From May 27 to 28, 2008, North China experienced a continuous floating dust and heavy air pollution event. Shenyang appeared air pollution event under the influence of dust storm. The main causes and the weather situation of the event were analyzed. The results showed that strong cold air and Mongolia vortex aroused the dust storm. Mongolia ＂cortex developed while moving eastward and a cold front on the surface moved across the dry and loose areas in the east Mongolia and North China, thus resulted in the blowing dust or sand-dust storm. A large amount of fine dust particles moved to Shenyang with the upper-level westerly flow and then floating dusts formed over Shenyang.
