Antarctic Sea Ice: Physical Processes, Interactions and Variability
As sea ice formation plays a key role in driving Antarctic Bottom Water (AABW) production through brine rejection and the associated production of High Salinity freezing point Shelf Water 0tSSW), a possible link between interannual variability of the ice cover and changes in AABW production is expected. Analysis of satellite data indicates that the summer minimum extents (and area) in the Wedde...
متن کاملThe Role of Physical Processes in Determining the Interdecadal Variability of Central Arctic Sea Ice
The importance of the Arctic region for global climate change has recently been highlighted in the results from general circulation model simulations under increasing atmospheric CO2 scenarios. The warming that is predicted by these studies is most pronounced in the polar regions, indicating that it may be the first place in which the effects of global climate change will be detected. However, ...
متن کاملSnow on Antarctic Sea Ice
Snow on Antarctic sea ice plays a complex and highly variable role in air-sea-ice interaction processes and the Earth’s climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics: snow thickness and snow type and their geographical and seasonal variations; snow grain size, density, and salinity; frequency of occurrence of slush; thermal conduct...
متن کاملAntarctic Sea Ice History, Late Quaternary
Sea ice results from the freezing of surface sea water. In the Southern Ocean, sea ice surrounds the Antarctic continent and it today covers 20 × 10 km in winter and only 4 × 10 km in summer (Gloersen et al., 1992). This pronounced seasonal cycle strongly affects the climate of the Southern Hemisphere through its impacts on the energy and gas budget, on the atmospheric circulation, on the hydro...
متن کاملInterpretation of recent Antarctic sea ice variability
[1] Trends in the satellite-derived Antarctic sea ice concentrations (1979–2002) show pronounced increase (decrease) in the central Pacific sector (Bellingshausen/ western Weddell sector) by 4–10% per decade. Confidence levels for these regional trends exceed 95%. Positive polarities of the Antarctic Oscillation (AAO) lead to more (less) ice in the eastern Ross/Amundsen sector (Bellingshausen/n...
