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 (…
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…
Efficient kinetic Lattice Boltzmann simulation of three-dimensional Hall-MHD Turbulence
Raffaello Foldes, Emmanuel Lévêque, Raffaele Marino +4
Simulating plasmas in the Hall-MagnetoHydroDynamics (Hall-MHD) regime represents a valuable {approach for the investigation of} complex non-linear dynamics developing in astrophysi…
Direct observational evidence of an oceanic dual kinetic energy cascade and its seasonality
Dhruv Balwada, Jin-Han Xie, Raffaele Marino +1
The Ocean's turbulent energy cycle has a paradox; large-scale eddies under the control of Earth's rotation primarily transfer kinetic energy (KE) to larger scales via an inverse ca…
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…
Single-particle Lagrangian statistics from direct numerical simulations of rotating-stratified turbulence
Dhawal Buaria, Alain Pumir, Fabio Feraco +4
Geophysical fluid flows are predominantly turbulent and often strongly affected by the Earth's rotation, as well as by stable density stratification. Using direct numerical simulat…
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…
