Summer climate characteristics and related solar terms;

I. Climate characteristics:

In China, the coastal areas were heated inland in May, and a low pressure formed in the southwest caused the southwest monsoon, which reached the coastal areas of China in May. At this time, the northeast monsoon is blocked by the southwest monsoon, and it is rarely affected in summer.

In May, the weather in the north is still very cold. The cold air in the north meets the southwest monsoon in the south, forming a trough of low pressure in the South China Sea, which is the beginning of the rainy season in Guangzhou. By July, the subtropical high reached the vicinity of the Yangtze River basin in China with time, and rainy weather appeared in the Yangtze River basin.

Summer is the best season for the vigorous growth of many crops, and sufficient light and suitable temperature provide necessary conditions for plants. Most areas will be affected by low pressure and the climate is relatively stable. But the ocean near the equator will form a typhoon, which is easy to damage the surrounding area.
