Meteorological problems, rainbows around the moon.
Also known as the "wind circle", moonlight is refracted by clouds, forming an aperture around the moon, which can be used as a sign of weather changes.
Possible consequences of certain symptoms.
Before the weather changes, we sometimes see one or more colored or white apertures around the sun or the moon, and the sunlight and the moon light seem to be much darker.
What's going on here? We call this aperture around the sun or moon "halo". The aperture around the sun is called "solar halo" and the aperture around the moon is called "lunar halo". This is a strange meteorological phenomenon. The color of halo is generally infrared violet.
Halo-the phenomenon that light is refracted by moonlight when it passes through ice crystals in clouds. The color is dizzy, and the interior is infrared purple.
The appearance of solar halo or lunar halo often indicates that the weather will change to a certain extent. Generally speaking, a solar halo means it may rain, while more lunar halos mean it will be windy. So there is a folk proverb: "The sun is dizzy in the middle of the night and the moon is dizzy at noon."
Lunar halo was called in ancient times.
