Corresponding to the 12 news hexagrams of the Book of Changes: Heaven and earth negation hexagrams, it seems that yin and yang are half and evenly matched, but at this time, the yang energy weakens, the yin energy gradually increases, and the cold qi begins to gain the upper hand, so after the heat, it will feel very cool in the morning and evening.

The summer solar term falls on August 23 every year. According to the "Seventy-two Candidate Explanations of the Lunar Order": "Place, go, and the gas will stop here."

It means that the hot summer is coming to an end. Although the average daily temperature in the vast areas east and south of Beijing, Taiyuan, Xi'an, Chengdu and Guiyang in China and the Tarim Basin in Xinjiang is still above 22 degrees Celsius and is in summer, the number of cold air moving southward increases and the temperature drops gradually obviously.

In ancient China, the summer heat was divided into three phases: "one is the eagle is a sacrificial bird; Second, the heaven and the earth are the beginning; Three Hou Henaideng.

However, since South China is still basically controlled by the summer monsoon during the summer season, there are often weather with the highest temperature higher than 30 in the western part of South China and higher than 35 in the eastern part of South China. In particular, the low-altitude areas along the Yangtze River are more felt in the years when the drought continues"Autumn Tiger"of the aftermath.

The summer heat is the early stage of the transition of rainfall distribution in South China from more in the west and less in the east to less in the west. At this time, the rainfall in central South China is often the second highest of the year, which is higher than during the Great Heat or White Dew. Therefore, in order to ensure the use of water for farmland in winter and spring, it is necessary to conscientiously grasp the water storage work during this period.

In the plateau area, there will be continuous cloudy and rainy weather from summer to autumn equinox, and the production of agriculture and animal husbandry is unfavorable. Most of the southern part of our country is also the busy season for harvesting medium rice. In general, in the summer solar term, the sunshine in South China is still relatively sufficient, except for the western part of South China, there are not many rainy days, which is conducive to the cutting and drying of medium rice and the spitting of cotton.

However, there are a few years such as Du Shisuo"The dog days have passed, and the sun has turned into rain"The autumn rain will come early.

The 24 solar terms have "three summers", that is, the small summer solar term, the big summer solar term, and the summer solar term, which are in order of the beginning of the summer heat, the middle heat stroke, and the end of the summer heat. There is also a "beginning of autumn" solar term in the middle of the "three summers", and the summer heat is only after the beginning of autumn, and the heat is relatively long. The prolonged summer heat is good for crop growth and yield.

The ancients called the period from the beginning of autumn to the beginning of autumn before the autumn equinox "long summer".

"Dog days" involves the four solar terms of small heat, big heat, beginning of autumn, and summer heat, and when it comes to the summer heat, the dog days have passed or are nearing the end.

After the summer season, except for South China and Southwest China, the rainy season in most parts of China is about to end, the precipitation is gradually decreasing, and the rice is ripe and harvested. In particular, North China, Northeast China and the West Raid Danqiao North region should pay close attention to water storage and moisture conservation; Prevent drought during autumn planting and delay the sowing date of winter crops.

The cold and high pressure that began to affect China, under its control, formed a sinking, dry cold air, first announced the end of the rainy season in northeastern, northern, and northwest China, and took the lead in the most beautiful weather of the year - high and cool autumn.

During the summer season, it is only the Northeast and Northwest regions that really enter autumn. However, whenever cold air affects China, if the air is dry, it often brings windy weather, and if there is warm and humid air in the atmosphere, it often forms a decent autumn rain.
