What weather does the lunar halo represent?

The halo of the moon represents some change in the weather, which indicates that it will be windy.

Halo is an optical phenomenon in nature, which is due to the refraction of ice crystals when the moon's light passes through the high and thin cirrostratus, so that the seven-color composite light is dispersed into an infrared purple halo or arc, which surrounds the aperture around the moon. Sometimes there is a gap in the lunar halo, and the direction of the gap is the direction of the wind. There is a folk proverb called "the sun is dizzy in the middle of the night and it rains, and the moon is dizzy at noon", which means that if the moon is dizzy, there will be wind at noon the next day. Therefore, the halo of the moon represents some change in the weather, which indicates that there will be wind.
