What is the Colour of cloud before rain?

Why do clouds go GREY?

So why are clouds sometimes grey? Cloud bases are often grey as a result of the same scattering that makes them white. When light is scattered in a cloud it usually is sent back upwards, or out to the sides of the cloud, making the tops and sides of the cloud whiter than the base which receives less light.

What do clouds look like before a storm?

The first type looks like spoonfuls of marshmallow cream or cool whip (cool whip = cumulus). These are Cumulus clouds and they are puffy. Cumulus clouds can look like animals or people.

Why cloud is black and white?

When clouds are thin, they let a large portion of the light through and appear white. But like any objects that transmit light, the thicker they are, the less light makes it through. As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.

What are black clouds?

A: Very dark looking or black clouds are probably those that contain a lot of rain in them and part of a thunderstorm, McRoberts adds. “In general, the severity of a storm is related to cloud height, which is why dark clouds are usually an indicator of bad weather.

Why are clouds white 10?

All the suspended particles in cloud have size very larger than the wavelength of visible light falling onto it. So, it suffers almost zero scattering. Hence the clouds which have droplets of water with a>>λ are generally white.

Why is the sky white?

The white appearance of the sky sometimes is due to the scattering of incoming solar radiation by large sized particles. Complete step by step answer: … As the scattering intensity is nearly the same for all wavelengths, to human eyes it appears white. Thus, the sky sometimes appears white.
