RISAntarctic Sea Ice Extent Variability and Its Global Connectivity
Publisher: American Meteorological Society
Abstract: This study statistically evaluates the relationship between Antarctic sea ice extent and global climate variability. Temporal cross correlations between detrended Antarctic sea ice edge (SIE) anomaly and various climate ...
A Convective Model for the Weddell Polynya
Publisher: American Meteorological Society
Abstract: Mechanisms are considered which may induct the large (over 105 km2) area of open water, or polynya, which frequently occurs within the Weddell Sea winter sea-ice. We propose that when surface cooling and ice formation ...
Origin and Attenuation of Mesoscale Structure in Circumpolar Deep Water Intrusions to an Antarctic Shelf
Publisher: American Meteorological Society
Abstract: AbstractCross-isobath transport of Upper Circumpolar Deep Water (UCDW) provides a major source of heat to the Antarctic continental shelves. Adaptive sampling with a Slocum glider revealed that the UCDW regularly intrudes ...
The Impact of Sea Ice Concentration Accuracies on Climate Model Simulations with the GISS GCM
Publisher: American Meteorological Society
Abstract: The Goddard Institute for Space Studies global climate model (GISS GCM) is used to examine the sensitivity of the simulated climate to sea ice concentration specifications in the type of simulation done in the Atmospheric ...
Extreme Anomalous Atmospheric Circulation in the West Antarctic Peninsula Region in Austral Spring and Summer 2001/02, and Its Profound Impact on Sea Ice and Biota
Publisher: American Meteorological Society
Abstract: Exceptional sea ice conditions occurred in the West Antarctic Peninsula (WAP) region from September 2001 to February 2002, resulting from a strongly positive atmospheric pressure anomaly in the South Atlantic coupled with ...
