Historical low temperature in Hubei

1. What is the lowest temperature in Xiaogan? Xiaogan History 1554 (thirty-three years of Ming Jiajing) Low temperature freezing injury is heavy snow in spring.

1566 (forty-five years of Ming Jiajing), heavy snow fell and many people froze to death. 1595 (twenty-third year of Wanli in Ming dynasty) March rain and snow, Vivi.

160 1 year (twenty-ninth year of Wanli in the Ming Dynasty), there was heavy snow in March, and there was no wheat. 1602 (thirty years of Ming Wanli) It snowed for several months in spring, and there was no wheat.

1629 (the second year of Chongzhen in the Ming Dynasty), the spring rain was covered with ice. 1650 (the seventh year of Qing Shunzhi), there was rain and ice in February.

Missing data from 165 1 to 1950. 195 1 After spring, it was cold and rainy, with 60% dead seedlings and 30% light seedlings.

1957 freezing injury in spring, broad beans freeze to death. From February 24th, 1960 to March 24th, 18, it was cold and rainy, in which a strong cold wave from March 13 to March 14 reduced the temperature by 15℃, and the lowest temperature was -0.8℃, accompanied by rain, snow and hail.

Of the 530,000 mu of wheat in the county, 10% was overwhelmed by snow, 78,000 mu of rape was overwhelmed by snow 50%, 80,000 mu of broad bean was overwhelmed by snow 22%, and 15 ~ 20% was overwhelmed by rotten early rice seedlings. Rainfall from April 1 day to April 12 day 12 day affects the growth of early rice seedlings and cotton seedlings.

1963 was cold and rainy from March to April, with light rain and snow in March 1 1, June 12, and April 7, and late frost appeared on April 9, resulting in a large reduction in rice and wheat production. 1February 8, 964 to 13 rainy season 125 hours and 29 minutes; 16 to 20, rainy season lasts 10 hour 12 minutes, extreme minimum temperature-10.0℃, extreme minimum temperature on the ground-13.4℃, which is harmful to posts and telecommunications and overwhelms 1046.

Some villages froze to death to raise cattle. It rained for 9 days from March 20th to 29th. 1965. The average temperature is 65438 00℃, the extreme minimum temperature is 4.2℃, and the seedlings suffer 50%.

It was cold and rainy for seven consecutive days in early April. 1966 From February 20 to 22, a heavy rainfall tide and strong wind process caused the temperature to drop 13.9℃, and the lowest temperature on the 23rd was -6. 1℃, accompanied by northerly winds of grade 5-6, which caused great damage to crops.

According to incomplete statistics, 40-50% of wheat, 60-70% of rape and more than 80% of broad beans were frozen to death, and cattle were also frozen to death. More than 300 poles were broken, 400 poles fell, and many wires were damaged. 1967 Rain and snow weather occurred from the end of February to the beginning of March, and the lowest temperature in the beginning of March was-1.6℃, causing freezing damage.

1October 28th to February 2nd 1969, lasting 125 hours and 38 minutes, the longest time since 1957. The telephone pole is broken, and the Fufu River and the main river are frozen. Low temperature and rainy days, from March 26th to April 4th, it rained for 9 days, with the average daily temperature below 65438 00℃ for 6 days and the lowest temperature of 65438 0.2℃. 197 1 rainy days in autumn, from September 6th to15th, there were eight rainy days and rains.

The freezing injury occurred in the spring of 1972. From March 20th to April 2nd, the temperature dropped by 65438 0.7℃, and the lowest temperature was 65438 0.4℃. On April 1 day and April 22, heavy snow fell, early rice seedlings were frozen, and barley, wheat, rape and broad beans were frozen.

It is rainy in autumn, and it rained twice on September 2 1-24 and June16-1October 2 1. Cotton rotten peaches make it impossible to sow in autumn. 1973 It rains continuously from April to May, especially in May. The rainy days last for 19 days, the rainfall is 220mm, and the temperature is lower than normal 1℃. During the meiyu period, the temperature is obviously low.

1From February 22 to 24, 974, a strong cold wave occurred, with the cooling range of 16.3℃, the lowest temperature of -6.7℃, and the instantaneous maximum wind speed of more than 8 (twice), accompanied by two days of intermittent rain and snow. The rainy season lasted for 40 hours and 28 minutes, and the leaves of rape in the county agricultural institute were frozen 100%, and the dead plants 10%.

1975 spring, cold and rainy. From April 15 to June 30th, the number of rainy days reached 5 1, and from April 15 to May 20th, it rained almost every day. Continuous rainy days, less sunshine and low temperature have caused slow growth of early rice and cotton, poor seedling quality and reduced production due to insect pests.

