What is the aperture around the sun?
Halo is a colorful or white halo or arc of light around the sun formed by cirrus clouds and cirrostratus, and the color bands are arranged in infrared purple. Solar halos are sometimes called "sun flail", including total halos and intermittent halos. According to experts, solar halo is an atmospheric optical phenomenon, which is formed by the refraction or reflection of ice crystals when sunlight passes through cirrostratus. When light enters the ice crystals in cirrostratus, it is refracted twice and dispersed into light of various colors in different directions. In fact, when there is cirrostratus, there are countless ice crystals floating in the sky. The ice crystals in the same circle around the sun can refract the light of the same color into our eyes, forming an internal infrared purple halo. When cirrostratus composed of ice crystals appears in the sky, one or more colored rings often appear around the sun, and sometimes many colored or white spots and arcs appear, which are collectively called halo.
The reason for its formation is that a cirrostratus composed of ice crystals appears at a height of 5000m. The ice crystals in cirrostratus will undergo physical changes such as refraction and reflection after being irradiated by sunlight, and the sunlight will be decomposed into red, yellow, green, purple and other colors, thus a huge colorful halo will appear around the sun.
There is also a folk proverb-the sun is dizzy at midnight, the rain is dizzy at noon, and the wind is dizzy at noon.
Question 2: What is the aperture around the sun? This is a solar halo. As the saying goes, it rains in the middle of the night and it is windy at noon!
Solar halo is an atmospheric optical phenomenon, which is formed by the refraction or reflection of ice crystals when sunlight passes through cirrostratus. When light enters the ice crystals in cirrostratus, it is refracted twice and dispersed into light of various colors in different directions. When there is cirrostratus, there are countless ice crystals floating in the sky. Ice crystals in the same circle around the sun can refract the same color light into people's eyes, forming a halo of internal infrared violet. When a cirrostratus composed of ice crystals appears in the sky, one or more colored halos of internal infrared violet centered on the sun often appear around the sun, and sometimes many colored or white light spots and arcs appear. These halos, spots and arcs are collectively called halos.
Question 3: Why do large apertures sometimes appear around the sun? This is a solar halo

The halo around the sun
Solar halo is a light phenomenon formed by refraction when sunlight passes through ice crystals in clouds, which surrounds the sun in a ring shape and is colored. The appearance of solar halo often indicates that the weather will change to some extent.
Solar halo is a rare astronomical phenomenon. "Solar halo" includes total halo and gap halo. Halo is a colorful (or white) halo or light arc around the sun formed by cirrus clouds and cirrostratus, and the color bands are arranged in infrared purple. Solar halos are sometimes called "sun flail", including total halos and intermittent halos. According to experts, the solar halo is formed by the refraction or reflection of ice crystals when sunlight passes through cirrostratus. When light enters the ice crystals in cirrostratus, it is refracted twice and dispersed into light of various colors in different directions. In fact, when there is cirrostratus, there are countless ice crystals floating in the sky. The ice crystals in the same circle around the sun can refract the light of the same color into our eyes, forming an internal infrared purple halo. When cirrostratus composed of ice crystals appears in the sky, one or more colored rings often appear around the sun, and sometimes many colored or white spots and arcs appear, which are collectively called halo.
When the viewing angle corresponding to the solar halo radius is between 22 and 46, people can observe the phenomenon of "solar halo" with the naked eye. The greater the ice crystal content in the cloud, the smaller the "halo" shape after sunlight refraction, and the more obvious the halo, which is convenient for people to observe; On the other hand, a "solar halo" cannot be formed, or even if it is formed, it cannot be clearly observed on the ground.
"Dizziness" mostly occurs in spring and summer. There is a folk proverb called "the sun is dizzy in the middle of the night and the moon is dizzy at noon", which means that if there is a solar halo, it will rain in the middle of the night, and if there is a lunar halo, it will be windy at noon the next day. Solar halo can be a precursor of weather change to a certain extent, and it may turn cloudy or rain when it appears. But there is no scientific basis to say that this phenomenon can predict the drought and flood of this year's climate.
Don't watch with the naked eye for a long time when the solar halo appears, so as not to burn your eyes.
Question 4: In recent days, there have been obvious colored apertures around the sun. Why? Halo is an optical phenomenon formed by the refraction or reflection of sunlight or moonlight by ice crystals suspended in the atmosphere. Aura is usually annular or arc-shaped, with seven colors: red, orange, yellow, green, blue, indigo and purple. The reflection of ice crystals irradiated by the sun on human eyes is called "solar halo", and the reflection of ice crystals irradiated by the moon on human eyes is called "lunar halo". Halo occurs when ice crystals in cirrus clouds appear in a specific shape and direction. According to their shapes and positions, these ice crystals can be produced around bright light sources, so we can see the rings around the sun and the moon. Halo can change color like a rainbow because its reflection and refraction are different. Usually the inner ring is red and the outer ring is purple. Similar phenomena include the rainbow itself and the pillars of the ice rainbow.
Question 5: What is the aperture around the sun called? It's called a solar halo.
Question 6: What is the name of the aperture around the sun? What is the omen? Call it a solar halo. It is said that this is a sign of heavy rain. I looked it up on the internet, and it turned out to be a solar halo and a lunar halo.
This kind of aperture around the sun or moon is called "halo", and in some places, it is called "cangue". The aperture around the sun is called "solar halo" and the aperture around the moon is called "lunar halo".
Cirrostratus sometimes appears at high altitude. This cloud is white and translucent, sometimes like a gauze, sometimes like a tangled silk thread, composed of some tiny ice crystals of different shapes. When light passes through these small ice crystals, the degree of refraction and reflection of all kinds of light will change its direction. Ice crystals on the same circumference around the sun can refract the same color light into our eyes, and the light spots in all directions are connected into an internal infrared purple halo. When the sun is strong, you can see two or three colors; When the sun is weak, you can only see white. Because the moonlight is very weak, the halo you see is often only white.
When you feel dizzy, there is usually no wind and thin clouds are floating in the sky.
The appearance of dizziness indicates that the weather will change. Because cirrostratus, which forms the halo, is the front of a rain cloud system, there will be high cumulus clouds and high-level clouds, and then it will rain in nimbostratus, often accompanied by strong winds. Generally, it is more likely to rain in the solar halo, and it is windy in the lunar halo.
Solar and lunar halos
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.
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."
Question 7: What is the phenomenon that there is an aperture around the moon? There should be two kinds of lunar halos, blue-green in the month and reddish-brown outside the month. This is a diffraction phenomenon. When light passes through small water droplets with similar wavelengths, the light intensity will be distributed alternately. This is diffraction. 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. 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." The blue-green flowers in Moon Bay and the reddish-brown flowers outside Moon Bay are diffraction phenomena. When light passes through small water droplets with similar wavelengths, the intensity of light will be alternately distributed, which is diffraction. If the outer ring is only white, it is that the halo is caused by light passing through cirrostratus, and it may rain.
