摘　　要：2021年4月15至16日石家庄市出现一次沙尘污染过程,致使石家庄市颗粒物浓度短时间内大幅飙升。本文利用石家庄市预测预报中心大气复合污染及灰霾监测超级站的资料,对本次沙尘污染过程进行分析。此次沙尘过程受高空低涡和蒙古气旋东移影响,15日下午沙尘气团抵达京津冀及周边区域,石家庄地区出现大范围扬沙或浮尘天气。致使石家庄市颗粒物爆表9个小时,空气质量达到重度污染。之后受沙尘过境后浮尘影响,我市PM_(10)浓度偏高,严重影响石家庄市空气质量。A dust pollution event in Shijiazhuang on April 15-16 in 2021 sent particle concentrations in Shijiazhuang soaring in a short period of time.In this paper,the dust pollution process was analyzed using the Shijiazhuang Prediction and Forecasting Center’s air pollution and Haze Monitoring Super Station.The dust was affected by a high-altitude vortex and the eastward movement of the Mongolian cyclone.The dust reached the Beijing-tianjin-hebei region and the surrounding areas on the afternoon of May 15,and there was a large-scale dust blowing or floating dust weather in the Shijiazhuang region.It caused Shijiazhuang’s particulate matter to explode for nine hours,and the air quality reached a high level of pollution.After the dust after the impact of floating dust,the city’s high PM_(10) concentration,seriously affecting Shijiazhuang’s air quality.
