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

Satellite cloud map.

In satellite cloud images, green represents land, blue represents oceans, and white represents clouds.

Satellite cloud images are images of the tops of clouds taken by satellites orbiting the earth at an altitude of hundreds to tens of thousands of kilometers. They are generally divided into three colors: white, green and blue. The rolling white area represents the clouds above the earth. The thicker the white, the thicker the clouds. Where the clouds cover or are about to cover them, there will be rainy weather. In winter, the northern Northeast and western Inner Mongolia are often gray and light white, but the image is static. These places indicate 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.

Since most of our country’s land is located in the middle and high latitudes, the direction of the upper air flow in this area basically moves from west to east. Therefore, we look at satellite cloud images every day, especially in winter and spring. , cloud systems generally move from west to east. When watching, we can roughly judge the recent climate changes based on the local geographical location, cloud coverage and movement, and combined with the weather forecast from the local meteorological station. In the summer weather system, due to the influence of the subtropical high pressure system, especially during the typhoon season, typhoon cloud activity moves from east to west. The typhoon on the satellite cloud map is distributed in a spiral cloud system with a black spot in the middle. This is the eye of the typhoon, or the center of the typhoon. Now you can look at satellite cloud images.
