Everyone see things in the clouds. People, animals, Christ on the cross, UFO’s, angels, and even schizophrenically imagined chemical attacks by contrails. You name it, somebody has seen it. So when I was prodded with a news item that said “new cloud type defined” I was thinking “uh oh, here we go again”. It is a lot like cyclomania, as humans tend to assign patterns to randomly ordered observations of nature. Looking for meanings in the clouds isn’t much different than looking for meanings in the alignments of the stars and planets.
From ChattahBox and The UK Telegraph:
(ChattahBox)—Meteorologists around the world have taken notice of a new storm cloud on the horizon, literally. And if they have their way the dark and choppy cloud will take its rightful place among its more famous cousins, cumulus, cumulus, cirrus and nimbus.
Cloud gazing Meteorologists first noticed the stormy and billowy formation floating over the Scottish Highlands and above Snowdonia, Wales. The unique gray storm cloud was also spotted over Australia, the cornfields of Iowa and high above the Arctic Sea off the coast of Greenland.
A group in England dedicated to cloud watching, the Cloud Appreciation Society, became quite excited when viewing numerous photos of the new storm cloud floating in the atmosphere.
The Cloud appreciators describe the cloud as “…a bit like looking at the surface of a choppy sea from below,” said Gavin Pretor-Pinney, founder of the Cloud Appreciation Society, and the first man to identify the new cloud.
The Royal Meteorological Society has named the new cloud, “Asperatus,” the Latin word for rough, since the cloud has the appearance of a rough, choppy ocean.
The Royal meteorologists are now attempting to have Asperatus officially recognized by the UN’s World Meteorological Organization in Geneva to have it included in the International Cloud Atlas.
If the meteorologists are successful, this would mark the first time a new cloud was officially recognized since 1953.
I have seen clouds like this, but did not see them as being a new classification. Thus a little trouble with the idea of making an entirely new classification for this cloud, a sub classification perhaps would be more appropriate, especially since this cloud does not appear to inhabit the middle and higher levels of the atmosphere.
Here are the existing classifications:
| Latin Root | Translation | Example | ||
| cumulus
stratus cirrus nimbus | heap
layer curl of hair rain | fair weather cumulus
altostratus cirrus cumulonimbus |
Classifications
High-Level Clouds
Cloud types include: cirrus and cirrostratus.
Mid-Level Clouds
Cloud types include: altocumulus, altostratus.
Low-Level Clouds
Cloud types include: nimbostratus and stratocumulus.
Clouds with Vertical Development
Cloud types include: fair weather cumulus and cumulonimbus.
Other Cloud Types
Cloud types include: contrails, billow clouds, mammatus, orographic and pileus clouds.

So for “asperatus” I could see maybe “stratoasperatus” but not “altoasperatus” since there is no evidence of them at the high altitudes, and clouds at that level tend not to be rough edged.
I actually hope WMO doesn’t accept this ploy for attention by the Cloud Appreciation Society, if they do, it could open an avalanche of new cloud classification applications, we may see pitches of the most absurd kind.
For example, here’s another one from the Cloud Appreciation Society:

“Altostratus Obamus” perhaps?
People see all sorts of things in the sky, if this new one is accepted, the petitioning for WMO recognition of new cloud types would never end.

There’s two wave-systems (mountain lee waves) interfering in that photo, which often have associated rotor clouds this looks like rotor to me.
The Cloud Appreciation Society???????????????
Oh, man………………….
Gemini –
You will get new ideas from the sky and become fabulously wealthy.
We had a stunning example of this in January inland from Timaru. Started out as mamatus and then developed the swirls and shears in the large scale. Never seen it before tho.
Surely the Dorset Doughnut is actually a chemtrail disappearing up its own orifice?
That’s a Photoshop image if ever I saw one.
Let’s just dump the u-tube age and get back to reality… please.
It’s the Thirty First of May not April the First?
Clearly AGW is producing new kinds of angry clouds. These ones undoubtedly will be discovered to accelerate positive feedback.
[snip – cumulonimbus mammatus is the word you are looking for]
How is this any different than an Altocumulus mackerel sky? I’m no meteorologist but that was the first thing that occurred to me when I saw it.

I remember seeing clouds like these back in the 1970’s in the SF Bay Area. These are nothing new and do not need a new classification.
Very nice images!

With an apology to William Wordsworth:
I wondered lonely toward a crowd
When all at once I saw a cloud
Above the lake, above the trees
Can we name it Asperatus, please
Sang the CA and RM societies
Fluttering and dancing in the breeze.
Of course, due to global warming…or HE being manifested among the clouds (of course dark ones).
Perhaps, those cloud were a characteristic of Maunder Minimum, so they could be named Svensmark-Asperatus Clouds.
Choppy clouds?
That’s multiple wave formation produced by undulating terrain, as any glider pilot will tell you. Quite common over Wales too.
.
That is quite a picture. Reminds me of this:
http://www.vangoghgallery.com/catalog/Painting/508/Starry-Night.html
I have two new candidates, Cirrostreakus (formed from the spreading out of contrails), and Cumulosteamus, that visible low level cloud seen condensing near power plants.
Asperatus?
Give me a break! These people have way too much idle time.
Off Topic:
I have noticed that 90% of the adds on this site are from alarmist organizations or groups (I just got a 400×300 flash ad peddling carbon offsets).
A not-so-subtle statement on the amount of money that can be made peddling alarmism. Maybe it is time to stop worrying about “Big Oil” and start worrying abount “Big Green”.
I can’t believe no one has said this yet! They look like flying sheep to me. Or maybe ducks… or kittens…
We now return you to your regularly scheduled programing.
Clouds often mirror the landscape.
In this case we see lenticularis clouds at the horizon.
These clouds mark the rising of the air current when the wind meets a mountain or mountenous terrain.
Some times these clouds also occure when a windsheer takes place above condensation level.
You would see a cumulus cloud with a Lenticularis cloud on top of it.
If the air is turbulent, the underside of the cloud would take the form of a mamatus.
No need for futher classifications.
We have seen it all.
You’re right Ralph Ellis.
This glider pilot has flown in wave numerous times. Often smooth air as you get a magic escalator ride to high altitudes. Then the clouds look smooth. Sometimes there is turbulence and I’ve seen clouds like those in the photo. You can then see the turbulence cells moving through the cloud. Rotor is usually much more ragged looking.
Looks more like somebody had a little fun with their image editing software…
Wonder what kind of clouds they have in New York? A frost warming is up for most of the state until Monday. Pretty late in the year for frost.
