On the interactions between mean flows and inertial gravity waves in the WKB approximation
Darryl D. Holm, Ruiao Hu, Oliver D. Street
We derive a Wentzel-Kramers-Brillouin (WKB) closure of the generalised Lagrangian mean (GLM) theory by using a phase-averaged Hamilton variational principle for the Euler--Boussine…

Nonlinear dispersion in wave-current interactions
Darryl D. Holm, Ruiao Hu
Via a sequence of approximations of the Lagrangian in Hamilton's principle for dispersive nonlinear gravity waves we derive a hierarchy of Hamiltonian models for describing wave-cu…
