Comparative energetics analysis of CCM2 with different horizontal resolutions

Climate Dynamics, 1997
Comprehensive global energetics analysis is carried out for the NCAR CCM2 with different horizontal resolutions of R15, T42, T63, and T106 to assess the effect of various model truncations on the global energetics characteristics in climate models. Both the energy levels and energy transformations are examined over the zonal wave number domain during a

Description of the NCAR Community Climate Model (CCM2)

1993
This report presents the details of the governing equations, physical parameterizations, and numerical algorithms defining the version of the NCAR Community Climate Model designated CCM2 that represents a wholly new state-of-the-art atmospheric general circulation model, both functionally and in terms of its implementation and represents a major break ...

Diurnal Heating and Cloudiness in the NCAR Community Climate Model (CCM2)

Journal of Climate, 1994
In this paper, the authors assess the suitability of the heating fileds in the latest version of the National Center for Atmospheric Research (NCAR) Community Climate Model (CCM2) for modeling the thermal forcing of atmospheric tides. Accordingly, diurnal variations of the surface pressure, outgoing longwave radiation (OLR), cloudiness, and ...

Neuronal expression of the Ccm2 gene in a new mouse model of cerebral cavernous malformations

Mammalian Genome, 2006
Cerebral cavernous malformations are vascular defects of the central nervous system consisting of clusters of dilated vessels that are subject to frequent hemorrhaging. The genes mutated in three forms of autosomal dominant cerebral cavernous malformations have been cloned, but it remains unclear which cell type is ultimately responsible for the lesion.

A Novel MGC4607/CCM2 Gene Mutation Associated with Cerebral Spinal and Cutaneous Cavernous Angiomas

Journal of Molecular Neuroscience, 2015
Cerebral cavernous malformations (CCMs) are vascular abnormalities that may cause seizures, headaches, intracerebral hemorrhages, and focal neurological deficits; they can also be clinically silent and occur as a sporadic or an autosomal dominant condition.

Climate sensitivity of the NCAR Community Climate Model (CCM2) to horizontal resolution

Climate Dynamics, 1995
The dependence on horizontal resolution of the climate simulated by the National Center for Atmospheric Research Community Climate Model (CCM2) is explored. Simulations employing R15, T21, T31, T42, T63, and T106 horizontal spectral truncations are compared.

Cloud-Radiative Feedback as Produced by Different Parameterizations of Cloud Emissivity in CCM2

1996
Cloud-radiative feedback is negative in version 2 of the NCAR Community Climate Model (CCM2) in a surrogate climate change as employed in Cess et al. (1990). This negative cloud feedback is due to enhanced longwave emission caused by reduction of high clouds in a warmer climate (Zhang et al., 1994).

Middle atmosphere version of CCM2 (MACCM2): Annual cycle and interannual variability

Journal of Geophysical Research: Atmospheres, 1995
Aspects of the zonally averaged simulation produced by the middle atmosphere version of the latest generation of the National Center for Atmospheric Research (NCAR) Community Climate Model (CCM2) are discussed together with its dependence on horizontal resolution.
