Comments: A new category of cloud called the “undulatus asperatus.”
Well. That's just going to mess with the Federal Meteorological Handbook, let me tell you. There is just no provision for this sort of cloud in chapter 9.4.6, or in chapter 12.7.1(s) (significant cloud types). I mean, with altocumulus castellanus and cumulonimbus mammatus, there is at least a history, a tradition, if you will.
