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 2024 Antarctica heat wave refers to a prolonged and significant mid-winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above average. The heat wave was significant for occurring during ...
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 ...
The maximum recorded at Concordia on 17 March was -16.9 °C Pending the final data, in Vostok the value of -20.3 °C set the new monthly record but also exceeds the maximum of February (-22.2 °C ...
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 ...
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.
