Is it a good sign that there are solar halos and colorful clouds in Beijing at the same time?

Since ancient times, people have believed that there are ominous and auspicious signs in this world, such as a very famous ancient poem? Xue Rui is a good year? It is said that the first snow after winter indicates a good year. In ancient times, an emperor specially set up an official post called Qin Tian Jian, who had the ability to look at the stars at night to calculate whether the signs of the country's national luck were good or bad. In modern times, many people are superstitious. They believe that if there are some phenomena, it must be a sign.

On June 8, a colorful cloud and a solar halo appeared over Beijing. Many citizens took photos and posted them online. It happened to be the second day of the college entrance examination. The citizens think this is a very good sign. Candidates were sure that their grades were excellent, but it was actually a beautiful misunderstanding and a common phenomenon in nature.

The reporter learned from meteorologists that these colored clouds and solar halos are the most common atmospheric optical phenomena. The reason for this phenomenon is that the ice crystals in the clouds irradiate and reflect the sunlight. This phenomenon usually occurs in cloudy weather, and that day happens to be cloudy, which is a suitable condition for solar halo.

On the morning of the 8th, some citizens took photos of colorful clouds, and colorful clouds appeared in Changping, Tongzhou and Chaoyang at noon and afternoon that day. And this colorful cloud, like a solar halo, is the most common weather in nature. Colored clouds appear because the ice crystals in the clouds refract and reflect sunlight, which separates sunlight into seven colors and rainbows. This kind of colorful clouds are usually presented by cirrocumulus or altocumulus clouds, so you can see that the colorful clouds are all pieces.

The cause of the solar halo is similar to that of the colorful clouds, but the solar halo is caused by cirrostratus, which is large enough to form a circle and cannot be disturbed by other clouds.
