摘要
利用通辽气象观测站高空探测资料、地面常规观测资料和沙尘暴监测资料,对2012年3月29日通辽市沙尘暴天气过程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,并分析了沙尘暴过程中pM_(10)浓度变化特征。结果表明:蒙古气旋和冷锋是形成这次沙尘暴的主要原因,高空和近地面的风速、风向、温度、湿度及气压变化均与沙尘暴的强度密切相关,pM_(10)浓度与沙尘暴的强度之间有很好的对应关系,强沙尘暴时pM_(10)浓度最大值为13548.8 ug·m^(-3)。
Using the sounding data,surface conventional observation data and dust storm monitoring data,the changes ofmeteorological elements and its relationship with the intensity of sandstorm were analyzed on March 29,2012 in Tongliao station.As while the variation characteristics of PM10 mass concentration during the sandstorm were analyzed.The results showed thatthe Mongolia cyclone and cold front were the main reasons for the formation of the sandstorm;The changes of wind speed anddirection,temperature,humidity and pressure at the upper layer and near-ground were closely related to the intensity of sandstorm.The mass concentration of PM10 and the intensity of sandstorm had a good correlation.The maximum concentration of PM10 was13548.8ug·m-3 in the strong sandstorm process.
