A reduced model for surface wave-current interactions without spatial scale separation
Yohei Onuki, Yasushi Fujiwara
We propose a reduced asymptotic model for the mutual interaction between a weakly nonlinear surface gravity wave field and a slowly evolving incompressible current in a homogeneous…
Disentangling discrete and continuous spectra of tidally forced internal waves in shear flow
Yohei Onuki, Antoine Venaille
Generation of internal waves driven by barotropic tides over seafloor topography is a central issue in developing mixing and wave drag parameterizations for ocean circulation model…
Bulk-Edge Correspondence Recovered in Incompressible Geophysical Flows
Yohei Onuki, Antoine Venaille, Pierre Delplace
Bulk-edge correspondence is a cornerstone in topological physics, establishing a connection between the number of unidirectional edge modes in physical space and a Chern number, an…
Dynamical large deviations for an inhomogeneous wave kinetic theory: linear wave scattering by a random medium
Yohei Onuki, Jules Guioth, Freddy Bouchet
The wave kinetic equation predicts the averaged temporal evolution of a continuous spectral density of waves either randomly interacting or scattered by the fine structure of a med…
Breaking of internal waves parametrically excited by ageostrophic anticyclonic instability
Yohei Onuki, Sylvain Joubaud, Thierry Dauxois
A gradient-wind balanced flow with an elliptic streamline parametrically excites internal inertia-gravity waves through ageostrophic anticyclonic instability (AAI). This study nume…
From ray tracing to waves of topological origin in continuous media
Antoine Venaille, Yohei Onuki, Nicolas Perez +1
Inhomogeneous media commonly support a discrete number of wave modes that are trapped along interfaces defined by spatially varying parameters. When they are robust against continu…
Irreversible energy extraction from negative temperature two-dimensional turbulence
Yohei Onuki
The formation and transition of patterns of two-dimensional turbulent flows observed in various geophysical systems are commonly explained in terms of statistical mechanics. Differ…
Simulating turbulent mixing caused by local instability of internal gravity waves
Y. Onuki, S. Joubaud, T. Dauxois
With the aim of assessing internal wave-driven mixing in the ocean, we develop a new technique for direct numerical simulations of stratified turbulence. Since the spatial scale of…
