Deep Mixed Layer in Northwest China Dry Area in Summer Half Year and Formation of the Dry Climate
西北干旱区夏半年深厚的混合层与干旱气候形成

To better understand the features of distribution and variation of the atmospheric mixed layer depth(hereafter ML) and the impact of the deep ML on the dry climate over Northwest China(NWC),in this paper,the ML thickness,its change,and the impact of it on the NWC dry climate formation have been calculated and analyzed,utilizing the observed sounding data in Zhangye and Minqin in summer and related months in more years.The main conclusions are as follows:(1) There are clear annual changes and inter-local dif...
