Words about the weather

1. It's sunny on rainy days, but it shines on the top without rain

This sentence means that the horizon is especially bright, which means it will continue to rain; On the contrary, if the horizon is dark and the zenith is bright, it is a sign of sunny weather. On rainy days, as a result of air disturbance, the water vapor and dust on the ground are blown to the sky, so the head-up visibility is particularly good, while the vertical visibility is bad, which is the brightness of the horizon.

The gloomy zenith is a harbinger of rainy days. When the atmosphere is stable, all the water vapor and dust are concentrated at low altitude on the ground, so the visibility at the head-up level is bad, while the visibility at the vertical level is excellent, so the zenith is bright and the ground is flat and gloomy. Since the atmosphere has become stable, it won't rain any more.
