Deterministic and Stochastic Geometric Mechanics for Hall MHD
Darryl D. Holm, Ruiao Hu, Oliver D. Street
We derive new models of stochastic Hall magnetohydrodynamics (MHD) by using a symmetry-reduced stochastic Euler-Poincaré variational principle. The new stochastic Hall MHD theory h…

Geometric theory of perturbation dynamics around non-equilibrium fluid flows
Darryl D. Holm, Ruiao Hu, Oliver D. Street
The present work investigates the evolution of linear perturbations of time-dependent ideal fluid flows with advected quantities, expressed in terms of the second order variations…

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…
