What is the phenomenon of colored circles of light around the moon?

Colored circles of light around the moon are a phenomenon of lunar halos. Lunar halo is an optical phenomenon in nature. It is due when the rays of the sun or moon pass through the high and thin white clouds (cirrus.

Cirrostratus or Cirrocumulus.

, the color circle formed by the refraction of ice crystals, the color arrangement order within the infrared violet. The circle of light that appears around the sun is called the solar halo.

The circle of light that appears around the moon is called a lunar halo. Moonlight appears at night. Halo can be divided into "small halo" and "large halo", "small halo" is 22 degrees of halo, and "large halo" is 46 degrees of halo.

The small halo is a light red inner ring with a light red inner circle with a radius of 22 degrees and an occasional purple or white ring with a luminous body as the center and an outer circle, and the sky inside the halo is significantly darker than the outside of the halo. The large halo is a halo with an angular radius of 46 degrees, which is very rare and generally darker than the small halo.

Colored circles of light around the moon are a phenomenon of lunar halos. Lunar halos are formed by the refraction of moonlight through a thin cloud composed of hexagonal ice crystals when the angles of the ice crystals are arranged vertically. The appearance of a lunar halo indicates that the weather will change.

Generally speaking, the moon is invisible at night when there is a lunar halo, and the weather does not improve until the next night. In addition, the phenomenon of the parhelic moon also forms colored apertures. The principle of the mirage moon phenomenon is similar to that of the lunar halo, but the mirage moon phenomenon requires the simultaneous participation of water vapor and moonlight in the formation process, so the mirage moon phenomenon will only occur in areas with high humidity.

The circle of light around the moon is the "wind circle", also known as the lunar halo. Lunar halo is a light phenomenon formed by refraction of moonlight through ice crystals in clouds, forming a colored halo with inner infrared violet. The appearance of solar halo or moon halo often indicates that the weather will change to a certain extent, usually the solar halo indicates a high probability of rain, and the lunar halo mostly indicates that it is going to be windy.

At night in the north, the moon sometimes appears to be enveloped by circles, which the locals call the wind circles, and the larger the wind circles, the stronger the wind will be the next day, which is the phenomenon of wind circles. The sun is haloed with three more rains, and the moon is haloed at noon. However, it is not necessary to be windy and rainy every time there is a dizziness, and it must be analyzed according to the development of the cloud.

In general, when there is a lunar halo, it is less likely to rain than when there is a solar halo, and it is mostly windy.

Colored halos around the moon are the phenomenon of lunar halos. Lunar halo is an optical phenomenon in nature. It is a colored circle of light formed by the refraction of ice crystals when the light rays of the sun or moon pass through high, thin white clouds (cirrus, cirrostratus or cirrocumulus), and the colors are arranged in an internal infrared violet order.

The circle of light that appears around the sun is called the solar halo, and the circle of light that appears around the moon is called the lunar halo. Moonlight appears at night. Halo can be divided into "small halo" and "large halo", "small halo" is 22 degrees of halo, and "large halo" is 46 degrees of halo.

The small halo is a kind of inner ring with a light body as the center and an angle radius of 22 degrees, and the outer ring is occasionally purple or white, and the sky inside the halo is obviously darker than the outside of the halo. The large halo is a halo with an angular radius of 46 degrees, which is very rare, and the halo is generally darker than the small halo.

It's a moon halo.

When the moon halo passes through the cirrostratus clouds in the upper sky, it is refracted by ice crystals, so that the seven-color composite light is dispersed into a ring or arc of light with inner red and outer purple limbs, which creates a circle of light around the moon.

The weather proverb "The moon is faint and the wind is windy, and the foundation is moist and rainy", which refers to the change of weather, which originally means that the moonlight shines on the clouds and a halo appears, and the wind will blow; When the foundation stone is wet, it will rain.

Brightness. The moon itself does not emit light, only reflects sunlight. The brightness of the Moon varies with the angular distance between the Sun and the Moon and the distance between the Earth and the Moon, and the brightness of the Full Moon is more than ten times greater than that of the upper and lower strings.

The average brightness of the Moon is 1 465 000 of the luminance of the Traveling Sun, and the range of brightness varies from 1 630 000 to 1 375 000. The brightness on average at the full moon is equal. It gives the earth an average of lux, which is equivalent to the illuminance of a 100-watt electric lamp at a distance of 21 meters.

The surface of the Moon is not a good reflector, its average albedo is only 9% of the excitation, and the remaining 91% is absorbed by the Moon. The albedo of the moon sea is even lower, about 7%. The albedo of the lunar highlands and craters is 17%, and it looks like the mountains are brighter than the moon sea.

The distance from the Moon to the Earth is about 1 400 of the distance from the Earth to the Sun, so the Moon is as large as the Sun when viewed from the Earth.

The phenomenon of colored halos appearing around the moon is known as moon halos or moon halos. It is an optical phenomenon that usually occurs when clouds contain ice crystals. When moonlight passes through ice crystals and is refracted and reflected, reflected, and scattered, a colored halo is formed.

These colored halos usually appear in colors such as red, orange, yellow, green, blue, purple, etc., similar to a rainbow. The appearance of the moon's rings depends on factors such as humidity, temperature, and the shape and size of ice crystals in the atmosphere. This phenomenon is uncommon, but in the weather conditions of Tejo, colored halos around the moon are sometimes observed.

It is a beautiful and magical natural landscape that brings visual enjoyment.
