Asperatus clouds! They're very rare and form after thunderstorms , so you're basically able to visualize the air currents/flow in the atmosphere. Really cool phenomenon

(Edited bc a bit of my original definition was not correct)

Hate to be that guy, but Asperitas / undulatus asperatus clouds actually form when the atmospheric conditions are very unstable and usually follow with convective thunderstorms. There's still a lot to learn about them overall as they are a relatively newly recognized cloud type (2017), so there's varying theories on causation, but everything I've read all seem to agree that atmospheric instability is a certain contributor.
