Data-driven stochastic spectral modeling for coarsening of the two-dimensional Euler equations on the sphere

Sagy Ephrati, Paolo Cifani, Milo Viviani +1

A resolution-independent data-driven stochastic parametrization method for subgrid-scale processes in coarsened fluid descriptions is proposed. The method enables the inclusion of…

Sparse-stochastic model reduction for 2D Euler equations

Paolo Cifani, Sagy Ephrati, Milo Viviani

The 2D Euler equations are a simple but rich set of non-linear PDEs that describe the evolution of an ideal inviscid fluid, for which one dimension is negligible. Solving numerical…
