Explanation

Willy-willy, most commonly known today as dust devils, is an upward spiralling, dust filled vortex of air that may vary in height from a few feet to over 1,000. They are usually several metres in diameter at the base, then narrowing for a short distance before expanding again. They mainly occur in desert and semi-arid areas, where the ground is dry and high surface temperatures produce strong updrafts.
