Quick Answer: Are rain clouds GREY?

Why do rain clouds look GREY?

It is the thickness, or height of clouds, that makes them look gray. … The tiny water droplets and ice crystals in clouds are just the right size to scatter all colors of light, compared with the smaller molecules of air that scatter blue light most effectively. When light contains all colors, we perceive it as white.

Why does the sky turn gray?

A: On hazy days, large particles in the air make the sky appear gray or even white, McRoberts explains. “These larger particles tend to scatter more wavelengths of light in the color spectrum,” he says. … This phenomenon is called Mie scattering. To sum it up, the way light is scattered determines the color of the sky.”

Do altostratus clouds rain?

Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. … However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto- stratus deck.
