摘　　要：利用多源观测数据,对2018年3月28日石家庄市出现的一次沙尘污染过程进行分析。结果表明沙尘源来自西北方向蒙古国的中北部,受东北回流影响沿东北-西南路径传输至石家庄;沙尘污染过程与气象要素关系密切,沙尘天气可着重关注风速风向,预判沙尘过境时间;沙尘过境时,消光系数与退偏比可对沙尘气溶胶天气进行监测分析,对沙尘的预报预警具有一定指示意义;湍流强度对沙尘的发生发展有较好的预警作用。Using multi-source observational data,this study analyses the dust pollution process that occurred in Shijiazhuang City on March 28,2018.The results show that:The source of dust pollution in Shijiazhuang on March 28,2018 came from the northwest of the central and northern part of Mongolia.It moved to the northeastern part of Hebei Province and was affected by the northeast return.The sand and dust pollution process is closely related to meteorological elements.The sand and dust weather can focus on wind speed and direction,and predict the transit time of sand and dust.The extinction coefficient of the aerosol lidar can detect and analyze the dust and aerosol weather,and has certain indication significance for the forecast and early warning of dust and dust.The intensity of turbulence has a good early warning effect on the occurrence and development of sand and dust.
