Simulation Research for PBL using Non-Local Closure over Complex Underlying Surface Domain
复杂下垫面模拟域大气边界层非局地闭合模拟研究

A new closure method based on the transilient turbulence theory developed by Stull is studied, and the results show that the transilient turbulence theory is proper and may have broader applications to atmospheric boundary layer modeling and other models Based on the transilient turbulent theory a non-local closure 2-D model was conducted to simulate the atmospheric advection between oasis and sand and the results show that the model can be successful to simulate oasis-sand region thermal internal boundary layer such as moisture inversion, oasis cold island effect
