Shanghai starts the II -level typhoon emergency response, and the "chasing team" detects the impact of urban buildings on the typhoon wind field

Facing the strongest 10 gust of gusts, a small drone flew into the air difficultly and detected the surrounding wind farm environment with a meteorological observation instrument; The unmanned land detector of the "Meteorological Dog" is also "sniffing" the wind and rain on the ground.

Since this afternoon, in the Lujiazui area of ​​Pudong New District, the "Chasing Team" of the Asia -Pacific Typhoon Research Center of the Shanghai Meteorological Administration is facing the typhoon "fireworks" directly in the wind and heavy rain to conduct high -precision typhoon wind field observation experiments.

Track the "plum blossom" mobile trajectory and detect the impact of urban buildings on the typhoon wind field

According to the data released by the Shanghai Central Meteorological Observatory, Typhoon Plum No. 12 this year has landed on the coast of Putuo, Zhoushan, Zhejiang, Zhejiang, Zhejiang. This is the first typhoon to land on the coast of East China this year, and it is likely to be the strongest typhoon to land this year.

The data collection work was officially launched in the afternoon. It is planned to continue the typhoon "Plum Blossom" mobile trajectory until the 15th night to examine the impact of the core area of ​​the high -rise urban agglomeration on the typhoon wind field. "The impact of urban architecture on wind will have great. Therefore, this time it will be combined with the characteristics of urban high -rise buildings and unique climate effects to pay attention to the impact of urban architecture on the typhoon wind field." Said Tang Jie, the person in charge of the research center.

According to reports, the operation was jointly carried out by the research center with the Shanghai Meteorological Information and Technical Support Center, the Pudong New District Meteorological Bureau, and the Baoshan District Meteorological Bureau. Zone, Lujiazui is the core area. It has been deployed in Huinan, Century Park and Lujiazui Meteorological Station to establish a gradient continuous observation mode. The equipment of the "Chasing the Wind" includes: 3 laser radar, 1 windline radar, small drone, ground detector and other high -tech monitoring equipment, and assist in exploring the observation methods of the Baoshan Meteorological Bureau.

Improve the typhoon emergency response to the level II basis

After the data released by the Shanghai Center Meteorological Observatory, "Plum Blossoms" will continue to move northwest at a speed of 20 kilometers per hour after landing on Zhoushan, Zhejiang. Although not big, "plum blossoms" also had a significant impact on Shanghai. The Shanghai Central Meteorological Observatory raised the typhoon warning signal to an orange level today. According to predictions, affected by the typhoon "plum blossom" on the body, the cumulative rainfall of this city can reach heavy rains and local heavy rainstorms tonight;

As of press time, the staff of the municipal meteorological department still adhered to the front line, paying close attention to the every move of "plum blossoms". He has released the "Important Meteorological Information Market Leadership Special", rolling the "Meteorological Disaster Early Warning Service Express" and typhoon dynamics to provide meteorological support for the large city flood control platform in Shanghai. Among them, the meteorological departments of Minhang, Jiading, Jinshan and other districts analyzed and judged the influence of "plum blossoms" in the next step of "plum blossoms" through video, on -site meetings.

In terms of the long triangle linkage, the meteorological departments of various localities maintain close communication through video discussions and telephones; in terms of remote sensing monitoring, the municipal ecological weather and satellite remote sensing centers are used to provide typhoon monitoring and analysis opinions and make typhoon remote sensing monitoring special reports. The resolution of maritime monitoring advantages will provide support for support for the two -level meteorological department of the urban area; in terms of public meteorological services, the Municipal Meteorological Service Center invites meteorological experts The municipal climate center combined with the risk threshold of the storm of facility greenhouse, drawing risk -level landing maps, and jointly issued a facility agricultural greenhouse wind disaster risk warning to the majority of farmers.

In addition, the Shanghai Flood Control Headquarters has launched the city's flood prevention platform II response operation. As of 8:30 tonight, a total of 189,000 people in the city had conducted inspections and inspections, and the inspection point was 135,000. Among them, 7,173 kilometers of Haitang embankment were inspected, 4114 construction sites under construction, 10123 residential communities, 11,255 underground spaces, 815 places, 63,000 stores, and 3,999 glass curtain wall buildings. 389,000 people have been transferred. The ship has entered 1,778 ships and 739 ships have been evacuated. Reinforcement of 20,000 trees, 1311 billboards, and 2964 shops and shops. Cancel the railway passenger 58 columns, cancel 71 long -distance road passenger transportation, the airport port has been shut down 50 times, the airport flight is canceled 589 times, and 32 flights of ship flights are canceled. There are 62 scenic spots in the city, and 13 parks are closed.
