Experts from the Central Meteorological Observatory analyzed why the high temperature continued to hit a large area.

　　According to the news of China Weather Network, since June 16th, the high temperature weather in China has exploded. Looking at the map of China, from Shaanxi and Henan in the north to Anhui and Shanghai in the middle, and then to Fujian and Guangdong in the south, at least 14 provinces, autonomous regions and municipalities are in high temperature. According to He Lifu, chief forecaster of the Central Meteorological Observatory, this is the largest range of high temperature weather in China this year, and the Central Meteorological Observatory also issued the first high temperature warning this year on the 17th.

He Lifu, chief forecaster of the Central Meteorological Observatory, was interviewed by Zhao Qian Photography on the 19th.

　　Large-scale, long-term and high-temperature continuous baking in China

　　Up to now, high temperature has been steaming China for three consecutive days, and at least 14 provinces, autonomous regions and municipalities including Shaanxi, Henan, Anhui, Jiangsu, Zhejiang, Shanghai, Hubei, Hunan, Jiangxi, Chongqing, Sichuan, Fujian, Guangxi, Guangdong, etc., all experienced high temperature weather exceeding 35℃.

　　"The hottest places are Chongqing, Henan and Hubei. The high temperature is 37 to 39 C, and the local temperature is over 40 C." He Lifu concluded that the high temperature in Chongqing has lasted for 4 days, which is a typical example of severe and lasting heat. Yesterday, the highest temperature in Chongqing was 41.4℃, a record high this year, making it the hottest day in the same period in June since 1962.

　　In response to the largest range of high temperature weather this year, the Central Meteorological Observatory issued a high temperature warning for three consecutive days on the 17th, and all localities also launched active responses. It is understood that the high temperature in Lian Qing has caused some students in Chongqing to have mild heatstroke symptoms. Some primary and secondary schools have taken high temperature leave since the 18 th and suspended classes in the afternoon; In Xi’ an, from the afternoon of the 17th, the cool air-raid shelter was opened free of charge. Wuhan Civil Affairs Bureau also launched 1460 community cool spots on the 18th …

　　Under the high temperature, netizens are also spitting out. Among them, a paragraph "A student of a university in Chongqing fell on the playground and was finally identified as a third-degree burn by the school hospital" was widely reprinted, and netizens responded that "Chongqing can be replaced by Nanjing, Changsha, Wuhan, Chengdu and other cities."

　　The culprit of heat: the subtropical high that attacked the inland

　　From mid-June to early July last year, it was the rainy season in the middle and lower reaches of the Yangtze River, with fewer days of high temperature. However, why did the high temperature continue to hit a large area in mid-June this year? He Lifu analyzed that this was affected by the subtropical high "stretching westward and jumping northward".

　　Subtropical high is the main weather system that affects mainland China in summer, and the areas it controls are prone to persistent sunny and hot weather. "At this time last year, the subtropical high was maintained in the south of the Yangtze River and South China, but the subtropical high went inland to the north and west two days ago, controlling Hubei, Henan and other places, leading to a wide range of high temperature weather recently." He Lifu said.

　　After 21 days, the subtropical high will return to the south of the Yangtze River and South China, and the high temperature range will be reduced to the south, and the high temperature weather in Shaanxi, Henan, Hubei, Jiangsu, Anhui and other places will gradually ease.

　　Jiangnan south China welcomes high temperature protracted war

　　The high temperature in the south will be maintained in the next few days, and the number of continuous high temperature days in big cities such as Chongqing, Changsha and Nanchang may break the record. Take Chongqing as an example, the high temperature has lasted for 4 days from 15th to 18th, and will continue until 23rd, and the number of consecutive high temperature days will reach 9 days, or it will break the record of 8 consecutive high temperature days since June 1961.

　　"This hot weather is just a warm-up, and Jiangnan and South China have not yet entered the real hot season." He Lifu said that throughout July and August, Jiangnan and South China will be controlled by the subtropical high, and more persistent and strong hot weather will be ushered in.

　　In this regard, He Lifu reminded that Jiangnan, South China and other places need to make preparations for enduring high temperatures, and relevant departments should pay attention to preventing fires caused by excessive electricity consumption and heavy loads on power equipment such as wires and transformers; It is best for the public to avoid going out at high temperature in the afternoon. Workers working outdoors or under high temperature conditions should take necessary protective measures, pay attention to work and rest time, ensure adequate sleep, and prepare some commonly used heatstroke prevention and cooling drugs when necessary.
