ENERGY TRANSFER IN ROTATING STRATIFIED TURBULENT FLOWS etc15 Tracking Number 440Presentation: Session: Atmospheric turbulence 3 Room: Room C Session start: 10:30 Wed 26 Aug 2015 Raffaele Marino marino@ucar.edu Affifliation: National Center for Atmospheric Research Annick Pouquet pouquet@ucar.edu Affifliation: National Center for Atmospheric Research Duane Rosenberg duaner62@gmail.com Affifliation: Oak Ridge National Laboratory Pablo Mininni mininni@df.uba.ar Affifliation: Universidad de Buenos Aires Topics: - Atmospheric turbulence, - Geophysical and astrophysical turbulence, - Intermittency and scaling 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. |
