Modified Dynamic Mixed Subgrid-scale Models for Geophysical Flows: Forced Two-Dimensional and $\beta$-plane Turbulence

Anantha Narayanan Suresh Babu, Akhil Sadam, Pierre F. J. Lermusiaux

Subgrid-scale (SGS) models for large-eddy simulations (LES) of geophysical turbulence typically need to balance dissipative regularization with backscatter, the upscale transfer of…
