Awesome time-lapse video: Undulatus Asperatus clouds

Unique clouds like you’ve never seen them before! I just thought I’d pass these along due to the unique “catch the wave” appearance of these. Time lapse video follows.

undulatus-asperatusThis video was taken with an iPhone 6 by Dr. Alan Walters from the University Hospital window in Augusta, GA. Walters, an anesthesiologist at the hospital, said he taped his phone to the window while he put an epidural In a patient.

“I guess I was finally in the right place at the right time,”

Walters said.

Very cool. Thanks for sharing.

Best reason I’ve seen to look at an Iphone 6. That was something!

How long does it take to put an epidural in a patient !!?

$800-$,1200. time is irrelevant.

Same here, thanks for sharing the video.

Great pics, we see this in our valley at certain times that the weather pattern and airflow are at a 90 degree angle to our N-S valley. On both the east and the west sides there are plateaus at ~3600′, the lake is at ~1200″ . As the moist air moves over us they create this and we have loved watching it although it sure doesn’t happen this fast but we will try and do his video ourselves it is really cool !!! Tanks Doc, ( I hope the op went well).

Forgot, we call them “Roll Clouds” as the video shows. A few years ago we had a ( very unusual in our Valley) “Wall Cloud” formation an indication of a potential tornado. It was spinning and showed 5 distinct “walls” around it’s center as it rotated and eventually released it’s energy North of us with a violent hail storm.

Hail tonight here in S London, whilst getting off the train home.
Nothing like those clouds, though . . . .

Ha!!! Just H2O.
Raining copius amounts of guano in the USA capitol these days.

It reminds me a bit of watching waves from underwater, such as in this beautiful video.

I had the same thought; the clouds rolling by look like water waves from below the surface.

Such is the reactionary line separating a medium of liquid from a medium of gas or oil and water

The video is, indeed, beautiful, but the “music” was dreadful–noisy, inconsequential, totally lacking in beauty, sweep, or dignity, and utterly unsuited to the subject matter. I had to turn off the sound to endure watching the video.

Definition of unique :Being the only one of its kind; unlike anything else:
Now I suppose that each cloud is unique in the same way that every snowflake is unique, but it is a word that gets a bit over-used.

Enigmatic is also applicable. At least until we fully comprehend cloud formation.

At least ‘very unique’ wasn’t deployed. That’s the one that makes me want to reach for .50 BMG

Yes MaxP…I agree with that! Something is either unique or it isn’t; there are no degrees of uniqueness.

Certainly a more entertaining aspect of climate forcing than CO2!

Is the video congruent in any manner with ELF waves?

March 31, 2015 3:37 pm

That would have so freaked me out.
Glad to see it in a small screen.

As it is elsewhere, Lord Monckton. People in the US heartland are beginning to wake up and question the urgency of the political movement borne of the CAGW meme. And the hiatus continues.

A nice illustration of gravity waves in the atmosphere. They are really very common, but most people don’t notice them because they are hard to spot from the ground, partly from the large size and partly from the relatively slow motion without time-lapse video. Satellite imagery shows them all over the place and satellite animations are effectively time-lapse videos.

This is a very good illustration of how our planets electromagnetic fields interact with our atmosphere. Just like an ocean, there are eddies and under currents seemingly unaffected by each other but still working in perfect harmony.
Awesome to see such a clear example of our atmosphere at work.

Geez, I just assumed that these were weaponized chemtrails…

I have some difficulty with establishing undulatus without a height distinction as a genus of clouds. For one thing, I have seen altostratus undulatus do stuff somewhat like this, and also I have seen this in photos in a few library books and a couple school posters – before 1980 even. So, I think this cloud form is what I would say is stratocumulus undulatus.

That one was small compared to the ones I saw on an overcast day back in May of 2009, west of O’Hare Airport in the Chicago suburbs. Heading eastward towards on I-90 and approaching Schaumburg, I saw not one or two like this one was, but several parallel ones, extending as far to the east as I could see, and about half a kilometer wide each (I clocked their spacing on my odometer, while southbound). They were all laid out in front of me and I had plenty of time to notice them and try to observe them. There were at least a few, 3 or 4 or more, as well as to the south. When I got to IL-53/I-290 and headed south, the parallels continued, for mile after mile, following it as I-290 swung south 8 km east. I got down onto the Kingery freeway – 2 miles east of IL-53 and went south there, too. They finally faded into blue sky little by little down around Burr Ridge in the south suburbs. I measured later on Google Earth, and the pattern extended about 18 km on the path I was on, plus the extra ones to the north, at least another 3 km. That would make about 40-45 of the barrel-vaulted asperatus.
I had never HEARD of asperatus until that day. I had to look them up on the internet and find out what the heck they were.
I got some photos looking eastward on I-90 after pulling over and some while driving south. They were all barrel-vaulted and LONG – no shorter than 15-20 kilometers long, E-W, which was the direction of their alignment. I saw them originally while in Hoffman Estates, at about Barrington Road, and they extended back over my head to the west for at least 3 or 4 km. And they were seemingly stationary, not like the rolling ones in this video (yes, it was time-lapse and mine was not).
It is not often that clouds organize in any way, and people mostly think that they can’t at all. But they DO. And this was over a large area – about 20 km x 21 km or 420 sq km.

Beautiful, it’s like looking up after falling off the surfboard

This is a bit late, but we had weird clouds over Kew, Melbourne, Australia on March 23 at 2 pm.
They seemed to be roiling, not moving much from overhead.
I’ve added some contrast to the images to show the complexity.
Experts – is this a rare could with a name?
There was little rain and little wind on the ground.
Topography flat, near sea level.
Do we see an emergent undulatus asperatus here, near the left pole in image two?
