Can you judge the weather in a certain place according to the satellite cloud picture? How to judge?

The surface of the earth is a clear sky area, and the infrared radiation information from the ground to space is observed by satellites, which is black and gray; The darker the black, the stronger the ground radiation and the better the weather. 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; The whiter the color, the weaker the radiation, the lower the temperature, the thicker and denser the cloud system, and the greater the rainfall intensity. The transition area between clear sky area and rainy area is dark gray, gray and light gray cloud system, which indicates that there are clouds with different thicknesses and no obvious precipitation. People often see cloud systems with different shapes from satellite images broadcast every day. Meteorologists call it cloud system, which is actually the representation of various weather systems in cloud images. For example, people can see at a glance that the typhoon in summer is a huge spiral cloud. Some people call it "flying butterfly" of the atmosphere. It rotates counterclockwise at the speed of strong winds of tens of meters per second, and attacks the coast of China at the speed of tens of kilometers per hour. Because of the satellite cloud image, it was discovered at the beginning of its generation, so the level of modern typhoon forecast has been significantly improved. In the past, there was no meteorological record on the ocean surface, and the meteorological radar erected along the coast could not detect it. When the typhoon approaches the coast, its intensity, size, speed and direction are completely unknown to meteorologists, so how can it be accurately predicted?

Another major cloud image system in summer is a large black-gray cloudless area in the northwest Pacific, which is the protagonist of summer weather-the western Pacific high. It is usually a very irregular oblate circle, spanning the eastern part of Taiwan Province Province to the central and eastern parts of Chinese mainland. The deeper, wider and stronger the black color is, the higher the temperature is, and the longer the stable control time is. People call it a "black hole" figuratively. Most of the high-temperature heat waves in the middle and lower reaches of the Yangtze River in summer are "pranks" made by it.
