A simple hydrologically based model of land surface water and energy fluxes for general circulation models

, 1994
A generalization of the single soil layer variable infiltration capacity (VIC) land surface hydrological model previously implemented in the Geophysical Fluid Dynamics Laboratory (GFDL) general circulation model (GCM) is described.

Anomaly General Circulation Models

Journal of the Atmospheric Sciences, 1988
Abstract Anomally models based on a spectral general circulation model (GCM) are formulated and applied to study of low-frequency atmospheric variability in the extratropics, and long-range forecasting research. A steady linear version of the anomaly model is treated by a matrix method.

Modeling the Oceanic General Circulation

Annual Review of Fluid Mechanics, 1996
This article reviews the history, formulation, and solution behavior of relatively comprehensive numerical models for the oceanic general circulation under equilibrium surface wind stress and buoyancy flux forcing. The issues of model formulation are both the customary and alternative dynamical approximations of the fundamental fluid dynamics, the ...

Hospitable archean climates simulated by a general circulation model.

Astrobiology, 2013
Evidence from ancient sediments indicates that liquid water and primitive life were present during the Archean despite the faint young Sun. To date, studies of Archean climate typically utilize simplified one-dimensional models that ignore clouds and ice.

A mean motion model of the general circulation

Quarterly Journal of the Royal Meteorological Society, 1965
AbstractEquations are constructed to represent quasi‐stationary mean flow of momentum and heat on a spherical earth, averaged over a long period of time such as a year and over latitude circles. The crucial shearing Reynolds stress associated with meridional transfer of zonal velocity is assumed to depend linearly on a product of the earth's angular ...

Weather Regimes in a General Circulation Model

Journal of the Atmospheric Sciences, 1990
Abstract Perpetual January and July simulations each 1200 days long of the NCAR Community Climate Model (CCM0B) are investigated for the existence of large scale, midlatitude weather regimes. Four realizations of the midlatitude circulation were considered: Northern Hemisphere (NH) winter, Northern Hemisphere summer, Southern Hemisphere (SH) winter ...

Decadal variations in a Venus general circulation model

Icarus, 2011
The Community Atmosphere Model (CAM), a 3-dimensional Earth-based climate model, has been modified to simulate the dynamics of the Venus atmosphere. The most current finite volume version of CAM is used with Earth-related processes removed, parameters appropriate for Venus introduced, and some basic physics approximations adopted.
