What are the characteristics of summer solstice?

Convective weather

After the summer solstice, the ground is heated strongly and the air convection is strong, and thunderstorms are often easy to form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. People call it summer rain over the mountains. Liu Yuxi, a poet in the Tang Dynasty, skillfully used this weather to write a famous poem: Rising in the East and Falling in the West, the Tao is sunny or sunny. The heavy precipitation brought by convective weather is not always as beautiful as described in the poem, and it often brings local disasters. In his poem "Summer Rain", the poet Xu Shuxin also described the thunderstorm weather in summer appropriately: sitting on the platform in summer, frogs are chirping and cicadas are attacking the dust. The golden gong sounded like a thunderbolt, and the cold rain hit the face like money.

Rainstorm weather

In most cases, during the summer solstice, the middle and lower reaches of the Yangtze River and the Jianghuai basin are rainy and frequently rainstorm, which is easy to cause floods and even threaten people's lives and property. Attention should be paid to strengthening flood control.

Jianghuai Meiyu

The solstice season in summer is the rainy season in Jianghuai area. This is the yellow ripening period of plums in Jiangnan. The air is very humid. Cold and warm air masses meet here, forming a trough of low pressure, which leads to continuous rain. In this weather, the utensils are moldy and the human body feels uncomfortable. Some mosquitoes breed quickly, and some intestinal bacteria are easy to breed. At this time, we should pay attention to drinking water hygiene and try not to eat cold food to prevent the occurrence and spread of infectious diseases.

High temperature weather

Like the winter solstice, the summer solstice is also a solar term reflecting the changes of the four seasons. Astronomy stipulates that the summer solstice is the beginning of summer in the northern hemisphere. After the summer solstice, although the direct point of the sun began to move south from the Tropic of Cancer, the days in the northern hemisphere began to shorten gradually. For the Tropic of Cancer and its northern area, the height of the sun began to decrease day by day, but because the heat radiated from the sun to the ground is still more than that radiated from the ground to the air, the temperature will continue to rise in the future, so there is a saying that the summer solstice is not too hot. Characteristics of solar terms in solstice summer

In ancient China, the summer solstice was divided into three stages: one was the decomposition of antlers; Second, wait for cicadas to start singing; Third, wait for Pinellia ternata. Although elk and deer belong to the same family, the ancients thought they belonged to yin and yang. The deer's horn faces forward, so it belongs to Yang. On the solstice of summer, Yin Qi was born, and Yang Qi began to decline, so the front antlers began to fall off. However, the elk is cloudy, so it falls off at the corner from winter to Sunday; After the solstice of summer, the male cicada fluttered and sang because of Yin Qi's feeling; Pinellia ternata is a shade-loving herb, named after it was born in swamps or paddy fields in midsummer. It can be seen that in the hot summer, some yin-loving creatures began to appear, while positive creatures began to decline.
