Can typhoons affect Beijing？ Beijing Meteorological Bureau： Seven times in history.
BEIJING, Beijing, July 25 (Xinhua) From 20: 00 on the 23rd, due to the influence of Typhoon Abe, there was rain and heavy rain in Beijing. In this regard, many netizens questioned why Beijing, located in North China, can also be affected by typhoons. In this regard, the Beijing Meteorological Bureau said that since the meteorological record, there have been seven times when the typhoon weakened and the low pressure passed through or approached Beijing.
"Typhoon storm" strikes Tianjin and Hebei, and typhoon warning is issued for the first time.
According to the news from the meteorological department, the Beijing Meteorological Observatory upgraded and issued a yellow rainstorm warning at 9: 00 today (25th). Hebei Province and Tianjin Meteorological Observatory issued typhoon blue warning signals on the afternoon of the 23rd. This is the first time that Tianjin and Hebei have issued typhoon warning information since China Meteorological Bureau officially implemented the Measures for the Issuance and Dissemination of Meteorological Disaster Warning Signals in 2007.
According to the monitoring of the Central Meteorological Observatory, the center of Typhoon Abe No.10 is located in Tianjin Dagang at 08: 00 on July 24, with a tropical storm level, the maximum wind force near the center is 8, and the center pressure is 990 hectopascals, and it will move north-east at a speed of 20 kilometers per hour.
According to the Beijing Meteorological Bureau, the rainfall is characterized by long duration, relatively gentle rainfall and uneven rainfall distribution.
Specifically, there is moderate to heavy rain in Beijing during the day, and there are heavy rains in front of the mountain and in the eastern and southern regions. The heavy rainfall period will last until around 14: 00, and the precipitation process is accompanied by weak lightning, with gusts of about 7 in the eastern region; There were thunderstorms on the night of the 24th. The maximum hourly rainfall intensity is 20 ~ 40mm.
Why can "Abe" affect Beijing? Forecast: It will also affect the Northeast.
Many netizens have questions, why is Beijing, located in North China, also affected by typhoons?
According to the Beijing Meteorological Bureau, there are two reasons why typhoon Abe can continue to move northward with tropical storm intensity: first, the route after landing is close to the coastline, which makes half of Abe’s structure stay at sea and half on land. The continuous water vapor and good environment on the ocean help it maintain a relatively complete "shape";
Second, the terrain is relatively flat. Most areas in Jiangsu and Shandong are dominated by plains and hills, with gentle slopes and small fluctuations, which have little effect on weakening the intensity of typhoons.
In addition, the Central Meteorological Observatory predicts that Abe will interact with cold air in the future, and will also affect Liaoning, Jilin, Heilongjiang and other places, bringing heavy rainfall to many places in Northeast China.
Historically, Beijing has been affected by typhoons seven times.
According to the news of Beijing Meteorological Bureau, there have been seven times when the low pressure after the typhoon weakened passed through or approached Beijing since the meteorological record was recorded. The details are as follows:

On August 6th, 2005, Typhoon No.9 "Mai Sha" made landfall in Yuhuan County, Zhejiang Province. From the night of August 8 to the day of August 9, it affected Beijing. Due to the influence of the weakened low-pressure western marginal cloud system, moderate to heavy rain occurred, and Shunyi had the largest rainfall, reaching 76 mm. Because the typhoon center is relatively eastward, the rainfall in the city is relatively gentle and lasts for a long time.
7. On July 29th, 2017, Typhoon Haitang No.10 landed in Fuqing City, Fujian Province. On August 2nd, there was moderate to heavy rain in Beijing from day to night due to the joint influence of weakened low-pressure trough and eastward-moving high-altitude trough, with heavy rain in some areas and heavy rain in Fangshan, Daxing, Pinggu, Miyun and Shunyi.
