So far this year's high temperature comprehensive intensity is the third strongest since 1961

As of now, the average number of high temperatures in the country this year is 8.7 days, which is 3.6 days more than the same period of the year, the same period since 1961. This year's high -temperature comprehensive intensity is the third strongest since 1961, second only to 2013 and 2017.

At the press conference held on the 3rd on the 3rd, Xiao Yan, deputy director of the National Climate Center, introduced that the average temperature in the country just passed in July was 23.2 ° C, which was 1 ° C higher than the same period of the year. High, the highest temperature in the country's meteorological stations in the country exceeded the historical pole value of July in July. In July, the average number of high temperatures in the country was 5.6 days, which was 2 days more than the same period of the same year, which was the second most in history since 1961. East, Central China, Central China, East China and South China, and southwestern Xinjiang, high temperature days are 5 to 10 days higher than the same period of the year, and some areas are more than 10 days.

Xiao Yan said that high temperature is a common high -affecting weather in summer. Since entering the 21st century, the summer high temperature heat waves in the northern hemisphere have become increasingly frequent. Global warming is a frequent climate background of high temperature heat waves, while the atmospheric circulation is abnormal. The direct cause of the atmospheric circulation is the direct cause.

After the summer, the northern hemisphere subtropical high -pressure overall is stronger than the same period of the same year. The Western Pacific subtropical high -pressure band, the Atlantic high -voltage belt, and Iran's high -voltage average enhancement, a large -scale global heating high -pressure zone was formed over the subtropical region of the northern hemisphere. Under the control of warm high pressure bands, the prevalence of sinking air is conducive to the ground temperature, coupled As a result, there are continuous high -temperature heat waves in the northern hemisphere.

In addition, the average national precipitation in July was 96.6 mm, which was 20.6%less than the same period of the same year. It was the second in the same period since 1961. Tibet, Sichuan, and Yunnan were the least in history. Influenced by temperature and high rain, moderate and above in the eastern and southern parts of the southwest, east, central and central China, and part of East China.

It is expected that in August, the temperature in most areas across the country is close to the same period of the year. Among them, most of the East China, the most Central China, the northeast of the southwest, the majority of the Qinghai -Tibet Plateau, and the northern part of Xinjiang are 1 ° C to 2 ° C. Most of the northeast and the east of Inner Mongolia are low.
