What does the cloud have to do with the weather?

Clouds refer to water vapor rising into the sky. When the weather is clear and the temperature is high, the water on the surface evaporates into the air, meets cold air at high altitude, and condenses and connects in a large area, forming the clouds we see now.

The thinner and whiter the cloud, the thicker and darker the cloud.

These clouds are full of water ions and charged. The thicker the clouds, the more charge. When two clouds collide, lightning and thunder will appear.

At the same time, the water vapor in the cloud meets a large area of cold air and forms water droplets. If the water drops crystallize too much, they will fall if the buoyancy can't bear it, forming rain, snow and hail.

Of course, wind is the catalyst. If the clouds gather quickly, the white clouds turn into dark clouds quickly, or the dark clouds move fast, it must be windy at high altitude. Similarly, the surface wind speed will not be too small.
