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…
Splitting horizontal and vertical polynomial order in a compatible finite element discretisation for numerical weather prediction
Daniel Witt, Thomas Bendall, Jemma Shipton
The accurate and efficient representation of atmospheric dynamics remains a central challenge in numerical weather prediction. A particular difficulty arises from the strong anisot…
Fast-wave slow-wave spectral deferred correction methods applied to the compressible Euler equations
Alex Brown, Joscha Fregin, Thomas Bendall +3
This paper investigates the application of a fast-wave slow-wave spectral deferred correction time-stepping method (FWSW-SDC) to the compressible Euler equations. The resulting mod…
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…
