Why did the typhoon that made landfall in Fujian bring heavy rainfall to the Beijing Tianjin Hebei region?
Meteorological experts analyze that the heavy rainfall in the Beijing Tianjin Hebei region has a long duration and a large cumulative rainfall. Taking Beijing as an example, the intermittent heavy rainfall process will continue until the morning of August 2nd, and the duration may exceed 70 hours.
Why did Typhoon "Dussuri" bring heavy rainfall to the Beijing Tianjin Hebei region when it made landfall in Fujian thousands of miles away? According to Fang Chong, the chief forecaster of the Central Weather Observatory, on the one hand, the subtropical high pressure system in the eastern part of North China and the western high pressure belt have formed high pressure dams in the northern part of North China, which has slowed down the speed of Typhoon "Dussuri"'s circulation continuing northward and increased its duration.
On the other hand, because the typhoon "Dussuri" circulation itself carries a large amount of water vapor, and its east side is the subtropical high, the pressure gradient between the two will lead to a significant increase in the easterly and southeasterly winds in the Beijing Tianjin Hebei region, which will transport the water vapor near the typhoon "Kanu" in the western Pacific Ocean to the North China Plain from a long distance. At the same time, the water vapor is forced to rise due to the blocking of the Taihang Mountains in the west and the Yanshan Mountains in the north, which is conducive to the condensation of water vapor into rain. The combination of the above factors resulted in the heavy rainfall in the Beijing Tianjin Hebei region.
In addition, Typhoon Kanu, the 6th typhoon of this year, strengthened from a strong tropical storm to a typhoon on the afternoon of July 30th. It is expected that "Kanu" will move towards the northwest direction at a speed of about 20 kilometers per hour, turn to the northwest direction on the 31st, and move into the East China Sea during the day on August 1st, gradually approaching the coast of Zhejiang. Its intensity will continue to increase, with maximum intensity reaching strong typhoon or super typhoon levels. Under the influence of typhoon "Kanu", from August 1 to 4, there will be strong storms in the southeast sea area and coastal areas. There will be heavy to rainstorm in Jiangnan, eastern South China and other places, and local heavy rainstorm. In the next 10 days, there will be one more typhoon generated in the northwest Pacific Ocean.
Wang Xiurong, chief meteorological service expert of the Public Meteorological Service Center of the China Meteorological Administration, reminded that in rainstorm, people should try to avoid going out and staying in flood areas. This round of rainfall is a high-risk area for tourism. In the near future, it is advisable to avoid or reduce going out in these areas or visiting places that involve mountains and water.
