Oz, theres some more Asperatus cloud here - are they the same as Mammatus?

Whatever the case they certainly do look a bit freaky.

Cheers.

Im not sure if they are the same or not. They do look a bit different from Mammatus clouds.

I will do a search and see what i come up with

Ok, I was quick, this from wiki

Undulatus asperatus (or alternately, asperatus) is a rare, newly recognized cloud formation, that was proposed in 2009 as the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization.[1] The name translates approximately as roughened or agitated waves

I did my training before 2009 so no wonder I didnt know about it, lol. Some cloud enthusiasts and some NOAA scientists are trying to get it added as an official cloud type with the WMO

Here's another one (not my photo) and I have only seen it once in my life.

Ice crystals in the air causing every light to create a beam shooting straight up into the sky:

If this is stepping in on your territory, it's fine with me if you want to pull the post. When I saw it I was living in a rural area with few lights, so at first we weren't sure what we were seeing. Even crazier was that the headlights from cars were causing the same effect. It was breathtaking!

No, no

Thanks for posting that!!

Its absolutely stunning

Thank you, I think that's it.
What I saw was much more uniform though, which made it look very unnatural.

Which one were you talking about?

I think I missed something there

Ahh.. sorry. The one I was replying to was the "anti-crepuscular rays"

The lower atmosphere and surface of the Earth

A more normal type of cloud forms at the base of the Earth’s
plasma blanket in the summer polar mesosphere regions. Located at an altitude of 85 kilometres, such a cloud is the highest on Earth and can be seen only when darkness has just set in on the planet. Hence, clouds of this kind have been called noctilucent clouds. They are thought to be composed of charged and possibly dusty ice crystals that form in the coldest portion of the atmosphere at a temperature of 120 K. This unusual medium has much in common with dusty plasmas in planetary rings and other cosmic systems. Noctilucent clouds have been increasing in frequency throughout the 20th century and may be a forerunner of global change.

Here are some neat clouds mentioned in this thread by Roadblockx.



They were identified by TrueAmerican as Roll Clouds in the thread.

Pretty spectacular looking.

Im stuck here at work on Christmas Day for 6 hours so I thought I might add a couple more

Kelvin-Hemholtz Waves

These waves within cloud are good indicators of severe wind shear over a short vertical extent.

They occur near areas where an inversion layer has winds of different speeds and/or directions. The upper sections just above the inversion layer generally have wind speeds greater than the layer below the inversion, as the moisture rises the change in wind speed and air density (of the inversion), force the air to move in waves similar to the mechanisms that create ocean waves.

Hey Oz, I don't know if this quite qualifies for this thread, but I wanted to share something I just learned about this year.

Derecho

A derecho (from Spanish: "derecho" meaning "straight") is a widespread and long-lived, violent convectively induced straight-line windstorm that is associated with a fast-moving band of severe thunderstorms in the form of a squall line usually taking the form of a bow echo. Derechos blow in the direction of movement of their associated storms, similar to a gust front, except that the wind is sustained and generally increases in strength behind the "gust" front. A warm weather phenomenon, derechos occur mostly in summer, especially June and July in the Northern Hemisphere. They can occur at any time of the year and occur as frequently at night as in the daylight hours.

I know I would not be happy seeing one of these coming toward me

[edit on 25-12-2009 by ZombieJesus]

I liked how lightning rolled out like a doughnut ring in the
NASA videos.
Who knew.

Just took a couple of pictures myself

A few of a halo, yet to identify which one but I think its a circumzenithal arc, and also some good ones of kelvin-hemholtz waves.

Try and get them up shortly

What would you call these?

Are they Chemtrails / Contrails ,or something else?

Excellent thread Oz, S&F for sure.

I have never seen most of these phenomena.

God we have boring weather in Britain!

Well, seeing as I dont believe in the existence of chemtrails, I would naturally call them contrails. There is also a large amount of cirrus cloud in the picture

Great thread! Thank you for posting. I love learning about the weather and our skies reactions. I have many pictures of sunsets and some of them are so amazing. The reflections of light are stunning. I wish I knew how to share pictures on here.

Inpressive post i really like it those Atmospheric Phenomenen Identyifying- List. Thanks for share it.

It is odd but in nature there is an explanation for everything, even alien technology can be explained in scientific terms just not known to us yet.

I do find the phenomena's interesting to look at.

Oz... thank you very much for showing us the interesting world above! great thread great references S&F for you sir!
