Evaluation of ocean carbon cycle models with data-based metrics
(American Geophysical Union, 2004-04-02)
New radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment are used to assess a suite of 19 ocean carbon cycle models. We use the distributions and inventories of these tracers as quantitative ...
A Possible Feedback Mechanism Involving the Arctic Freshwater, the Arctic Sea Ice, and the North Atlantic Drift
(Science Press, 2004-03-15)
Model studies point to enhanced warming and to increased freshwater fluxes to high northern latitudes in response to global warming. In order to address possible feedbacks in the ice-ocean system in response to such ...
Evaluating Global Ocean Carbon Models: The Importance of Realistic Physics
(American Geophysical Union, 2004-09-15)
A suite of standard ocean hydrographic and circulation metrics are applied to the equilibrium physical solutions from 13 global carbon models participating in phase 2 of the Ocean Carbon-cycle Model Intercomparison Project ...
Last Glacial Maximum over China: Sensitivities of climate to paleovegetation and Tibetan ice sheet
(American Geophysical Union, 2003-02-06)
With the boundary conditions appropriate for the Last Glacial Maximum (LGM), including ice sheets, sea surface temperatures, sea-ice distribution, atmospheric CO2 concentration, the Earth’s orbital parameters, topography, ...
The Effect of Diapycnal Mixing on the Ventilation and CFC-11 Uptake in the Southern Ocean
(Science Press, 2004-03-04)
The Miami Isopycnic Coordinate Ocean Model (MICOM) is used to investigate the effect of diapycnal mixing on the oceanic uptake of CFC-11 and the ventilation of the surface waters in the Southern Ocean (south of 45°S). ...
The North Atlantic Oscillation and greenhouse-gas forcing
(American Geophysical Union, 2005-02-17)
The results of 12 coupled climate models participating in the Coupled Model Intercomparison Project (CMIP2) are compared together with observational data in order to investigate: 1) How the current generation of climate ...
Tracer-derived transit time of the waters in the eastern Nordic Seas
(Blackwell Munksgaard, 2005-08-25)
The spatial-temporal distribution of the anthropogenic radionuclide 137Cs originating from nuclear bomb testing and the Sellafield reprocessing plant in the Irish Sea is simulated using a global version of the Miami Isopycnic ...
The sensitivity of the present day Atlantic meriodinal overturning circulation to freshwater forcing
(American Geophysical Union, 2003-09-09)
Mounting evidence indicates that the Atlantic Meridional Overturning Circulation (AMOC) was strongly reduced during cold climate episodes in the past, possible due to freshwater influx from glacial melting. It is also ...
Two-phase, near-field modeling of purposefully released CO2 in the ocean
(American Geophysical Union, 2001-01-15)
A preliminary study on the relationship between Arctic Oscillation and daily SLP variance in the Northern hemisphere during wintertime
(Science Press, 2005-01-20)
In the present study, the authors investigated the relationship between the Arctic Oscillation (AO) and the high-frequency variability of daily sea level pressures in the Northern Hemisphere in winter (November through ...
