Is colorful auspicious clouds rare?
Colorful auspicious clouds are rare.
Colorful cloud refers to the natural phenomenon caused by the solar rays and the ice crystal structure in the cloud, which is a typical "sunrise" 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.
At 1 o'clock noon on August 8, 219, "Colorful Xiangyun" appeared over Hangzhou. On June 28th, 22, "Colorful Xiangyun" appeared in the sky of Haikou. On October 27th, 22, "Colorful Xiangyun" appeared over Lijiang. On November 1st, "Colorful Xiangyun" appeared over Erhai Lake.
on January 23rd, 223, a colorful Xiangyun landscape appeared in the sky in Eryuan County, Dali Prefecture, Yunnan Province. On July 11, 223, a large piece of "colorful auspicious clouds" appeared over Zhanjiang city, and passers-by stopped to appreciate and picked up their mobile phones to shoot. On July 21, 223, it rained in Wuhan. After the rain, the colorful Xiangyun landscape appeared in the sky of Wuhan, which was clearly visible to the naked eye.
The reason
This is an atmospheric phenomenon that the atmosphere is rich in water and sunlight refracts after rain. When sunlight passes through a thin cloud suspended with water droplets, the water droplets make the passing light diffract in different directions, and the diffracted light interferes with each other, and bright light will be seen at the junction of light waves, and the light at the offset will be dark.
The diffraction angles of different colors are different, and the bright areas of one color light appear in the dark areas of another color light, gradually forming a color order. The farther away from the sun, the lighter the color. Because the clouds are distributed in irregular sheets, colorful clouds with irregular sheets are produced.
formation conditions: clouds located at 1 to 4 degrees from the sun; Clouds are thin clouds with uniform water droplets, such as cumulus clouds, cirrocumulus, especially lenticular cloud, and rare ones such as mother-of-pearl clouds will form very bright colorful clouds; A sunny day.
