Cool video Doug.
I don't really know what would cause such formations.
I can't even work up a good guess.
Very cool though.

Some special circumstance of pressure, temperature, and humidity, coupled with unknown forces?

This straight-up-cam time-lapse has some very fractal boundry tendril action going on. More Julia set than Mandelbrot in my judgement.

Hey Tomod!? Have you seen these clouds there is Oslo? Very rare stuff they are saying. .....

Nacrous clouds float 9 to 16 miles high, curling and uncurling hypnotically as they are stretched in and out by atmospheric gravity waves.

"The clouds were all over the sky today - from dawn til dusk," adds Morten Ross of Oslo, Norway. "Incredible!"

This is not my photo, but I was in the area paying attention when it was taken. This cloud form is called a lenticular cloud, and it's formed up on Mt. St. Helens volcano. Imaged captured from the USGS high-res volcano cam at Johnston Ridge.

Here's a photo of some rapidly forming cumulus clouds that my daughter took from our back yard a couple of years ago. I believe she had just turned 11.

Here's another lenticular cloud, Turtle, that formed over Mt. Fuji in Japan. This is not my photo either.

Cool find Reason, I bet it would look even better in person,

I propose a meteor might cause a round cloud.

"Our observations suggest that [meteors exploding] in Earth’s atmosphere could play a more important role in climate than previously recognized," the researchers write. ...

Yes I was leaning towards something like this, I was thinking some sudden heat source was rising into the upper cloud layer.

well off to find some clouds

I was sent this last night and I thought I would share this cool pic.




THIS IS A FIRE RAINBOW - THE RAREST OF ALL NATURALLY OCCURRING ATMOSPHERIC PHENOMENA.
THE PICTURE WAS CAPTURED THIS WEEK ON THE IDAHO/WASHINGTON BORDER. THE EVENT LASTED ABOUT 1 HOUR.
THE CLOUDS HAVE TO BE CIRRUS, AT LEAST 20K FEET IN THE AIR, WITH JUST THE RIGHT AMOUNT OF ICE CRYSTALS,
AND THE SUN HAS TO HIT THE CLOUDS AT PRECISELY 58 DEGREES.
