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…

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…
