A study on the China Coastal Waters Appeared in the Surrounding Seas of Jeju Island by using Satellite Data

摘要

CCW(China Coastal Waters) usually appeared from June through October every years, and it appeared very strong in August. For the Power Spectrum Density, SLA(Sea Level Anomaly) and SST(Sea Surface Temperature) remarkablely peaked on the annual period, semi-annual period and 3-monthly period. The rest of period is considered involved with CCW and Kurosio Current. Distribution of salinity appeared from western part of Jeju, progressing toward to East. After that we can know the influence became weak owing to Kurosio Current of the eastern part of Jeju Island. In the analysis of EOF for SLA and SST, the variance of SLA and SST presented 55.70% and 98.09% in the first mode, respectively. The western part of Jeju Island more influenced by CCW than the eastern part of Jeju Island, at power spectrum density of SLA though EOF. The result of power spectrum density was similar to every sea area(Yangtz estuary, Je_W and Je_E) for SST. So that CCW may be influenced about 260 days frequency for SST.
