A notable storm system in an area that Santiago described as formerly being desolate without any vegetation. Over the past few decades, Chinese forest rangers planted trees and gradually nurtured the environment back to life. Today, there are endless stretches of lush forest farms, as seen here near the Saibangba Forest Farm, Weichang County, Chengde City, Hebei Province, China.

Asperitas is a relatively rare formation that seems to form in the vicinity of Cumulonimbus storm systems. 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 classic example of asperitas was spotted over Northern California, US.
