Journal ArticleDOI
An inherently mass‐conserving semi‐implicit semi‐Lagrangian discretization of the deep‐atmosphere global non‐hydrostatic equations
Nigel Wood,Andrew Staniforth,A. A. White,T. Allen,Michail Diamantakis,Markus Gross,Thomas Melvin,Chris Smith,Simon Vosper,M. Zerroukat,John Thuburn +10 more
TL;DR: In this paper, a mass-conserving semi-implicit (SI) semi-Lagrangian (SL) discretization of the 2D shallow-water equations and 2D vertical slice equations is extended to the 3D deep-atmosphere, non-hydrostatic global equations.
Journal ArticleDOI
A unified approach to energy conservation and potential vorticity dynamics for arbitrarily-structured C-grids
TL;DR: A numerical scheme applicable to arbitrarily-structured C-grids is presented for the nonlinear shallow-water equations, using the vector-invariant form of the momentum equation to guarantee that mass, velocity and potential vorticity evolve in a consistent and compatible manner.
Journal ArticleDOI
Numerical representation of geostrophic modes on arbitrarily structured C-grids
TL;DR: An explicit formula is given for constructing an appropriate discretization of the Coriolis terms and it is confirmed that the scheme does indeed give stationary geostrophic modes for the hexagonal-pentagonal and triangular geodesic C-grids on the sphere.
Journal ArticleDOI
Horizontal grids for global weather and climate prediction models: a review
Andrew Staniforth,John Thuburn +1 more
TL;DR: In this article, the authors present a survey and assessment of horizontal grids for modeling the atmosphere over the sphere, focusing on computational modes and grid imprinting, and the potential existence of computational modes on non-quadrilateral grids.
Journal ArticleDOI
The unified model, a fully-compressible, non-hydrostatic, deep atmosphere global circulation model, applied to hot Jupiters - ENDGame for a HD 209458b test case
Nathan J. Mayne,Isabelle Baraffe,David M. Acreman,Chris Smith,Matthew K. Browning,David S. Amundsen,Nigel Wood,John Thuburn,David Jackson +8 more
TL;DR: In this paper, the authors demonstrate the successful adaptation of the most sophisticated dynamical core, the component of the GCM which solves the equations of motion for the atmosphere, available within the EndGame (Even Newer Dynamics for General atmospheric modelling of the environment).
