What does the weather forecast think of satellite clouds?

In satellite images, green represents land, blue represents ocean and white represents clouds. Satellite cloud image is the image of the top of clouds taken by satellites orbiting the earth at an altitude of several hundred kilometers to tens of thousands of kilometers, which is generally divided into three colors: white, green and blue. Among them, the rolling white area represents the clouds above the earth. The thicker the white is, the thicker the clouds will be, and rainy weather will appear where the clouds are covered or about to be covered.
