China News Service, Beijing, August 16 (Reporter Chen Su) On the 16th, the Central Meteorological Observatory continued to issue a high-temperature red warning. As of now, the Central Meteorological Observatory has issued a high-temperature warning for 27 consecutive days, of which the highest-level red warning has been issued for 5 consecutive days.
This summer, China has experienced the "extremely long standby" heat. Since the fall, the high temperature weather has further escalated. How long will the high temperature weather last?
On August 11, in Beijing, under the scorching sun, tourists in Beihai Park have their own strategies for shading and sun protection.
On the same day, Beijing was sunny and hot, and the ultraviolet radiation was strong. The highest temperature in the afternoon climbed to 32 degrees Celsius, which was full of enthusiasm.

Since mid to late July, southern China has experienced continuous extreme high temperature weather.
As of the 16th, the number of high temperature days above 35 degrees in Shanghai has reached 43 days this year, and the number of consecutive high temperature days in Hangzhou since July 20 has reached 28 days, breaking the longest continuous high temperature record of 6 days.
In addition, the number of high temperature attendance days in Nanchang, Fuzhou, Changsha, Nanjing, Wuhan, Hefei and other places has reached more than 15 days.
At the same time as the "extremely long standby", this year's sweltering heat is extremely extreme, and more and more cities are joining the ranks of "stoves".
On the last day of Zhongfu (August 14), the temperature of a total of 70 national stations in Sichuan, Shaanxi, Chongqing, Hubei, Anhui, Jiangsu, Zhejiang and other places reached or exceeded historical extremes.
Among them, Chongqing can be regarded as the "hot leader" in the entire south. This summer, the local records (average temperature record, minimum temperature record, continuous 40°C + day record) were refreshed in all directions. On the 15th, the lowest temperature at Shapingba Station in Chongqing reached 33.8°C. Set a new record for the lowest temperature in the region.
On August 15, Wuhan, Hubei Province, a large area of tidal flats on the Hankou River Beach emerged from the water.
Affected by the significantly less rainfall in the Yangtze River Basin, the reduction of upstream water, and the increase in evaporation caused by the continuous high temperature, the water level in the Wuhan section of the Yangtze River continued to decline after the main flood season, and the phenomenon of "reverse dryness during the flood season" occurred.

According to the statistics of China Weather Network, in the recent national high temperature list, 40 ℃ is not uncommon, and 43 ℃ does not even make it into the top ten of the list.
Where did such long-lasting, large-scale, high-intensity high-temperature weather come from?
Meteorological experts told China News Agency reporters that the atmospheric circulation situation, especially the abnormality of the subtropical high in the western Pacific, is the main reason.
Chen Tao, chief forecaster of the Central Meteorological Observatory, said that from the monitoring point of view, this year's western Pacific subtropical high has a larger scope and stronger intensity.
Under its control, the entire southern region of China is controlled by downdraft airflow, and the sky is clear and less cloudy.
Under the influence of solar radiation during the day, the heating near the ground is intense, and the hot air stays on the ground, which cannot be blown away or dissipated, so a wide range of persistent high temperature weather occurs.
"Not only China, but also in the northern hemisphere this summer, the western Pacific subtropical high, the Atlantic subtropical high and the Iranian high have strengthened in stages, forming a large-scale overall global warm high pressure belt, and forming high temperature weather in many places throughout the northern hemisphere." Chen Tao said.
On August 12, in Nanjing, Jiangsu, children play in the water at the fountain on the street and enjoy the coolness.
On the same day, the Nanjing Meteorological Observatory continued to issue a red warning signal for high temperature.

Chen Lijuan, chief forecaster of the National Climate Center, said that according to the monitoring and later forecast of the National Climate Center, the rare high-temperature weather in China since June this year may reach the strongest high-temperature event since complete meteorological records were available in 1961.
Under the background of climate change, high temperature and heat wave events will become the norm, and high temperature and heat waves like this year may occur more frequently in future summers
With the passage of time, the temperature in various places continues to set records.
In the face of the "extremely long standby" heat, many Chinese netizens said that they have been "hot".
How long will it be hot in the future?
When can it cool down?
According to the forecast, the high temperature will not go offline for at least a week or two, and even the high temperature range may further expand.

According to Chen Tao, under the strong control of the subtropical high, the large-scale high temperature weather in the southern region will continue in the next one to two weeks.
Among them, around August 18, the high temperature weather may ease slightly, but this is only a temporary respite, and the high temperature will continue to develop and strengthen after that.
Specifically, in the next 10 days, there will be continuous high temperature weather in Jianghuai, Jianghan, Jiangnan, Sichuan Basin and southern Shaanxi, and the cumulative number of high temperature days can reach 6 to 10 days; High temperature weather will occur in the south, northern Jiangsu and Anhui; the highest temperature in the above-mentioned areas can reach 35-38 °C, and the local temperature can exceed 40 °C.
Experts remind that the extremely hot weather in southern China will continue for a period of time, and people in relevant areas must take measures to prevent heatstroke and cool down, avoid traveling during the high temperature in the afternoon, and beware of heat stroke or even heat stroke.
In addition, due to the continuous high temperature and heat and less rainfall, the drought situation along the Yangtze River will further develop, and attention should be paid to preventing adverse effects on agricultural production.
