Sea surface salinity changes around the Jeju Island after Typhoon Chaba

摘要

Typhoon Chaba impacted the freshwater-enriched ocean in the East China Sea bringing strong wind in October 4-5, 2016. The heavy storm vertically mixed the coastal water around the Jeju Island. The signature of vertical mixing around Jeju Island was indicated by the elevation of sea surface salinity(SSS) observed by NASA SMAP(Soil Moisture Active Passive) Satellite. Moreover, the spatial size of the freshwater plume(<;30psu) near the mouth of the Changjiang river diminished. Using the SMAP satellite which collects the SSS under the cloudy condition, in the future, the role of the Typhoon relevant with the ecosystem in the ECS needs to be studied.
