High-Order, Multi-Scale Ocean Modeling on Adaptive, Unstructured Meshes: Comparison of SEOM and ROMS in the Northwest Atlantic

Abstract

A novel oceanic test has revealed an interesting dynamical limit for the hydrostatic Navier-Stokes equation that argues against using high-order methods for simulating these types of flows. This strange behavior was uncovered largely due to the fidelity of the spectral element model to the mathematical setting of the hydrostatic equations. A non-hydrostatic version of the spectral element model has been produced that incorporates many of the advances developed in recent years; the model is currently being applied to simulating gravity currents at high Reynolds number. We have continued in our efforts to build an unstructured-grid ocean modeling community by organizing several national and international meetings where participants share their common experience in developing and running unstructured grid models.
