We receive hundreds of photos from our viewers every day here at The Weather Network. But on Tuesday, one in particular caught our eye. Erin sent us this photo of a dust devil swirling near Balzac, Alberta -- north of Calgary.
What is a Dust Devil?
A dust devil is a strong, well-formed, and relatively long-lived whirlwind.
It forms when hot air near the surface rises quickly through a small pocket of cooler, low- pressure air above it.
If conditions are just right, the air may begin to rotate. Normally, this phenomenon occurs under sunny conditions during fair weather.
A dust devil is sometimes called a "dancing devil" or a "sun devil".
Now, it may LOOK like a tornado, but a dust devil rarely comes close to the intensity of a tornado. It is usually harmless.
