What do black, gray and white in typhoon clouds mean? Black, gray and white in typhoon clouds are all simple meanings.

1. If the earth's surface is a clear sky area, the infrared radiation information emitted from the ground to space is observed by satellites, and the satellite cloud image is black and gray. The darker the black, the stronger the ground radiation and the better the weather.

2. When a place is covered with clouds and rain, the satellite observes the infrared radiation from the cloud top into space, which is white or grayish white. White indicates that the ground radiation is very weak, the temperature is very low, the cloud satellite image is very thick and dense, and the rainfall intensity is also very high.

3. The transition zone between clear sky area and cloudy and rainy area is usually covered by dark gray, gray and light gray clouds, indicating that there are clouds with different thicknesses and no obvious precipitation.
