War High Temperature Data
Yesterday, the Municipal Government Information Office held a special press conference on the city's high temperature and drought relief work in 2022 to introduce the city's high temperature and drought relief work this year.
The highest temperature in 9 districts and counties broke the local historical high temperature record
Since July, the temperature in Chongqing has been significantly higher and the precipitation has been significantly lower. The highest temperature in 9 districts and counties has broken the local historical high temperature record, and the accumulated rainfall has been 60% lower than the same period of the previous year, especially since August. .
Zou Yu, member of the Party Committee and Director of the Political Department of the Chongqing Emergency Management Bureau, introduced that since July 1, the weather in Chongqing has mainly shown "three significant" characteristics:
First, the average temperature is significantly higher.
The city's average temperature was 30.5°C, 2.6°C higher than normal, and tied with 2006 as the highest since 1961.
The second is significantly less precipitation.
The city's average precipitation was 102.0 mm, nearly 60% less than normal, the second lowest since 1961 and second only to 98.8 mm in 1992.
Third, the intensity of high temperature and drought was significantly stronger.
The number of high temperature days above 35°C was 32.3 days, the third most in the same period since 1961, second only to the same period in 2006 (33.9 days), and the extreme maximum temperature of 44.5°C was the same as in 2006.
According to monitoring, 67.9% of the cultivated layer of soil moisture observation stations has reached moderate to severe drought.
Affected by the high temperature weather, 881,000 people in 33 districts and counties, 585 townships (streets) in the city have been affected, and 300,000 people need life assistance due to drought, of which 269,000 people have difficulty drinking water (mainly concentrated in alpine towns and towns and cities). remote areas); 66 rivers in 8 districts and counties stopped flowing, and 25 reservoirs in 10 districts and counties dried up; the water storage capacity of water conservancy projects in 26 districts and counties was less than 70%, among which Fengjie, Kaizhou, Pengshui, Wulong, Cheng The seven districts and counties of Kou, Wushan and Wuxi were lower than 50%.
"It is expected that the high temperature will continue for at least a week." Zou Yu said that the daily maximum temperature in most parts of the city will reach 38-42 ℃, and the local temperature will reach 43-45 ℃. There were 18 more days in the same period, exceeding the highest value for the same period since meteorological records began.
From August 30th to September 1st and from September 8th to 9th, there may be cooling and rainfall, and the high temperature weather in Chongqing is expected to gradually ease.
Mobilize 900,000 people to find and deliver water to solve the drinking water problem of the masses
In the face of severe high temperature weather, it is very important to do a good job of drought relief.
Zou Yu introduced that at present, the Municipal Flood Control and Drought Relief Headquarters is making every effort to make overall plans, daily research and judgment, supervision and guidance, water supply and drink protection, high temperature fire prevention, and material allocation "six measures" to actively respond to the current high temperature and drought conditions.
In terms of water supply and drinking, the city organized nearly 900,000 grass-roots cadres and masses to find water and supply water, and the problem of drinking water for the masses was guaranteed.
In terms of high temperature fire prevention, the municipal forest fire prevention and fire fighting headquarters issued a red warning of forest fire danger, held a scheduling meeting, and conducted special inspections.
In terms of material allocation, the city has dispatched 98,000 rescue teams, 270,000 rescue equipment and vehicles, allocated 180 sets of large-scale drought-resistant water storage equipment, and allocated 10 million yuan of drought-relief funds. The problem of drinking water difficulties in districts and counties has been basically solved.
Artificial precipitation will be carried out in a timely manner once there is an opportunity for operation
In response to the artificial precipitation enhancement operations that citizens are generally concerned about, Zou Yu said that at present, 266 weather-affected operation sites, 107 anti-aircraft artillery pieces, 96 rockets and nearly 600 operators have entered a state of war, closely monitoring the weather.
"As soon as there is an opportunity for operation, artificial rain enhancement and cooling operations will be carried out in a timely manner to alleviate the high temperature and drought."
The city will take no major wildfires as the bottom line, and do a good job in forest fire prevention.
To control the fire source and not enter the mountain, strictly set up the gate guard card; control the fire in agriculture and sacrifice, strengthen the patrol, check the smoke and punish the fire; especially focus on preventing the elderly and children from entering the mountains to use fire.
In addition, the city will take resolute prevention and control of major accidents as the core goal, strictly carry out "three investigations and three governance", and solidly carry out special operations for safety inspections and 100-day rectification.
Strictly investigate the performance of cadres, strictly investigate the law enforcement of departments, and strictly investigate the management of enterprises.

Why is the high temperature "extended"?
How long will it be hot?
...
Here are the answers to the "hot" questions you care about
Yesterday, the Municipal Government Information Office held a press conference on "The City's High Temperature and Drought Relief Work in 2022", and responded to these "hot" issues of public concern.
Why is the hot weather longer?
