Yes Ruth nothing but a grey brown haze for a week or so now, can barely make out clouds through the haze.Really disgusting,frustrating, and unhealthy. Satellite shots show what a complete catastrophe the West has become. Since there is such a thing it should be called a pirrostratus. Anyway..in hopes for at least some clearer sky..

Dave..I can only suggest that there exists Aperitas Laconosus. I’ve witnessed such a development on many an occasion, usually at the end of an Asperitas event. Again. its a timing issue. What actually is the physical cause, the physics responsible for the development we call asperitas? My rough understanding is ..a layer of stratus is acted upon by winds above the stratus. The speed of the winds and the direction in relationship to the speed and direction of the stratus I don’t recall exactly. Undulatus is caused by winds 90 degrees (?) opposed to the direction of the stratus. Since there is asperitas undulatus there is suggested ,wind speed has much to do with asperitas. Another thought is volume..how much space a blast of wind fills.
The lacunosus phenomena is attributed to different temperature layers of atmosphere descending and rising into each other. Cold air condenses the moisture out of the atmosphere and warm air absorbs the moisture back into atmosphere. So the cloud pattern you see is the cold air descending and the holes are the warm air rising..The problem is the holes in asperitas have visible clouds but they are in column shape and very ragged, due to wind. What im suggesting , and it is only my opinion, is that the lacunosus we see near the end of an asperitas event may be in optics only, similar to an lacunosus we see at cirrus or altcum heights,but the physics could be different Again, Aperitas does mean mixed up, indicating a multi-directional stirring of the atmosphere. So the thought that asperitas lacunosus signals a equilibrium approaching, a calming down of the asperitus atmosphere seems possible. The one thing bears mentioning is that the lacunosus I’ve photographed near the end of an asperitas event is usually almost ,f not directly, overhead. Seeing the wavy nature of asperitas is difficult when overhead and easier when seen at an angle or farther away.
So thats my 2 cents based on what little I understand about a complicated physical event that happens to clouds. I will say that I’ve photographed Asperitas Radius. Posted those pics a long while ago. Asperitas Translucidus might be applied to #773, #778 and #780 above.Point is, there can be many types of Asperitas and like a lot of clouds there are phases of development and decomposure that take the phenomena thru various varieties. There is much study on inter-actions of various layers of differing temperatured liquids and gases. Asperitas seems to me a challenge to those in that field of study.
anyway here is a “asperitas lacunosus” shot that was close by.

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.

Great show you had in Missouri there Dave! ..
In very general terms..I reduce my photos from full size down to about 4″ X 7″ (postcard) size or 450 kb in size to get accepted to post here. The exception is the vertical shots which CAS allows to be larger. Anyway you will figure it. Yes you end up with an original and then a CAS smaller version of all your good stuff.
