The phenomenon you saw was infact desert dust. It came from africa. Swiss television just mentioned it in the news.

Haha just what i told you guy's wink_o.gif

But the next problem is...It's coming to here ( netherlands ) and I hate that red sandish dust mad_o.gif

@Ex-RoNiN: just check the Weather chanel and you will find the reason why it is like that tounge_o.gif

We get African dust storms here,usually in April-May, during a period called Hamsin.

Worst is what it does to your car, when the rain comes down.

That isnt comparable to what happened during the Gulf War to the cars now was it ?

Dunno about Israel but here our cars used to get all covered with black soot at night from the oil that maniac saddam burnt mad_o.gifcrazy_o.gif

No. During the Gulf war, we only had a little bit of extra dust from Saddam's scuds which, for the most part, were environment friendly. biggrin_o.gifrock.gifcrazy_o.gif

the red clouds are red because of the red light district here in Amsterdam. tounge_o.gif

Nah.. But I really think it has to do with the normal street lights.

A friend who reads astronomy explained a possible solution for me just the other day.

The suns rays are in all kinds of colour right? When no clouds/"clean" clouds are in sight the sky is blue, the suns red rays do not reflect on those. But when there are alot of "dirty" clouds around the red rays do get reflected, that is why sunsets make the sky red. And also one major reason as to why the sunsets in Japan are deep red.

Might not be a hundred percent correct as I had it explained to me at three AM wink_o.gif I'll talk to him again and see if I can get it straight.

You are close but not right. The phenomenon that causes shifts of colour/light on the sky has a name after the scientist that discovered it: John William Strutt Lord Rayleigh.

Here's a short explanation:

Quote[/b] ]RALEIGH SCATTERING

Raleigh scattering is the phenomenon in which light is scattered by objects small in relation to the wavelength of the light. For example, the scattering of sunlight by gas molecules in the atmosphere is caused by Raleigh scattering of blue light.

The red sky can also happen in the middle of the day because of other particles such as dust and polution.

If any of you have an empty aquarium at home you can simulate the sun, atmosphere and the variations of the light at home.

1. Fill up the aquarium with water and place black filt at the back of the aquarium.

2. Use a strong flashlight and point the lightbeam through the aquarium and towards the filt. The light on the filt will show up as white - as the sun would appear in space without an atmoshpere.

3. Pour a little milk into the water. The protein and fatt in the milk will provide particles - almost like particles in our atmoshpere. Now, watch the light from the side and it will show up as blue - like daytime atmosphere. If you are lucky and have the right light and the right amount of milk in the water you might even see the blue spreading a little from the beam and out in the water. If you look straight onto the beam it will however appear yellow just like the sun does when you try to look at it during daytime.

4. Pour some more milk into the water and you'll notice that the water will be denser with particles. This is what happends when the sun is low on the sky. The light from the sun hits our atmosphere (relative to where you are of course) from a sideway position - thus the light travels through more particles compared to when it shines from the top of your position. The light will now be more red - and this effect is almost the same as when the light hits particles caused by polution or dust.

The thing is that "white light" constists of several colours and they bend off when they hit particles in the atmoshpere. The blue light we see at daytime hits the particles and bounces around in our atmoshpere appearing like coming from everwhere.

Hope you got good enough answer as this was school knowledge when I was 14 years old tounge_o.gif

Remember to take care of the fish before you try this at your little brothers aquarium.

Reddish brown isn't all that weird. Back in '87 my city had a tornado rip through it and on the day of the tornado we had some really funky weather and green clouds. Yes... green clouds. It was screwed up.

... Just found these two quotes from the unsung sky pack thread:

Quote[/b] ]2. more sky colour appearing for some instance e.g. green ?(even it is not very realistic, but I like this.......hehe.....)

Quote[/b] ].  1.  The sky is too blue during dark raining day. (screen 1)

Nope. I've seen both

Not unrealistic at all. Heh.  rock.gif

Speaking of which. I wish that tornado for OFP was released. That "mod" thing that was supposed to come with it never got out.

Seriously? My friend learnt this at University (Astronomy basics I think) again, I didn't quite remember what he said to me so that is why it's incorrect. But now... I need some sleep....

As for someone living in Munich several years now, I can tell you that I have seen such a funky sky maybe once a year. I thought about taking a picture of it, but I was too busy (read: playing OFP tounge_o.gif )

And before you ask: this grainy cold white stuff that is currently falling from the sky and makes you slip on every step is just snow - nothing to fear my greek fellow tounge_o.gifbiggrin_o.gif

Volcanic eruption inspired The Scream

The Scream (1893) by Edvard Munch

Astronomers say a volcanic eruption that made the sky turn red was the inspiration for the lurid colours in Edvard Munch's famous painting, The Scream.

Very interesting Avon - I realy didn't know ( sad_o.gif and I have a degree in art history) .

I looked it up and found this from the National Museum:

Quote[/b] ]Jeg gik bortover veien med to venner - sĺ gik solen ned - himmelen ble pludselig blodrřd - jeg stanset, lćnet mig til gjćrdet trćt til dřden - over den blĺsvarte fjord og by lĺ blod og ildtunger - mine vćnner gik videre og jeg stod igjen skjćlvende av angst - og jeg fřlte at det gik et stort uendelig skrig gjennem naturen

Translated: I walked along the road with two friends and watched the sun go down - the sky suddenly became bloodred - I stoppet, leaned towards the fence deadly tired - over the blue-blackish fjord and town there were blood and firetongues - my friends continued on and I was left trembleling with anxiety - and I felt there went a large and neverending scream through the nature.

This must have been as "sent from heaven" for an artist so concerned about establishing a connection between the inner mind and the nature.

Note that the anxiety was something Munch was concerned with long before this painting was made (and the graphical works of the same theme) .

This is a recent conclusion. If you purchased your degree beforehand, you won't be tested on it. tounge_o.gif
