summer treatment on the auspicious day of certification in 2020? The summer treatment solar term from the end of August to the beginning of September when the temperature drops is not enough to describe it only by the beginning of the decline of the temperature. Lower temperatures are only one of these phenomena. The reason behind this phenomenon is that the direct point of the Sun continues to move southward and the solar radiation weakens; Second, the subtropical high retreated southward by leaps and bounds, and the Mongolian cold high began to be eager to try, punching and kicking.

the subtropical high dominated by the southern "autumn tiger" in summer, although it retreats southward, it will not easily give up its dominance and retreat to the sea of the Western Pacific. In the southern region under its control, people who feel a trace of cool autumn often feel the hot weather again at the end of the summer. This is a real "autumn tiger". For areas out of three volts and suffering from severe summer drought, if they continue to be controlled by the subtropical high, it is often easy to form continuous drought in summer and autumn, which greatly advances the fire prevention period in autumn, so we need to be vigilant. It should be said that the middle and lower reaches of the Yangtze River often usher in a crisp autumn and sunny spring after the end of the autumn tiger weather, but it will be after October. During this period, the general trend of rainstorm all over the country is weakened. However, September is still one of the months with more tropical cyclones in the South China Sea and the Western Pacific, with an average of 5.3 tropical cyclones, second only to August; There are 1.8 tropical cyclones landing along the coast of China this month, which is the same as that in August. The rainstorm brought by tropical storm or typhoon has a great impact on the South China and southeast coast, and the precipitation intensity generally decreases rapidly from coast to inland. Flood geological disasters caused by high winds and rainstorms still need attention.

on the auspicious day of travel in 2020 began to affect the cold and high pressure in China. Under its control, the sinking and dry cold air first announced the end of the rainy season in Northeast, North and Northwest China, and took the lead in starting the best weather of the year. During the summer vacation, only the northeast and northwest regions really enter autumn. However, whenever the cold air affects our country, if the air is dry, it often brings windy weather. If there is warm moisture flow in the atmosphere, it often forms a decent autumn rain. After every storm, especially after rain, people will feel obvious cooling. Therefore, there is a folk saying: "an autumn rain (wind) and a cold". In the Jianghuai region in the south of the north, there may be a large precipitation process. The temperature drops obviously, the temperature difference between day and night increases, and the sun is in the sky after the rain. People often do not adapt to the changes in cold and heat at the turn of summer and autumn. If they are not careful, they are easy to cause respiratory tract, gastroenteritis, cold and other diseases. Therefore, it is said that "an eventful autumn".

Thunderstorm Activities: Thunderstorm Activities in South China, Southwest China and West China are not as active as in summer, but thunderstorm activities are still more in South China, Southwest China and West China. In South China, because the warm and humid air flow at low latitude is still relatively active, there are more thunderstorms than in other places; In southwest and West China, due to the edge of subtropical high and the effect of mountains, thunderstorms are also more active.

on the auspicious day of construction in 2020: in September in Western China, most of China began to enter a less rainy period, while there was more autumn rain in Western China. It is a special weather phenomenon in autumn in Western China. In addition to the Weishui and Hanshui River basins, autumn rain in Western China also includes autumn rain in Sichuan, most of Guizhou, Eastern Yunnan, Western Hunan and Western Hubei. Because of the early autumn rain, it can appear in late August. The earliest occurrence date can sometimes start in late August and end in late November at the latest. However, the main rainfall period occurs in September and October. The main feature of "autumn rain in West China" is that there are many rainy days, while another feature is that it is dominated by continuous drizzle. Therefore, although there are many rainy days, the rainfall is not very large, generally less than that in summer, and the intensity is also weak. Phenological characteristics of

: first, hawks are sacrificed to birds; Second, wait for heaven and earth to begin to disappear; Three Hou he naideng. In this solar term, eagles began to hunt a large number of birds; Everything in heaven and earth began to wither; "He naideng" refers to the general name of millet, millet, rice and sorghum crops, and "Deng" means mature. Eagles are sacrificial birds: Eagles began to hunt birds in large numbers. Heaven and earth began to disappear: everything between heaven and earth began to wither. He naideng: when the grain is ripe. The three seasons of the summer: This is what the three seasons of the summer say. On the day of the summer, the eagle is sacrificed to birds, the heaven and earth begin to be solemn on five days, and the Wo is ascended on five days. That is to say, every five days is a season, and the summer vacation time is from August 22 to 24 in the Gregorian calendar, so we can calculate the time of each of the three seasons by adding five days to this time.
