A limited area seven layer physical-numerical model for the lower tropospheric region is described. The grid interval is half that of the standard numerical weather prediction grid used in the hemispheric, free atmospheric operational model at the Air Force Global Weather Central AFGWC. This model is an integral part of the complete AFGWC meso-scale sub-synoptic numerical analysis and prediction system. This model provides greater horizontal and vertical resolution in both the numerical analyses and numerical forecasts. It is used to predict the more detailed smaller scale atmospheric perturbations which are important in specifying sensible weather elements. Important features of this boundary layer model include a completely automated objective numerical analysis of input data the transport of heat and moisture by three dimensional wind flow including terrain and frictionally induced vertical motions latent heat exchange in water substance phase changes and eddy flux of heat and water vapor.