1976 It rained continuously in the spring, and the average temperature in April was lower than normal 1℃ (2℃ lower in the previous period), which was the lowest on record. From March 6 to April 29, there were five rainy days, the maturity of summer crops was delayed by 7 ~ 10 days, and the growth period of early rice and cotton was delayed by about one week.

On February 14, there was a strong cold front heading south, accompanied by strong wind and moderate rain, and the ground temperature reached 0℃. February 16, 9: 4 1 to 12: 24, it rained for 50 hours and 43 minutes continuously, which led to the obstruction of telecom communication. 1977 low-temperature freezing injury, 65438+1October 25th to 30th, was attacked by strong cold air in the north, the daily average temperature dropped from 2.4℃ to -7.6℃, and the minimum temperature dropped to-13. 1℃, accompanied by strong winds for six consecutive days.

1979 rainy season, 65438+ 10 month, 10 to 12, 28 to 30, two strong cold waves, with cooling ranges of 1 1℃ and/kloc-0 respectively. From June 28th 1980 to October 30th/kloc-0, affected by the strong cold air in the north, the three-day average temperature dropped by 1 1.8℃, and the minimum temperature dropped to -7.3℃, accompanied by freezing rain and snow, and crops suffered freezing damage in winter.

In spring, low temperature and freezing weather reappears. (1992 September edition of Xiaogan City Records).

2. When is the high temperature in Hubei from June to September every year? 1. The reason for the perennial high temperature in Hubei is that the high altitude in summer is controlled by the subtropical high belt; The second is the influence of topography.

1. In the Yangtze River valley at low altitude, the topography of the valley is like the bottom of a pot, surrounded by mountains, and the ground heat dissipation is difficult, which makes the temperature rise continuously; Thirdly, the rice field network is densely covered with water vapor and has high humidity, which makes it difficult for people to evaporate after sweating, greatly reducing the heat dissipation efficiency of sweating and making people feel stuffy under high temperature and high humidity. 2. Why does summer feel as hot as a stove? This song begins with the heat sensation of the human body. The main reason why people feel hot in summer is high temperature. The temperature of human skin is 32℃. If the temperature is higher than the skin temperature, people will feel hot. The higher the temperature, the longer the holding time and the more obvious the thermal sensation.

Summer in Hubei lasts more than 5 months every year, with an average of 60-70 days of high temperature, and the average number of days of high temperature above 35℃ is close to 18 days. Nevertheless, the highest temperature is not the only index to measure the heat in a place. For example, the highest temperatures in Beijing and Jinan reach 42℃, which is higher than that in Hubei, but it cannot be said that these places are hotter than Hubei. This is because what really makes people feel hot is related to humidity, wind and the lowest temperature in a day, in addition to the high temperature that is maintained for a long time or often appears.

Under the same high temperature weather conditions, if the wind is small, the humidity is high and the minimum temperature is high, the degree of heat that people feel will be aggravated. The high temperature period in summer is mainly from July to August, and the average temperature in Hubei is 28.6℃, while the temperatures in Chongqing and Nanjing, which are also known as the "three stoves" with Hubei, are lower than those in Hubei in July and August, which are 28.2℃ and 27.6℃ respectively.

From July to August, the relative humidity in Hubei was 79%, which was the highest among inland cities in China. If the lowest temperature in summer is above 27℃, people will feel very stuffy. The average number of days with the lowest temperature above 27℃ in July and August in Hubei is about 16 days, while in Chongqing and Nanjing it is only 8 days and 7 days.

What are the reasons for the high average temperature, high humidity, low wind and high minimum temperature in summer in Hubei? Hubei is located in the middle and lower reaches of the Yangtze River. In midsummer, the upper air in the middle and lower reaches of the Yangtze River is firmly controlled by the western Pacific subtropical high. The hot sun heats the earth, and the hot earth heats the air, causing the temperature to soar. Hubei and its surrounding waters are vast, with paddy fields and ditches everywhere. Under the scorching sun, water evaporates violently, which increases the air humidity. In addition, Hubei is flat and low-lying, with low altitude, which makes it difficult to dissipate heat, making the temperature change little during the day and at night, and the minimum temperature is high. Hubei is not only hot during the day, but also unbearable at night, just like a steamer, which is also the feature of hot weather in Hubei; In addition, the urban heat island effect in Hubei is also very obvious. With the development of urbanization in Hubei, the urban heat island effect is more obvious, which also increases the heat of the city in summer. In a word, the high temperature in summer in Hubei is closely related to atmospheric circulation, urban topography and urban heat island effect.

I also want to tell you the fact that the summer heat in Hubei has been further strengthened since the 1990s. Since 1990, the average number of high temperature days in summer in Hubei is 3 days more than that in normal years, and the number of days with the lowest temperature exceeding 27℃ is 7 days more than that in normal years, which means that the number of high temperature days in our city has increased in recent years. Second, suggestion: 1, give more subsidies for high temperature; 2. Go out as little as possible at high temperature to prevent heatstroke; 3. Get ready for health.

