How hot is this summer?

There are 71 national meteorological stations that break through the extreme value of history

Since June 13, my country has emerged for the first regional high -temperature weather this year. It has continued to experience high temperature and heat in many places.

As of July 12, the high -temperature incident has continued for 30 days, covering the land area of ​​5.021 million square kilometers in my country, affecting the population of more than 900 million people. The national average high temperature day reached 5.3 days, 2.4 days more than the same period of the same year, the most history since 1961. Among them, most of the high temperature days in East China, most of the Central China, the northeast of the southwestern region and the southwest of Shaanxi, south of Shanxi, and southern Xinjiang are 5 days to 10 days. The high temperature days in northwestern Jiangsu, northern Anhui, most of Henan, northwestern Hubei, southeast Shaanxi, and northeast Chongqing are more than 10 days older than usual.

Since June, a total of 238 national meteorological stations in Hebei, Henan, Tianjin, Tianjin, Yunnan, Sichuan, Zhejiang, Xinjiang and other places have exceeded the monthly extreme value, and a total of 71 national meteorological stations have exceeded the historical extreme value. Among the top ten sites at high temperature, Hebei Lingshou (44.2 ° C, June 25), Tancheng (44.1 ° C, June 25), Zhengding (44.0 ° C, June 25) and Yunnan Yanjin (44.0) ℃, July 11) The maximum temperature of the day exceeded 44 ℃. Lanzhou (37.6 ° C, June 24), Ningxia Yinchuan (37.2 ° C, June 16), Tianjin (40.1 ° C, June 25) and other provincial capitals or municipalities in the provincial capital or municipality break through the monthly extreme value. Shanghai Xujiahui Station not only appeared on July 10, the earliest 40 ° C high temperature day since the meteorological record, but also at 14:30 on July 13th, reaching 40.9 ° C. The highest temperature record.

June 25 is the day since June, the most high -temperature pole stations, of which the highest temperature of 28 stations exceeded the historical pole value, and the top ten sites in the daily highest temperature appeared in Hebei.

According to the regional high -temperature process monitoring indicators, the scope, strength and duration of high temperature events are comprehensively considered. The comprehensive intensity of the incident is the 6th since 1961, second only to 2013, 2017, 2003, 1966, and 2019 Essence Since 2000, the typical year of a large -scale high -temperature event in my country is 2003, 2013, 2017, etc. Generally speaking, this year's high temperature incident starts earlier than the above three years. The duration and historical high temperature polar value stations are not as good as these three years before. 2003 and 2013.

Early warning data can also see the degree of high temperature "explosion". Since June (as of July 13), in addition to Heilongjiang and Liaoning, 29 provinces (autonomous regions, municipalities) across the country have issued a total of 1,5008 high -temperature warnings, including 1869 red warnings, 8931 orange warnings, and yellow warnings. 4122, 86 blue warnings. Among them, the most high -temperature warning issued on July 10 was 857. Henan, Hunan, Shaanxi, Hebei, and Sichuan are the provinces with the most high -temperature warnings. The top ten provinces that have been released for the longest time are Henan (31 days), Xinjiang (20 days), Anhui (19 days), Shaanxi (17 days), Sichuan (17 days), Shanxi (13 days), and,, 13 days),, 13 days),, 13 days),, 13 days),, 13 days (13 days),,, 13 days),, Gansu (13 days), Hebei (12 days), Jiangsu (12 days), Yunnan (12 days), Shanghai, Shandong, Jiangxi and other places have continuously released high -temperature warning for more than 10 days.

From June 1st to July 13th, the top five provinces of high temperature warnings.

The northern hemisphere encountered "heat waves"

Extreme high temperature is attacking the world in many places

Extremely high -temperature weather is continuing globally, and the high -temperature heat wave incident spreads in Europe, East Asia, and North America, and the highest temperature breaks through the historical value at the same time.

