why wehn it is going to rain at night..the cloud are red ?
-
as title..u see ah when it is going to rain in the morning or afternoon it is dark clouds..but when at night it is red? actually orange-ish red...can anyone explain to me?
-
because the sun is setting................

It should be the clouds reflecting the lights on the ground bah...
-
out of all the replies..i can understand none...and clouds reflects light? ....?
-
reflect...? more like... are illuminated by the lights...Originally posted by jetabt767400:It should be the clouds reflecting the lights on the ground bah...
Most of the streetlights in SG are orange, therefore the clouds appear orangey.
It's not because it's going to rain so they're orangey. -
Because of heat I think. Heat = Infrared so = red.

because i said so

good riddance

Question
Why does the red color appear at the horizon during sunset?
Answer
The red colour in the sky at sunset (and sunrise) is due to an effect called Rayleigh scattering. There is a similar form of scattering called Mie scattering which is responsible for the white colour of clouds.
Particles in our atmosphere that are approximately the same size as the wavelength of visible light cause the white light from the sun to scatter and split into individual components. Oxygen and Nitrogen (the main components of our atmosphere) scatter violet and blue light due to their small size. This is why the sky appears to be blue in the day time, especially at midday when the Sun is closest to us.
During sunrise and sunset the distance that the light has to travel from the Sun to an observer is at its greatest. This means the a large amount of blue and violet light has been scattered so the light that is recieved by an observer is mostly of a longer wavelength and therefore appears to be read. -
whoa lao anyhow bullshit like that also can, must be an arts studentOriginally posted by Eiizumi:Because of heat I think. Heat = Infrared so = red.

At night where got red cloud...??? Only evening... even when we see the sun has set, the earth is round and the angle of light is still casting on the clouds... -
no i i said when it is GOING to rain...and at night the sky is dark blue one..only when it is going to rain AT NIGHT and it gets windy and all then it will turn orange-ish red...why?Originally posted by MohamedF:

aurora beams created by other life forms outside earth

Hmmm... wild theory here... when its going to rain, the sky is full of moisture... and the moisture is reflecting the light from Singapore...Originally posted by darkfuryex:no i i said when it is GOING to rain...and at night the sky is dark blue one..only when it is going to rain AT NIGHT and it gets windy and all then it will turn orange-ish red...why? -
i think its due to the sun's rays that reflects off the clouds, because the red coloured clouds are always very high in the sky.

Law of physics lah...
As cumulus clouds formed, often grey due to the impurities in the air, is a tell-tale sign that rain might be coming...
As in the day, cumulus clouds appear to be grey, but at night, the clouds would look like reddish, actually it's due to the light distortion from the moonlight.... -
haha... u seem like an expert smoker... got a lot of chimalogy terms and theory but doesn't sound logical leh. Don't know whether to believe u or not? Can ask uOriginally posted by dork3d:Law of physics lah...

So many physics law... which one u are u referring?

U saying clouds are grey due to impurities in the air? As a result of the impurities, it make the cloud rain?? -
ya lor, what light distortion from the moonlight, this kind of BS also have.Originally posted by apples:haha... u seem like an expert smoker... got a lot of chimalogy terms and theory but doesn't sound logical leh. Don't know whether to believe u or not? Can ask u

u know why red? cos not blue of course!

Impurities is the source of why it gives rain clouds (cumulus clouds) grey colour look...
As at night as moonlight shines across the atmosphere into the clouds, distortion of lights through the impurity particles reflect out like a prism effect, thus making the cumulus clouds at night look reddish...

Its red because I say so, now you all can STFU.
-
You prefer them to be green?
-
its red cuz i happy
-
eh... reflect light is the same as being illuminated har?
