for our friends down under

[highteknology]

saw these photos on My Yahoo page this morning. they are these clouds called Mother of Pearl clouds. The clouds only form in temperatures lower than 80 degrees Celsius (-112 Farenheight).

[G-man422]

Sweet! so, they form when its under 112 deggrees?

[fredjacksonsan]

I think he meant -80C and -112F.

In general as you go higher in the atmosphere, the temperature decreases. About 3.5F or 2C per 1000 feet.

[G-man422]

Oh, i see now.

yeah my bad. that shit would have to be cold

[G-man422]

^ oh yeah, lol.

[vinnym86]

those look beautiful. i've always been enthralled by the pehnomena of nature

[AlbanyCartel]

Heres another nice natural phenomena:



They're called Fire Rainbows and are regarded as the rarest of all naturally occurring atmospheric phenomena.

^ that's so sick. something about nature still impresses me each time i look up at the sky. even in the middle of my back yard. i'll make an O shap in my hand so the only thing i can see in the sky, no man made things are visible. i'll stand there in awe. truly amazing.

another thing is the Aurora Borealis (spelling?) i always wanted to see that.

I believe aurora borealis can be seen from alaska and probably parts of Canada. But of course, you'd have to know when the conditions were going to be right for it to occur.

And that fire rainbow is teh shit! I'm hard pressed to say it pwns aurora borealis, but its close

edit: I take that back, aroura borealis > all

[RX-7 Steve]

That "fire-rainbow" is amazing! I have never seen anything like that.

Nature is so magnificent.

[highteknology]

the fire rainbow is by far more magnificent than the borealis in the sense that it rarely occurs. the borealis occurs farely rarely but the conditions for the fire rainbow to occur are more rare.

the borealis occurs when there is a magnetic storm. usually during an equinox, or in the 11 year sunspot cycle.

i love this picture

the fire rainbow occurs when the sun is at least 58 degrees above the horizon. the most important part about the fire rainbow that makes it rare is the fact that the ice crystals that the light refracts must be aligned horizontally, which is rare.

Magnificence by virtue of rarity, most definitely. If I ever get a chance to see a fire rainbow in my lifetime, I'll consider it milestone in my life. But judging purely on visuals I give it to the aurora for the numerous ways it can appear.

But after hearing the conditions required for the fire rainbow, its value value as a natural phenomenon skyrockets past the aurora

[highteknology]

true, but many people are going to base the phenomity (if that's a word) on the pure visual aesthetics of the borealis, which BY FAR outweigh the fire rainbow. i've seen little itty bitty parts of fire rainbows before, but nowhere near the enormity of the one posted in this thread.

Definitely not a word!
