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 ...
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 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 ...
Effects of solar irradiance forcing on the ocean circulation and sea-ice in the North Atlantic in an isopycnic coordinate ocean general circulation model
The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ...
Simulating transport of non-Chernobyl 137Cs and 90Sr in the North Atlantic–Arctic region
The spatial and temporal distributions of the anthropogenic radionuclides 137Cs and 90Sr, originating from nuclear bomb testing and the Sellafield reprocessing plants in the Irish Sea, are simulated using a global version ...
A brief history of climate – the northern seas from the Last Glacial Maximum to global warming
The understanding of climate and climate change is fundamentally concerned with two things: a well-defined and sufficiently complete climate record to be explained, for example of observed temperature, and a relevant ...
