RISAntarctic Bottom Water Formation and Deep-Water Chlorofluorocarbon Distributions in a Global Ocean Climate Model
Publisher: American Meteorological Society
Abstract: The ocean distributions of chlorofluorocarbons (CFCs) have been measured extensively in order to determine the mechanisms, rates, and pathways associated with thermohaline deep-water formation. Model temperature, salinity, ...
Surface Ocean Fluxes and Water-Mass Transformation Rates in the Coupled NCAR Climate System Model
Publisher: American Meteorological Society
Abstract: The global distributions of the air?sea fluxes of heat and freshwater and water mass transformation rates from a control integration of the coupled National Center for Atmospheric Research (NCAR) Climate System Model (CSM) ...
Natural Variability in a Stable, 1000-Yr Global Coupled Climate–Carbon Cycle Simulation
Publisher: American Meteorological Society
Abstract: A new 3D global coupled carbon?climate model is presented in the framework of the Community Climate System Model (CSM-1.4). The biogeochemical module includes explicit land water?carbon coupling, dynamic carbon allocation ...
Mechanisms Governing Interannual Variability of Upper-Ocean Temperature in a Global Ocean Hindcast Simulation
Publisher: American Meteorological Society
Abstract: The interannual variability in upper-ocean (0?400 m) temperature and governing mechanisms for the period 1968?97 are quantified from a global ocean hindcast simulation driven by atmospheric reanalysis and satellite data ...
Marine Ecosystem Dynamics and Biogeochemical Cycling in the Community Earth System Model [CESM1(BGC)]: Comparison of the 1990s with the 2090s under the RCP4.5 and RCP8.5 Scenarios
Publisher: American Meteorological Society
Abstract: he authors compare Community Earth System Model results to marine observations for the 1990s and examine climate change impacts on biogeochemistry at the end of the twenty-first century under two future scenarios (Representative ...
Sensitivity to Surface Forcing and Boundary Layer Mixing in a Global Ocean Model: Annual-Mean Climatology
Publisher: American Meteorological Society
Abstract: The effects of more realistic bulk forcing boundary conditions, a more physical subgrid-scale vertical mixing parameterization, and more accurate bottom topography are investigated in a coarse-resolution, global oceanic ...
Twentieth-Century Oceanic Carbon Uptake and Storage in CESM1(BGC)
Publisher: American Meteorological Society
Abstract: cean carbon uptake and storage simulated by the Community Earth System Model, version 1?Biogeochemistry [CESM1(BGC)], is described and compared to observations. Fully coupled and ocean-ice configurations are examined; both ...
Response of the North Atlantic Thermohaline Circulation and Ventilation to Increasing Carbon Dioxide in CCSM3
Publisher: American Meteorological Society
Abstract: The response of the North Atlantic thermohaline circulation to idealized climate forcing of 1% per year compound increase in CO2 is examined in three configurations of the Community Climate System Model version 3 that ...
Ocean Chlorofluorocarbon and Heat Uptake during the Twentieth Century in the CCSM3
Publisher: American Meteorological Society
Abstract: An ensemble of nine simulations for the climate of the twentieth century has been run using the Community Climate System Model version 3 (CCSM3). Three of these runs also simulate the uptake of chlorofluorocarbon-11 (CFC-11) ...
The NCAR Climate System Model Global Ocean Component
Publisher: American Meteorological Society
Abstract: This paper describes the global ocean component of the NCAR Climate System Model. New parameterizations of the effects of mesoscale eddies and of the upper-ocean boundary layer are included. Numerical improvements include ...
