Quantitatively mapping the Eady model onto a two-layer quasi-geostrophic model
Julie Meunier, Basile Gallet
The two-layer quasigeostrophic model (2LQG) and the Eady model are two idealized systems illustrating the baroclinic instability of atmospheric jets and ocean currents. The two set…

Statistics of near-inertial waves over a background flow via quantum and statistical mechanics
Alexandre Tlili, Basile Gallet
We revisit the interaction of an initially uniform near-inertial wave (NIW) field with a steady background flow, with the goal of predicting the subsequent organization of the wave…

Effective transport by 2D turbulence: Vortex-gas theory vs. scale-invariant inverse cascade
Julie Meunier, Basile Gallet
The scale-invariant inverse energy cascade is a hallmark of 2D turbulence, with its theoretical energy spectrum observed in both direct numerical simulations (DNS) and laboratory e…
