From Glossary of Meteorology


A name given by Sir Douglas Mawson (1915) to violent, snow-carrying whirlwinds, from a few to over one hundred meters in diameter, that occur in otherwise calm air on the slopes of Adélie Land, Antarctica, at about the time of the equinoxes.

Over the sea, reportedly, they may lift brash 70–140 m into the air and form columns of water drops 1250 m high.

Mawson, Sir Douglas 1915. The Home of the Blizzard. 111–112.
