The colorful clouds appeared in Bijie, Guizhou, like a "rainbow hat" like a cloud.

Science Fiction Network August 18 (Qin Yingying) On the evening of August 17, there was a beautiful colorful cloud over the city of Bijie City, Guizhou. Seeing the beautiful scenery of the colorful clouds, the classic lines of Zixia Fairy in the classic movie "Journey to the West" starring Zhou Xingchi are even more echoed. "My intention is a hero. One day he will step on the colorful clouds and wearing a golden armor to marry me."

According to the staff's explanation, this phenomenon is because the sunset shines on a rainy cloud, and the water vapor is sufficient in the rain clouds. The water vapor reflects different colors. This phenomenon will occur.

This cloud color is a rainbow -like cloud, and the 幞 (Fú) cloud is formed by the rising air flow to raise the warm and humid air, so it covers the Genting like a hat.

Rainbow -like clouds are the natural phenomenon of summer summer. During the development of strong accumulation clouds or accumulated rain clouds, if there is a large level of humidity above the Genting, the water vapor will be raised and condensed by the cloud body ascending airflow, like the "headscarf" of the strong cloud, so it is named after幞 幞 幞. If the height of the sun is appropriate, it can be diffracted by cold water drops or ice crystals in the shaped cloud, and the diffraction rainbow can be formed.

"Colorful Clouds" appear, at least 3 conditions are required: the angle of cloud and sunlight needs to be about 10 degrees to 40 degrees; small ice crystals or small water droplets contained in Yuncai should be uniform, and it should be thin and convenient for the sun, such as Gao Jiyun, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds, such as high clouds. Curly clouds, etc.; The weather is clear, and the visibility is better.

From the perspective of meteorological experts, "colorful clouds" are not uncommon, and their causes are very similar to people who are more familiar. The "colorful cloud" is very similar to the cause of the rainbow. Rainbow refers to the water droplets shot to the air in the air, and the light is refracted and reflected, and finally forms a curved colorful spectrum on the sky.

Rainbow appears, there are more water droplets and less dust in the air; at the same time, there are few clouds to block the viewing line, and the sun is not strong. Therefore, when it turns sunny after the rain during the day, it is the most prone to rainbow. When the sun is shining at a low angle behind the observer, as long as there is a small droplet in the air, such as the water fog sprayed when the flowers and even people are poured by people, they may "make" the rainbow.

The same is the refraction or reflection of the sun in the air. The difference is that the "colorful cloud" is the optical phenomenon that occurs through the obvious but not too heavy cloud layer.
