Rosy clouds refer to the colorful clouds that appear in the sky at sunrise or sunset, which is a kind of atmospheric optical phenomenon.
Depending on the time of occurrence, it can be divided into:
1. Morning glow - rosy clouds at sunrise
2. Sunset glow - rosy clouds at sunset
Formation principle: When sunlight passes through the atmosphere, it is scattered by air molecules, water vapor and dust. The blue and violet light with shorter wavelengths are scattered away, leaving warm-colored light such as red, orange and yellow to illuminate the clouds, creating gorgeous colors.
Additional cultural notes: In Chinese culture, rosy clouds are often used as a poetic metaphor for beautiful things or auspicious signs. The phrase "rosy clouds at dawn" is particularly cherished.
