McMurdo Sound provides an important component in Antarctica's global effects upon climate. A key factor is the polar winds that can drive the sound's pack ice into the Ross Sea summer or winter. Frigid katabatic winds rake subsequently exposed water, causing sea ice to form.
The coast is warmer; on the coast Antarctic average temperatures are around −10 °C (14.0 °F) (in the warmest parts of Antarctica) and in the elevated inland they average about −55 °C (−67.0 °F) in Vostok. [13] [14] Monthly means at McMurdo Station range from −26 °C (−14.8 °F) in August to −3 °C (26.6 °F) in January. [15]
Air temperature and wind chill are no colder than −73 °C (−99 °F) And also must meet one or more of the following criteria: Visibility less than 300 metres (980 ft) Windspeed is greater than or equal to 48 knots (89 km/h; 55 mph) Air temperature and/or wind chill of −60 °C (−76 °F) or below; Weather Condition 1
Record high temperatures reportedly measured in Antarctica will take months to verify, the U.N. weather agency said Sunday. A spokesman for the World Meteorological Organization said the ...
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 ...
[8] [9] [10] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
While 2024 has been extremely warm, what kicked this week into new territory was a warmer-than-usual Antarctic winter, with temperatures 6 to 10 degrees Celsius (10.8 to 18 degrees Fahrenheit ...
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
