Abstract : Some authors have shown that in China, the contribution to the height tendency of an isobaric surface due to surface friction is of the same order of magnitude as that of largescale topographic influences, and that under certain special weather conditions, non-adiabatic heating must be taken into account, even in short-range forecasting. Considering these effects, this paper first derives a two-parameter baroclinic model suitable for numerical weather prediction by combining the hydrodynamic and thermodynamic equations and then solves the system of prognostic equations. The truncation errors in numerical weather prediction when a triangular grid-point system is used are discussed, and an optimum formula for the field is derived. Finally, the paper discusses briefly the problem concerning the development of large-scale baroclinic disturbances. (Author)
