Why become the strongest this year? Latest news summary: heavy rainstorm | rainstorm | rainfall in Beijing lasts for nearly 50 hours
The rainfall process lasted for nearly 50 hours
Heavy rainstorm and extremely heavy rainstorm began to appear in Beijing on the night of July 29. As of 18:00 on the 31st, the rainfall process has lasted for 46 hours, with accumulated heavy rainfall and strong short-term rainfall. It is expected that there will still be significant rainfall from the night of July 31st to the morning of August 1st, especially in the western and northern regions where heavy rainfall will continue.
Meteorological department's analysis of Beijing's "strongest rainfall this year" →
The reporter learned from the meteorological department of Beijing that the reason why the heavy rainfall in Beijing is called "the strongest of this year" is because the heavy rainfall process is mainly influenced by the low-pressure system moving north after the weakening of Typhoon Dussuri's landfall and the warm and humid southward airflow around the periphery of the subtropical high. Especially, the strong southward airflow on the southwest side of the subtropical high continuously transports water vapor to the North China and Huanghuai regions, bringing large-scale heavy rainfall to this area, which belongs to a regional heavy rainfall process. At the same time, a high-pressure dam has formed in the northern part of North China, slowing down the northward movement of the low-pressure system and causing a longer stagnation time in the region, which is also one of the reasons for extreme precipitation.
As for why the rainfall in Fangshan and Mentougou areas is so high, the reporter learned that this is mainly due to the amplification effect of the terrain, which leads to the concentration of precipitation in the mountainous area, that is, the area with the highest rainfall along the Taihang Mountains. This rainfall process reached the magnitude of extremely heavy rainstorm, from eastern Xingtai, eastern Shijiazhuang to Baoding, and finally to Fangshan and Mentougou in the southwest of Beijing. When the low altitude wind direction is mainly southeast, the southeast wind rises under the influence of the terrain in the western mountainous areas, which greatly increases the precipitation. This is also a major reason for the more rainfall in the southwest of Beijing.
The Beijing Flood Control Office reminded citizens and tourists that there was still heavy rainfall in the western and northern areas of Beijing on the night of the 31st, with high overlap and extreme rainfall areas. Mountain areas and shallow mountain areas are prone to secondary disasters such as flash floods and landslides, and unnecessary travel is not necessary. At the same time, rainstorm prevention measures should be taken.

Deputy Commander of Beijing Flood Control and Drought Relief Command: The rainfall in Fangshan and Mentougou in Beijing far exceeds 7.21
Affected by typhoon "Dussuri", Beijing Tianjin Hebei and other places have been continuously hit by heavy rainfall since July 29. Seven rainstorm red warnings have been issued in three days, and the rainfall may last for 70 hours.

Last night, on the "News 1+1" program, Bai Yansong connected with Liu Bin, Deputy Commander of the Beijing Flood Control and Drought Relief Command and Deputy Director of the Emergency Management Bureau, to understand the intensity of this round of rainfall.
Bai Yansong: Based on the current overall data in Beijing, explain to what extent the rainfall has reached?
Liu Bin: We are currently facing a very difficult state. You may still have an impression of the "July 21" in rainstorm, when a day of heavy rain brought great disasters to Beijing. On the 31st, the average rainfall in the city also reached the level of 7.21 rainfall, especially in Fangshan District and Mentougou District, both exceeding 400 millimeters, which is much higher than 7.21 rainfall. To what extent? It is equivalent to a "7.21" rainstorm on the first day, and then another 160 mm and 180 mm on the second day. Mentougou District is 200 mm on the second day. In addition, the maximum point in Mentougou District is close to 700 millimeters, and Fangshan is close to 600 millimeters, which is also very high. At 7.21, the most memorable time for me was when the corrected precipitation in Hebei Town, Fangshan was 541 millimeters.
National Flood Control Administration: Floods and waterlogging disasters in Beijing may further intensify
On the evening of July 31, the National Defense General Office and the Emergency Management Department held intensive research and judgment meetings with the China Meteorological Administration and the Ministry of Water Resources. The video link was made to Beijing, Tianjin, Hebei and other key provinces to conduct rolling analysis and judgment on rainstorm and flood disasters in the Haihe River basin, and further arrange and deploy flood control and flood relief work in key areas. The reporter of the Beijing Daily learned that there were still rainstorm to heavy rainstorm in most areas of Beijing on the night of the 31st, and the flood disaster may be further aggravated.
Since the 29th, some areas in the three provinces and cities of Beijing, Tianjin, and Hebei have experienced extreme heavy rainfall. There have been large-scale floods in the Haihe River basin, and numbered floods have occurred in the Ziya River, Daqing River, and Yongding River. Flood storage and detention areas such as Ningjinbo, Dalu Ze, and Xiaoqing River have been put into use successively. Handan, Xingtai, Shijiazhuang, and Baoding in Hebei, as well as Fangshan and Mentougou in Beijing, have experienced severe flood geological disasters. After consultation, it is predicted that there will still be rainstorm to heavy rainstorm in most of Beijing, Tianjin, central and southern Hebei and northeastern Hebei this night, and the flood disaster may be further aggravated.
According to the National Flood Control Administration, we are entering the most critical stage of this extreme rainfall process. We must carry forward the spirit of unity, unity, fearlessness of difficulties, tenacious struggle, perseverance, and the courage to win in flood control and disaster relief, and spare no effort to do a good job in flood control and disaster relief. We must closely cooperate, unite and collaborate, implement a coordination and linkage mechanism in the Beijing Tianjin Hebei region, share and exchange monitoring and early warning information between upstream and downstream, left and right banks, and departments and industries, work together to fight disasters, and make every effort to do a good job in flood prevention and control in the Haihe River Basin.
We need to strengthen the scientific dispatch and emergency response, enhance the monitoring of rainfall and water conditions, accurately analyze flood trends, and finely dispatch flood control projects such as reservoirs, diversion and storage areas, and water gate hubs in accordance with the instructions of the National Flood Control Administration and the Haihe River Flood Control Administration. We will fully leverage the "storage, detention, diversion, and discharge" functions of the flood control engineering system and minimize flood disasters as much as possible. We need to strengthen inspections and fully defend ourselves, further implement flood prevention responsibilities, increase our inspection and rescue efforts, and achieve early detection and disposal of hidden dangers and dangerous situations to ensure flood prevention safety. To ensure safe transfer and maintain stability, strengthen publicity and mobilization, and do a good job in public work, according to the plan for the use of flood storage and detention areas, responsible persons, transfer routes, transportation vehicles, and resettlement locations must be implemented on a household by person basis. The transfer must be completed within the specified time, and the livelihood and safety management of the affected population must be properly ensured.
