The difference between flying sand and stones and wind and cloud discoloration

The degree and form of expression of the two are different.

Flying sand and stones and changing colors are descriptions of bad weather, but the degree and form are different. Sand and stones flying refers to the wind rolling up dust and stones, which makes the vision blurred and the air turbid, causing serious visual obstacles.

The color change of clouds refers to the change of clouds in the sky. Due to the changes of meteorological conditions such as air pressure and temperature, various strange colors such as red, purple and blue appear in the sky, and the scene is very spectacular.
