This is a fantastic and rare shot of a wave-crashing cloud captured over Ingleton, North Yorkshire by a Weather & Radar user, do you know what they are?

Known as Kelvin-Helmholtz Wave Clouds, these types of cloud only last for a few minutes before dissipating without a trace.

Kelvin-Helmholtz clouds appear when the air is very unstable. They form when faster-moving, warm air flows over slower-moving, colder and denser air. If the speed at which the warm air travels over the colder air is fast enough, the undulating wave-like formation of the cloud appears.

These types of clouds can be spotted anywhere but vanish as quickly as they appear, so you need to be quick on the trigger!

If you spot waves in the clouds, or any natural spectacle, we would love to see! Submit images and videos using our uploader.
