摘要：

Constant sets for several turbulence closure models, based on data for the atmospheric boundary layer, are proposed. They differ from those currently used in engineering situations but are self-consistent and tuned to represent atmospheric boundary-layer turbulence. The proposed constant sets are tested in a simple, one-dimensional, neutrally-stratified planetary boundary-layer flow over a horizontally homogeneous and aerodynamically rough flat surface. Comparisons of model results with similarity theory and large-eddy simulation show promise for improving boundary-layer predictions.
