The reason why the morning glow never dies and the evening glow runs around the world

The reason why the morning glow doesn't go out and the evening glow travels around the world is that the morning glow represents the rain cloud, and it may be raining, so it is not suitable to go out. The sunset glow means that the rain clouds have left and it won't rain in the future.

The sunrise in the sky means that there is already a lot of water vapor in the atmosphere and clouds in the air. Due to the movement of clouds, the weather conditions may be unstable, which may lead to rainy weather. Moreover, the temperature is low in the morning. With the rising of the sun, the heat will be further enhanced, and the convective movement such as water vapor will be strengthened, which will easily lead to rainy weather.

When the sunset appears, the sun will be far away from the horizon, the thermal motion will be reduced, the convection motion will be weakened, the air layer will be stable, and the originally formed clouds will dissipate, so the weather conditions will be better that night. At the same time, the brilliant sunset also means that there are no clouds in the western sky, so that the sun shines all the way to the eastern sky. Then when the cloud moves from west to east, it will basically not affect the local weather.

Does the proverb "Don't go out at sunrise, but it takes thousands of miles at sunset" make sense?

China is located in the middle and low latitudes, and the planetary wind belt and pressure belt are westerly belt, subtropical high belt and northeast trade belt respectively. Among them, the westerly belt is located in the north, the easterly belt is located in the south, and the central region is a subtropical high belt. Every year since the spring, the subtropical high zone will move northward. Prior to this, China was in the westerly belt, and the weather system kept moving from west to east.

However, in summer and autumn, South China will be affected by tropical cyclones from the ocean, and there will be more typhoon weather. Limited by the subtropical high in the western Pacific, the weather system will move westward again. When tropical cyclones form on the ocean surface, they will absorb a lot of water vapor, which will directly lead to abnormal sunny and high temperature in the coastal areas of South China before the typhoon comes.

Therefore, from this situation, the sentence "Work at sunrise and travel thousands of miles at sunset" still has certain scientific basis, but it is mainly in line with the weather conditions in northern China, not suitable for southern China, and its predictability is very local.
