Burning clouds are red clouds that appear at sunrise or sunset. Sunset clouds belong to the category of low clouds, which is one of the phenomena of atmospheric change. It often appears in summer, especially around sunset after a thunderstorm, in the west of the sky. Due to the strong evaporation on the ground and the great action of updraft in the atmosphere, the shape of fire clouds is ever-changing. The color of flame clouds is generally red, and the appearance of flame clouds indicates that the period of warm weather, abundant rainfall, lush biological growth and prosperity is coming.

How are sunset clouds formed?

When the sun just comes out or is about to set, the clouds on the horizon are often red, like burnt clouds. People call these red clouds sunrise and sunset clouds, and they are also vividly called "flaming clouds".

The sun is a mixture of seven colors: red, orange, yellow, green, cyan, blue and purple. Among these lights, red light has the greatest ability to pass through the air layer, followed by orange, yellow and green light, and cyan, blue and purple light are the worst. In cloudy morning or evening, the air layer through which sunlight passes is thicker than that at noon. Among them, yellow, green, cyan, blue and purple are exhausted after "walking" in the air not far away, and they can stick their heads out through the air layer and "dye" the horizon into red. This forms a burning cloud.