Yang Zhi, member of the party group and deputy director of the Municipal Meteorological Bureau, introduced that there are two main reasons for the high temperature this year:
First, the subtropical high over the western Pacific has been abnormally strong since July, the low trough of the westerly belt and the active position of cold air are located in the northerly area, and the subsidence airflow prevails in the entire Yangtze River Basin, resulting in sunny, hot and less rainy weather in the Yangtze River Basin including Chongqing.
Second, most of the cities and towns in Chongqing are located in the valleys with lower altitudes in the east of the Sichuan Basin, which is not conducive to the diffusion of surface heat. The continuous heat accumulation has led to rare persistent high temperature weather in most parts of the city.
How long will the heat last?
According to Yang Zhi, according to the latest meteorological data, it is expected that from mid to late August to early September, the city will still maintain the general trend of high temperature and low precipitation.
Specifically, from August 16th to 24th, the daily maximum temperature in most areas will reach 38-42°C, and locally it can reach 43-45°C.
Around the 25th, there was a weak rainfall process in the city, and the high temperature weakened.
From August 30th to September 1st and from September 8th to 9th, the city has a relatively obvious cooling and rainfall process, and the high temperature weather will gradually ease.
What should I pay attention to in summer vacation in the mountains?
Zou Yu, a member of the Party Committee and Director of the Political Department of the Municipal Emergency Management Bureau, reminded that when camping in the mountains to escape the heat or playing on the water, you should be especially vigilant against the mountain torrents caused by sudden changes in droughts and floods.
How to prevent?
The first is to "see": one is to see if the nearby weather has changed abruptly during the game, and the other is to see whether the water level of the stream is rising rapidly, and whether the water flow suddenly becomes turbid. If you see these two situations, you should be highly vigilant.
The second is "listening": if there is an abnormal mountain humming near the ravine, or a train-like roar, you must be on high alert.
When the public encounters flash floods, the most effective measure is to run.
Run quickly without hesitation, and evacuate to the higher-lying areas on both sides of the river.
When camping in the wild, it is necessary to choose a flat high ground as the camp, and try to avoid the hillsides or valleys and ditch bottoms with rolling stones, rock collapses or a lot of accumulations.

my country's regional high temperature
Strongest on record in 1961
According to the monitoring and evaluation of the National Climate Center, comprehensively considering the average intensity, influence range and duration, the comprehensive intensity of regional high temperature events since June 13 this year has reached the strongest since the complete meteorological observation records began in 1961.
The range above 40°C is the largest in history
According to reports, this process has the characteristics of long duration, wide range, high intensity and strong extreme.
As of August 15, the high temperature event has lasted for 64 days, the longest duration since 1961 (more than 62 days in 2013); 1680 weather stations were covered above 35°C, and 1426 weather stations were covered above 37°C. Both are the second largest in history (second only to 2017, with 1762 stations and 1443 stations respectively), but the coverage area above 40°C is the largest in history.
From June 1 to August 15, the national average number of high temperature days was 12.0 days, 5.1 days more than the same period of normal years, the most in the same period in history since complete meteorological observation records began in 1961.
The number of high temperature days in southern North China, most of East China, eastern South China, northeastern Southwest China, and most of Xinjiang is generally more than 20 days, and more than 30 days in central and eastern Xinjiang, eastern Sichuan, and Chongqing.
A total of 914 national meteorological stations across the country (accounting for 37.7% of the total number of stations in the country) reached the daily maximum temperature of extreme high temperature events.
The daily maximum temperature of 262 national meteorological stations in Hebei, Qinghai and other places remained the same or exceeded the historical extreme.
The daily maximum temperature in Hubei Zhushan (44.6°C) and Chongqing Beibei (44.5°C) reached 44°C and above.
The duration of this regional high temperature event will continue to be extended, and the comprehensive intensity will be further enhanced.
According to the Ministry of Emergency Management, at present, the water levels of the main stream of the Yangtze River, Dongting Lake, and Poyang Lake are 4.5-6 meters lower than the same period of the previous year, which are the lowest in the same period since the actual measurement record.
The reporter learned from the Flood Control and Drought Relief Department of the Ministry of Emergency Management that as of 3 p.m. on the 16th, the affected area of crops in 6 provinces and cities in the Yangtze River basin, including Sichuan, Chongqing, Hubei, Hunan, Jiangxi, and Anhui, was 17.64 million mu.
High temperatures will be frequent in the following summer
Yuan Jiashuang, deputy director of the National Climate Center, said: "With the intensification of climate warming in the future, extreme high temperature and heavy precipitation events will occur frequently and repeatedly in the future. Factors such as precipitation, sea level rise, storm surges, etc., will also increase the probability of complex flood events, and humans will face greater climate risks and impacts.”
Chen Lijuan, chief forecaster of the National Climate Center, said in an interview with the media that the duration, intensity and scope of this summer's high-temperature heat wave have reached a very strong level, and there are deep climate-scale reasons behind it.
We have to face a reality: similar high temperatures and heat will occur frequently in the following summers.
At present, the influence of global greenhouse gases is very strong. In the context of global warming, high temperature and heat wave events will become a new normal.
