RISSouthern Ocean Circulation and Eddy Compensation in CMIP5 Models
Publisher: American Meteorological Society
Abstract: hirteen state-of-the-art climate models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) are used to evaluate the response of the Antarctic Circumpolar Current (ACC) transport and Southern Ocean meridional ...
Impacts of Climate Change on the Subduction of Mode and Intermediate Water Masses in the Southern Ocean
Publisher: American Meteorological Society
Abstract: Changes in the temperature, salinity, and subduction of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW) between the 1950s and 2090s are diagnosed using the CSIRO Mark version 3.5 (Mk3.5) climate ...
Changes in the Subduction of Southern Ocean Water Masses at the End of the Twenty-First Century in Eight IPCC Models
Publisher: American Meteorological Society
Abstract: A multimodel comparison method is used to assess the sensitivity of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW) formation to climate change. For the Intergovernmental Panel on Climate Change A2 ...
Tracing Southwest Pacific Bottom Water Using Potential Vorticity and Helium-3
Publisher: American Meteorological Society
Abstract: his study uses potential vorticity and other tracers to identify the pathways of the densest form of Circumpolar Deep Water in the South Pacific, termed ?Southwest Pacific Bottom Water? (SPBW), along the 28.2 kg m?3 surface. ...
Role of the Seasonal Cycle in the Subduction Rates of Upper–Southern Ocean Waters
Publisher: American Meteorological Society
Abstract: kinematic approach is used to diagnose the subduction rates of upper?Southern Ocean waters across seasonally migrating density outcrops at the base of the mixed layer. From an Eulerian viewpoint, the term representing the ...
The Energetics of Southern Ocean Upwelling
Publisher: American Meteorological Society
Abstract: he ocean?s meridional overturning circulation is closed by the upwelling of dense, carbon-rich waters to the surface of the Southern Ocean. It has been proposed that upwelling in this region is driven by strong westerly ...
Water Mass Exchange in the Southern Ocean in Coupled Climate Models
Publisher: American Meteorological Society
Abstract: he authors estimate water mass transformation rates resulting from surface buoyancy fluxes and interior diapycnal fluxes in the region south of 30°S in the Estimating the Circulation and Climate of the Ocean (ECCO) model-based ...
Sensitivity of Antarctic Bottom Water to Changes in Surface Buoyancy Fluxes
Publisher: American Meteorological Society
Abstract: he influence of freshwater and heat flux changes on Antarctic Bottom Water (AABW) properties are investigated within a realistic bathymetry coupled ocean?ice sector model of the Atlantic Ocean. The model simulations are ...
The GFDL CM3 Coupled Climate Model: Characteristics of the Ocean and Sea Ice Simulations
Publisher: American Meteorological Society
Abstract: his paper documents time mean simulation characteristics from the ocean and sea ice components in a new coupled climate model developed at the NOAA Geophysical Fluid Dynamics Laboratory (GFDL). The GFDL Climate Model version ...
