Abstract

According to the characteristics of Sand-dust aerosol in northwest of China, the Sand-dust aerosol particle size distributions have been measured. A great deal of data have been collected in different weather conditions, which include background, floating dust, blowing sand, and sand storm. The rules have been found out through statistical analysis. Sand aerosol concentration is changeable in different weather conditions and process. During the blowing sand and sand storm weather, aerosol concentration changes a lot, but during the floating dust weather, it changes a little. The stronger the aerosol concentration is, the more the number of aerosol particles (d>2.5 m) is , and the more obvious changes occurs in the concentration of various diameter ranges. During different processes, coarse and fine particles have different contributions to the surface concentration. Through comparing the results, the wind speed is an important factor in weather conditions, and in different dust weathers, the PM1, PM2.5 and PM10 distribution different greatly.
