中文摘要	基于气象条件、激光雷达、风场和HYSPLIT轨迹模型等多源资料,综合分析了2019年3月26-28日发生在甘肃省的一次强沙尘暴天气过程,全面研究其发生发展、时空分布和垂直结构特征以及主要来源和传输路径。结果表明:(1)高空横槽是引起此次沙尘暴天气的关键因子。此次沙尘起源于塔克拉玛干沙漠,自西向东影响到甘肃省,使部分城市环境空气质量转为严重污染。(2)此次沙尘传输路径位于甘肃省以北地区,沙尘在东移过程中沉降明显,在传输过程中颗粒物浓度不断降低。通过分析沙尘传输时间可为下游城市空气质量预报提供参考。(3)对于荒漠半干旱地区,在风速较小的条件下也可能出现强沙尘天气。研究表明地基激光雷达观测资料能较好地分析沙尘暴天气的垂直发展过程,对沙尘的传输路径及沙尘来源均具有很好的指示意义。
英文摘要	Based on multiple data such as synoptic data, HYSPLIT, lidar and wind data, a severe sandstorm process in Gansu Province, China, from March 26 to 28, 2019 is comprehensively analyzed, and its occurrence, development, temporal and spacial variation, vertical structure features as well as the source and transport path of the sandstorm. The results show that, (1) the horizontal trough at upper level is the key factor causing the sandstorm. The sandstorm originated from the Taklimakan Desert and affected Gansu Province from west to east, resulting in serious air pollution in several downstream cities. (2) The dust transport path reached the north of Gansu Province, and there was obvious sedimentation during the eastward movement of the dust, resulting in the continuous reduction of dust concentration in the process of transport. It is shown that the analysis of dust transport time can provide reference for the air quality prediction in downstream cities. (3) For the semi-arid desert areas, strong dust may also occur even when the wind speed is small. The results of this study indicate that the ground-based lidar products can not only be used to analyze the vertical development of the sandstorm, but also act as a good indicator for the transport path and source of the sandstorm.
