摘　　要：本文利用青岛与台州的L波段雷达探空数据对两地稳定大气边界层(SBL)、中性大气边界层(NRL)和对流大气边界层(CBL)的特征进行了分析,探究SBL和CBL两种类型边界层的稳定性、湍流以及湿度层结特征。利用CFSR再分析数据对不同类型的边界层进行合成分析后发现,青岛与台州的稳定边界层发生时几乎均处在异常高压后部,异常低压前部,有异常南风,对流边界层的发生处在异常高压前部,异常低压后部,有异常北风。In this paper, the atmospheric boundary layers at Qingdao and Taizhou were divided into three categories. Then L-band sounding radar data was used to analyze the boundary layer characteris tics of stable boundary layer （SBI.） and convective boundary layer （CBI.）, and to explore the stability,turbulence and humidity characteristics of the different types of boundary layer. Though synthetic anal- ysis of CFSR data for different types of boundary layers of Qingdao and Taizhou, it is found that theslable boundary layers of Qingdao and Taizhou occurred almost all in rear of abnormal high pressure or in front of low pressure, there were abnormal southerly winds. Convective boundary layers occur infront of the abnormal high pressure or the rear of abnormal low pressure, there were abnormal northern winds.
