Why is the sunset glow in summer more beautiful?

I'm glad to answer for you: because there are more clouds in summer. The formation of sunset glow is due to the scattering of light by air. When sunlight enters the atmosphere, it will encounter atmospheric molecules and particles suspended in the atmosphere (and clouds are a collection of water droplets, particles or ice crystal colloids that stay in the atmosphere. ), it will spread out and form a beautiful cloud. So the more clouds, the more beautiful the sunset glow.
