RISA Three-Dimensional Simulation of the Equatorial Quasi-biennial Oscillation
Publisher: American Meteorological Society
Abstract: A simulation of the equatorial quasi-biennial oscillation (QBO) has been obtained using a three-dimensional mechanistic model of the stratosphere. The model is a simplified form of the NCAR CCM (Community Climate Model) ...
Local Versus Nonlocal Boundary-Layer Diffusion in a Global Climate Model
Publisher: American Meteorological Society
Abstract: The results of a local and a nonlocal scheme for vertical diffusion in the atmospheric boundary layer are compared within the context of a global climate model. The global model is an updated version of the NCAR Community ...
Improvements to the NCAR CSM-1 for Transient Climate Simulations
Publisher: American Meteorological Society
Abstract: Improvements to the NCAR Climate System Model, CSM-1, primarily for transient climate forcing simulations, are discussed. The impact of the individual changes is assessed through atmosphere?land or ocean?ice experiments, ...
Climates of the Twentieth and Twenty-First Centuries Simulated by the NCAR Climate System Model
Publisher: American Meteorological Society
Abstract: The Climate System Model, a coupled global climate model without ?flux adjustments? recently developed at the National Center for Atmospheric Research, was used to simulate the twentieth-century climate using historical ...
The National Center for Atmospheric Research Community Climate Model: CCM3
Publisher: American Meteorological Society
Abstract: The latest version of the National Center for Atmospheric Research (NCAR) Community Climate Model (CCM3) is described. The changes in both physical and dynamical formulation from CCM2 to CCM3 are presented. The major ...
The GCM–Reality Intercomparison Project for SPARC (GRIPS): Scientific Issues and Initial Results
Publisher: American Meteorological Society
Abstract: To investigate the effects of the middle atmosphere on climate, the World Climate Research Programme is supporting the project "Stratospheric Processes and their Role in Climate" (SPARC). A central theme of SPARC, to examine ...
