Let's not forget about "sprites" and "elves".

Sprites

"Sprites are large scale electrical discharges which occur high above a thunderstorm cloud, or cumulonimbus, giving rise to a quite varied range of visual shapes. They are triggered by the discharges of positive lightning between the thundercloud and the ground. The phenomena were named after the mischievous sprite (air spirit) Puck in Shakespeare's Midsummer Night's Dream. They normally are coloured reddish-orange or greenish-blue, with hanging tendrils below and arcing branches above their location, and can be preceded by a reddish halo. They often occur in clusters, lying 50 miles (80 km) to 90 miles (145 km) above the Earth's surface. Sprites were first photographed on July 6, 1989 by scientists from the University of Minnesota and have since been witnessed tens of thousands of times. Sprites have been mentioned as a possible cause in otherwise unexplained accidents involving high altitude vehicular operations above thunderstorms.

Elves

"Elves often appear as dim, flattened, expanding glows around 250 miles (402 km) in diameter that last for, typically, just one millisecond. They occur in the ionosphere 60 miles (97 km) above the ground over thunderstorms. Their colour was a puzzle for some time, but is now believed to be a red hue. Elves were first recorded on another shuttle mission, this time recorded off French Guiana on October 7, 1990. Elves is a frivolous acronym for Emissions of Light and Very Low Frequency Perturbations from Electromagnetic Pulse Sources. This refers to the process by which the light is generated; the excitation of nitrogen molecules due to electron collisions (the electrons possibly having been energized by the electromagnetic pulse caused by a discharge from the Ionosphere)."

Yeah I only found out about these a few months back too, and I work for the Weather Bureau, lol. I remeber reading about a case that happened in Carnarvon a few years back which was bought on by the presence of a roll cloud

Good job... oh, and........

What, no
green flash?


Sorry for being off topic but BTS requires extra log in (and it won't let me log in. ) Why is that thread about the green flash in a forum called "member art"? They are very good pictures of a comparatively rare natural phenomenon! That's pure *science* in my book.
BTW, I saw a green flash in Scheveningen, more than two years ago.

Anyway, great thread.

What do you think of the role of cosmic rays in cloud formation? And weather events in general. Also things like magnetar and gamma ray bursts. Before the bushfires our magnetosphere took a huge hit from a magnetar.

“Our clouds take their orders from the stars,” says the Danish scientist Henrik Svensmark. That's the amazing and provocative discovery
reported here. Most experts thought the idea was crazy.

The film records ten years of effort by the small team in Copenhagen that, in the end, solved the mystery of how the Galaxy and the Sun interfere in our everyday weather.


It's provocative because Dr Svensmark's revelations challenge the belief of most climate theorists that carbon dioxide has been the main driver of global warming. As a result he has faced never-ending opposition.

But strong support for the cosmic view of climate change comes from astronomer Nir Shaviv and geologist Jan Veizer. In the film they tell how the Galaxy has governed the Earth's ever-changing climate over 500 million years.

The Cloud Mystery is aimed at a wide audience. Astonishing pictures from our Galaxy, the Sun, and cloud formations are mixed with spectacular animations to simplify the science. Comments by astronomers, geologists and climate experts convey their sense of adventure, and give scientific weight to the discoveries presented. The audience is taken on a trip around the world, where scientists from Denmark, Israel, Canada, the USA, and Norway contribute to this exciting story.

Linking all the discoveries is the non-stop rain of cosmic rays – energetic particles from exploded stars that battle with the Sun's magnetic field to reach the Earth. Central in the story is an experiment in a Copenhagen basement. It showed how cosmic rays help to make chemical specks in the air on which water drops condense to make clouds.

The story concludes that clouds are the main driver of climate change on Earth.

The other day I saw an odd display in the sky. I've been looking for pictures online of anything similar, but can't find any. My friend and I were driving and we noticed on the horizon there were these beams of "light" that were placed perfectly apart and were each about the same width and looked like the japanese rising sun flag or a halved of the japanese imperial army flag (en.wikipedia.org...:War_flag_of_the_Imperial_Japanese_Army.svg)

It looked like how any kid would draw a sunset.. and it was my first instinct to say to my friend "wow the the clouds are making the sunset look insane" or something to that affect.. but then i realized the it was still fairly daylight out and the sun was setting behind us on the opposite horizon.

we both looked or a camera and talked about what it could be.. (and no, the mall hasn't invested in 6 or 8 new spotlights haha) i mean most likely it was reflections or something? but i cant imagine it being so perfect (the beams were darker blue than they sky and had very defined contrasted edges to the rest of the sky) but it seems like with the sun behind us and up above the beams should be furthest apart at the horizon and draw together in the sky but they were definitely coming from the "ground" up.

if i was better with photoshop i would recreate it. and it is one of those things thats majesty cant be explained.. rest assured had anyone reading this been there, they couldnt brush it off. this was dec 2nd (we live in ashland ky). we observed it for about 8 to 15 before it faded.

like i said.. most likely a one in a million natural occurence.. but it was just so perfect looking it had us talking and searching for an explanation (spotlights, refinery explosion, etc).. it really seemed like another light source but extended way to far into the sky and in the daytime (not to mention the width) or any man made source i can think of.

What you have seen are called anti-crepuscular rays. Its quite amazing to see them at almost an even spread, but with right clouds you can.

Here's a link....I cant be bothered to type out a full description as Im too drunlk

Asperatus clouds eh. Ive never heard them called that before. Over here in Australia they are known as Mammatus. They do make spectacular images though, half the time they dont even look real