In mid -June, Europe generally encountered high temperature heat waves. 6月10日，葡萄牙开始出现炎热天气；13日，西班牙中部和南部地区气温已经突破40℃；18日，法国出现此轮高温天气过程的最高峰，多达70个省份发布高温警报，多个The local high temperature records were broken; on the 19th, a record high -temperature weather in Germany appeared, and a forest fire broke out in Brandenburg, and about 620 residents were forced to evacuate.

In mid -June, the high temperature of the record spread from the Great Plains to the Mississippi Valley and the southeast. More than 125 million people in the central and most east of the United States are under high -temperature alerts, surpassing one -third of the US population.

On the afternoon of June 25, the temperature in Isezaki, Gunma Prefecture, Japan reached 40.2 ° C. It was the highest temperature in June since Japan's meteorological records. The global average temperature of the world in June 2022/"Global Disaster Weather Monitoring Monthly"

Why is the high temperature very strong?

Global warming and atmospheric circulation abnormalities are the main cause

The sixth evaluation report of the Special Committee for Climate Change of the United Nations (IPCC) pointed out that global warming in the past 50 years has occurred at unprecedented speeds in the past 2000, and the unstable climate system has intensified. UN Secretary -General Antonio Gutres call it "the red alert of all mankind". Global warming is a frequent climatic background in the high -temperature heat wave event in the northern hemisphere. The abnormal atmospheric circulation is the direct reason for frequent high -temperature heat waves in the world since June this year.

Since June this year, over the subtropical regions of the northern hemisphere, the Western Pacific subtropical high -pressure band, the Atlantic high -pressure belt, and the high -pressure average of Iran have enhanced, thereby forming a large -scale global heating high -pressure belt. Under the control of warm and high voltage bands, the prevalence of sinking air is conducive to the heating of the ground. In addition, under the action of a large -scale high -voltage belt, the air is dry and the cloud is not easy to form. , And strong intensity, which causes high temperature heat waves in the northern hemisphere.

Specifically, in my country, the continuous La Nina incident has provided an important climate background condition for the development of high temperature in the south since June of this year. Especially in July, the development of heating and high pressure bands in the middle latitude was strengthened, resulting in large -scale high temperature weather. According to statistical analysis, in the summer of most La Nina incidents, the Western Pacific subtropical high -pressure (referred to as auxiliary high) was easy to north. Since late June this year, the deputy high north, especially the typhoon "Siaba" in early July, has strengthened the west extension, Iran's high pressure east, and combined with the high pressure of the mid -latitude continent to form stability over my country. The heating high pressure zone, which causes a large range of high temperature weather. In addition, due to the water vapor carried by the vice -high high, the humidity of the central and eastern regions of my country makes the human body feel higher.

Compared with previous years, since July of this year, Iran has strengthened the high -voltage high -voltage high -pressure and mid -latitude high -voltage of the Western Pacific High -pressure and Mid -latitude, which has become a huge warm high -voltage belt, which is relatively rare in history. Historically, most of the high -temperature heat waves caused by Jiangnan, South China, Sichuan -Chongqing and other places due to the strengthening of the vice -high high, or the high temperature in the Northwest, Xinjiang and other places due to the stability of the mainland's high pressure. Therefore, this year, the high temperature range is relatively large, the duration is long, and the extremes are more prominent.

From June 1st to July 12

High temperature will continue

Do not take it lightly for production and life healthy protection

The National Climate Center estimates that from July 27th to August 11th, the temperature in most parts of my country is higher than the same period of the same year. Long -temperature weather process.

High -temperature weather has a great impact on power supply, people's production and life, and physical health. The public should try to avoid outdoor activities during high temperature hours, and work time should be shortened when operations under high temperature conditions. We must be particularly alert to fever, early prevention, early identification, and early treatment, especially the old, weak, sick, and young people should do a good job of heatstroke and cooling. Pay attention to the safety of electricity in high temperature weather. The power department should respond to deployment early to prevent supply shortages and fire hazards caused by the surge in electricity consumption and excessive power load.
