RISInterannual Variability of Meridional Heat Transport in a Numerical Model of the Upper Equatorial Pacific ocean
Publisher: American Meteorological Society
Abstract: The interannual heat budget of the Pacific equatorial upwelling zone is studied using a primitive equation, a reduced gravity model of the upper Pacific equatorial ocean. The model is forced with monthly mean FSU winds ...
The Seasonal Cycle of Meridional Heat Transport in a Numerical Model of the Pacific Equatorial Upwelling Zone
Publisher: American Meteorological Society
Abstract: The seasonal heat transport mechanisms important in the Pacific equatorial upwelling zone are investigated using the primitive equation, reduced gravity model developed by Gent and Cane. Mechanisms of meridional heat ...
Why is the AMOC Monostable in Coupled General Circulation Models?
Publisher: American Meteorological Society
Abstract: his paper is concerned with the question: why do coupled general circulation models (CGCM) seem to be biased toward a monostable Atlantic meridional overturning circulation (AMOC)? In particular, the authors investigate ...
Diagnostic Model of the Three-Dimensional Circulation in the Upper Equatorial Pacific Ocean
Publisher: American Meteorological Society
Abstract: To investigate the processes that maintain the large-scale, annual-average thermal structure of the equatorial Pacific, the three-dimensional ocean circulation for a large area is determined from a diagnostic model applied ...
Tropical Pacific Variability in the NCAR Climate System Model
Publisher: American Meteorological Society
Abstract: A 300-yr simulation with the NCAR Climate System Model (CSM), version 1, captured only ?60% of the observed ENSO signal and exaggerated the interannual variability of SST in the western tropical Pacific. Here, a simulation ...
“El Niño Like” Hydroclimate Responses to Last Millennium Volcanic Eruptions
Publisher: American Meteorological Society
Abstract: he hydroclimate response to volcanic eruptions depends both on volcanically induced changes to the hydrologic cycle and on teleconnections with the El Niño?Southern Oscillation (ENSO), complicating the interpretation of ...
Sensitivity to Glacial Forcing in the CCSM4
Publisher: American Meteorological Society
Abstract: esults are presented from the Community Climate System Model, version 4 (CCSM4), simulation of the Last Glacial Maximum (LGM) from phase 5 of the Coupled Model Intercomparison Project (CMIP5) at the standard 1° resolution, ...
Intercomparison of Heat Fluxes in the South Atlantic. Part I: The Seasonal Cycle
Publisher: American Meteorological Society
Abstract: Intercomparison of the seasonal cycle for the fluxes of sensible and latent heat for four observation-based products [DaSilva, NCEP, Esbensen?Kushnir (EK), and the Southampton Oceanography Centre (SOC)] and the results for ...
Climate Sensitivity of Moderate- and Low-Resolution Versions of CCSM3 to Preindustrial Forcings
Publisher: American Meteorological Society
Abstract: Preindustrial (PI) simulations of the Community Climate System Model version 3 (CCSM3) at two resolutions, a moderate and a low resolution, are described and compared to the standard controls for present-day (PD) simulations. ...
Last Glacial Maximum and Holocene Climate in CCSM3
Publisher: American Meteorological Society
Abstract: The climate sensitivity of the Community Climate System Model version 3 (CCSM3) is studied for two past climate forcings, the Last Glacial Maximum (LGM) and the mid-Holocene. The LGM, approximately 21 000 yr ago, is a ...
