Upper Ocean Response of Yongxing Island Area to Typhoon ‘Kujira’ in the South China Sea from Multiple-Satellite and Fixed-Point Observation

摘要

The passage of typhoon Kujira was observed in detail by multiple satellites and observation data. Satellite observations revealed typhoon-induced sea surface temperature and sea surface salinity decrease, respectively and increase in the chlorophyll concentration. The observation data showed that the direction of the flow field above 450 m was affected by wind stress when the Typhoon transit and after the typhoon lasted more than a week. The typhoon has had a significant impact on depth above 450 m. It improves the barren sea surface environment of Yongxing Island area in summer and is conducive to the growth of Marine life.
