| 摘 要： | 室内水槽模拟是大气边界层研究的一种重要手段。利用室内模拟水槽对大气边界层的发展进行了模拟,通过处理平均温度廓线和光斑图像得到了对流边界层顶部位置h2和边界层高度zi。结果表明,不同测量方法得到的结果一致性很好,与实际大气的边界层发展情况也较为接近。同时,根据试验情况确定初始条件和边界条件,使用边界层参数化模型进行了数值模拟,其结果与室内模拟的结果也较吻合。

| Abstract: | The laboratory simulation in the water tank is an important way in the study of convective boundary layer(CBL).In this paper,we simulate the evolution of atmospheric CBL in the water tank,and obtained the position of CBL top h_2 and CBL depth z_i from average temperature profiles and faculae picture.The results from different measurement methods accord with well,and give a good agreement with the situations from the atmospheric CBL.Then,the results of numerical simulation by using parameterization models of CBL,with the initial and boundary conditions obtained from the data of water tank,fit the result from water tank quit well. |
