Why is the sun particularly dazzling in winter?

In summer, when the temperature is high and the air is humid, it is easy to form clouds at high altitude (not when the airflow sinks when it rains, but when the airflow rises, the air cools to form clouds). When sunlight is scattered, the sunlight we see is not so strong. Explanation: If the water in the air is supersaturated, the condensate will be too small and will reflect and refract light. When there are few water droplets, only a small amount of light is reflected and refracted, just like countless small light sources, so the sky we see is not black as seen in space. When there is enough water vapor to completely reflect and refract sunlight, we can't see the sun, so we have what we call white clouds. When there is more water vapor, we completely use up the sunlight just by reflection. This is a dark cloud.

In winter, the temperature is low and there is little water vapor in the air. This scattering effect is small, and the "illuminance" of Taiziyang is greater, which is more dazzling to the eyes. At the same time, you should find that the sky in summer is brighter than in winter.
