- Whiteout
Today the term whiteout is often used to describe a blizzard or snowsquall when blowing snow has reduced visibility to a few metres. But this is not a true whiteout. True whiteouts occur mostly in the Arctic and the Antarctic when unbroken snow cover and a uniformly overcast sky combine to produce a solid white glow. People in whiteouts see no shadows or horizon and lose all sense of depth and orientation.
