The first time was from 1 100 BC to 850 BC, that is, the first cold period in the early Western Zhou Dynasty, and there were almost no relevant historical materials. The earliest records did not directly say snow, but "rain and hail", which was found in the chronicle of bamboo books. This happened in the seventh year of Wang Xiao in the Western Zhou Dynasty. "In winter, heavy rain and hail killed cattle and horses, and the rivers and rivers froze." At that time, some cattle and horses were wild and froze to death because of their strong frost resistance, which showed the fierceness of heavy snow.
The second time was: from the early years of AD to AD 600, equivalent to the late Western Han Dynasty to the early years of Sui Dynasty, during which it experienced the Eastern Han Dynasty, the Three Kingdoms, the Jin Dynasty and the Southern and Northern Dynasties. In fact, before this, climate anomalies have appeared, and droughts and floods have continued. When Liu Che (Emperor Wu of the Han Dynasty) was emperor, there was heavy snow in winter for several years. Records of Five Elements in Hanshu recorded the major snowstorm in the Western Han Dynasty. "In December of the first year of the founding of Liang Wudi, heavy rain and heavy snow froze many people to death. In March of the second year in Ding Yuan, it snowed and the ground was five feet thick. Three years in Ding Yuan, water ice in March, rain and snow in April, people in more than ten counties in Kanto eat each other. In November of the second year of Zhao Jian, Yuan Di, the snow was as deep as five feet. " Many ordinary people froze to death, and the snow was five feet thick. According to the unit conversion of the Han Dynasty, now one foot is about 22 cm, and five feet will reach 1 10 cm, which shows the large amount of snow. As the old saying goes, people are seven feet tall, and the heavy snow almost reached the chest of the ancients.
The third time: during the Tang, Song and Yuan Dynasties, there was a super heavy snow at the end of the Tang Dynasty, and even the people in the palace froze to death every day. The year of Ye Li (Tang Zhaozong), the penultimate emperor of the Tang Dynasty (AD 90 1), was a troubled year. First, it rained for a long time at the turn of summer and autumn. It began to snow after winter, and even the sleet didn't stop until spring, which is what the history books said: "It snowed from winter to spring rain." On such a bad snowy day, even the food in the palace was cut off, so Ye had to order the imperial secretary to build a small mill in the palace to grind beans and wheat to satisfy his hunger. "Since the 16th Palace of the harem, the deceased died on March 4th." In the imperial palace, three or four people freeze to death and starve to death every day, and the depth of civil disasters can be imagined.
The records of snowstorms in the history of the Five Elements in the Song Dynasty are the most in the early Northern Song Dynasty. During the 22-year reign of Song Taizong Zhao Guangyi, the second emperor of the Northern Song Dynasty, snowstorms occurred in five years. There are many records about the snowstorm in Song Dynasty, and countless animals and plants froze to death. "History of the Song Dynasty, Five Elements" "In November of the first year of Tianxi, heavy snow and cold in Beijing killed many people. There were zombies on the road and they were sent to the suburbs to be buried. In the first month of the following year, there was a heavy snow in Yongzhou, which lasted for six days and nights. Fish in rivers and streams froze to death. In November of Zheng He's third year, it rained heavily for more than ten days, and the ground was more than eight feet high. The ice is slippery, but horses can't. I ordered the officials to enter the DPRK in a sedan chair. Many birds died. " Zheng He snowed for more than ten days in November of three years, killing many birds. Snow is eight feet deep, so you can imagine how terrible it is. People jump in and disappear instantly. At that time, the soldiers standing guard in the capital were too cold to carry weapons, and some soldiers were frozen into zombies. "The people didn't eat or burn, so the government had to let the people go to the imperial garden to cut flowers and trees for firewood.
The fourth cold period was in the Ming and Qing Dynasties, with many days of snowfall, cold weather and frightening depth of snow. According to the historical records of China Meteorological Disaster Ceremony, there were records of snow "Changyu" in Jiangxi, Zhejiang, southern Anhui and southern Jiangsu during the Ming and Qing Dynasties. One foot is ten feet. The standard of feet in Ming and Qing dynasties was different, about 0.32-0.35 meters, which is not much different from today's one foot and 33 centimeters, and is about the height of a 2-liter beverage bottle. "Zhang Yu" is about 3.3 meters, which is equivalent to the height of 10 2-liter beverage bottles, and the height is estimated to be similar to that of rural bungalows. In the winter of the fourth year of Jingtai in Zhu Qiyu (Emperor Taizong of Ming Dynasty) (A.D. 1453), rare heavy snow fell from north to south in China, and the weather was extremely cold. It snowed for more than a month in Hebei, Shandong, Jiangsu, Zhejiang and Guangxi, and the disaster was serious: Suzhou, Jiangsu and Taihu Lake were suspended, the ports froze, and people and animals froze to death; Anji, Zhejiang, "freezing to death 100 people"; Cangzhou, Hebei, "there are countless people and animals frozen to death"; Dezhou, Shandong Province, "People and animals freeze to death". Zhu Houzhao was emperor in Zhengde for eight years (A.D. 15 13). The heaviest snow fell in East China, rivers froze, birds and animals froze to death, and even villagers froze to death. Taihu Lake, Dongting Lake, Poyang Lake and other southern great lakes have become "super skating rinks" at the same time: Taihu Lake is "frozen, and pedestrians walk on the ice for more than ten days"; Dongting Lake is "ice and snow, it is feasible for people to ride". In the winter of the ninth year of Kangxi (AD 1670), there were 40 to 60 days of continuous heavy snow in North China, East China and Central China. The section from the Yellow River to Longmen freezes, and the Huaihe River freezes for two months. In the local chronicles of many provinces and cities in China, there are records of freezing to death.
The nearest thing to us is the catastrophic snowstorm in 2008. A massive snowstorm. From Harbin, Yichun, Jiamusi, Siping, Songyuan, Shenyang, Anshan, Benxi, Huludao and Jinzhou in the three northeastern provinces, to Kulun, Tongliao and Kezuohouqi in Inner Mongolia, and then to Jinan in Shandong. Snow covered less than half of China. The average snowfall and amount of snow in Shenyang have completely exceeded the snowstorm in the Lantern Festival in 2007, with an average snow cover of about 40 cm, making it the largest snowstorm in Liaoning since the meteorological record. 1October 9 165438, the deepest record since the snow depth in Tongliao, Inner Mongolia was broken 195 1. In the Horqin area of Tongliao, due to the deep snow, local residents basically rely on "crawling" to travel, and the wind is as high as eight or nine, which is dazzling. Many people should still remember the snowstorm in 2008. Freezing rain was the chief culprit that caused the disaster that year. When it rains, it is supercooled water below 0℃. When it touches branches, wires, hay and other ground objects, it will freeze into a smooth and transparent ice shell. It was the low temperature and freezing rain that caused the interruption of power supply, Hunan section of Beijing-Guangzhou railway and Hunan section of Beijing-Zhuhai highway, which seriously affected the transportation in Spring Festival travel rush in that year.
