Katabatic Winds - Antarctica

Over Antarctica prominent cold katabatic winds are blowing for most of the year. This vid 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.

looks windy like mountain tops, on mountaineering and trekking videos, only this is right at sea level. what's a katabatic wind? I saw a big yellow cloud in the background.

This cold katabatic wind originates in a cooling of air at the top of the ice. Since the density of air increases with lower temperature, the air will flow downwards, warming adiabatically as it descends, but still remaining relatively cold.

Global warming is NOT a myth, nor a hoax and it is all our fault.

We're all going to die unless we listen to Al Gore.

Obey your master !
