    On the Interactions Between Mean Flows and Inertial Gravity Waves in the WKB Approximation

    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–Boussinesq (EB) equations. Following G...

    Variational Stochastic Parameterisations and Their Applications to Primitive Equation Models

    We present a numerical investigation into the stochastic parameterisations of the Primitive Equations (PE) using the Stochastic Advection by Lie Transport (SALT) and Stochastic Forcing by Lie Transport (SFLT) ...

    Coupling of Waves to Sea Surface Currents Via Horizontal Density Gradients

    The mathematical models and numerical simulations reported here are motivated by satellite observations of horizontal gradients of sea surface temperature and salinity that are closely coordinated with the slo...
