摘要
采用自动气象站观测资料、常规micaps资料等,对2016年春季塔里木盆地的一次沙尘天气过程展开分析。结果表明:西西伯利亚冷高压东移南下和塔里木盆地一带热低压的强烈发展是本次塔里木沙尘天气发生的主要影响系统。持续稳定较高的气压梯度和气温异常偏高为塔里木盆地的沙尘天气过程提供了较好的动力以及热力条件。沙尘天气发生过程中,塔里木盆地东部低层主要为偏东、东北风,高空急流的强烈抽吸以及近地层较强东北风的共同作用,对塔里木盆地塔中、若羌、铁干里克、轮台、且末发生强沙尘暴提供了有利条件。在沙尘天气期间,逆温层温度梯度较大,极易形成不稳定层结,促使了沙尘暴天气的形成。
This article mainly uses automatic weather station observation data,conventional micaps data and other related data to analyze a sand and dust weather process in the Tarim Basin in the spring of 2016.The results showed that the cold high pressure in West Siberia moved eastward to the south and the intense development of thermal low pressure in the Tarim Basin was the main impact system of this sandstorm in Tarim.The continuous and stable high pressure gradient and abnormally high temperature provide better power and thermal conditions for the sand and dust weather process in the Tarim Basin.During the occurrence of dusty weather,the lower layers in the eastern part of the Tarim Basin are mainly easterly and northeasterly winds,the strong suction of high-altitude jets and the strong northeasterly winds near the surface have a combined effect on Tazhong,Ruoqiang,and Tieganlik in the Tarim Basin.The occurrence of strong sandstorms in Luntai and Qiemo is very favorable.During the sand and dust weather,the temperature gradient of the temperature inversion layer is relatively large,and it is easy to form unstable stratification,which promotes the formation of sand and dust storms.
