Using High-Order Element-based Galerkin Methods to Capture Hurricane Intensification

Explore cutting-edge research on hurricane rapid intensification modeling in this seminar presented by Frank Giraldo from the Naval Postgraduate School. Delve into the challenges of capturing hurricane intensification at LES-type scales and discover how element-based Galerkin Methods are being utilized to approximate spatial derivatives. Learn about innovative time-integration strategies, including process Multirate methods and a multi-modeling framework (MMF) designed to replace physical parameterizations in weather and climate models. Examine the application of Variational Multi-Scale (VMS) methods to provide a rigorous mathematical foundation for MMF, aimed at better resolving hurricane inner cores. Gain insights into flux differencing discontinuous Galerkin Methods for constructing Kinetic Energy Preserving and Entropy Stable methods, and understand the importance of scalable models in achieving research goals. Get an overview of NUMA, a 3D nonhydrostatic atmospheric model capable of running on large CPU clusters and GPUs, and its potential impact on hurricane modeling.
