Exploring physics-dynamics coupling using moist shallow water equations
Nell Hartney, Thomas M. Bendall, Jemma Shipton
One of the key choices for numerical models of geophysical fluids is how parametrisations of physical processes interact with the numerical methods that handle the resolved flow, k…
A conservative, discontinuous Galerkin, tracer transport scheme using compatible finite elements
Timothy C. Andrews, Thomas M. Bendall
This paper outlines a conservative transport scheme for scalar tracers within a compatible finite element model for geophysical fluid equations. Instead of using the advective tran…
Exploring forms of the moist shallow water equations using a new compatible finite element discretisation
Nell Hartney, Thomas M. Bendall, Jemma Shipton
The moist shallow water equations offer a promising route for advancing understanding of the coupling of physical parametrisations and dynamics in numerical atmospheric models, an…
SWIFT: A Monotonic, Flux-Form Semi-Lagrangian Tracer Transport Scheme for Flow with Large Courant Numbers
Thomas M. Bendall, James Kent
Local conservation of mass and entropy are becoming increasingly desirable properties for modern numerical weather and climate models. This work presents a Flux-Form Semi-Lagrangia…
