Welcome to Dome Argus (Dome A)
Dome A is more than 1000km from the coast in all directions. It sits atop East Antarctica’s relatively broad, flat plateau, which creates some of the world’s strongest temperature-inversion conditions. The heat lost at the ice surface due to radiative cooling must be replaced by heat from the overlying near-surface atmosphere; therefore, the air at Dome A’s surface becomes extremely cold. Dome A’s very calm air conditions also play a role in making this area so cold, since the strongest inversions form in environments with the weakest winds. Because it is so much higher than Vostok (3448m), meteorologists expect that Dome A may soon break Vostok’s record for the lowest temperature ever recorded on Earth.
