What kind of weather is the easiest to see colorful clouds and solar halos?

Generally speaking, it's easier to see colorful clouds and solar halos after the rain clears. At noon on the second day of the college entrance examination, the sky in Changping, Beijing was shocked by solar halo and colorful clouds at the same time. The scene is spectacular and beautiful. Although the appearance of solar halo and colorful clouds is only a natural phenomenon of ordinary light refraction, our country has experienced many ups and downs this year. I hope this is a good sign and everything will be fine in the future.

Caiyun? Refers to the natural phenomenon produced by solar rays and ice crystal structure in clouds, which is more typical? Daily chemical? Phenomenon. Under the right weather conditions, sunlight forms a right angle with the clouds. When sunlight passes through the clouds, the water vapor in the clouds above separates the solar spectrum through refraction and reflection, thus scattering seven colors of light. In the folk, it symbolizes good luck and can bring good luck to those who see it. There is also a folk saying that there are colorful clouds in the sky, chickens jumping on trees, dogs jumping on walls, snakes jumping on roads, toads jumping and so on. As an early warning before a major earthquake, it indicates that a major earthquake is about to happen. Of course, this is definitely not allowed.

Aura? Also known as the round rainbow, it is an atmospheric optical phenomenon, which is formed by the refraction or reflection of ice crystals when sunlight passes through the cirrostratus. When light enters the ice crystals in cirrostratus, it is refracted twice and dispersed into light of various colors in different directions. Most of them appear in spring and summer. It rains in the middle of the night and windy at noon. The proverb means that if there is a solar halo, it will rain at midnight. ? Aura? Also have and? Caiyun?

Buddhism believes that solar halo is the embodiment of Buddha's light. According to Buddhist scriptures, Buddha's light is the light from Sakyamuni's brow. There was a solar halo in Jiuxian Mountain in Dehua, which was called the wonder of Buddha's light. At that time, people stood on the mountain with their backs to the oblique sunshine and facing the veiled clouds, and they would see a colorful halo of red, orange, yellow, green, cyan, blue and purple intertwined in the periphery, and their shadows were reflected in the halo.
