China News Service, July 25. According to the website of the China Meteorological Administration, the Central Meteorological Observatory announced the typhoon landing news at 12:30 on July 25: The center of this year's No. 6 typhoon "Fireworks" has been at 12 noon today (25th) It landed on the coast of Putuo, Zhoushan, Zhejiang Province around 30 minutes. The maximum wind force near the center was 13 (38 m/s) at the time of landing, and the lowest air pressure in the center was 965 hPa.

  The "fireworks" are expected to pass through Hangzhou Bay and make landfall again this evening from Jiaxing, Zhejiang to Qidong, Jiangsu (typhoon level, level 12, 33-35 m/s).

  According to meteorological experts, the typhoon "Fireworks" has the characteristics of complicated path, wide range of influence, superimposed wind and rain tide, long duration on land after landing, and large accumulated rainfall.

  Multiple typhoons interact with each other and their paths are complicated.

This year’s No. 6 typhoon "Fireworks" was generated on the Northwest Pacific Ocean at 02:00 on July 18, and then the No. 7 typhoon "Chapaca" and No. 8 typhoon "Niya" were generated on the east and west sides of the "Fireworks". "Bert", the interaction of multiple typhoons and the influence of other weather systems have resulted in slow movement of the "fireworks", complex paths, and difficult forecasts.

  The typhoon is large and has a wide range of influence.

The “firework” cloud system is very wide, with a span of about 1,500 kilometers from east to west and a span of about 1,200 kilometers from north to south.

"Fireworks" yesterday (24th) has brought great wind and rain to Zhejiang, Shanghai, Southern Jiangsu and other places, and will continue to affect most of eastern China such as Zhejiang, Shanghai, Jiangxi, Jiangsu and Anhui in the later period.

  After landing, the land lasted for a long time and accumulated rainfall.

Although the intensity of the "fireworks" gradually weakened after landing, the accumulated rainfall in Zhejiang, Shanghai, Jiangsu, northeastern Jiangxi, and southern Anhui was large. The above-mentioned areas must guard against the effects of extreme rainfall caused by the "fireworks" and the weakened residual circulation.

  Three storms meet, and the impact is superimposed.

July 25th is during the astronomical tide. Before and after the "fireworks" landed in Zhejiang, Shanghai, Jiangsu and the coastal areas, three encounters of wind, rain and tide will occur, which will have a great superimposed influence.

  Typhoon "Fireworks" may stay for a long time after landing, bringing continuous heavy rainfall and windy weather to East China. At the same time, it is during the astronomical tide period. The three storms meet, and the public in Zhejiang, Shanghai, Jiangxi, Jiangsu, Anhui and other places need Prevent the occurrence of disasters such as urban and rural waterlogging, floods in small and medium rivers, and mountain torrents.

In addition, Shandong, Henan and other places also need to pay close attention to the future mobile trend and influence of "fireworks".
