What is the reason for the colorful auspicious clouds above the Forbidden City turret?

The colorful clouds above the turret of the Forbidden City are a typical "sunrise" phenomenon, which refers to the natural phenomenon that the sun's rays pass through the ice crystal structure in the clouds. Under the right weather conditions, sunlight and clouds form an appropriate angle. Through refraction and reflection, the water vapor in the clouds above separates the solar spectrum and scatters seven colors of light.

Clouds and clouds over the watchtower of the Forbidden City are full of wonders. The magical nature will always bring us amazing scenes, and we have to sigh at the magical nature's creations.

Japan-China relations and weather

There is a proverb among the working people in southern Fujian: "The baked wheat cake in the sky is getting smaller and the weather is not good." The so-called "baked wheat cake" refers to Japan and China. According to the old farmer, it will rain soon when this happens. I have observed Japan and China for 7 years and recorded the relationship between the changes in China and the weather.

It is found that the change from large to small (from obvious to vague) in Japanese-Chinese circle really indicates the weather change in the short term. If the next day's precipitation is predicted according to the changes of Japan and China in June of 1 year, the probability can reach 83-90%, and the possibility of light rain on the second day of1-April accounts for about 78% of the total precipitation times during this period. The reason may be that the wavelength of broadcasting is constant, and the change from large to small is the reaction of the average radius of cloud droplets changing from small to large.

A new scene in the northern night-colorful auspicious clouds appear over the watchtower of the Forbidden City. Netizen: It's so beautiful.
