What is the strongest wind in Antarctica?
The air flow gets stronger, turning into fast-flowing winds called katabatic winds. These katabatic winds roar toward the coast of Antarctica. Fairly quiet conditions turn instantaneously, with katabatic winds reaching speeds of 15 to 20 meters per second (50 to 66 ft/sec)!
The Antarctic polar vortex is a stratospheric wind pattern. It blows strongly around the earth at about the latitude of the Antarctic coast. It is strongest in the colder times of the year and is driven by the temperature difference between the cold pole and the warmth of the lower latitudes.
Katabatic winds. “Over Antarctica prominent cold katabatic winds are blowing for most of the year. This video was taken near Hope Bay, it’s a force 8 wind with minus 20 degrees Celsius which results in an apparent temperature felt on the exposed skin (wind chill) of about minus 50 degrees Celsius.”. Katabatic Winds - Antarctica.
Sep 4, 2023 · But katabatic winds pouring off the ice sheet make the coastal zone of Antarctica much more blustery. Cape Denison along Commonwealth Bay boasts the highest average annual wind speed in the world: 44 mph (38 knots). Winds above 100 mph are not unusual in Antarctica.
Aug 16, 2019 · The Reason Antarctica Is Melting: Shifting Winds, Driven by Global Warming. A new study helps solve the puzzle of why the continent’s western glaciers are melting so fast.

January February March April May June July August September October November December. The average east-west (zonal) wind speed for 45°S to 75°S. This is near the peak of the polar jet maximum. A 45 m s -1 wind speed is equal to 100 mph. (Image is shown for 1 April–31 December on the 100-hPa surface.)
Nov 3, 2020 · The temperature gradient between the warm equator and the cold pole combine with the earth’s rotation to give us wind patterns like the ‘roaring forties’ and the ‘furious fifties’. Away from the surface in the winter polar stratosphere, the cold polar air drives the ‘polar vortex’. This spins air around the planet above Antarctica.
