Current and Future Development of a Non-hydrostatic Unified Atmospheric Model (NUMA)

Abstract

Our goal is to construct numerical methods for non-hydrostatic mesoscale and global atmospheric models (for NWP applications); this is a unified model. The reason for this is economics - one (production) model is cheaper to support or at the very least, having the same dynamics simplifies a great many things (e.g. training future developers). Our aim is to build a modeling framework with the following capabilities: 1. Highly scalable on current and future computer architectures (exascale computing and beyond and GPUs) 2. Flexibility to use a wide range of grids (e.g., statically and dynamically adaptive) 3. Global model that is valid at the meso-scale (i.e., non-hydrostatic) 4. NUMA Framework to include: * A suite of time-integrators (explicit, semi-implicit, fully-implicit) * Various numerical methods (SE/DG) * Various forms of the Governing Equations to determine what form is more accurate, efficient, robust.
