利用塔克拉玛干沙漠大气环境观测试验站2010年4月11日沙尘天气风廓线雷达资料，分析了此次过程启动爆发的水平风场、垂直速度和雷达等效回波强度特征。研究表明：风廓线雷达是进行沙尘探测和监测的一种有效的高空大气遥感系统，它不仅可以捕捉到沙尘天气的开始和结束时间，而且能监测到沙尘在空中被输送的高度、厚度范围以及沙尘运动的垂直强度特征;塔克拉玛干沙漠扬沙和沙尘暴雷达等效回波强度约为-3～10 dBZ，浮尘等效回波强度约为-15～-3 dBZ;水平风垂直切变以及低空东风的维持是此次沙尘天气发生的动力成因。扬沙、沙尘暴发生时，大气垂直速度表现为上升运动，在较大水平风速及干燥下垫面的配合下，导致地面沙粒被输送到高空，形成了沙尘天气。

The Urumqi Institute of Desert Meteorology of China Meteorological Administration (CMA) carried out an atmospheric scientific experiment on the detection of dust weather using a wind profiler radar in the hinterland of the Taklimakan Desert in April 2010. Based on the wind profiler radar data obtained from this experiment, this paper analyzes the characteristics of the horizontal wind field and vertical velocity of a breaking dust weather in a desert hinterland, calculates and gives the radar echo intensity and vertical distribution of a dust storm, blowing sand and floating dust weather, and discusses the atmospheric dust counts/concentration derived from the wind profiler radar data. Studies show that a wind profiler radar is an upper air atmospheric remote sensing system that effectively detects and monitors dust. It captures the beginning and ending of a dust weather process as well as monitors the sand and dust being transported in the air in terms of height, thickness and vertical intensity. The echo intensity of a blowing sand and dust storm weather episode in Taklimakan is about -3~10dBZ while that of floating dustis -15~-3 dBZ, indicating that the dust echo intensity is significantly weaker than that of precipitation while stronger than that of clear air.
