An Efficient Numerical Model of the Planetary Atmospheric Boundary Layer. SEP 1977
Authors:  Tsann-Wang Yu; Darrell Strobel; NAVAL RESEARCH LAB WASHINGTON D C
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.This paper presents an efficient two-dimensional time-dependent one-layer boundary layer model designed specifically for use in general circulation models. Two fundamental problems associated with the boundary layer parameterization are examined using the one-dimensional version of the model. These are the effects of different PBL parameterization schemes and different flux profiles on the model wind and temperatures. This paper concludes that the effect of different PBL parameterization is very significant on ...

Comments on Certain Boundary Layer Parameterization Schemes Used in Atmospheric Circulation Models. JUL 1977
Authors:  Tsann-Wang Yu; Rao Madala; NAVAL RESEARCH LAB WASHINGTON D C
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.This paper discusses two important processes of boundary layer parameterization for use in general circulation models (GCM). The first process, based on the surface constant flux layer theory, is applicable when the first level of a GCM is placed below the surface layer. The second one, based on the Rossby number similarity and generalized similarity theories, is appropriate when the first level of a GCM is above the entire boundary ...
