On the kinetics of internal gravity waves beyond the hydrostatic regime
Vincent Labarre, Nicolas Lanchon, Pierre-Philippe Cortet +2
We present a new derivation of the kinetic equation for weak, non-hydrostatic internal gravity wave turbulence. The equation is equivalent to the one obtained by Caillol & Zeitlin…
Initial evolution of 3D turbulence en route to the Kolmogorov state: emergence and transformations of coherent structures, self-similarity and instabilities
Giorgio Krstulovic, Sergey Nazarenko
In this work, we study numerically the temporal evolution of an initially random large-scale velocity field under governed by the hyperviscous incompressible Navier-Stoke equations…
Internal gravity waves in stratified flows with and without vortical modes
Vincent Labarre, Pierre Augier, Giorgio Krstulovic +1
The comprehension of stratified flows is important for geophysical and astrophysical applications. The Weak Wave Turbulence theory aims to provide a statistical description of inte…
Hamiltonian derivation of the point vortex model from the two-dimensional nonlinear Schrödinger equation
Jonathan Skipp, Jason Laurie, Sergey Nazarenko
We present a rigorous derivation of the point vortex model starting from the two-dimensional nonlinear Schr{ö}dinger equation, from the Hamiltonian perspective, in the limit of wel…
Testing wave turbulence theory for Gross-Pitaevskii system
Ying Zhu, Boris Semisalov, Giorgio Krstulovic +1
We test the predictions of the theory of weak wave turbulence by performing numerical simulations of the Gross-Pitaevskii equation (GPE) and the associated wave-kinetic equation (W…
Equilibria and condensates in Rossby and drift wave turbulence
Jonathan Skipp, Sergey Nazarenko
We study the thermodynamic equilibrium spectra of the Charney- Hasegawa-Mima (CHM) equation in its weakly nonlinear limit. In this limit, the equation has three adiabatic invariant…
