A storm chaser in Kananaskis, Canada filmed a stunning timelapse showcasing a unique weather formation which gives the illusion that clouds are rolling across the sky.

Tom Graham managed to capture the chinook arch in action as the clouds twist and turn across the skyline.

A chinook arch is formed by air rippling over mountains, the air is forced from a low elevation to a high one.

This footage was filmed on November 29.
