복합위성자료(Topex/Poseidon, Jason-1, ERS, Envisat)를 이용한 한반도 주변해역에서의 해수면 고도 변화와 해수면 온도의 상관성 연구 = Variation of the Sea Surface Height around the Korean Peninsula with the Use of Multi-satellite Data(Topex/Poseidon, Jason-1, ERS, Envisat) and its Association with Sea Surface Temperature

다국어 초록 (Multilingual Abstract)

Sea surface height (SSH) around the Korean Peninsula was investigated as a rising rate of 3.89 mm yr-1 on the average from 1993 to 2005, which is 1.3 times higher rising rate, compared to the world ocean. In the present study, to investigate SSH changes in regional sections of the East Sea, the Yellow Sea, the South Sea, and the Korea Strait, DT-MSLA (Delayed Time-Maps of Sea Level Anomalies) with multi-satellite data (Topex/Poseidon, Jason-1, ERS, Envisat), provided by AVISO (Archiving, Validation and Interpretation of Satellite Oceanographic data), was used. The periodicity in interannual variability was dominant for 4~5 year in summer, and 3 year in winter as well as an increasing trend. The amplitude and phase for the annual and semi-annual mode in SSH and SST were investigated with harmonic analysis. The geographical distribution of amplitudes for comparison of SSH and SST are slightly reverse in southwest-northeast tilted direction. The monthly SST and SSH is highly correlated correlation coefficient about 0.7 with lag of one or two months over the East Sea and the South Sea during June-August. These results suggest that the Kuroshio stream is dominant during summer over these regions.
