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…
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…
