Modified Dynamic Mixed Subgrid-scale Models for Geophysical Flows: Forced Two-Dimensional and -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…
Evaluation of Analytical Turbulence Closures for Quasi-Geostrophic Ocean Flows with Coastal Boundaries
Anantha Narayanan Suresh Babu, Akhil Sadam, Pierre F. J. Lermusiaux
Numerical turbulence simulations typically involve parameterizations such as Large Eddy Simulations (LES). Applications to geophysical flows, especially ocean flows, are further co…
Guided Unconditional and Conditional Generative Models for Super-Resolution and Inference of Quasi-Geostrophic Turbulence
Anantha Narayanan Suresh Babu, Akhil Sadam, Pierre F. J. Lermusiaux
Typically, numerical simulations of Earth systems are coarse, and Earth observations are sparse and gappy. We apply four generative diffusion modeling approaches to super-resolutio…
