What is the name of the weather software that observes the direction of dark clouds?

In satellite images, green represents land, blue belt 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. In winter, in northeast China and western Inner Mongolia, it is often gray and light white, but the image is still there. These places represent snow on the ground, not clouds in the sky. The green color on the satellite cloud image represents the land and the blue color represents the ocean.

Because most of China's land is in the middle and high latitudes, the upper air flow in this area basically moves from west to east, so we look at satellite cloud pictures every day, especially in winter and spring, and the cloud system generally moves from west to east. When watching, you can judge the recent general climate change according to the local geographical location, cloud cover and movement, combined with the weather forecast of the local meteorological observatory. In the summer weather system, due to the influence of subtropical high system, especially in typhoon season, the typhoon cloud system activities move from east to west. The typhoon on the satellite cloud image is distributed in a spiral cloud system with a black spot in the middle, which is the typhoon eye, that is, the typhoon center. Can you see satellite images now?
