Scaling laws and local enhancements of buoyancy flux in stratified turbulent flows
Gyeongseob Song, Fabio Feraco, Raffaele Marino +6
In the presence of stratification, turbulent flows exhibit intermittency not only at small scales but also at large scales, comparable to the mean flow, as observed in the atmosphe…
Helicity subgrid-scale models and their numerical validation
Nobumitsu Yokoi, Pablo D. Mininni, Annick Pouquet +2
Large-eddy simulations (LES) with an appropriate subgrid-scale (SGS) model provide a powerful tool for investigating real-world turbulence. The Smagorinsky model, one of the simple…
Connecting Large-Scale Velocity and Temperature Bursts with Small-Scale Intermittency in Stratified Turbulence
Fabio Feraco, Raffaele Marino, Leonardo Primavera +13
Non-Gaussian statistics of large-scale fields are routinely observed in data from atmospheric and oceanic campaigns and global models. Recent direct numerical simulations (DNSs) sh…
Turbulence generation by large-scale extreme vertical drafts and the modulation of local energy dissipation in stably stratified geophysical flows
Raffaele Marino, Fabio Feraco, Leonardo Primavera +4
We observe the emergence of strong vertical drafts in direct numerical simulations of the Boussinesq equations in a range of parameters of geophysical interest. These structures, w…
Coupling large eddies and waves in turbulence: Case study of magnetic helicity at the ion inertial scale
Annick Pouquet, Julia E. Stawarz, Duane Rosenberg
In turbulence, for neutral or conducting fluids, a large ratio of scales is excited because of the possible occurrence of inverse cascades to large, global scales together with dir…
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,…
