In this studyit is hypothesized that a low-level jet may play in role in generating the intensity of this source region. The presence of alow-level jet east of the Seistan mountains is documented here for the first time. The jet exists mainly from May toSeptember and has a core at 850 mb. Maximum speeds are at 18 UTC and 0 UTC and occur in July-August. In the meanthe core speed attains 20 ms-1 in those months. The jet attains a maximum at night, a minimum during the day. However, the vertical motions associated with it do not fluctuate greatly over the course of the day. The development of the jet during a dust outbreak in 2002 is also described. It arises a day or so before the outbreak and disappears as the outbreak ends.}, keywords = {Afghanistan,Iran,Low-level jet,Mineral Dust,MODIS}, url = {https://jdesert.ut.ac.ir/article_56473.html}, eprint = {https://jdesert.ut.ac.ir/article_56473_029d11199a321e18944cdfa92a6789eb.pdf} }
