Surface Concentration Values Simulation Using WRF Models and GOCART Scheme in Southeast Iran (Case Study: December 16-20, 2016 Storm)

Blowing dust is one of the most common natural phenomena in arid and semi-arid regions, which causes a lot of damage every time it occurs. This phenomenon is introduced as a natural hazard in terms of negative effects in natural and human-managed ecosystems, and it is one of the most important problems of societies in arid and semi-arid regions. This research was simulated using the WRF-Chem model and GOCART scheme in the Jazmurian basin in southeast Iran to investigate and analyze this phenomenon. The results showed that the numerical simulation of the dust storm using the WRF-Chem model simulated surface dust concentration values UTC18 on December 17, 2016, in the south of Sistan and Baluchistan province and Hormozgan province were higher than 2500 µg/m3, and more than 2000 µg/m3 in the central areas of Jazmurian region. To prevent destructive dust storms and reduce the emission of dust in this region, international protocols are needed for the correction and rehabilitation of degraded lands and activities to prevent desertification to stabilize degraded soils.
