Why is the weather so changeable in summer?

Because most parts of China are located in the northern hemisphere and belong to tropical, subtropical and temperate monsoon climate, summer is affected by solar radiation and summer monsoon, and it is usually hot and rainy, and it is sultry before rain. However, after rain, precipitation will take away a lot of heat because there is no direct sunlight, thus lowering the temperature, so the temperature difference between before and after makes people feel that the weather changes rapidly.
