Southern Ocean
sea temperatures vary from about 10 degrees Celsius
to -2 degrees Celsius; cyclonic storms travel eastward around the
continent and frequently are intense because of the temperature
contrast between ice and open ocean; the ocean area from about
latitude 40 south to the Antarctic Circle has the strongest average
winds found anywhere on Earth; in winter the ocean freezes outward
to 65 degrees south latitude in the Pacific sector and 55 degrees
south latitude in the Atlantic sector, lowering surface temperatures
well below 0 degrees Celsius; at some coastal points intense
persistent drainage winds from the interior keep the shoreline
ice-free throughout the winter
