McMurdo Sound experiences katabatic winds from the Antarctic polar plateau. McMurdo Sound freezes over with sea ice about 3 metres (9.8 ft) thick during the winter. During the austral summer when the pack ice breaks up, wind and currents may push the ice northward into the Ross Sea, stirring up cold bottom currents that spill into the ocean basins.
According to the World Meteorological Organization in Geneva, the new record high temperature on continental Antarctica is a downright pleasant 63.5 degrees Fahrenheit (17.5 degrees Celsius). The ...
