Desert Wind and Windmills

Dust Devils
Born of the battle between the sun and sand, the dust devil is a rapidly rotating column of air that has wrapped itself around a rising thermal. The average dust devil is ten to fifty feet in diameter. The chief ingredients for a good dust devil are clear skies and a bright sun, along with a dry surface that can become very hot.
