Isolation and implementation of the dynamical core from the German Weather Service's numerical weather prediction model

Isolation of the dynamical core from the German Weather Service's (Deutscher Wetterdienst) numerical weather prediction model forms the basis of an experimental framework for dynamical simulations up to 300 km in altitude. This requires an understanding of the primitive equations of meteorology, the numerical method behind their solution and running the model on NCAR's (National Center for Atmospheric Research) parallel computers. From here, various physical parameterizations such as friction and radiation can be "turned off" and replaced with a simple idealized forcing and dissipation. This results in a mechanistic dynamical model that can be used to investigate amplifcation/dissipation of various waves in the middle (20--100 km) and upper (> 100 km) atmosphere at higher spatial and temporal resolutions than current global climate models (GCMs) allow. The model is also formulated for easy modification for multi-planet applications.
