Buoy observation data verification and application

Abstract

The buoy automatic observation is greatly influenced by the marine environment. The quality of buoy observation data needs to be tested before it is applied. In this paper, buoy observation data is verified with the ocean station and ocean section observation data, and the reliability of buoy observation is analyzed. On this basis, the hydrometeorological condition in the central Bohai Sea is analyzed for surface water temperature, surface salinity, sea surface air temperature and sea surface pressure. The results show: The reliability and continuity of buoy observation of sea surface water temperature, sea surface air temperature and sea surface pressure are high; the reliability of sea surface salinity, average wind speed, average wind direction, significant wave height, significant wave period, average wave height and average wave period are low. The hydrometeorological condition in the central Bohai Sea analyzed by buoy observation data is basically consistent with the existing research conclusions. The lowest water temperature in the central Bohai Sea occurs in February.
