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.

TL;DR: In this paper, the Navier Stokes model on the sphere has been used to model the global circulation of the ocean, from the convective scale to the global scale, and a solution strategy has been proposed to deal with small-scale phenomena which are not in hydrostatic balance.

TL;DR: In this article, the authors describe carbon system formulation and simulation characteristics of two new global coupled carbon-climate Earth System Models (ESM), ESM2M and ESM 2G).

TL;DR: In this paper, the effect of irregular topography was studied using the finite-volume method and care was taken to ensure that the discrete forms have appropriate conservation properties, and two representations of topography, partial step and piecewise linear, were considered and compared with the staircase approach in some standard problems such as the topographic b effect and flow over a Gaussian bump.

TL;DR: This article presented results for simulated climate and climate change from a newly developed high-resolution global climate model [Geophysical Fluid Dynamics Laboratory Climate Model version 2.5 (GFDL CM2.5)] with an atmospheric resolution of approximately 50 km in the horizontal, with 32 vertical levels.
