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…
Extreme vertical drafts as drivers of Lagrangian dispersion in stably stratified turbulent flows
Christian Reartes, Pablo D. Mininni, Raffaele Marino
The dispersion of Lagrangian particle pairs is a fundamental process in turbulence, with implications for mixing, transport, and the statistical properties of particles in geophysi…
Energy cascades in rotating and stratified turbulence in anisotropic domains
Alexandros Alexakis, Raffaele Marino, Pablo D. Mininni
The concept of inverse energy cascades has played a central role in the development of turbulence theory, with applications in two-dimensional and quasi-two-dimensional flows. We e…
Large-scale self-organisation in dry turbulent atmospheres
Alexandros Alexakis, Raffaele Marino, Pablo D. Mininni +3
How turbulent convective fluctuations organise to form large-scale structures in planetary atmospheres remains a question that eludes quantitative answers. The assumption that this…
Multi-Particle Dispersion in Rotating-Stratified Turbulent Flows
Sebastian Gallon, Fabio Feraco, Raffaele Marino +1
The transport of matter by turbulent flows plays an important role, in particular in a geophysical context. Here, we study the relative movement of groups of two (pairs) and four (…
Lagrangian irreversibility and energy exchanges in rotating-stratified turbulent flows
Sebastian Gallon, Alessandro Sozza, Fabio Feraco +2
Turbulence in stratified and rotating turbulent flows is characterized by an interplay between waves and eddies, resulting in continuous exchanges between potential and kinetic ene…
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…
Inverse cascades and resonant triads in rotating and stratified turbulence
D. Oks, P. D. Mininni, R. Marino +1
Kraichnan seminal ideas on inverse cascades yielded new tools to study common phenomena in geophysical turbulent flows. In the atmosphere and the oceans, rotation and stratificatio…
Evidence for Bolgiano-Obukhov scaling in rotating stratified turbulence using high-resolution direct numerical simulations
D. Rosenberg, A. Pouquet, R. Marino +1
We report results on rotating stratified turbulence in the absence of forcing, with large-scale isotropic initial conditions, using direct numerical simulations computed on grids o…
Geophysical turbulence and the duality of the energy flow across scales
A. Pouquet, R. Marino
The ocean and the atmosphere, and hence the climate, are governed at large scale by interactions between pressure gradient, Coriolis and buoyancy forces. This leads to a quasi-geos…
