Introduction: Every year natural hazards damage various parts of the planet. One of the hazards of the desert margin with a dry and semi-arid climate, including the Middle East, is dust. Dust reduces horizontal visibility and cancellation of flights, causes crashes, pulmonary and ocular diseases, work closures, air pollution, reduced water quality and damage to the agricultural sector, etc. Today, air pollution with dust is reported in different cities of Iran, including the storm in the July 18, 2009 in 18 provinces, with particles suspended from the desert of Syria and Iraq to Tehran and the amount of suspended particles with 460 ppm showed the highest record of polluting (Ranjbar Saadat Abadi & Azizi, 2012). Estimated economic losses in the western Iran (Ilam, Khuzestan and Kermanshah) from 2006-2011 were 2227 million dollars in the first scenario to $ 13361 million in the fourth scenario (Khalidi, 2013). Every year, 108 tons of dust particles are imported into the atmosphere, with the largest share of Africa (Kutiel & Furman, 2003). The Arabian Rub' al Khali Desert, the Tigris and Euphrates suburbs of the Euphrates and the coasts of Oman are the main focus of Middle East dust production (Prospero, Ginoux, Torres, Nicholson & Gill, ., 2002). In Iran, a significant dust storm trend was reported in the west (Rasouli, Sari Sarraf, & Mohammadi, 2011). Zabul with an average of 183 storms had the highest number, and Zahedan, Bushehr, Tabas, Bandar Abbas, Jask, Iranshahr, Hamadan and Ahvaz were the next, with the maximum number in July and minimum in December (Farajzadeh & Alizadeh, 2011). The two critical centers of dust in the southwest of Iran from 1979-2008, Dezful and Bushehr, have highest amount of dust in spring and lowest in December (Azizi, Miri, & Nabavi, 2012). The purpose of this study is to determine the pattern of spatial distribution, continuity, major sources and dust hour pattern in northeastern Iran...
