What does summer solstice mean? Meaning and implication.

The summer solstice refers to the 10 of the 24 solar terms. The moral of this story is that hot summer is coming.

First, meaning.

The summer solstice is the 10 of the 24 solar terms. Fighting means noon; The yellow meridian of the sun is 90 degrees; June 2 1~22 of Gregorian calendar. On the day of summer solstice, the position where the sun shines directly on the ground reaches the northernmost part of the year, almost directly on the tropic of cancer. At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year.

For the Tropic of Cancer and its northern region, the summer solstice is also the highest day at noon in a year. The solstice in summer is the turning point of the sun's northward movement.

Second, meaning.

Summer solstice is the traditional "health preserving" period in China. People should pay attention to health care and keep a balance and moderation in diet, exercise and rest.

Summer solstice is an important period of agriculture. People should seize this opportunity to vigorously cultivate, not only to arrange the current farming activities, but also to make agricultural plans for the second half of the year. Summer solstice means that the hot summer is coming, so people should be prepared for the hot weather, pay attention to heatstroke prevention and prevent diseases such as summer heat.

Meteorological changes in summer solstice;

First, the vertical rod has no shadow.

Zhanjiang, Maoming, Yangjiang, Yunfu, Zhaoqing, Jiangmen, Foshan, Zhongshan, Zhuhai, Shenzhen, Dongguan, Huizhou and Shanwei, which are located south of the Tropic of Cancer in Guangdong Province, can be seen standing without a shadow twice a year.

People living in the Tropic of Cancer and its vicinity to the south can set up a pole in the sun from summer to noon a few days before and after, and observe how the "immediate effect" becomes "without a trace".

Second, thunderstorms.

During the summer solstice, the temperature is high, the sunshine is sufficient, the crops grow rapidly, and the physiological and ecological water demand is high in most parts of China. At this time, the precipitation has a great influence on agricultural output, and there is a saying that "raindrops are worth tens of millions in summer solstice". At this time, the precipitation in the middle and lower reaches of the Yangtze River can generally meet the needs of crop growth.

After the summer solstice, the ground is heated strongly and the air convection is strong, which is easy to form thunderstorms. This kind of hot thunderstorm comes and goes, and the rainfall range is small. Heavy rains may occur in some areas, which may easily lead to floods and even threaten people's lives and property. Attention should be paid to strengthening flood control.
