中文摘要	文章从空气动力学和天气学角度出发探讨了大风、对流层低层的强烈垂直不稳定及高、低空急流对哈尔滨沙尘天气做出的贡献,分析了沙尘天气时城市大气中几种主要污染物变化情况。研究表明,哈尔滨的沙尘天气主要来源是内蒙古中部的沙地,但近年也常出现本地沙源引起的沙尘天气;沙尘天气期间,城市大气中的可吸入颗粒物浓度出现异常,其浓度变化和沙尘天气具有同步性特征;沙尘天气期间,SO_2含量呈明显减弱趋势;NO_2污染物的浓度变化则表现较平稳。
英文摘要	From the angle of aerodynamic and synoptic meteorology, contributions of three factors, such as high wind, strong vertical instability of lower troposphere and upper/lower-level jet stream, to sandstorm weather in Harbin were analyzed. Change characteristics of atmospheric primary pollutants in sandstorm events were analyzed as well. Some conclusions were drewn as follows： first, the sand source of sandstorm weather in Harbin was desert in the midland of Neimenggu. But in recent years, sandstorm weather often occured just because of the local sand. Secondly, in sand storm day, the density of PM10 in the urban air, which is synchronous with the sand storm weather, obviously increased. At last, the density of SO_2 was sharply reduced when sandstorm weather occured. However, the density of NO_2 changes little.
