Dust devils form when hot air at the surface begins to rise rapidly with much cooler air above it and higher up into the atmosphere. The hot air then stretches and causes a spinning motion much like a tornado. They are short-lived because cold air eventually gets pulled in and dissipates the dust devil.

Do dust devils have rotate?

THE direction of rotation of 'dust devils' has been noted in Lower Egypt and Iraq during the past four years, and the reports received in this office indicate that in about 50 per cent of cases the direction of rotation is clockwise, and in the other 50 per cent anticlockwise.

Why can dust devils rotate in any direction?

Unlike much larger storms such as hurricanes and tornadoes, dust devils may rotate either cyclonically or anticyclonically. Their size is such that the earth's rotation appears to have no effect on their direction of spin, and each direction occurs with approximately equal frequency.
