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 ...

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.

Status and Improvements of Coupled General Circulation Models

Science, 2000
Coupled general circulation models (CGCMs) integrate our knowledge about atmospheric and oceanic circulation. Different versions of CGCMs are used to provide a better understanding of natural climate variability on interannual and decadal time scales, for extended weather forecasting, and for making seasonal climate scenario projections. They also help

NAO–ocean circulation interactions in a coupled general circulation model

Climate Dynamics, 2008
The interplay between the North Atlantic Oscillation (NAO) and the large scale ocean circulation is inspected in a twentieth century simulation conducted with a state-of-the-art coupled general circulation model. Significant lead–lag covariance between oceanic and tropospheric variables suggests that the system supports a damped oscillatory mode ...

Comparison of general circulation models

AIP Conference Proceedings, 1992
Radiative forcing of Earth’s climate due to increases in greenhouse gases is compared in a number of Geneal Circulation Models. Feedback effects due to water vapor and clouds are discussed. (AIP)

Atmospheric General Circulation Modeling

2012
This entry provides a brief introduction to the computer models of the atmosphere used for climate studies. The concepts of atmospheric forcing and response are developed and used to highlight the importance of clouds and aerosols to the climate system and the many uncertainties associated with their representation.

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 ...

Modeling of the radiative process in an atmospheric general circulation model

Applied Optics, 2000
A new radiation scheme has been developed for dynamic general-circulation modeling. An automatic determination of k-distribution parameters and a treatment of solar-terrestrial radiation interacting with gaseous and particulate matter are incorporated into the scheme by a technique that combines discrete ordinate and matrix operator methods.
