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]
The AMRC is one of the primary archives of meteorological data from Antarctica and its surrounding geographic areas. [1] The Antarctic Meteorological Forecast Center (AMFC) at UW-Madison was devised during the same time as the founding of the AMRC as a provider of weather forecasts for research vessels operating in the vicinity of Antarctica.
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 has the world's most southerly harbor, this is important for bringing supplies to McMurdo and in support of projects in the Antarctic, but weather conditions necessitate an icebreaker. An example of a resupply ship is the MV American Tern , which was chartered from 2001-2010.
The mean annual temperature is −18 °C (0 °F). Temperatures may reach as high as 8 °C (46 °F) in summer and −50 °C (−58 °F) in winter. The average wind speed is 12 knots (22 km/h; 14 mph), but winds have exceeded 100 knots (190 km/h; 120 mph). [8] McMurdo Sound is a historic area.
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 ...
