The puzzling Venusian polar atmospheric structure reproduced by a general circulation model [PDF]
Nature Communications, 2016 Unlike some planets, the Venusian polar vortex is warmer than the mid-latitudes at cloud-top level, but the mechanism behind this is unknown. Here, the authors use a general circulation model and suggest the cold collar and warm polar regions are due to ...

A Dynamic Mixed Model for General Circulation Models
Meteorologische Zeitschrift, 2023 An extension of the dynamic Smgarorinsky model (DSM) is presented. In the so-called dynamic mixed model (DMM), the Leonard stress (i.e., the resolved part of the Reynolds stress) is no longer parameterized in the test filter range by the Smagorinsky ...

Optimisation of a parallel ocean general circulation model [PDF]
Annales Geophysicae, 1997 This paper presents the development of a general-purpose parallel ocean circulation model, for use on a wide range of computer platforms, from traditional scalar machines to workstation clusters and massively parallel processors.

Waves in a Venus general circulation model [PDF]
Geophysical Research Letters, 2014 AbstractWaves in the Venus atmosphere are numerically investigated by extending a work of Sugimoto et al. (2014). Fast superrotating zonal flow of 120 m s−1 at the equator is reproduced and maintained by solar heating for more than 10 Earth years. The meridional distribution of the obtained fast zonal flow is quite consistent with observations at the ...

Passive tracers in a general circulation model of the Southern Ocean [PDF]
Annales Geophysicae, 1999 Passive tracers are used in an off-line version of the United Kingdom Fine Resolution Antarctic Model (FRAM) to highlight features of the circulation and provide information on the inter-ocean exchange of water masses.

Global Modeling of Internal Tides Within an Eddying Ocean General Circulation Model [PDF]
Oceanography, 2012 Ocean tides, and the atmospherically forced oceanic general circulation and its associated mesoscale eddy field, have long been run separately in high-resolution global models. They are now being simulated concurrently in a high-resolution version of the

Global Coupled General Circulation Models [PDF]
Bulletin of the American Meteorological Society, 1995 Major conclusions and recommendations regarding the status of global coupled general circulation models are presented here from a workshop convened by the World Climate Research Programme Steering Group on Global Coupled Modelling that was held from 10 to 12 October 1994 at the Scripps Institution of Oceanography, La Jolla, California.

Predicting the Impact of Climate Change on Temperature in Sanandaj City [PDF]
محیط زیست و مهندسی آب, 2021 The GCM models are widely used to assess the effects of global climate change, but they are not accurate enough to assess climate change locally and regionally.

Are general circulation models obsolete?
Proceedings of the National Academy of Sciences, 2022 Traditional general circulation models, or GCMs—that is, three-dimensional dynamical models with unresolved terms represented in equations with tunable parameters—have been a mainstay of climate research for several decades, and some of the pioneering studies have recently been recognized by a Nobel prize in Physics.
