中文摘要	利用塔克拉玛干沙漠腹地塔中大气环境观测试验站2013年3月至2014年2月地面常规气象观测资料和PM_(10)质量浓度数据,运用聚类分析方法对影响沙漠腹地沙尘浓度的地面天气系统进行了分型,分析了沙尘浓度与气象要素、地面天气系统的关系,并运用后向轨迹簇分析方法研究不同气团移动路径下沙尘浓度的变化。聚类分析结果表明:影响沙漠腹地沙尘浓度的主要地面天气系统分为4类,对应其天气环流形势分别为冷空气入侵、反气旋控制、锋前热低压和中小尺度型。轨迹簇分析与地面天气系统分类结果相一致,表现出明显的季节性特征。研究结果可为该区域沙尘天气的地面天气分型与大气环境质量预报提供科学参考。
英文摘要	Based on the data of mass concentration of PM_(10) and the routine weather observation at Tazhong meteorological station in the hinterland of the Taklimakan Desert from March of 2013 to February of 2014,Clustering analysis was used to classify the synoptic patterns which affect the dust concentration,and the relationships between heavy dust concentration and meteorological factors,as well as the surface synoptic patterns. The results of clustering analysis indicated that the surface synoptic patterns favorable for dust concentration could be classified to four patterns,which were under the control of anticyclone,the intrusion of cold air,thermal low ahead of cold front and mesoscale and microscale synoptic system. The result of back trajectory cluster analysis was consistent with the result obtained by clustering analysis,which had obviously seasonal characteristics. The research results provided scientific reference for air quality forecast and the weather classification.
