Book excerpt: The U.S Navy has a strong interest in conducting atmospheric research in support of operational mesoscale forecasts used to derive atmospheric conditions deemed of strategic interest within the littoral. This effort will require relatively fine horizontal resolution (generally less than 10 km) to accurately represent the complex flow and thermodynamic conditions which typically reside near the coastal regions of the globe. The task is made even more difficult by the need to produce the required high resolution products within an operationally viable time frame. It is toward this end that the Naval Research Laboratory, in collaboration with the High Performance Computing Section of the National Oceanic and Atmospheric Administration's Forecasts Systems Laboratory (NOAA FSL), has embarked on developing a parallel version of the Coupled Oceanic Atmospheric Mesoscale Prediction System (COAMPS, Hodur 1997). The COAMPS is a nonhydrostatic fully compressible finite difference model which uses the Arakawa-C grid stagger. The purpose of this paper is to provide a brief overview of the effort to parallelize COAMPS together with two examples illustrating the naval need for parallel computational capability.
