Using automatic weather station and China and South Korea＇s cooperative sandstorm monitoring system in Zhurihe weather station in the middle region of Inner Mongolia, meteorological parameters and other data were observed in this region. The relationship between the micro meteorological parameters near earth and the intensity of dust-storm on March 9, 2006 were analyzed. At the same time, the characteristic of PM10 were also analyzed for the dust storm by utilizing China and South Korea＇s cooperative sandstorm monitoring system data. The results show that the Mongolian cyclone is the main reason to form the ultra strong storm ; the variations of the micro meteorological parameters of near earth during the ultra strong storm relate to position and intensity of the cyclone ; Temperature , pressure , humidity and the wind speed are closely related to intensity of the sandstorm; PM10 and intensity of sandstorm have good corresponding relation each other, and the highest PM10 value exceed 140 mg/m3 when the storm is in its most violent interval.
