It's windy in the north, and the temperature fluctuates. It's rainy in the south and sunny in the south.

China is a vast country with diverse climate changes. It is windy in the north, and the temperature drops suddenly, which is mainly caused by the high terrain, low air pressure and the interaction of cold and warm air masses in the north.

There is less rain in the south and more sunny days in the south, which is related to the topography and climate characteristics in the south. The south is low-lying, with high atmospheric pressure and humidity. There are often heavy rains in summer in the south, so there is more rainfall in the south.

For the gale cooling in the north, people need to pay attention to keep warm, keep warm against wind and prevent colds and other diseases. At the same time, we also need to pay attention to prevent sudden weather, such as storms, lightning and other weather disasters.

For the phenomenon of little rain in the south and sunny days in the south of the Yangtze River, people need to pay attention to rational use of water resources, strengthen water resources management and guard against the influence of high temperature weather in the south. At the same time, it is also necessary to rationally plan and utilize irrigation water sources to ensure agricultural production and urban water demand.

In a word, different climatic characteristics have certain influence on people's life and production. We need to take corresponding preventive measures according to the local climate characteristics to ensure the safety of people's production and life.
