The use of Satellite Images to monitor the position of Dust Storm over Persian Gulf region

The frequency and intensity of dust storms may likely to change in southwest of Iran near to Persian Gulf region .Dust and sand storms occur when the sub-tropical jet stream pushing up from south of the Arabian peninsula and a polar front jet stream pushing down from the European continent .These events sometimes unrecognized by weather observers and satellite images provide a useful means for detect and monitor of dust storm. In recent years, several complex dust storms occurred (e.g. March 24 2003, April 17 2003, April 17 2007, May 17 2007) which caused huge damage in this region. In this study, the behavior of dust storm was investigated using satellite images. The meteorological observations and numerical models are also going to use to study the dynamics of this phenomenon in order to investigate evolution and mechanism of the meteorological system and its physical effects, such as visibility reduction, heavy winds, red sky, continuous heavy precipitation, and severe lightning.
