Nice shot Dave. Its a matter of timing. I see mostly asperitas undulatus in the Phoenix Arizona area. So ,yes, there is more of a structure to what I witness. Its a matter of timing like any wave activity. To me, Asperitas is upside down wave activity…like being under water and watching a wave break as it approaches the beach. It appears the wave goes Up and rolls along until it crests and comes apart. Pictures capturing what goes on above the asperitas show many rising columns of cloud.It is interesting to wonder when an asperitas events evolves to fractus, where the line is drawn.
Arizona Asperitas #782
