A classic example of asperitas, which can be likened to a more extreme form of undulatus. Asperitas differs from undulatus by the fact that its waves are more chaotic and disorderly, lacking any of the regularity and organisation typical of undulatus. This asperitas formation was spotted over Amesbury, Massachusetts, US.
