An Update on the Asperatus Cloud - Cloud Appreciation Society
WEBJul 20, 2011 · By studying the weather records and using a computer model to simulate the cloud, Graeme found evidence that asperatus is formed in the sort of conditions that produce mamma clouds (also known as mammatus), but when the winds up at the cloud level cause it to be sheared into wavelike forms known as undulatus. The conclusion was that there was a ...
