Dust Devils

A dust devil is a rotating updraft that forms when hot air near the ground rises quickly through a small pocket of cooler, low-pressure air above it, picking up dust and debris as it spins. Formed most often over flat, barren terrain, dust devils are typically less than 3 ft (0.9 m) wide, reach maximum wind speeds of 45 mph (72 km/h), and dissipate in less than a minute. Though usually harmless, some are strong enough to pose a real danger. On what other planet have dust devils been observed? More...

Favourite weather phenomena of UFO "debunkers" (together with weather balloons, swamp gases and planet Venus + Jupiter).

I lived in northern Az. for 30 some yrs., just north of Prescott.I had friends that lived up on black mesa and one dayI went to visit. As i came over a rise on the main road there is a vista of the whole flat area before the rise of tehe mesa.Looking out i counted 15 dust devils going full tilt boogie over the flat. There might of been more but I had to keep my eyes on the road.......pretty cool.
