Yunfu, why is it sunny and rainy now?

In summer, sometimes the sky is cloudless and sunny in Wan Li, but suddenly it rains heavily. We call this rain summer rain. Sometimes the strong wind blows the rain in the distant clouds, but we can't see the clouds but see the rain. Sometimes showers come from clouds in the sky, and the clouds have dissipated before the rain falls to the ground. Of course, the range of showers in summer is small. Sometimes there is only a small cloud in the sky that doesn't cover the sun, but just above our heads, there will be a sudden heavy rain.

Sometimes there are many clouds in the sky, but if it doesn't rain, it will all dissipate after a while. This is not surprising, because clouds don't have to turn into rain to dissipate. It is often because the wind in the air blows them down, and the temperature at low altitude is relatively high. When clouds are heated, they turn into water vapor, so we can't see them.
