  According to the forecast of the Central Meteorological Observatory, the large-scale persistent high temperature weather in southern my country will generally show a easing trend in the next week, with the scope and intensity of high temperature weather shrinking.

On August 23, the Central Meteorological Observatory continued to issue a high temperature red warning.

The Central Meteorological Observatory has issued high temperature warnings for more than 30 consecutive days since late July, and high temperature red warnings have been issued for 12 consecutive days since August 12.

In response to the recent high temperature weather and development, the reporter invited meteorological experts to explain in detail.

High temperature began to exit, Jianghan Jianghuai took the lead to ease

  According to the forecast of the Central Meteorological Observatory, from August 24th, the high temperature in Huanghuai, Jianghuai, Jianghan and other places will be basically relieved; from the 26th, the high temperature range in the Sichuan Basin and Jiangnan will be reduced, the intensity will weaken, and some areas will be relieved.

  According to Chen Tao, the changes in high temperature weather are affected by various factors. On the one hand, the cold air in the north will generally become active in the next three or four days, which will be beneficial to alleviate the high temperature in the southern region; on the other hand, this year's No. 9 typhoon "Masa" will be The landing on the coast of my country, the cloud system around the typhoon and the scattered precipitation also play a role in alleviating the high temperature in southern Jiangnan.

  Although the subtropical high, the main weather system that will cause high temperature in the next three or four days, has narrowed its scope and weakened its intensity, it still controls the Sichuan Basin to the middle and lower reaches of the Yangtze River. Under the influence of cold air and northward typhoons, the changes in the weather situation are still relatively complicated.

"Although the high temperature weather in the southern region shows an overall trend of easing, it will not end immediately or turn into a cool state. The large-scale high temperature weather has lasted for so long, and it will take a process to ease or relieve it, and there will be no sudden turning point." Chen Tao explained There are obvious differences in the time period and degree of high temperature relief in various regions. Among them, the high temperature in Jianghan and Jianghuai regions will be the first to be relieved from August 24; the high temperature in Zhejiang, Jiangxi, Hunan and other places will subside a little later. Japan and later; the high temperature relief period from eastern Sichuan to Chongqing will have to wait until after the 29th or even the 30th.

Typhoon "Masaan" landed in my country on the 25th

  At present, two typhoons are active on the western Pacific Ocean, namely the No. 9 typhoon "Masa" and the No. 10 typhoon "Scorpion Tiger" generated on August 22.

  In response to the influence of the typhoon "Masaan", Lv Xinyan introduced that the "Masaan" will move northwestward at a speed of about 25 kilometers per hour. After moving into the sea in the northeastern part of the South China Sea in the early morning of the 24th, it will gradually approach the coast of Guangdong, and its intensity will gradually increase. It made landfall along the coast from Shanwei to Dianbai in Guangdong during the day, and the intensity gradually weakened after landing.

  "Affected by it, there will be heavy torrential rains in western Guangdong and the coastal areas of Guangxi." Lv Xinyan said that this will have a certain mitigation effect on the high temperature in southern Fujian and eastern Guangdong, but after the typhoon "Saddle", the high temperature in the above areas may have There will be a rebound, but the overall situation in the later stage will not be as serious as the earlier stage.

  Typhoon "Scorpion Tiger" has also intensified into a severe tropical storm on the morning of the 23rd. In the future, "Scorpion Tiger" will have no impact on my country.

Record high temperature and significant meteorological drought Strengthen measures such as heatstroke prevention and cooling energy guarantee

  "This large-scale persistent high temperature weather in the south has a large range, a long duration, and a strong intensity, setting an extreme value since meteorological records began in 1961. It is a very rare high temperature and heat wave weather and climate event." Chen Tao said that the Central Meteorological Observatory In addition to continuous high temperature warnings, meteorological drought warnings have also been issued continuously.

  The record high temperature has affected people's production and life, agricultural production, energy security and many other aspects.

  According to Yuan Bin, as of August 22, the Public Meteorological Service Center of the China Meteorological Administration has released 56 high temperature and heatstroke weather forecast products in a row, and will continue to roll out the next seven days of high temperature and heatstroke weather forecast products.

In the future, the high temperature will generally ease, but the situation will vary from place to place. It is expected that from August 23 to 28, eastern Sichuan and some areas of Chongqing will continue to be extremely prone to heatstroke, and most of Jianghuai, Jianghan, and Jiangnan will continue to have high temperature and heatstroke. Reduced, weakened.

By the 28th, only northeastern Jiangxi and southwestern Zhejiang were prone to heat stroke.

  Yuan Bin suggested to continue to pay attention to the adverse effects of high temperature. People with weak constitutions, people with underlying diseases, outdoor workers, and indoor people without ventilation should take heatstroke prevention and cooling measures; the media, schools and communities carry out heatstroke and drowning measures. Relevant science popularization to further improve the awareness of risk prevention.

  Continued high temperature weather continues to increase the power load.

As of August 23, the power load meteorological condition index in Sichuan, Jiangsu, and Hubei provinces for nearly 60 days was significantly higher than the same period in history.

From the 24th, as the high temperature in the south gradually eases, the power load meteorological index of the provinces along the Yangtze River will also drop to the same level or slightly higher than the same period of the previous year, and the current situation of electricity shortage will be slightly eased.

However, the entire Yangtze River Basin is short of water, and the daily power generation of hydropower has declined.

  In addition, from July 22 to August 22, there were five forest fires in Fuling District, Jiangjin District, Zhiping Town, Nanchuan District, Bishan District, and Tongliang District of Chongqing City.

On August 22, after a comprehensive study and judgment by the Ministry of Emergency Management, the State Forestry and Grassland Administration, and the China Meteorological Administration, a red warning for high forest fire danger was jointly issued. The fire danger level will be extremely dangerous.
