What does a burning cloud look like?

In the early morning, when the sun just comes out, or when the sun is about to set in the evening, the clouds on the horizon are often red, like fire.

People call this kind of red cloud flaming cloud, also called morning glow and sunset glow. Sometimes, without clouds, the sky will appear fiery red, which is called burning the sky. ?

We already know that sunlight is a mixture of red, orange, yellow, green, cyan, blue and purple. The wavelengths of these colors of light are different. The red light wave is the longest, followed by the orange light wave, and the purple light wave is the shortest.

Molecules in the air and countless tiny dust and water droplets float in the air, which can disperse the colors of the sun. This is called scattering.

The shorter the wavelength of light waves in the sun, the easier it is to scatter light such as purple and blue. The longer the wavelength, such as red and orange light, the less likely it is to scatter.

Extended data:

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.
