Super-Micro Computer Weather Prediction Model

Abstract

A meso-beta scale model is being developed to provide forecast guidance in the 3 to 18 hour time period. The model is intended for use at local base weather offices equipped with a super-micro class computer, allowing these offices to produce local forecast guidance for their region. The model consists of a four-layer sigma-coordinate model which has a two-layer boundary layer model nested within its lower layer. The vertically nested two-layer model allows direct calculation of boundary layer quantities through simple parameterizations for radiative processes and surface fluxes. The model has a 480 x 480 km horizontal domain with 20 km resolution which is nested horizontally, using a two-way interactive procedure, within a 1320 x 1320 km coarse grid domain with 60 km resolution. This reports presents the equation sets for the nested model and the physical parameterizations. It also summarizes tests of the nested four-layer/two-layer model structure which have been completed, and separate tests of the parameterization package. (KR)
