As some of you may know, I go to The Ohio State University In Columbus, OH. Walking on campus yesterday afternoon I noticed these clouds. If you look closely you can see a wavy like base to the close. So in meteorology we call these clouds altostratus undulatus clouds or asperitas clouds.
How do they form you may ask?
“One theory does suggest that they are formed when mammatus clouds descend into areas of the sky where wind direction changes with height causing the wave-like movement.”
Now hopefully you have a better understanding of these clouds.
