Joint downscale fluxes of energy and potential enstrophy in rotating stratified Boussinesq flows
Turbulent ows Stratied ows Rotating ows
2011/10/14
We employ a coarse-graining approach to analyze nonlinear cascades in Boussinesq flows using high-resolution simulation data. We derive budgets which resolve the evolution of energy and potential enst...
