clover..ahh you saw it!..Yes that picture was taken near the end of great little asperitas(spelling has been revised due to a Latin expert’s perspective on grammar) event one morning in Mesa Az. Below is the event at a distance and some may remember this shot from Gallery or previous postings. To have such an event approach and roll overhead seemingly to be able to touch..leaves one in a place where words haven’t been originated to describe..yet.
A Good test for asperitas is..look at it upside down. Undulating waves should be easily discerned with pockets or depressions going up into the cloud base..Your photo when viewed upside down,,clearly demonstrates asperitas undulatus.
