Why Antarctica Is the Coldest Continent
Why Antarctica Is the Coldest Continent
- Polar Position: Centered on South Pole – minimal solar angle.
- High Elevation: Avg 2,000 m (6,560 ft) – thins atmosphere, enhances radiative cooling.
- Polar Night: Months of darkness in winter – no solar input.
- Katabatic Winds: Cold, dense air drains from interior to coast, accelerating cooling.
- Ice Sheet Albedo: 2+ km thick ice reflects ~80‑90% of incoming radiation.
- Antarctic Circumpolar Current: Isolates continent from warmer ocean heat transport.
Combined, these create Earth’s ultimate cold trap.
