A dust devil becomes a dance partner during an Australian music festival last week |
A dust devil blew through, giving people a literal whirlwind moment as the music played.
Dust devils form when the sun heats an area of ground more intensely than surrounding areas. Maybe there's darker ground or a lack of foliage that makes the patch of ground heat more than areas nearby.
The hot air rises, through cooler air above, so basically you get a column of warm, rising air. The cool air that has been pushed away by the warm column circulates vertically, up and down. Then a gust of wind knocks that circulating air sideways, so now it circulates horizontally. So it forms into a column of circulating air - a dust devil.
The Australian festival dust devil looks fairly intense at first in the video you see below, so I wonder if it was a little dangerous to get into it.
But nobody got hurt and a good time was had by all.
