A Candidate Mesoscale Numerical Cloud/Precipitation Model.
Abstract
A numerical mesoscale forecast model was selected for potential use by the Air Force in an operational mode, either in a nested configuration, or as a stand-alone model in a base-weather station. The model was developed at the National Oceanographic and Atmospheric Association's (NOAA) Environmental Research Laboratory (ERL), and many of its numerical and meteorological features are described in this report. Two versions are specified: the first under development at NOAA/ERL and another at AFGL (the NOAA/AFGL model). A baseline test of the latter model revealed several problems. The initialization scheme computed initial fields of mass and momentum that failed to mutually adjust after several hours of integration. Subsequent techniques designed to improve the initial conditions appeared to be a step in the right direction. The nonmeteorological gravity-inertia wave noise evident in most of the forecast fields appeared to result from poor treatment of the variables at the lateral boundaries.
