Tsunami Clouds Over Birmingham Explained [Video]

On Friday a series of strange clouds rolled across the Birmingham sky. Photos of the wave-like clouds spread across the internet as people wondered, what in the heck are those?

According to Life’s Little Mysteries, the clouds are pristine examples of “Kelvin-Helmholtz waves.”

Kelvin-Helmholtz waves form when a fast moving layer of fluid slides on top of a slower layer and drags its surface.

In this case, quicker clouds at higher altitudes are pulling at larger, slower clouds closer to the ground.
