Abstract
Average annual wind speed in Iraq, about 2.9 m / sec, occurs highest rate of wind speed in half the warm of the year, especially in the months: May, June, and July, so recorded the highest frequency of dust storms and risingdust and suspended dust. While going less than the speed of the wind in the cold season of the year, especially in the months: November, December, and January, so recorded the lowest frequency of dust storms and rising dust and suspended dust. The station was Nasiriyah more country stations in the frequency of dust storms and dust rising, because it was the highest stations in the rate of speed of the wind. While the stations north of Kirkuk and Mosul from stations in the rate of less frequent dust storms and risingdust, because it was the less Iraq stations in average wind speed. As for the suspended dust was the highest stations repeatedly Baghdad station is the appropriate rate of winds Therefore, while it was less Rutba station terminals to the rocky nature of the soil. When extracting simple correlation coefficient application of the law Pearson appeared to be stronger relationship between the rate of wind speed and frequency of dust storms was in the station Nasiriyah about 0.971, while the strongest correlation with the risingdust in station Amara around 0.992, with the suspended dust in the station Basra, about 0.938
