequently, the hydrological parameters of the identified region as the source were also evaluated; all of these, reflected the region's ability to produce suspended particles. Generally, the primary sources of dust on the two cities of Ahvaz and Kermanshah were desert parts of the northern of Iraq, a region between latitudes 33.80 degrees N to 35.85 degrees N and longitudes 42.00 degrees E to 44.76 degrees E in Tigris and Euphrates alluvial plain.
