The regional oceanic modeling system (ROMS): a split-explicit, free-surface, topography-following-coordinate oceanic model
TL;DR: In this paper, a split-explicit hydrodynamic kernel for a realistic oceanic model is proposed, which addresses multiple numerical issues associated with mode splitting, and is compatible with a variety of centered and upstream-biased high-order advection algorithms, and helps to mitigate computational cost of expensive physical parameterization of mixing processes and submodels.
Journal ArticleDOI
A finite-volume, incompressible Navier Stokes model for studies of the ocean on parallel computers
TL;DR: A preconditioner is used which, in the hydrostatic limit, is an exact integral of the Poisson operator and so leads to a single algorithm that seamlessly moves from nonhydrostatic to hydrostatic limits, competitive with the fastest ocean climate models in use today.

The Operational CMC–MRB Global Environmental Multiscale (GEM) Model. Part I: Design Considerations and Formulation
TL;DR: An integrated forecasting and data assimilation system has been and is continuing to be developed by the Meteorological Research Branch (MRB) in partnership with the Canadian Meteorological Centre (CMC) of Environment Canada.

A new dynamical core for the Met Office's global and regional modelling of the atmosphere
Trevor Davies,M. J. P. Cullen,A. J. Malcolm,M. H. Mawson,Andrew Staniforth,A. A. White,Nigel Wood +6 more
TL;DR: In this article, a computational scheme suitable for numerical weather prediction and climate modelling over a wide range of length scales is described, which is non-hydrostatic and fully compressible, and shallow atmosphere approximations are not made.

Interaction of a Cumulus Cloud Ensemble with the Large-Scale Environment, Part I
Akio Arakawa,Wayne H. Schubert +1 more
TL;DR: In this paper, large-scale modification of the environment by cumulus clouds is discussed in terms of entrainment, detraining, evaporation, and subsidence, and budget equations for mass, static energy, water vapor, and liquid water are considered.
Journal ArticleDOI
Available Potential Energy and the Maintenance of the General Circulation
TL;DR: The available potential energy of the atmosphere is defined as the difference between the total potential energy and the minimum total energy which could result from any adiabatic redistribution of mass as mentioned in this paper.

On the Changes in the Spectral Distribution of Kinetic Energy for Twodimensional, Nondivergent Flow
TL;DR: In this article, the authors considered the case where the fluid is defined over the total region of thc surface of a sphere and the nature of changes in time of the spectral distribution of kinetic energy is discussed on the basis of the two conservation requirements mentioned above.
Journal ArticleDOI
Energy and Numerical Weather Prediction
TL;DR: In this paper, an n-layer model with the appropriate energy invariants is developed, which is suitable for theoretical studies of the general circulation, and it is shown that if the equation of balance is used as a filtering approximation, all the terms in the vorticity equation which involve both the rotational and the divergent part of the wind field should be retained, while, if the geostrophic equation is used, all of these terms should be omitted.
