Why are there colorful auspicious clouds over Dali?

Yunnan is a beautiful place. There are many colorful clouds over Dali, Yunnan. The reason for this scene is a crystal structure change in the sun's rays and clouds. A natural phenomenon, also called solar slip, has a beautiful sight.

There is a beautiful scenery over Erhai Lake in Dali, called colorful Xiangyun, like colored silk. Because the weather is better, in the right weather, if the luminosity of the sun and the luminosity of the clouds form a suitable angle, the sun can directly shine through the clouds, which has the function of reflection and refraction. If the light spectrum of the sun is separated, seven colors of light will be scattered. If you want to know the reasons for the formation of colorful auspicious clouds, you should know that there is water in the atmosphere after the rain, and it is very rich. This atmospheric phenomenon occurs when the sun refracts.

Generally speaking, some water droplets will appear very thin when suspended in the sun, so the water droplets can orient the light, and the color will be combined with some light when coloring. There are some shallow dark lights and different colored lights below, so the performance effect is different because of the different color angles, and finally it becomes different color levels. The place far from the sun is lighter in color, and the place near the sun is thicker in color. Because of the uneven distribution of clouds, some clouds have irregular shapes and different colorful clouds will appear.

There are several surveys that can show this. First, clouds that are generally between 10 and 40 degrees from the sun will see this, and small water droplets are needed in the clouds to form uniform small water droplets. In mooring clouds, there are cumulus clouds, lenticular clouds, cirrocumulus and rare mother-of-pearl clouds, which can form colorful clouds, and such colorful clouds can only be seen on sunny days.
