At 23:20 on July 11, 2026, Typhoon Bavi (typhoon scale) landed in Yuhuan City, Taizhou, Zhejiang Province. Upon landfall, the maximum wind force near the typhoon center reached Grade 13 (40 m/s), and the minimum central air pressure was 955 hPa. Under the guidance of the Shanghai Typhoon Institute of China Meteorological Administration, Zhejiang Meteorological Service, Jiangsu Meteorological Service and the Shanghai Asia-Pacific Typhoon Research Center, ZOGLAB set up its typhoon-chasing service team and completed the preparation of mobile observation equipment within 7 hours. The team rushed to Taizhou, Zhoushan, Wenzhou, Suzhou, Nanjing and other areas to deploy three full-series MMEOS mobile meteorological emergency observation vehicles, portable weather stations, precision barometers, wind lidars and other equipment for multi-dimensional coordinated meteorological observation.

Typhoon-Chasing Record

Two Days Prior to Landfall

At 09:00 on July 9, we officially received the assignment for the coordinated observation campaign of Typhoon Bavi. ZOGLAB quickly broke down tasks, allocated staff and tested equipment to push forward all preparation work for the campaign without delay.

By 16:00 on July 9, all pre-campaign preparations were completed. Four teams with a total of nine staff members set off for observation sites in Taizhou, Zhoushan and Wenzhou.

One Day Prior to Landfall

At 12:00 on July 10, mobile observation equipment for three stations in Yuhuan of Taizhou and Dinghai of Zhoushan was fully deployed, and the mobile observation team in Cangnan of Wenzhou arrived at the site to launch multi-point coordinated observation simultaneously.

8 Hours Prior to Landfall

At 15:00 on July 11, based on data from coastal meteorological sites in Zhejiang, all coordinated observation campaign sites and the typhoon track forecast bulletin issued by the National Meteorological Center, it was determined that the predicted landfall location of Typhoon Bavi was gradually shifting northward. The mobile observation team from Wenzhou headed to Yuhuan of Taizhou for rendezvous. Meanwhile, equipment deployment at the newly added observation site in Nanjing, Jiangsu was completed.

Official Landfall

Around 23:20 on July 11, Typhoon Bavi made landfall at Kanmen, Yuhuan, Taizhou, Zhejiang. At landfall, the maximum wind force near the typhoon center reached Grade 13 (40 m/s, typhoon strength), with a minimum central pressure of 955 hPa. Mobile observation devices at all monitoring sites continuously recorded meteorological data throughout the typhoon landfall process.

Mobile Observation

Mobile observation equipment serves as the core devices ZOGLAB deployed for this joint typhoon observation campaign. Systems including the MMEOS Mobile Meteorological Emergency Observation System and HWS3000-SPS Super Portable Station feature outstanding mobility and portability, enabling rapid response to typhoon landfall observation missions.

The LWR2500 and LWR500 laser wind radars adopted in the test can supplement blind-area detection for large wind profilers and scanning radars under low cloud conditions, enriching the completeness of observational data.

Media Attention

 Typhoon Bavi intensified into a Super Typhoon merely 42 hours after its formation. Following a nearly 10-day long oceanic track, it made direct landfall in Zhejiang Province. Every stage of its evolution drew extensive attention from all sectors of society. ZOGLAB’s mobile observation equipment deployed on the frontline of Bavi’s landfall also received wide media coverage, serving as a vivid epitome of meteorological services for typhoon defense and disaster mitigation.
