“Drifting Air-Sea Flux Buoy” Breakthrough in Measurement Application

[ China Instrument Network Instrument R&D ] The “Drifting Air-Sea Flux Buoy” independently researched and developed by the National Oceanic Technology Center has made important breakthroughs in the comprehensive offshore measurement and application of the Kuroshio Extension in the Northwest Pacific.

The National Marine Technology Center was established in 1965 and is part of the national ocean. The main functions and basic tasks of the center are the operational management of the state’s marine technology; the provision of technical support and technical support for the national marine planning, management, capacity building, and public service; and the marine high-tech and forward-looking, basic, and universal Research and development of technology.

The exchange and change of heat energy between the air-sea interface is an important factor affecting climate change. The air-sea interface observation plays an important supporting role in the research of climate change, upper oceans, atmospheric boundary layer structure, and atmospheric circulation. The buoy has the ability to collect and send deep-sea marine environmental data automatically and stably. It is an important means for the current air-sea interface observation, and is the basic technical equipment for long-term fixed-point monitoring of deep-sea marine environments.

It is reported that the buoy uses drifting networking to conduct high-precision, high-temporal-spatial-resolved scientific observations and real-time data transmission of air-sea interface meteorological and hydrological parameters, mainly collecting sea surface winds of 3 meters, true wind direction, temperature, atmospheric pressure, relative humidity, etc. Meteorological parameters and hydrological parameters such as sea surface temperature, flow velocity, and flow direction. The network application can effectively compensate for the lack of spatial resolution of existing observation methods, provide high-quality ocean-gas interface real-time observation data support for ocean analysis and forecasting systems, and meet marine scientific research needs such as air-sea interface interaction and global climate change. Further improve the ability of pre-alerts such as emergency maneuver observations at sea, on-site protection of the marine environment, and disaster prevention and mitigation.

In this survey and application at sea, the buoy firstly completed the comparison with the international standard anchor system air-sea flux buoy, and its observation data quality reached the international advanced level, fully validating the scientific and accurate observation of the floating platform observation. Sex. At the same time, this buoy was the first time in the world to successfully perform drifting network observations of the spatial-temporal resolution of mesoscale vorticity, providing a new type of effective observation method for the research of air-sea interaction under the mesoscale vortex environment, supporting and promoting the Theoretical Study on Air - Sea Interaction in Scale Processes .

According to reports, “drifting air-sea buoy buoy” is a low-cost, easy-to-put, maintenance-free, disposable small-scale air-sea interface drift observation system. Its performance in the cyclonic process and large waves has fully verified its The observational reliability under severe sea conditions lays a solid foundation for the popularization and application of buoys.
