The appearance of lunar halo shows what is formed, how and why.

Halo is an optical phenomenon. Like solar halo, what appears next to the sun is called solar halo, and what appears next to the moon is called lunar halo. Generally speaking, what does a lunar halo mean? Then, let's introduce you to the constellation knowledge. What does the lunar halo portend? How is it formed? What is the reason? The appearance of lunar halo indicates the appearance of solar halo or lunar halo, which often indicates that the weather will change to a certain extent. Generally, a solar halo means it may rain, and a lunar halo means it will be windy. Sometimes there is a gap in the lunar halo, and the direction of the gap is the direction of the wind. So there is a folk proverb: it rains at night when the sun is dizzy, it rains at noon when the moon is dizzy, and it rains when the moon is dizzy. How is the lunar halo formed? We call this aperture around the sun or moon a solar halo. The aperture around the sun is called solar halo, and the aperture around the moon is called lunar halo, which is a common meteorological phenomenon. The color of the halo is generally internal infrared violet, forming a colored halo. When the moonlight passes through the ice crystals in the clouds, the refracted light forms an aperture around the moon. Sometimes it has a silver hole. These "auras" are actually cirrostratus. We also said in science class that when cold air meets warm and humid air, it will form rain clouds. At this time, the sky is very cold, and the water droplets are frozen into hexagonal ice crystals. When the moonlight shines on these ice crystals at night, a lunar halo is formed. There are large and small circles in the lunar halo, which only appears at the edge of the moon. Phenomenon and effect: the sky is clear as water, and gradually, the fog rises. The clear jade plate is covered with shy cotton yarn, and a circle of ultraviolet and red colorful auras appears around it. From a distance, people are dreaming, confused, and the gas field is fluttering, revealing a mysterious meaning. Everything seems to be getting better. Psychology uses the natural phenomenon of lunar halo to describe that when people know something, they will have a good impression on it because of their personal mood or certain characteristics of the object, just like the lunar halo, and feel that its image is better and more perfect. But in fact, it is shrouded in the aura of thought, ignoring the shortcomings and deficiencies of the object. This is the most primitive and simple understanding of individual things. It is a cognitive way that emotional experience replaces careful direct observation and rational judgment.
