A Brief Overview of Mesoscale Numerical Modeling for the Earths Polar Regions as of 2018
Abstract
This report is an attempt to provide a quick review of the current state of mesoscale numerical weather prediction modeling over polar regions of the Earth. These areas are notoriously difficult for both models and human forecasters due to their complexities of terrain, energy budget, ice-albedo feedback, and cloud microphysics (to name just a few). Although both global and mesoscale numerical weather prediction models have become increasingly sophisticated over the last several decades and in step with phenomenal increases in computational power, unique modifications still have had to be developed for their proper application to polar regions of the globe. Even in lieu of these improvements and specialized modifications, there remain a number of challenges and deficiencies to be addressed for more skillful use over polar regions, including for short-range forecasting and nowcasting purposes (which are of great interest to the US Army and other US Armed Forces).
