There are colorful auspicious clouds floating over Fuzhou, Fujian. How did this phenomenon come into being?

After the rain, rainbows will appear. Some people found colorful clouds over Fuzhou, Fujian. While everyone is rushing to enjoy the beautiful scenery, they are also curious about how colorful clouds are formed. After everyone heard that colorful auspicious clouds appeared over Fuzhou, Fujian, many photographers and online celebrities rushed to the scene to shoot. The natural phenomenon caused by the solar rays and the ice crystal structure in the clouds, namely the colorful clouds, is a typical Japanese-Chinese phenomenon.

In the right weather, sunlight and clouds form an appropriate angle, so that sunlight will be refracted and reflected when it passes through the clouds, separating the water vapor in the clouds above from the light spectrum of the sun, thus scattering colorful light. In fact, the color of light is not necessarily seven colors, just because in everyone's impression, the rainbow is seven colors, but? Seven? It is also a number that everyone likes, which will form the name of colorful auspicious clouds.

It's the season now, and there is more rain. After the rain, the air is rich in water molecules, which is also the phenomenon of sunlight refraction. Sunlight passes through clouds with suspended water droplets. At this time, water droplets will be diffracted in different directions by light, and the diffracted lights will interfere with each other. Light waves will produce brighter light at the junction and weaker light at the offset, so different colors of light will be diffracted at different angles. The closer to the sun, the stronger the sunlight will be, so the color will be deeper. The farther away from the sun, the color will gradually fade, so clouds of different colors will be produced.

However, the emergence of colorful auspicious clouds also requires certain conditions, which must be after rain and sunny days. Moreover, there is also a requirement for the angle of the cloud, which must be 10~40 degrees. Many people think it is lucky to see Xiangyun, so many people will rush to see Xiangyun with their own eyes.
