Abstract
Study of the Synoptic Characteristics of a Severe Dust Storm over Iraq Using Regional Climate Model 4

This paper focuses on the study of the characteristics of severe dust storms prevailing in Iraq
Regional Climate Model version 4 (RegCM4) is offered as a part of hands-on extended laboratory sessions during a series of workshops on Weather Physics and Climate Group organized at the International Center for Theoretical Physics (ICTP)
Summary
The term dust storm is used when the particulate particles suspended in the atmosphere extend at large distances and affect the cities. Atmospheric phenomena known as dust storms are caused by the transfer of mineral dust from the surface of the earth to the surrounding air, which is usually associated with dry and semi-arid regions, but can occur as a result of changes in the surface of the earth such as low vegetation and others [2]. The dust storm occurs when wind speed rapidly changes with height (i.e. shear stress formed). It means that the wind has reached a high speed. The characteristics and type of the earth's surface in terms of roughness and vegetation play a major role in determining the wind's ability to lift dust particles in addition to the speed of the surrounding wind [4].
