Linking dissipation, anisotropy and intermittency in rotating stratified turbulence
A. Pouquet, D. Rosenberg, R. Marino
Analyzing a large data base of high-resolution three-dimensional direct numerical simulations of decaying rotating stratified flows, we show that anomalous mixing and dissipation,…

Helicity dynamics, inverse and bi-directional cascades in fluid and MHD turbulence: A brief review
A. Pouquet, D. Rosenberg, J. E. Stawarz +1
We briefly review helicity dynamics, inverse and bi-directional cascades in fluid and magnetohydrodynamic (MHD) turbulence, with an emphasis on the latter. The energy of a turbulen…

Vertical drafts and mixing in stratified turbulence: sharp transition with Froude number
F. Feraco, R. Marino, A. Pumir +4
We investigate the large-scale intermittency of vertical velocity and temperature, and the mixing properties of stably stratified turbulent flows using both Lagrangian and Eulerian…
