There are no clouds in Wan Li, but the sky is blue, and it is still blue sky and white clouds. What kind of weather is the best?

The formation of clouds is mainly caused by water vapor condensation. Observing the shape of clouds can predict the weather.

"Blue sky and white clouds" can change the recent weather, such as precipitation; "Cloudless Wan Li" and "Blue Sky Wan Li" are really good weather.

Clouds with weather omen often have certain continuity, seasonality and locality in the evolution process. Clouds in the sky move from a distance in the order of cirrus, cirrostratus, stratosphere and nimbostratus, and gradually change from less to more, from high to low, from thin to thick, indicating that rainy weather is coming; On the contrary, if the clouds change from low to high, from thick to thin, and from layered clouds to scattered clouds, there will be no rainy weather. In the warm season morning, if there are isolated clouds (light cumulus clouds) with flat bottom and convex top in the sky, or white broken clouds (broken cumulus clouds) that move quickly, it indicates that the air in the middle and lower layers is relatively stable and the weather is fine.