3. What is the lowest temperature in history? How many international research teams have set the lowest temperature record in human history? Source: Xinhuanet Xinhuanet Berlin, September 1 1 Sunday (Reporter Pan Zhi) An international research team composed of scientists from Germany, the United States, Austria and other countries recently rewrote the lowest temperature record created by human beings: they reached a temperature only 0.5 Kelvin higher than absolute zero in the laboratory. The previous record was 3 nanograms higher than absolute zero. This is the first time in human history that the extreme low temperature is above absolute zero and within 1 Nakel. Kelvin is the thermodynamic degree of day, referred to as "Kay" for short, 1 nanogram is equivalent to 1 degree Celsius, and 1 nanogram is equivalent to one billion kelvin. 0 Kelvin means that absolute zero is the limit of temperature, which is equivalent to MINUS 270 degrees. At this temperature, the molecules will stop moving. The research team published a paper in the new issue of American Science magazine, saying that they set this record in the process of realizing Bose-Einstein condensed state (BEC) of cesium atom by using magnetic trap technology. David prichard, a scientist who participated in the research, said that cooling the gas to extremely close to absolute zero is of great significance for accurate measurement. Their experimental results are helpful for making more accurate atomic clocks and measuring gravity more accurately. Bose-Einstein condensation is a peculiar state of matter, in which a large number of atoms behave like a single particle. The "condensation" here is different from the condensation in daily life, which means that atoms in different States suddenly "condense" into the same state. To realize this material state, on the one hand, it needs to reach a very low temperature. On the other hand, the atomic system is required to be in the gas state. Chinese physicist Zhu Zeng shared 1997 Nobel Prize in Physics with two other scientists for inventing laser cooling and magnetic trap refrigeration. Scientists say that they hope to discover new phenomena of some substances by using the newly reached lowest temperature. For example, the state of atoms on the surface of the same object at this low temperature, the state of motion when the area of motion channel is limited, and so on. Wolfgang kettler, a German scientist who won the 200 1 Nobel Prize in Physics for discovering the new state of matter "Bose-Einstein condensation of rare gases of alkali metal atoms", commented that it was a milestone in human history to reach the temperature above absolute zero for the first time.

4. The historical low temperature in Wuhan is the historical record of several degrees in that year. The lowest temperature on February 29th was -9.6℃, 199 1.

The lowest temperature recorded in Wuhan since the 20th century (21116) is -7.8℃, followed by 20 13+05-7.2℃.

2065438+65438 2006+-19.4℃ broke the historical record and refreshed the extreme low temperature since the 20th century. In addition, it is not common for the temperature in Wuhan to drop below minus 8℃. 199365438+1October 16 -8℃,191+February 29th -9.6℃. Calculated -9.4℃ is also the lowest temperature in Wuhan after 24 years.

5. What is the highest temperature in Wuhan? The highest historical temperature in Wuhan should be above 40 degrees.

Compared with last year, there are not many hot days in Wuhan this summer. Although there were two waves of heat waves and autumn tiger attacks, they didn't last long. After July 1 1, the first heat wave hit the middle and lower reaches of the Yangtze River, and Wuhan was hot for several days. On 13, the highest temperature in Wuhan first appeared at 38℃, and reached 39℃ on 14, and the lowest temperature on that day also exceeded 30℃. On June 6, 65438, the lowest temperature in Wuhan reached 3 1.6℃, setting a record for the lowest temperature in Wuhan since June 1907. According to Zhang Xuezhi, a senior engineer of Wuhan Meteorological Observatory, it is not uncommon to see continuous high temperature in Wuhan in summer, but it is rare for the lowest temperature to exceed 30℃.

Due to the hot weather, East Lake, indoor swimming pool, water park and riverside are all crowded, and people have jumped into the water to seek coolness. According to the person in charge of a swimming pool, the museum receives thousands of people every day these days. Nan 'anzui has also become a good place for citizens this year. According to reports, every night from 6 pm to 8 pm, the South Bank is crowded, and sometimes people are reluctant to leave until three or four in the morning.

According to experts, from the end of July to the beginning of August, the subtropical high controlled the Yangtze River basin, and a second heat wave appeared in Wuhan. During this period, the highest temperature in the blinds of Dongxihu Lake was 36.7℃, which was not as "compelling" as the first high temperature, but it also made the public feel stuffy.

In late August, subtropical high and continental high alternately "sit in the village", and "autumn tiger" appeared in Wuhan. On the 24th, the temperature in the louver was 36.4℃, and the high temperature came back again, which has continued to this day.
