Abstract :
Background and Purpose: Recently, aerosols as one of the air pollutants (with natural or anthropogenic sources) have received increasing attention. In this study, the purpose is investigation of soil potential in production of dust (aerosol) storms using wind rose and storm rose. Material and Methodology: Meteorological data and WRPLOT view software were used to draw the wind rose and hurricanes. Also, in order to study the wind direction on dusty days, the data of the Meteorological Organization and also to investigate the effect of meteorological parameters such as gentle wind percentage and prevailing wind percentage, statistical methods such as regression relationship, Pearson coefficient have been used. Also, the trend of annual and seasonal changes in the concentration of suspended particles (dust) has been studied in order to determine the seasons with the highest frequency of dust occurrence. Results: The results indicated that winds blow from northwestern and west in all seasons. The highest frequency of winds is western. The wind roses of spring and summer indicated that the most frequent direction of prevailing winds are western to northwestern. Southeastern direction comes in next level. These storms are more frequent in winter and autumn seasons. Also, investigation of storm roses demonstrated that dominant winds have speed of less than 4.5 meter per second (80%). This research shows that in study area, winds cannot erode the soil and product the aerosols. Discussion and Conclusion: Therefore, the main source of recent dust must be searched in the neighboring countries.
