Twitter User Captures Dust Devil Dancing on Portland

Dust Devil

A quick thinking Twitter user has managed to capture a picture of a quick moving Dust Devil on Portland.

Amy Frost was a passenger in a car when she noticed what she described as a Dust Devil kicking up the sand on Chesil Beach car park yesterday (Monday 23rd June).

The narrow column of wind swept up sand and dust into small-scale rotations on the ground amongst the parked cars.

No need to worry though, dust devils are nothing to do with severe weather systems like tornadoes and twisters, so Dorset is safe from an extreme weather apocalypse - for now anyway.

Experts say the swirling air is made visible by dust or dirt on the ground which means that they are more common in areas with loose dirt or sand:

"As the ground heats up in hot areas the rising air can create a vortex that picks up the loose soils and whirls them into the air.

This convection will lead to the formation of a slow moving and usually harmless swirls of moving air."
