These aren't smooth and wavelike, like the undulatus cloud type we just looked at, but have a formation that is chaotic, like the stormy ocean we talked about earlier.

Altostratus undulatus cloud
The altostratus undulatus is a type of altostratus cloud with signature undulations within it. These undulations may be visible (usually as "wavy bases"), but frequently they are indiscernible to the naked eye. These formations will generally appear in the early stages of destabilizing return flows, especially over the southern plains of the United States, when the surface temperature is still relatively cool. The wavy strips of clouds are generally near an inversion surface.
