Rare Asperatus Clouds Spotted in Central Texas - 04/08/14

Over the weekend, while attending a wedding in New Braunfels, I witnessed some unusual clouds.

Check out the pictures with this blog?  Have you seen these?

With several other people at the wedding admiring these rolling hills in the sky, I got a lot of questions on what type of cloud they were.

They had a somewhat pouched look which made me first think Mammatus.  However, Mammatus clouds are usually associated with thunderstorms, but there wasn't even rain in the area.

I talked with a few other Meteorologist friends, and we remembered an unclassified type of cloud that was getting a lot of buzz on the internet a while back called Undulatus Asperatus.  Sure enough, that is exactly what they looked like.

A study done by Graeme Anderson at Reading University scoured through records and found these clouds form in similar conditions as Mammatus clouds, but the winds at the cloud level cause it to shear and look more like undulating waves than sunken pockets.

In order to be officially classified, it has to be recognized by the United Nations World Meteorological Organization in Geneva. It's a slow process.  There hasn't been a new cloud classification since the 1950s.
