"High fever without fever" Yunnan Yanjin led the national experts at 44 ° C yesterday: The frequency and intensity of high temperature heat waves increased

Although Sanfu Tian has not arrived, the "baking roast" model has been opened in advance in many places in the country. The high temperature of 40 ° C in multiple cities has "standby". The highest temperature in Lingshou County, Hebei Province has even exceeded 44 ° C. On July 11, China Weather Network data showed that the highest temperature in the city appeared in Yanjin in Yunnan that day, ranking first in the country at 44 ° C, and Sichuan Lianlian ranked second in the country with 42 ° C.

According to the information published by the Central Meteorological Observatory, since July 6, a total of 18 provinces (autonomous regions, municipalities) have appeared above 35 ° C, which are mainly distributed in the southern Xinjiang Basin, central and western Inner Mongolia, Gansu, northeast Qinghai, Ningxia, and Ningxia,,, Ningxia,,, Ningxia,,, Ningxia,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,, Ningxia,,,,,,, Shaanxi, central Shanxi, Tianjin, central south of Hebei, Henan, Shandong, Sichuan, western Hubei, Anhui, Jiangsu, Zhejiang, Shanghai, and northern Fujian. Among them, the highest temperature in the Sichuan Basin, the Guanzhong Plain of Shaanxi, and other localities exceeded 40 ° C.

Zhu Dingzhen, chief expert of the Meteorological Service Center of the China Meteorological Administration's Public Meteorological Service Center, said in an interview with the reporter of "Daily Economic News" that combined with the current climatic characteristics of my country's season, high -temperature weather in some areas is normal, but some places have a record of breaking records in some places. High temperature is not normal.

The maximum temperature breakthrough in Shaanxi, Sichuan and other places at the same time of history at the same time

In fact, since mid -June this year, a large -scale high -temperature weather process has appeared in my country.

On July 8th, at the routine briefing meeting of the State Council held by the Flood Control and Disaster Rescue Work held by the National New Office, Wang Yawei, the head of the Emergency Disaster Reduction and Public Service Department of the China Meteorological Administration, said that the average temperature in my country in June was 21.3 ° C, which was 0.9 higher than the same period of the same year. ℃, the highest history since 1961. Among them, Henan, Shaanxi, Gansu, Ningxia, Shanxi, Shandong, Jiangsu, and Anhui all have the highest temperature in June in June.

Fu Jiaolan, the chief forecaster of the Central Meteorological Observatory and the senior engineer of Zhengyan, said that since July 6, a total of 18 provinces (autonomous regions, cities) have appeared above 35 ° C. Among them, the highest temperatures in parts of 10 areas including Ningxia, central and western Gansu, central and western Inner Mongolia, central and southern Shaanxi, southern Hebei, western Henan, Sichuan Basin, central Zhejiang, Shanghai, and southern Jiangsu, the highest temperatures have even reached 37 ° C to 39 ° C to 39 ° C The highest temperature of the Sichuan Basin, the Guanzhong Plain in Shaanxi, the Hanzhong Plain, the Ankang Basin and other localities exceeded 40 ° C.

Fu Jiaolan said that the highest temperature in Gansu, Ningxia, Northeast Qinghai, south of Shaanxi, Sichuan Basin and other places has broken or reached the extreme value of the same period.

"Daily Economic News" reporter passed the central meteorological platform's official website inquiry. At 20:00 on July 10, data from 2418 national meteorological observation stations showed that the temperature ranked in the top ten in the country was Turfan, Xinjiang, Ankang, Shaanxi, and Chongqing, respectively. Shapingba, Sichuan Hejiang, Sichuan Wusheng, Xinjiang Tocoke, Zhejiang Tongxiang, Chongqing Rongchang, Zhejiang Yiwu and Sichuan Gaoxian.

Taking Shaanxi Ankang as an example, compared with historical climate data from July 3 to 10, 2021, compared with the same period last year, the lowest temperature is not much different, but the maximum temperature is significantly higher than last year. For example, the highest temperature on July 9, 2022 was 40 degrees, but the highest temperature in the same period last year was only 33 degrees.

Continuous high temperature weather appears in the subtropical high -pressure control area

Why does high temperature weather continue? In an interview with the reporter of "Daily Economic News", Zhu Dingzhen said that in general, in June and July in my country, the northern part of the central region was controlled by the high pressure of the mainland. After July, especially after the end of the southern plum rain season, high temperature and hot weather will appear. That is the so -called subtropical high -pressure control.

Zhu Dingzhen further stated: "Before the Typhoon 3 Siaba 'came, the subtropical high -pressure south, high -temperature weather appeared in the north of the mainland.' Siaba 'came north from the west side of the subtropical high pressure. After that, the mainland high -voltage and subtropical high -voltage have been opened. That is, the limits of the subtropical high pressure came up, the limit reached about 25 degrees, and the West Point also passed 110 degrees, and it was promoted westward. "

"If there is an image to see, we can find that there are continuous high -temperature weather in the area where the subtropical high -pressure control is controlled. If the subtropical high pressure continues to stabilize, the high temperature will continue." Zhu Dingzhen said.

