Record-Breaking Low Temperatures The extreme climate of the continent is not just theoretical; it is measured and documented. The thermometer plunged to a staggering -89.
Understanding the Polar Vortex Behind Antarctica's Reign as the Coldest Continent
This leads to the development of the polar vortex, a persistent large-scale cyclone located in the stratosphere. In comparison, the coldest temperatures recorded in the Arctic, while brutally cold, typically remain in the range of -50°C (-58°F) to -60°C (-76°F), because the heat stored in the ocean provides a moderating influence that is absent on the Antarctic landmass.
Water has a high heat capacity, meaning it releases stored warmth slowly, preventing the air above it from reaching the extremes possible on land. During the Antarctic winter, the sun disappears below the horizon for months, cutting off the primary source of heat.
Understanding the Polar Vortex in Antarctica
Comparing Antarctica to the Arctic To fully appreciate why Antarctica is the coldest continent, a direct comparison with the Arctic is essential. The Antarctic ice sheet has an average height of about 2,500 meters (8,200 feet) above sea level.
