Ocean University of China successfully observes Typhoon Muifa with wave buoy system
On July 28, Typhoon "Muifa" formed on the sea surface of the Northwest Pacific Ocean and then rapidly strengthened to become the third super typhoon of the year. "Muifa", with its formidable strength, was nicknamed "Meichao Wind" by netizens. Questions about how powerful "Muifa" would be, what impacts it would have on the marine environment, and how we should respond, all require accurate forecasts of marine hydro-meteorological elements. However, forecasting cannot be done without prior on-site observations of the typhoon, which is where observation methods such as marine buoys come into play.
Pursuing typhoon observation is always the best opportunity to obtain first-hand data and is an important prerequisite for marine hydro-meteorological forecast analysis and disaster prevention and mitigation decision-making. On August 2, just before "Muifa" approached, the East China Sea Branch of the State Oceanic Administration issued a task to deploy and accept the inspection of the 3m multi-parameter wave buoy system independently developed by the Ocean University of China in the East China Sea area. Professor Tang Yuanguang, head of the Marine Instrument Equipment Research and Development Center of the Automation and Measurement Control Department of the Engineering College and leader of the project, immediately organized the members of the project team to rush to Shanghai. After shore-based system joint debugging, the buoy was successfully deployed in the designated area of the East China Sea before the approach of "Muifa" on August 5.
The buoy has a diameter of 3m and effectively solves the safety issues of wave buoys. In addition to measuring waves, it can also measure wind fields, air pressure, water temperature, air temperature and other parameters. It reserves interfaces for parameters such as ocean currents and water quality, expanding the measurement parameters of the buoy. It adopts solar power supply to extend the operation time of the buoy at sea and greatly improves the comprehensive performance of the buoy.
After withstanding the severe test of the stormy weather and harsh sea conditions during "Muifa's" passage through the East China Sea, the buoy system worked normally and observed the entire process of the typhoon passing by, receiving on-site data revealing the secrets of the typhoon and obtaining relatively complete data on the typhoon's passage. At the acceptance meeting of the "3m Multi-parameter Wave Buoy System" held on August 9 by the East China Sea Branch of the State Oceanic Administration, the experts present unanimously believed that "the implementation of this project has added new observation means to the wave observation of our country's marine stations."
The successful observation of Typhoon "Muifa" by the 3m multi-parameter wave buoy system and its subsequent acceptance are another successful example of the cooperative model of learning, production, and research at the Ocean University of China. From bidding and initiating projects according to national and social needs, to closely cooperating with the East China Sea Branch of the State Oceanic Administration and others for joint development and application, it fully demonstrates the strength of the Ocean University of China in the field of marine monitoring technology, enhances the university's R&D service capabilities in marine buoy observation systems, and forms a team capable of undertaking the R&D of large-scale marine monitoring equipment and technical support teams. This lays the foundation for taking on larger R&D tasks in the field of national marine monitoring in the future, expands influence, and broadens space.
