gigantic whirlwinds of sand which rise from the earth to the clouds: illustration from The Atmosphere, 1873, by Camille Flammarion. A whirlwind is a small-diameter columnar vortex of rapidly swirling air. While the term whirlwind can be applied to any atmospheric vortex, it is commonly restricted to atmospheric systems that are smaller than tornadoes but larger than eddies of microscale turbulence.
