Why is it easy to see colorful auspicious clouds before 40 degrees high temperature weather?

Multicolored auspicious clouds are caused by the phenomenon that clouds and water vapor particles scatter sunlight. When the weather is hot, the water in the atmosphere will evaporate quickly and form more water vapor. When sunlight shines on these water vapor, colorful auspicious clouds will appear due to optical phenomena such as refraction, diffraction and reflection of light.
