Super-Micro Computer Weather Prediction Model

Abstract

A meso-beta scale model is being developed to provide forecast guidance in the 3 to 18 h time period. The model is intended for use at local base weather offices equipped with a super-mirco class computer, allowing these offices to produce local forecast guidance for their region. The model consists of five layers, the lowest of which represents the evolving boundary layer. A specially developed vertical coordinate is used that allows the model to dynamically adjust to changes in boundary-layer height so that the thickness of the lowest layer increases and decreases as the boundary layer grows and shrinks. This allows a fairly simple boundary-layer parameterization to be used that realistically simulates boundary-layer processes. This report presents the model equations for the dynamic model, including their derivation and energy conserving finite difference representation. The physical parameterizations were presented in an earlier report, so only changes compared to that previous presentation are included here. This report also presents the results from a variety of test simulations of the model and physical parameterizations. (Author)
