RISCharacteristics of Arctic Sea-Ice Thickness Variability in GCMs
Publisher: American Meteorological Society
Abstract: killful Arctic sea ice forecasts may be possible for lead times of months or even years owing to the persistence of thickness anomalies. In this study sea ice thickness variability is characterized in fully coupled GCMs ...
Atmospheric Circulation and Its Effect on Arctic Sea Ice in CCSM3 Simulations at Medium and High Resolution
Publisher: American Meteorological Society
Abstract: The simulation of Arctic sea ice and surface winds changes significantly when Community Climate System Model version 3 (CCSM3) resolution is increased from T42 (?2.8°) to T85 (?1.4°). At T42 resolution, Arctic sea ice is ...
The Effect of the Sea Ice Freshwater Flux on Southern Ocean Temperatures in CCSM3: Deep-Ocean Warming and Delayed Surface Warming
Publisher: American Meteorological Society
Abstract: his study explores the role of sea ice freshwater and salt fluxes in modulating twenty-first-century surface warming in the Southern Ocean via analysis of sensitivity experiments in the Community Climate System Model, ...
Linearity of the Climate System Response to Raising and Lowering West Antarctic and Coastal Antarctic Topography
Publisher: American Meteorological Society
Soil Thermal and Ecological Impacts of Rain on Snow Events in the Circumpolar Arctic
Publisher: American Meteorological Society
Abstract: Rain on snow (ROS) events are rare in most parts of the circumpolar Arctic, but have been shown to have great impact on soil surface temperatures and serve as triggers for avalanches in the midlatitudes, and they have been ...
Can North Atlantic Sea Ice Anomalies Account for Dansgaard–Oeschger Climate Signals?
Publisher: American Meteorological Society
Abstract: North Atlantic sea ice anomalies are thought to play an important role in the abrupt Dansgaard?Oeschger (D?O) cycles of the last glacial period. This model study investigates the impacts of changes in North Atlantic sea ...
The Climate Response to Stratospheric Sulfate Injections and Implications for Addressing Climate Emergencies
Publisher: American Meteorological Society
Abstract: tratospheric sulfate aerosol injection has been proposed to counteract anthropogenic greenhouse gas warming and prevent regional climate emergencies. Global warming is projected to be largest in the polar regions, where ...
A Heuristic Model of Dansgaard–Oeschger Cycles. Part I: Description, Results, and Sensitivity Studies
Publisher: American Meteorological Society
Abstract: simple model for studying the Dansgaard?Oeschger (D-O) cycles of the last glacial period is presented, based on the T. Dokken et al. hypothesis for D-O cycles. The model is a column model representing the Nordic seas and ...
Time-Varying Climate Sensitivity from Regional Feedbacks
Publisher: American Meteorological Society
Abstract: he sensitivity of global climate with respect to forcing is generally described in terms of the global climate feedback?the global radiative response per degree of global annual mean surface temperature change. While the ...
Mechanisms Forcing an Antarctic Dipole in Simulated Sea Ice and Surface Ocean Conditions
Publisher: American Meteorological Society
Abstract: The mechanisms forcing variability in Southern Ocean sea ice and sea surface temperature from 600 years of a control climate coupled model integration are discussed. As in the observations, the leading mode of simulated ...
