Earlier versions of this model were described for flow over complex terrain; however, these earlier versions treated stratification with a simplified buoyancy forcing term and did not explicitly take into account hydrostatic pressure gradients. The latest version of this model more accurately computes the density effects by removing the buoyancy term and adding a horizontal pressure gradient force that arises from the hydrostatic component of pressure. This representation, more accurately captures gravity-driven flows and internal waves. Furthermore, the pressure solver was updated to a multigrid solver, to allow for a lower computational cost. GCCOM has also demonstrated the ability to nest within a regional hydrostatic model, allowing for the efficient simulation of multiscale processes, and it includes a data assimilation framework.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">In this contribution, we focus on the validation of the nonhydrostatic capabilities of the model in a stratified environment. In particular, we use a suite of test cases widely used as benchmarks for assessing the nonhydrostatic capabilities for gravity-driven flows and internal waves. The numerical experiments include an internal seiche, a lock release, and a tidally-forced stratified flow over a seamount aimed at investigating the formation of internal wave beams. Our results collectively demonstrate the accuracy of GCCOM for these types of flows. </div><div><br></div></div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">Sponsored by the SDSU-SIAM Student Chapter</div><div><br></div>-- <br><div class="m_719462959072640588m_-4573244273343164134gmail_signature">
