Abstract:
Experiments were carried out to find means of improving the forecast performance of the Air Force Global Weather Central AFGWC Boundary Layer Model. The results suggest that modifications in the methods of estimating eddy diffusivity and surface specific humidity may yield a slight improvement in the forecast accuracy while requiring less computation. It is also demonstrated that doubling the time step from 30 to 60 min does not significantly degrade the forecast accuracy. Suggestions on further modifications under less restrictive operational conditions are also included. Author
