What is the symbol of colorful clouds in the sky?
The appearance of colorful clouds in the sky is the refraction of sunlight and light produced by ice crystals in clouds, especially like rainbows in the sky after rain. The principle of colorful clouds is the same as that of rainbow. Under the right weather conditions, the sunlight forms an appropriate angle with the clouds. When sunlight passes through the clouds, the water vapor in the clouds separates the solar spectrum through refraction and reflection, thus scattering seven colors of sunlight.
Clouds are rainbows, which usually appear after rain. They are very beautiful. They are a natural phenomenon. After the rain, people see an illusion similar to a mirage through sunlight and light refraction, understand?
When there is more water in the atmosphere, the refraction of light by the atmosphere will happen, but it happens in the clouds. Before the earthquake, nature's forecast: colorful clouds in the sky, chickens on trees, dogs climbing over walls, snakes on the road and toads jumping around; It means that there will be a big earthquake, and the longest time will not exceed 24 hours.
