The results showed that Iraq was suffering to No. （18） dust storms in 2011. The highest wind speed recorded at the beginning of the composition of most the dust storms ranged of 6-10 m/s and the lowest wind speed values ranged of 10-14 m/s, while the direction of the wind in No. （14） dust storms were flowed from NW （northwest）, only No. （4） dust storms were flowed from southwest SW （southwest）, due to the fact that the prevailing wind in Iraq is NW in most days of the year. Atmospheric pressure values recorded for the day of dust storms are ranged of 960-990 millibar, due to the existence Iraq under high pressure system most days of the year.
