Beijing, August 2 After experiencing a rare July "empty station", as soon as August entered, there were two typhoons one after another. In the past few days, some provinces along the southeast coast have raised their emergency response levels and deployed wind and flood protection. Meteorological experts predict that although there were fewer typhoons in August this year than usual, more typhoons landed in China, which should be taken seriously.

Typhoon is coming again, "Senrak" is not gone, "Hagupit" is coming again

  After "empty stations" in July, the typhoon became active just as August entered. Typhoons No. 3 and No. 4 followed. The Central Meteorological Observatory issued a blue typhoon warning at 18:00 on August 1.

  At 14:00 on August 1, 2020 Typhoon No. 3 "Senrak" was generated. The Central Meteorological Observatory predicts that "Senrak" will land on the coast of northern Vietnam on the afternoon of the 2nd, and the intensity will gradually weaken. The arrival of "Senrak" has brought violent storms to coastal areas. The Central Meteorological Observatory predicts that there will be heavy rains in parts of southern Hainan Island, southwest Guangxi, southern Guangdong and other places from 20:00 on August 1 to 20:00 on August 2. Heavy rain (100-150 mm).

  The National Marine Forecast Station continued to issue blue waves and storm surge warnings at 16:00 on the 1st. It is expected that from the night of August 1st to the daytime of August 2nd, there will be large waves of 3 to 4.5 meters to the huge waves in the South China Sea and Beibu Gulf; medium to large waves of 2 to 3 meters will appear in the coastal waters of western Guangdong, eastern Hainan and southern coast. The wave warning level in coastal waters is blue.

  Typhoon No. 3 was formed less than 12 hours ago. Typhoon No. 4 "Hagupit" (English name: Hagupit; name source: Philippines; name meaning: whip) generated again on the evening of the 1st, with its center in Zhejiang at 8 o'clock in the evening. On the ocean surface about 950 kilometers southeast of Cangnan, 21.3 degrees north latitude, 126.9 degrees east longitude, level 8 (18 m/s).

  The Central Meteorological Observatory predicts that "Hagupit" will move to the northwest at a speed of about 15 kilometers per hour, gradually increasing in intensity, and approaching the coast of Zhejiang and Fujian. It will land on the coast from central Zhejiang to northern Fujian on the night of the 3rd (tropical Storm level, level 8, 18-20 m/s).

  Hu Xiao, chief meteorological analyst of China Weather Network, analyzed that typhoons "Hagupit" and "Senrak" are close to each other, and there is a certain impact between the two. The future development of "Hagupit" is uncertain and may There will be a significant increase in the process, and then gradually weaken offshore.

Typhoon is about to rain, heavy waves and high waves deployed in various places to deal with typhoons

  Although Typhoon No. 3 only passed from Sanya, Hainan, and Typhoon No. 4 has not landed in China for the time being, the strong winds and rains they brought have already affected some areas. For this, various localities have taken corresponding measures to defend against.

  On August 1, the State Office of Defense and the Ministry of Emergency Management held a flood prevention and typhoon conference and discussion meeting, requesting that ships return to ports to avoid wind, offshore operators and offshore aquaculture personnel should go ashore to avoid danger, timely transfer of people, and resolutely avoid personnel casualties. It is necessary to strengthen the investigation of hidden dangers, and do a good job in the prevention of mountain torrents and geological disasters, prevention of floods in small and medium rivers, and urban drainage and waterlogging.

  Affected by "Senrak", Hainan has experienced heavy rains and even torrential rains in recent days, and it will also rain in general in the next three days. On the afternoon of August 1, Hainan Province held a video conference on the province’s defense against Typhoon No. 3 "Senrak", requiring close tracking of typhoon monitoring and timely warning and forecasting; precautionary measures should be taken to investigate reservoirs, construction sites, and flood bridges in advance At the same time, make preparations for power safety, urban drainage, etc., and pay attention to wind protection in tourist attractions to ensure the safety of tourists.

  At 15:30 on August 1st, the Guangdong Provincial Flood Control, Drought, and Wind Prevention Headquarters Office and Guangdong Provincial Emergency Management Department also launched a fourth-level emergency response for flood control while maintaining a fourth-level emergency response for flood control to respond to "Senrak". The continuous wind and rain impacts that will be brought to Guangdong.

  As Typhoon No. 4 may land along the coast of Zhejiang and Fujian, the Fujian Meteorological Bureau predicts that from the night of the 2nd to the morning of the 4th, there will be 8-9 gusts of magnitude 10 to 12 in the waters of the Diaoyu Islands, Mindong Fishing Ground and Minwai Fishing Ground, 3.5 ~ 5 meters big to huge waves. Fujian Province decided to start the Typhoon Type IV emergency response at 18:00 on August 1.

Typhoons will come together in August, or 3 typhoons may land in China

  In August, the typhoon started a "relay race". Does this mean that the typhoon's active period has arrived?

  According to the forecast of the National Climate Center, the number of typhoons generated in the Northwest Pacific and South China Sea in August this year is 4-6, slightly less than that of the same period in normal years; the number of typhoons that landed in China is 2 to 3, which is slightly lower than the same period of normal years. many.

  Looking at the situation in previous years, in August, the average number of typhoons landed in China was about 1.9. China's coastal provinces (cities, districts) except Hebei and Tianjin, from Guangxi to Liaoning, have been the land of typhoons in August. It can be said that August is the month with the widest impact of typhoon landing.

  Statistics from the China Meteorological Administration show that from 1949 to 2019, a total of 403 typhoons were generated in the Northwest Pacific and the South China Sea in August. On average, nearly 6 typhoons were generated in August each year, with an average of 1 every 5 days. A typhoon is generated.

  Meteorological experts analyzed that the average intensity of the August typhoon was not too top-notch, but it does not mean that there was no super typhoon in August. For example, the No. 12 typhoon "Wanda" landed in Zhejiang with a super typhoon intensity in 1956, so we still need time. Stay alert.
