Single-particle Lagrangian statistics from direct numerical simulations of rotating-stratified turbulence

27 May 2020 Buaria Dhawal Pumir Alain Feraco Fabio Marino Raffaele Pouquet Annick Rosenberg Duane Primavera Leonardo

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 simulations of forced Boussinesq equations, we study the influence of these effects on the motion of fluid particles, focusing on cases where the frequencies associated with rotation and stratification (RaS), $N$ and $f$ respectively, are held at a fixed ratio $N/f=5$...
