Energy transfer in rotating stratified turbulent flows

Abstract:

When including rotation and stratification non-linear interactions in turbulent flows occur both at small scales, with turbulent mixing and dissipation, as well as at large scales where accumulation of energy can take place through an inverse cascade. We present a characterization of the energy transfer across the scales in rotating and/or stratified turbulent flows showing how the spectra and fluxes in the Fourier space depend on the relative strength between rotation and stratification.
