It often rains in Britain, but why is the air not as good as some cities in the south of China?

Because of the different climate, Britain belongs to temperate maritime climate, which is mild, humid and rainy all year round, with little change in four seasons. South China is dominated by tropical and subtropical monsoon climate, with high temperature and rainy summer and mild and little rain in winter.

Britain's climate is mild and humid, usually the highest temperature does not exceed 32℃, and the lowest temperature is not lower than-10℃. The average temperature in Britain 1 month is about 4℃~7℃, and in July it is about 13℃~ 17℃, so you need to wear a coat when you go out in the morning and evening. Every year except July-September, the seasons at other times are relatively cold. In addition, the weather in Britain has another feature, that is, it is changeable in one day, sunny and rainy. Therefore, the weather has also become one of the topics of British people after dinner.

In southern China, the tropical monsoon climate is characterized by high temperature all year round, dry season and rainy season. The precipitation is above 800 mm, and there is more precipitation on the windward slope of the mountain. The southern region is greatly affected by the summer monsoon, and the rainy season is longer.

Every May, the summer monsoon lands from the coast of South China, and the rainy season begins. From June to July, the summer monsoon forces strengthened and moved northward, forming a quasi-static front between the Yangtze River and Huaihe River, and the rainy weather continued, mainly affecting the middle and lower reaches of the Yangtze River and Huaihe River Basin. Summer drought is easy to form in July and August. In September, the rainfall front moved south to this area, and after 10, the cold air force was further strengthened, the summer monsoon moved out of this area, and the rainy season ended. In addition, the southwest region is often affected by the southwest monsoon.
