摘要
本文叙述一些数值预报模式中大气边界层的处理。着重讨论大气边界层模式和自由大气模式的耦合、混合层的演变、表面层参数化、卷夹的参数化以及湿热力过程和辐射的作用。指出大气边界层的处理对海洋环境数值预报的重要性。
In this paper,the methods used for representing the atmospheric boundary layer in some numerical forecast models are described.The emphases are placed on the discussion of the coupling of the atmospheric boundary layer model with a free atmospheric model,the evolution of the mixed layer,the surface layer parameterization,the entrainment parameterization and the effects of moisture and radiation in the atmospheric boundary layer model.It is shown that a realistic representation of the atmospheric boundary layer is of great importance to numerical marine environment forecasts.
