Re: Why are clouds so dark when there is rain?
|
When it is raining, there is sufficient water vapor in the air in the clouds to block out the majority of the sun's rays. This results in a dark color being given to the bottom of the cloud. The color patterns with clouds in general, whether white, gray, or plain old dark, are a function of the diffusion of light by the water molecules in the clouds.
