According to the Met Office, “Asperitas is a distinctive but relatively rare cloud formation that takes the appearance of rippling waves.
“These wave-like structures form on the underside of the cloud to make it look like a rough sea surface when viewed from below.”
This Twitter user likened the grey sky as a “black hole.”

Exactly how the clouds are formed is unknown however, unstable atmospheric conditions are at times associated with the aftermath of a thunderstorm.
A London firefighter said on Twitter, “The cloud formation over London is incredible. I would love to know what type they are.
Antonia added, “They look like peaks of whipped meringues.”
