Science Explains “Rough and Chaotic” Cloud Feature

Earth & Space Science News recently published an article about the asperitas cloud formation, the newest entry in the International Cloud Atlas. It includes commentary from Giles Harrison, an atmospheric physicist at the University of Reading, UK and Gavin Pretor-Pinney, founder of CAS, who together investigated the science behind asperitas. The team suggests that the new feature owes its appearance to oscillating streams of moving air contained with it and goes on to explain why asperitas forms.

It’s a very informative piece and you can read it in full here.
