Why does the sun rise early and set late in some places?

It is a weather phenomenon that the morning glow never dies and the sunset glow travels thousands of miles. When you see the morning glow, try not to go out or stay indoors during the day, because there is a great possibility of morning glow and rain during the day. However, if you see the morning glow at night, you can go out to play as much as you like the next day, because the day after the morning glow at night is mostly a cloudless sunny day in Wan Li.

The so-called morning glow and sunset glow actually refer to the light reflected by the sun on the clouds. Light itself has three colors, also known as three primary colors, namely green, blue and red. Clouds are condensed by water vapor, and water itself has the function of refraction and reflection, so when sunlight shines through water, gorgeous colors will appear.

Besides water vapor, clouds also contain dust. The more dust, the redder the sunset glow. When water vapor and dust condense together, uneven thickness will occur. When light passes through clouds, some colors are dark and some colors are bright. When there are many colors, it means that there is more water vapor; When the color is heavier, it means there is more dust in the clouds.

Besides, the sun rises in the east and sets in the west. It rises in the east every day and then sets in the west. So when the morning glow appears, it means that the clouds in the east contain a lot of water vapor and dust. And the clouds are still gathering in the process of drifting. There is a sunrise in the morning. When the sun rises and floats above the residence, it will carry a lot of water vapor. When the water vapor reaches saturation, it will naturally cause rainfall.

The appearance of sunset shows that the water vapor has drifted from the sky to the west, and the water vapor will drift farther and farther, so the day after sunset must be sunny. If the color of the sunset glow is golden yellow, indicating that there is little water vapor and dust in the clouds, then it can be concluded that the atmospheric climate is very stable, and the probability of sunny day the next day is 100%.

This sentence should be a common saying summed up by the ancients to observe the weather. At that time, there were no weather detectors, and people could only observe the weather according to natural phenomena.
