Smaller than tornados, and usually harmless …
Dust devils form when a pocket of hot air near the earth surface rises quickly through cooler air above it, forming an updraft. The hot air rises because it is less dense than the cooler air. In the right conditions, the updraft begins to rotate.
The rising air stretches vertically, moving closer to the axis of rotation
which intensifies the spinning by conservation of angular momentum. The secondary flow of air causes more hot air to speed horizontally inward to the bottom of the forming vortex. As more hot air rushes toward the vortex to replace the rising air, the spinning intensifies.
[it’s a reinforcing feedback loop]
A fully-formed dust devil is a funnel-like chimney through which hot air moves upwards and in a circle. As the hot air rises, it cools, loses its buoyancy and eventually ceases to rise
seems they are found everywhere (even on mars).
“In Ireland, dust devils are known as "sí gaoithe" or "fairy wind" “

in australia they are commonly known by the name _____ _____
(From Yindjibarndi language, in the Pilbara)
