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…

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…
