McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999 The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross
Temperatures 70 degrees above normal in eastern Antarctica have baffled scientists, who say that the “unprecedented heat wave” has already changed the way experts think about the Antarctic ...
Weather Condition 3: Must meet all of the following criteria: Severe weather is possible within 24 to 48 hours; Visibility is greater than 300 metres (980 ft) Wind less than or equal to 45 knots (83 km/h; 52 mph) Air temperature and wind chill are above −60 °C (−76 °F) Weather Condition 2: Must meet all of the following criteria:
Antarctica sits on every line of longitude because the South Pole is on the continent. Theoretically, Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate.
The latest data shows high temperatures in portions of East Antarctica – where the most abnormal conditions are ongoing – that are typically between minus 58 and minus 76 degrees Fahrenheit ...
Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
The sea-ice runway site is still shown in flight tracking [12] [13] and airport information [1] [2] websites, leaving unresolved the question of its current official status. However, it has never been a fixed permanent location in any of its years of operation because of the annual melting of the ice in McMurdo Sound during the Antarctic summer.
Antarctica locks up 90 percent of the world's fresh water as ice and would raise sea levels by about 200 ft if it were all to melt. Antarctica hits record high temperature at balmy 17.5°C (63.5 ...
