The modification of Equivalent Barotropic Model and A preliminary study of the Surface Boundary Layer Model

Abstract

　　The Equivalent Barotropic model, which is using by CAF Weather Central, is modified in two folds: adding the frictional and very long wave effects into the model, and the orographical effects which already included in the model is changed by using the surface wind (which is derived from the upper level wind) in calculation. Numerical experiments show that each effect has some contributions to the numerical prediction especially the long wave term.
　　In the second part of this report, the important features of the boundary layer medel are described. Also there are problems in developing this model, it can be solved in the future. And, for the purpose of Air Force operation, we think it is worth to develop this model into operation.
　　Some numerical results are presented in this paper.
