What do the morning glow and the evening glow portend?

Morning glow means rain, and sunset glow means sunny day.

There is a folk saying that "the morning glow does not go out, and the sunset glow travels thousands of miles." In other words, the bright red light in the morning shows that there are many water droplets in the atmosphere, which indicates that the weather is going to turn rainy.

If there is a fiery red or golden sunset glow, it means that there is no cloud in the west, and the sunlight can be transmitted to form a sunset glow, which indicates that the weather will be fine. Colorful clouds sometimes appear on the horizon around sunrise and sunset. The chardonnay seen in the eastern sky around sunrise is called morning chardonnay, and the chardonnay around sunset is called sunset chardonnay.

In ancient times, there was a saying that "the morning glow does not go out, and the sunset glow travels thousands of miles". In fact, there is some scientific truth in this. Because the morning glow is mostly caused by cumulus clouds, it is very easy to develop into cumulonimbus clouds; Most of the sunset clouds are light cumulus clouds, which will not cause precipitation. Generally, it indicates that it will continue to be sunny in a certain range in the next few days, which is conducive to travel.

According to the scientific principle of sunset glow formation, the region and probability of its occurrence can be roughly predicted by building a model. At present, some young meteorological enthusiasts in China combine key factors such as meteorological cloud pictures, cloud boundaries, cloud holes, etc., and realize rough prediction of sunset clouds through data simulation.
