Abstract:The atmospheric boundary layer plays a critical role in the exchanges of heat, momentum, and matter between the underlying earth surface and free atmosphere, as well as in balancing global radiation. Numerical models need the parameterization scheme to simulate the boundary layer. In this paper, common boundary layer parameterization schemes in numerical models are reviewed. These schemes are summarized from closed frames and important physical processes in the boundary layer. The development directions of boundary layer parameterization schemes are also discussed.
