Hans the only thing I can say about ” conditions” is look for layers or duplicatus conditions. It seems to me..kind of like a Holmbroe Instability, where two layers of differing speed or maybe direction or maybe temperature, ,,interface so to speak, cause the Roll or wave action. I’ve wondered if Asperitas is like seeing a Holmbroe from underneath over large area? Another thought,,is Mammatus is air sinking, then Asperitas is like air rising?There ALWAYS seems cloudlets streaming upwards when above Asperitas can be seen. That just may be why I have observed perlucidus so often prior to an Asperitas event. Rising warm or hot air from the desert creates waves ??
Asperitas Lite
Looks to be tiny plankton, amoebas, biological in anycase Hans ,which of course produce the bubbles and alcohol …boozy shot!
I Wonder if they Dream in Color?
Recently I Caught This Progression. The 1st pic I took because it appeared the clouds had collided. The Cloud on the right is showing virga type trails streaming downward with hints of mammatus in the center of the pic, the point of collision. The 2nd shot was taken several minutes later, up to ten minutes later. Same cloud yet mammatus seems to weigh it down. There is still some virga visible on the opposite end.
Another tip or two while i was Thinking about, Canon offers choice for when shooting under cloudy conditions or when in bright sun light. I’ve found just because its cloudy out is NOT a good reason to switch over to ” cloudy” as far as white balance etc goes. Canon Cloudy translates to WARM , yellows etc. I have found to keep the color as I like them,,I don’t switch to ” cloudy” Especially when shooting irridescense . I don’t shoot thru filters when shooting irridescense either.
Sun flare is another problem when shooting for irridescense. Take a few seconds to see when the clouds start showing colors in relationship to how close they are to the sun. Remember, the eye/mind naturally goes to the brightest part of a pic.
Nice example of Holmboe(spl) Hans..I still think Holmboe should be designated as a cloud type rather than thought of as something a cloud is subjected to..but heck, one new cloud a life time is pretty special ( asperitas).
Ive mention often enough the speed that the weather has traveling across the Upper Sonoran Desert. The Picture here gives a clue. We’re talking several miles between the bottom of the pic to the top ( 5miles?) yet the cloud above sits looking motionless. Fascinating!
Samuel, I’ve read that even the experts aren’ t positive with whats going on with Mammatus..I’ve read that they proceed a storm then go outside and see them ahead of a storm. I see a lot of Mammatus in the Phoenix weather . Usually they are patchy, that is in a small area or as said at an end of a large system But I have photos showing a span of several miles of Mammatus. As far as relationship with tornadoes,,,,below is a shot of Mammatus I took from my backyard, while the local weather folks were sounding a Tornado Watch on the media. Thats as close as I want to be witnessing any relationship between Mammatus and Tornadoes. When I was in Kansas the same seemed to happen a lot. Tornado Watch was announced and Mammatus was in the sky. Both happen when a heavy duty system unleashes itself. But Mammatus doesn’t have to have a heavy duty cyclonic cell to happen .
Lots of movement!
Below is shot of strange. I think i took it at dusk and its really a small patch . The lighting makes it appear to be spikes. I really don’t know.
Captured a nice thin blanket of stratus gently undulating there Hans, But..the hole may be just a hole as in deteriorating rather than a fall streak hole.Where is the ” fall” part?
Dance stated off Vol II . I stumbled on the below shot taken almost a year ago, reminding me of a very social dance,,”The Electric Glide”. Seems like every Christmas party, Reunion, Reception, etc etc theres always the “Electric Glide”..well I suppose Clouds can too.
