较系统地阐述了中尺度运动对大尺度模式网格平均的次网格通量的影响方式和作用机制,提出了在大尺度模式中参数化次网格中尺度通量和地表次网格通量中尺度加强的思想方法,初步分析了这些参数化方法的缺陷和局限性,对几个在参数化中尺度通量和地表次网格通量中尺度加强时应重点考虑的关键因子提出了建议。最后,讨论了参数化非均匀大气的网格平均的次网格通量的一些新的想法及相关问题。

The influence of mesoscale motion on grid-averaged subgrid-scale fluxes of large-scale model is systematically expounded.The ideas of parameterization of mesoscale fluxes and surface subgrid-scale fluxesare presented. The defects of the present parameterization are preliminarily analyzed. The key factors to be considered for parameterizing the mesoscale fluxes and surface subgrid-scale fluxesare suggested. Finally, the new ideas and questions on parameterization of grid-averaged subgrid-scale fluxesof atmosphere of heterogeneous large-scale grid are discussed.
