摘要
2021年,中国北方地区经历了多轮大范围沙尘天气,波及西北、华北、东北甚至黄淮、长三角等地区。其中,3月份出现自2010年以来最强沙尘天气过程。该研究基于Himawari-8静止卫星数据和地面同步空气站点监测数据,分析了2021年3月14—17、27—30日和4月14—15日3次典型沙尘天气过程。分析结果显示:2021年3月14—17日沙尘天气影响范围最广,沙尘分别在不同时间段起源于蒙古国西北部、中国甘肃和青海交界处、新疆和甘肃交界处,大范围沙尘天气是多处尘源综合作用的结果。3月27—30日和4月14—15日沙尘主要起源于蒙古国,沙尘源较单一,影响范围相对集中,但某些时段受影响区域的沙尘强度很高。地面同步空气站点PM_(10)监测数据与卫星数据有很好的一致性。
In 2021,the northern China experienced several rounds of large-scale dust weather,affecting the northwest,north and northeast China,even Huanghuai River,Yangtze River Delta and other regions,the strongest dust weather process in nearly 10 years occurred in March.Based on the Himawari-8 data and the monitoring data of the ground air station,this paper analyzed three typical dust weather processes form March 14 to 17,March 27 to 30 and April 14 to 15 in 2021.The results showed that the dust weather happened from March 14 to 17 had the widest influence range.The dust originated from the northwest of Mongolia,the junction of Gansu and Qinghai,and the junction of Xinjiang and Gansu in different time periods.The large-scale dust weather was the result of the comprehensive action of multiple dust sources.The dust weather happened form March 27 to 30 and April 14 to 15 mainly originated from Mongolia.The dust source was relatively single and the influence range was relatively concentrated,but the dust intensity was very high in some periods.The PM_(10)monitoring data of ground synchronous air station were in good agreement with the satellite data.
