Have You Seen An Undulatus Asperatus Cloud?

Undulatus Asperatus - Clouds of Armageddon?

The breathtaking undulatus asperatus cloud looks very like stormy ocean waves, and is rather disorientating to see as these waves are upside down in the sky!

I have been very fortunate to have seen an asperatus cloud walking to work on a muggy humid morning. As I rounded the corner I looked up and the sky made me stop in my tracks!

The billows of the asperatus cloud I saw looked as soft and smooth as ripples of silk. I didn't have a camera with me so grabbed my cell phone and took as many photos as I could!

This page looks at how this beautiful and newly classified cloud is formed, along with a few of my photos. I hope you will find the Undulatus Asperatus as amazing as I do!

The Undulatus Asperatus is a Newly Classified Cloud - The first cloud identified since 1951!

The founder of the Cloud Appreciation Society, Gavin Pretor-Pinney, is the person responsible for initially bringing this cloud to the attention of the Royal Meteorological Society as a potential "new" cloud. All clouds are classified into 10 major groups, with varieties and species. The last cloud to be classified and named was the cirrus intortus in 1951 - so this was big news for weather fans!

After founding the Cloud Appreciation Society in 2005, Gavin Pretor Pinney was inundated with wonderful photos of clouds from all over the world and one particular cloud kept catching his eye and that he couldn't identify.

After bringing the Asperatus to the attention of the Royal Meteorological Society, they then presented the data about this cloud to the UN's World Meteorological Organisation in Geneva. In June 2009, the Undulatus Asperatus was officially classified and listed in the International Cloud Atlas.

Take a look at this fantastic article from the Royal Meteorological Society, which gives the in depth scoop on the process of identifying the Undulatus Asperatus cloud.

Undulatus Asperatus Facts - Learn how, why and when these clouds are formed

  1. The species of this cloud is "undulatus" which means "wave" In Latin. The variety of the cloud is "asperatus" which means "roughened" so the name literally descibes how this cloud looks, like rough waves!

  2. This is a low cloud and is seen at about 2000 meters (6000 feet).

  3. Despite their stormy end-of-the-world-is-nigh appearance, these clouds do not produce rain or a storm. They are most likely to be seen following convective thunderstorm activity.

  4. Asperatus clouds are formed by warm and cold air meeting, this causes a turbulant effect. The British newspaper, The Telegraph uses the metaphor of vinegar and olive oil meeting in a great article about this cloud, which describes the transition very nicely! There is some disagreement about this though from scientists, it is also believed that Asperatus can form when dry air meets moist air.

      Saw these clouds over Syracuse, NY one afternoon in February about 25 years ago. They were very strange, and most resembled the first picture on this page. Seen near the horizon from a distance (they must have been overhead a few miles off), they looked like alternating light and dark wavy lines, piled on top of each other like an endless strudel. Never saw them before or since.

      I went to take my son to school on Feb 20th and was amazed to see the clouds. I had never seen clouds like this before. I immediately took my cellphone out and snapped a few pics. I live in Fort Worth, Texas.

      Here is a link to a time lapse of the Undulus Asperatus clouds that Philip Grey was talking about. I only live a few miles north of him in Hopkinsville,Ky. http://youtu.be/x6h_SrmNru8

      They start to form at the :26 sec mark. They are awesome to see in motion.

      We had a wonderful formation of Undulus Asperatus this morning, at around 8:15 a.m., Aug. 13, 2012 in Clarksville, Tenn.

      Unusually for the type, these formed ahead of thunderstorms that produced high winds and intense downpours throughout the area. Pictures of this beautiful sight can be seen at my newspaper's website at http://www.theleafchronicle.com/apps/pbcs.dll/gall...|galleriespic&nclick_check=1

      FYI, I currently work as a military reporter for my local paper located near Fort Campbell, Ky.

      I was formerly a US Air Force weather observer and also worked for several consulting firms operating weather stations in Philadelphia, Pittsburgh and St. Louis. Cheers!

      I have seen them twice. Once in 2009 in Highland, California, and the second time was Aug 1st, this year over Lake Michigan out of Manitowoc, Wis. where we were out trolling on the lake. Thought I would never see them again after 2009. My Flickr page has both sets listed. http://www.flickr.com/photos/nights-are-forever/ ...if link doesn't work, my Flickr ID is nightsareforever to search.

      As appearances go, they do not seem to be a severe weather cloud. Only when the base is obscured is significant precipitation falling. These appear to be middle layer clouds.

      Just saw my first undulatus asperatus. It was quite cool looking. Make me feel like the world was upside down. It was very beautiful and eerie at the same time. I live in Central NY near Utica so it looks like this phenomenon is moving east.

      Are these clouds seen in Portland, Maine on October 19, 2011 undulatus asperatus? Sorry for the advert at the beginning of the video: http://www.wmtw.com/video/29539928/detail.html

      Nothing natural about these clouds. They bring torential cloudbursts and are always preceded by chem trails. The more trails the heavier the cloud cover.
