摘  要:
利用近地面观测仪器,对2009年3月11日民勤治沙站3号塔监测站沙尘暴过程近地层气象要素变化特征及其与沙尘暴强度之间的关系进行了分析;同时分析了沙尘暴过程中PM10的变化特征。结果表明,西西伯利亚冷锋是形成这次沙尘暴的主要原因;温度、压强、湿度和风速变化均与沙尘暴的强度密切相关;PM10与沙尘暴的强度之间有很好的对应关系,沙尘暴时段PM10最大值为2.279mg/m3。

摘  要:
Using near-surface observation instrument,the formation process of sandstorm occurred on March 11,2009 at Sand Point No.3 tower in Minqin and the relationship between the sandstorm intensity and meteorological elements variation were analyzed;also the process of PM10 dust storms of the variation was analyzed.The results showed that the West Siberian cold front was the main reason for the formation of the dust storms;temperature,pressure,humidity and wind speed changes were all closely related to the intensity of dust storms;PM10 and the intensity of dust storms had a good correlation,in the processing of the dust storms occurrence,the maximum value of PM10 was 2.279mg/m3.
