Why is the weather in Guangzhou so capricious? From a geographical point of view.

In spring, the strength of cold and warm air is equal, and cold and warm air meet over Guangdong to form frontal rain. In Zhaocun, Guangdong, there are many thunderstorms and windy weather in spring, and the temperature fluctuates greatly in spring. The reason is that the strength of cold air is equal, sometimes the cold air dominates and the temperature drops, and sometimes the warm air dominates and the temperature rises.
