摘要：采用索尔比扬（Sorbjan）提出的一种参数化方法，推导出对流边界层中垂直速度、位温以及湿度（或被动标量浓度）的各种统计矩的表达式。该方法基于将统计矩分解为非穿透分量和剩余分量，并对它们进行局地（依赖高度）尺度分析。将所得表达式与大气和实验室数据以及大涡模拟模型的结果进行了比较。相似性函数与实验数据之间取得了一致性。
Abstract A parameterization method developed by Sorbjan is used to derive expressions for various statistical moments of vertical velocity, potential temperature, and humidity (or passive scalar concentration) in the convective boundary layer. The method is based on decomposing statistical moments into nonpenetrative and residual components, and their local (height-dependent) scaling. The resulting expressions are compared with atmospheric and laboratory data, and also with the results of large-eddy simulation models. An agreement between the similarity functions and the experimental data is obtained.
