Abstract
We consider HOMME-NH, a variable-resolution, efficient and architecture-aware, non-hydrostatic dynamical core that is being developed under DOE’s earth system modeling initiative. With the algorithmic improvements included in this model and the current availability of high-performance computing resources, we can now begin to perform idealized global atmospheric simulations at resolutions at which non-hydrostatic effects become significant. While we are interested in studying and understanding the opportunities and challenges that are presented by such a capability, our studies also serve to assist in debugging and further developing and refining the model itself.
