What are the high temperature weather recorded in history?

Meteorology, the weather with the highest daily temperature exceeding 35℃ is called high temperature weather. If the temperature stays above 35℃ for several days, this phenomenon is called "heat wave". The ancients called this extreme weather "heat disaster", which had a great influence on people's production and life. Because there were relatively few records of temperature in ancient China, the detailed description of temperature was mostly in the Ming and Qing Dynasties.

The earlier recorded heat wave disaster occurred in the Song Dynasty. It happened in the Southern Song Dynasty 12 15. The heat wave affects Henan, Jiangsu, Anhui, Hunan and other regions. The drought is severe, with flowers and trees withered and springs dried up in the affected areas. The consequence of excessive water shortage is that water is more expensive than oil. "One hundred pieces of water, dozens of pieces of a glass of water". Affected by the drought, working people have no crops and can't afford to drink water, resulting in people dying of thirst all over vilen.

The heat disaster in the Southern Song Dynasty was not the hottest time. According to the meteorological records of the Qing Dynasty, during the eight years of Qianlong, heat damage spread all over Beijing, Tianjin and Hebei, Shanxi and Shandong, and even pedestrians were killed by heat on the road. This hot summer disaster has also brought about a large-scale drought. In North China, there was no grain harvest and serious water shortage, and countless people died of thirst and heat. According to the current climate experts' estimation, the highest temperature at that time reached an astonishing 44.4℃, and it has never been so high until now.

According to historical statistics, there were 19 extreme hot seasons recorded in ancient China. Although there were no early warning measures such as weather forecast in ancient times, when high temperature weather appeared, the rulers generally adopted the strategy of reducing work and slowing down the people, warning the people to go out less and giving some compensation to the affected areas. Some rulers think that the hot weather is a warning from heaven, so they will do some actions to reduce meals and pray for blessings, and some even give amnesty to the world and pray for forgiveness from heaven.
