effi cient method discerning climate-relevant sensitivities
2014/12/19
This paper explores the feasibility of an experimentation strategy for investigating sensitivities in fast components of atmospheric general circulation models.
Development of a parameterization of black carbon aging for use in general circulation models
parameterization of black carbon aging general circulation models
2014/12/16
A parameterization of black carbon (BC) aging in the atmosphere is developed for use in general circulation models (GCMs) that separately treat hydrophobic BC and hydrophilic BC modes but do not expli...
The Stability of Ocean Currents in Eddy-Resolving General Circulation Models
Ocean Currents Eddy-Resolving General Circulation Models
2009/2/23
The stability of currents generated in an oceanic eddy-resolving general circulation model EGCM (Holland, 1978) is investigated by solving the eigenvalue problem associated with the finite-difference ...
Parameter Sensitivity of Primitive Equation Ocean General Circulation Models
Primitive Equation Ocean General Circulation Models Parameter Sensitivity
2009/1/7
Experiments with a low resolution, primitive equation ocean general circulation model with idealized basin geometry and surface forcing have been carried out in order to identify the processes control...
Towards a better representation of the solar cycle in general circulation models
solar cycle general circulation models
2008/12/23
We introduce the improved Freie Universität Berlin (FUB) high-resolution radiation scheme FUBRad and compare it to the 4-band standard ECHAM5 SW radiation scheme of Fouquart and Bonnel (FB). Both...

A hierarchy of coarse-resolution World Ocean experiments were integrated with a view to determining the most appropriate representation of the global-scale water masses in ocean general circulation mo...
Thermohaline Oscillations Induced by Strong Steady Salinity Forcing of Ocean General Circulation Models
Thermohaline Oscillations Ocean General Circulation Models
2008/12/18
A series of numerical experiments is conducted with a three-dimensional ocean general circulation model and a two-dimensional counterpart both designed for efficient integration over diffusive (millen...
The Vertical Advection of Momentum in Bryan-Cox-Semtner Ocean General Circulation Models
Vertical Advection Bryan-Cox-Semtner
2008/12/12
This paper is concerned with the way that the Bryan-Cox-Semtner type ocean general circulation models represent the vertical advection of momentum, particularly at horizontal scales which are only sli...
A revised linear ozone photochemistry parameterization for use in transport and general circulation models: multi-annual simulations
linear ozone photochemistry parameterization general circulation models multi-annual imulations
2008/12/9
This article describes the validation of a linear parameterization of the ozone photochemistry for use in upper tropospheric and stratospheric studies. The present work extends a previously developed ...
The Role of Horizontal Boundaries in Parameter Sensitivity and Decadal-Scale Variability of Coarse-Resolution Ocean General Circulation Models
Horizontal Boundaries Parameter Sensitivity Coarse-Resolution Ocean General Circulation Models
2008/12/8
Coarse-resolution f-plane and β-plane frictional geostrophic models are used to study the response to restored surface buoyancies and fixed surface buoyancy fluxes. With restored surface buoyancies it...
Abyssal Channel Flow in Ocean General Circulation Models with Application to the Vema Channel
Abyssal Channel Flow Ocean General Circulation Models Vema Channel
2008/12/3
An idealized Cox model is shown to pass a flux given by g′H2/2f though a deep channel, single grid-box wide, consistent with analytical models. This flux can, however, be significantly increased or de...