Fang Xiang, deputy director of the National Meteorological Center, said that most of the northern parts of my country are controlled by a strong heating high -pressure system, which prevails to sink the air. Dry, the ground during the day is affected by the solar radiation, and the temperature rises quickly. The stable and maintenance of this circulation has led to continuous high temperature weather in the northern region. In addition, the westwest airflow also sinks in the east foot of Taihang, and it also plays an important role in extreme high temperature weather in Hebei, Henan and other places.

So, how will the high temperature trend develop in the future? Is most parts of our country still a "site" with a subtropical high pressure?

In this regard, Fu Jiaolan analyzed that from July 9th to 10th, there were still high temperature weather in the southern Xinjiang Basin, western Inner Mongolia, central and southern Shaanxi, southern North China, and Huanghuai. After the 11th, Iran's high pressure was significantly weakened, and a heavy precipitation process will occur in the northern region of my country, which can alleviate the impact of this round of high temperature on the north.

Fu Jiaolan further stated that in the next 10 days, the subtropical high pressure will be further extended to the north to control most of the southern parts of China. The high temperature weather in the south will develop further. In hot weather, the temperature of the Sichuan Basin, Zhejiang and other places can reach above 40 ° C. The frequency of high -temperature heat waves has increased?

The Central Meteorological Observatory continued to issue high -temperature yellow warning at 18:00 on July 10: It is expected to be during the day on July 11, the northwest of Inner Mongolia, the Turpan area of ​​Xinjiang and the eastern part of the southern Xinjiang Basin, the south of Shaanxi, the south of the Huanghuai There are high temperatures above 35 ° C in Jiangnan, central and northern parts of South China.

Among them, Turpan, Xinjiang, southern Shaanxi, central Anhui, southern Jiangsu, most Shanghai, eastern Hubei and northwest, most Hunan, most Jiangxi, Zhejiang, central and northern Fujian, central and eastern Sichuan Basin, Chongqing, northeast of Guizhou The highest temperature in some areas in northeast Yunnan and other areas of 37 ~ 39 ° C, the Turpan area of ​​Xinjiang, the plain areas in south of Shaanxi, central Zhejiang, central Fujian, southeast of Sichuan Basin, western Chongqing and northern parts can reach 40 ° C.

"Daily Economic News" reporter noticed that since this year, my country's heavy rains and high temperatures have frequently alternated, and extreme climate occurred from time to time. For example, since the flood in the flood, there are many heavy rain in the southern my country, and the local disaster has a heavy impact. According to the data of the China Meteorological Administration, from from the flood to May 31, a total of 11 cold air affects my country, including the cold wave process 5 times.

At the same time, it has ushered in high temperatures recently, which makes people unbearable. According to the China Meteorological Administration, from June 13th to 26th, the process of regional high temperature weather in the central and southern parts of North China, Huanghuai, Jianghuai, Jianghan and other places in China appeared. It affects the population of more than 600 million people.

In recent years, why have extreme climates frequently occurred? What impact will extreme weather bring? Zhu Dingzhen said that the high temperature of continuous high -intensity breaking records, or the continuous heavy rainfall is an extreme climate. "From the current research situation, the frequency and intensity of high -temperature heat waves have increased."

Jia Xiaolong, deputy director of the National Climate Center, has clearly stated that global warming has exacerbated the unstable climate system, which is the root cause of frequent and intensity of extreme weather events. With the warming of the climate, the atmosphere can accommodate more water vapor before saturation, and the possibility of extreme heavy precipitation increases.

Zhu Dingzhen told reporters: "The water content in the atmosphere of high temperature will increase, or the ability of water content can be increased. Therefore, in the case of high temperature, once rainfall occurs, the rainfall is greater and the duration is longer." The frequency of rainfall or rainstorm may increase, because it has higher water content than air with low temperature.

"Daily Economic News" reporter noticed that the Central Meteorological Observatory continued to issue a high -temperature orange warning at 18:00 on July 11: It is expected to be during the day on July 12, the southern Xinjiang Basin, south of Shaanxi, southern Huanghuai, eastern southwestern region, Jianghan, Jianghuai , Jiangnan, South China and other places have high temperatures above 35 ° C. Among them, Anhui, southern Jiangsu, Shanghai, western and southeast of Hubei, northern Hunan, Jiangxi, Zhejiang, Fujian, southeast of Sichuan Basin, Chongqing, Guizhou, Guizhou The highest temperatures in some areas in the northeast are 37-39 ° C. The southern parts of Jiangsu, northern Shanghai, southern Zhejiang, southeast of Sichuan Basin, central and western Chongqing and northern parts can reach 40 ° C.

At the same time, the Central Meteorological Observatory also issued a yellow warning of heavy rain at 18:00 on July 11: It is expected to be 20:00 on July 11th to 20:00 on July 11th, southeast of Gansu, central Shaanxi and southwestern Shaanxi, southern Shanxi, central Hebei, Tianjin, Tianjin There are heavy rains in parts of the south, central and northern Shandong, northern Henan, and northwestern Sichuan Basin. Among them, there are heavy rains (100 to 180 mm) in southeast of Gansu, southwestern Shaanxi, northern and east of Shandong. The above -mentioned areas are accompanied by short -term and heavy precipitation (the maximum hourly rainfall is 20-50 mm, and the local area can exceed 70 mm), and there are strong convective weather such as thunderstorms in the local area.
