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…
Numerical simulations of waves and turbulence in coronal loops: observables and spectra
Fabio Feraco, Francesco Pucci, Claudio Meringolo +11
We investigate numerically the time evolution of velocity and magnetic field fluctuations in a coronal loop, focusing on the dynamics due to both phase mixing and turbulent cascade…
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 (…
