Hmm... sounds correct I think. Just reinforce a bit from my understanding. Clouds that are grey contain a larger amount of water which will be able to block...

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?

allentyb SG

because the sun is setting….............

It should be the clouds reflecting the lights on the ground bah…

darkfuryex SG

out of all the replies..i can understand none…and clouds reflects light? ....?

MooKu SG

reflect...? more like... are illuminated by the lights...

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.

Eiizumi SG

Because of heat I think. Heat = Infrared so = red.

gigabyte14 SG

because i said so Laughing

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 student Rolling Eyes Laughing

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...

darkfuryex SG

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?

tut4nkh4m3n SG

aurora beams created by other life forms outside earth

MohamedF SG

Hmmm... wild theory here... when its going to rain, the sky is full of moisture... and the moisture is reflecting the light from Singapore...

aiglosicicle SG

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....

apples SG

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

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

"As cumulus clouds formed, often grey due to the impurities in the air, is a tell-tale sign that rain might be coming..."
U saying clouds are grey due to impurities in the air? As a result of the impurities, it make the cloud rain??

the.owl SG

ya lor, what light distortion from the moonlight, this kind of BS also have.

M551Sheridian SG

u know why red? cos not blue of course!
