Wind instruments recorded Antarctica's highest wind velocity at the coastal station Dumont d'Urville in July 1972 at 320 kilometres per hour (200 mph) (Australian Government Antarctic Division). Prevailing winds into McMurdo Sound shoot between mountain passes and other land formations, producing blizzards known locally as "Herbies".
This is the equivalent sea-level pressure; Tosontsengel is located at 1,300 metres (4,300 ft) above sea level. The highest adjusted-to-sea-level barometric pressure ever recorded (below 750 meters) was at Agata, Evenkiyskiy, Russia, elevation: 261 m (856.3 ft)) on 31 December 1968 of 1083.3 hectopascals (hPa) (31.99
Since the Last Glacial Period, temperature trends have suggested that the interplay from the Antarctic High and Southern Annular Mode has played a significant role in katabatic winds over the Patriot Hills Base Camp. [3]
Commonwealth Bay is an open bay about 48 km (30 mi) wide at the entrance between Point Alden and Cape Gray in Antarctica. It was discovered in 1912 by the Australasian Antarctic Expedition under Douglas Mawson , who established the main base of the expedition at Cape Denison at the head of the bay.
A ship in a force 12 ("hurricane-force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale (/ ˈ b oʊ f ər t / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
That’s cold, but Bismarck, North Dakota, has reached minus 20 degrees at least once a year in almost every year since 1875. Antarctica’s typical winter cold should be operating at a level ...
The fastest wind ever recorded was in the base Belgrano II at 351 km/h (218 mph). Antarctica has the world's lowest rainfall average (zero at the Geographic South Pole) and thus is the world's driest continent. Despite its low rainfall average, Antarctica has approximately 70% of the world's fresh water (as well as 90% of the world's ice).
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt—around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice—the seas would rise by over 60 m (200 ft). [22]
