Adjoint-based online learning of two-layer quasi-geostrophic baroclinic turbulence

no code implementations21 Nov 2024 Fei Er Yan, Hugo Frezat, Julien Le Sommer, Julian Mak, Karl Otness

For reasons of computational constraint, most global ocean circulation models used for Earth System Modeling still rely on parameterizations of sub-grid processes, and limitations in these parameterizations affect the modeled ocean circulation and impact on predictive skill.

Data-driven multiscale modeling of subgrid parameterizations in climate models

no code implementations24 Mar 2023 Karl Otness, Laure Zanna, Joan Bruna

Subgrid parameterizations, which represent physical processes occurring below the resolution of current climate models, are an important component in producing accurate, long-term predictions for the climate.
