The morning glow shows how the weather is. What does the morning glow portend?

1, the morning glow indicates that the weather will turn cloudy and rainy. Because smog is the result of sunlight passing through the atmosphere around sunrise and sunset and being scattered by a large number of air molecules. The more impurities such as dust and water vapor in the air, the stronger the color. The morning glow before and after sunrise shows that there is a lot of water vapor in the atmosphere, and clouds have begun to invade this area, so it indicates that the weather will turn to rain.

2. In the early morning and evening, around sunrise and sunset, rosy clouds often appear on the horizon. This is because around sunrise and sunset, sunlight passes through the thick atmosphere and is scattered by a large number of air molecules. When sunlight enters the atmosphere, it will scatter when it meets atmospheric molecules and particles suspended in the atmosphere. These atmospheric molecules and particles themselves do not emit light, but because they scatter sunlight, each atmospheric molecule forms a scattered light source. According to Rayleigh scattering law, light with shorter wavelength such as violet, blue and cyan in the solar spectrum is most easily scattered, while light with longer wavelength such as red, orange and yellow has stronger light transmission ability. So we see that the clear sky is always blue, while the light above the horizon is only yellow, orange and red with longer wavelengths. After these rays are scattered by impurities such as air molecules and water vapor, the sky there will be colorful.

3. Before and after sunrise in the morning, you can sometimes see bright red brilliance reflected in the eastern sky or clouds, making the blue sky more magnificent. But before long, dark clouds soon filled the whole sky, and then it began to rain. On cloudy days, such as in the evening or around sunset, we see this bright red glow in the western sky or clouds, but it indicates that the weather will clear up the next day. This is the origin of "Don't go out at dawn and go to Wan Li Road at sunset".

4. The chardonnay seen in the sky before and after sunrise is called Chenxia, and the chardonnay before and after sunset is called Twilight. The appearance of the morning glow indicates that the water vapor and water droplets in the atmosphere will increase, and the clouds will invade the local area from the western sky, which can predict that it will turn rainy soon in the future. The appearance of the sunset glow indicates that the rain in the west has stopped and the weather has turned fine. Moreover, the bright red and golden red sunset often indicates that the atmospheric stability has improved, which can predict the future weather will turn fine.
