Sand and dust storms (SDS) is a common weather phenomenon in the Middle East. Topography and the northern or northwesterly wind are the main control factors for types of SDS trajectories. The main SDS corridors in the Middle East were classified and spotted from March 2000 to March 2017. The SDS can be classified in the region in accordance to shape and magnitude into three main types namely; Small with 3 subtypes (Arrow shape-straight, Arrow shape-curved and Needle like), Intermediate with 3 subtypes (Curved, Hook and Straight), and Extensive with 6 subtypes (Spiral, Agglomerated-Dense, Agglomerated-Dispersed, Wavy, Hook-Single head, and Hook-multiple heads). Most of the trajectories are located within the northeastern parts of the Middle East. Dust properties led us to sort SDS and their indications. Dust deposits in the eastern Mediterranean Sea and the Red Sea and are initiated from Northern Desert of Africa (NDA). On the other hand, dust deposits in the Middle East originate from NDA, Western Desert of Iraq (WD), Mesopotamian Flood Plain (MFP), Ahwaz (HZ), Ahwar (HR) and Baluchistan Desert (BSH). The deposited dust in coastal areas is categorized as trimodal particle size distribution, finer mean size fractions with higher values of particles surface area and contains more carbonates and less quartz percentages compared to fallen dust in inland regions which is dominantly initiated from Western Desert of Iraq (WD), Nafud Desert (NFD) and Empty Quarter (EQ)..
