Original Note:
These unique wave clouds are called Asperitas (formerly undulatus asperitas). Their formation is not well understood, but one theory suggests they form when mammatus clouds descend into areas of wind shear causing the wavy pattern. They are commonly seen after thunderstorms. https://cloudatlas.wmo.int/en/clouds-supplementary-features-asperitas.html https://www.metoffice.gov.uk/weather/learn-about/weather/types-of-weather/clouds/other-clouds/asperitas
