The Sultanate of Oman, which is located in the South East of the Arabian Peninsula is exposed to dust storms like many other countries in the Arab region. The Sultanate has been about seventy dust storms during the period from 2000 to 2014. Dust storms originate either in the North, North Eastern direction, or come from the West and North Western direction. Throught the last fifteen years, about eighteen dust storms formed from the North and North Eastern direction struck Oman. The Sultanate was also hit by approximately fifty two dust storms originating in the West and North Western part of country. The highest occurrence about 14 was in March and there was practically none in November. A myriad of technical studies have conducted to examine dust storms, follow their paths and identify their key sources and directions. Throught an analytical, experimental and evidential climatic data and satellite images, such studies have revealed that dust storms in the sultanate have occurred repeatedly between 2000 and 2014. In this respect, studies were also grounded on the Geographical Information Systems technique (GIS) in order to determine the standards of optical depth maps for blowing dust storm, its outer sources and distribution in different regions of Oman during the period from 2000 to 2014. Based on visual space (Meteosat-9) and (Meteosat-7) performed using Visual Analytics Process, studies have also verified that the Key outer sources of dust in the Sultanate are: The North and North Eastern namely the desert of Indian Thar, the desert of Afganistani Rajastan, Pakistani Balushistan and Iranian Sastan. And from the Western and North Western direction send the dust storms from the flood Plain that is dry, in the South of Iraq, and the dry flood Plain, and the desert of Al Sham in South of Syria and the desert of Al Nufoth and Al Dhana dunes in Saudi Arabian and desert Al Rub Al Khali. The analystic process of the Images Satellites (Multi - angle Spectroradiometer) (MISR Level 3) Which focuses on most of the standards of dusty blowing on the Western parts of Al Wasta governorate and on the North West of Dofar governorate. Whereas the Areas between the North Al Batina governorate and Al Burami governorate and Al Dahira governorate showed that there is reduction in all levels of dusty Blowing in most seasons of the year. It has also showed that July month is the most known of dust on the atmosphere of the Sultanate. And the fewest month is December.
