Why does the sky turn red at night? 30

The red neon lights of the city and the orange street lights are refracted by the red side of the sky, and the red side of the sky is the well-lit highway in or near the direction of the city.

Also, only red is seen because red light is highly foggy.

See it in the city, the city lights are refracted. I also often see that it is related to the level of pollution in the city.

It's definitely not sunset, and it can't be sunset, they just want to score. It's caused by too many city lights. When you go into the wilderness, you can't see it, it's dark. If you don't believe me, you can check it out.

The linear propagation nature of light and the reflective nature of light.

It means that it will rain the next day, or it may just be sunset.

The fact that the sky is red at night on a rainy day is associated with the increasing number of artificial lights on the planet.

The increase in artificial light has caused light pollution, which has made the night sky redder than before. On a night after the rain, the low altitude is covered with clouds, and the longer wavelengths of artificial light (red light) are scattered back to the Earth, making the sky appear red.

A study by German researchers shows that today, the sky is 18 times brighter on cloudy nights than on clear nights, which makes the cloudy night sky bright and red after rain. Sometimes, after rain, the sky also becomes clear and cloudless, and because there are no clouds, shorter wavelengths of artificial light are more easily scattered, and the night sky becomes bright and blue.

The sunlight travels along the horizon for a long part of the atmosphere, and most of the blue glass beads are blocked by the air net, bouncing aside, and only the red glass beads reach our eyes unhindered. That's how the morning and evening sky turns red.

However, the higher the sun rises, the shorter the path of light through the atmosphere, and the blocking effect begins to wane. The sky is brightening and the stars are dimming. When the first rays of sunlight showed their faces on the horizon, we went home like Count Dracula, we avoided the day and waited for the next night.

Celestial bodies appear redder from Earth than from space because redder wavelengths from celestial bodies penetrate the atmosphere more easily than bluer wavelengths to reach the ground.

The red color in the sky at night is not a fire cloud, it may be because you are in a city, and the city lights shine on the cloudy low clouds and become red after reflection and scattering, which shows that your city is more heavily polluted.

If you're in the countryside, you won't be able to see the colors on cloudy nights.

Tomorrow will be a big sun. If the sky is red in the morning. It's going to rain.

Don't go out in the morning! The sunset travels thousands of miles!

Said it was going to be dark tomorrow and it was time for dinner.

The color of the sky is generally red in the evening.

The reason why the sky we see during the day is blue is because the atmosphere scatters light with a characteristic characteristic: light with a shorter wavelength is easily scattered, and a longer light is not easily scattered. Blue light has a short wavelength, so it is easily scattered, and the sky appears blue.

In the evening, because the sunlight has to pass through the thick atmosphere, the blue and purple light are scattered, leaving the red light and orange light to enter our eyes through the atmosphere.

Therefore, the color of the sky in the evening is generally red.

However, it cannot be ruled out that the change in the density of the atmosphere during abnormal weather will have a special impact on light, so abnormal weather should still have an impact on light.

But it seems to be an indication. It's a bit unreasonable, it's possible that there will be abnormal weather first and then turn red in the evening.

Hello, glad to answer for you. At night, the sky is red and it is a sign that tomorrow will be sunny. If the sky is red at night, it will be a big sun tomorrow, and if the sky is red in the morning, it will rain that day.

In the morning and evening, around sunrise and sunset, there are often colorful glows. Both morning and evening glows are formed due to the scattering of light by the air. Scattering occurs when sunlight hits the atmosphere and encounters atmospheric molecules and particles suspended in the atmosphere.
