Look at the clouds and understand the weather 50 words after reading

We live in all kinds of atmospheric images. On a sunny day, the sky is high and the clouds are clear, and the sky is blue; on a cloudy day, the sky is covered with dense clouds and the sky is gloomy; on a thunderstorm day, the dark clouds are overwhelming, with lightning and thunder... Changes in the weather are often reflected in changes in clouds, so people often say that "clouds are the sign of the weather." For a long time, people have gone through an arduous process of exploration in order to observe and predict the weather, and have accumulated the knowledge of "knowing the weather by looking at the clouds" and using instruments to detect the weather. However, the experience is not ideal. The emergence of meteorological satellites has basically solved this problem.

How does the Meteorological Guard work? Meteorological satellites are different from sounding balloons and term satellites. They do not directly use meteorological instruments for detection. They use aerospace remote sensing technology. Meteorological satellites use remote sensors at high altitudes to receive electromagnetic information radiated or reflected by the measured object, and process it into identifiable information. Images that reveal the nature, shape and dynamics of the object being measured. Meteorological satellites not only work during the day and night, but also use infrared radiation to detect. It has two outstanding works called "Visible Light Cloud Image" and "Infrared Cloud Image". At present, more than 120 countries across the country are using this technology. The satellite cloud images we see every day in TV weather forecast programs are the above two types of cloud images. Relying on high-tech detection tools such as meteorological satellites, humans are converting the " "The sky is unpredictable" was changed to "The sky is unpredictable".
