  • September 24, 2014: Stochastic parameterization of QG flows
    Ian Grooms ( NYU Courant Institute of Mathematical Sciences)
    Stochastic superparameterization (SP) is a multiscale framework for the development of stochastic parameterizations. This talk reviews the recent development and application of stochastic SP to mesoscale ocean eddy parameterization in coarse and eddy-permitting quasigeostrophic models. A main feature of the method is the inclusion of stochastic backscatter, which leads to increased model variability. The method is tested in a doubly-periodic `eddy-permitting' setting, where the model grid scale resolves the peak of the kinetic energy spectrum but not the deformation radius, and in a coarse-resolution channel model with complex topography. In the eddy permitting setting the stochastic backscatter parameterizes the inverse cascade of kinetic energy from unresolved scales, and is crucial for accurate representation of large-scale dynamics. In the channel model the primary impact of the method is increased temporal variability, though the variability remains too low overall. A path towards implementation in primitive equation models is sketched at the end.
