수온과 기후 지수 자료를 이용하여 한국주변해 상층부의 수온변동과 북태평양 기후체제와의 관계를 분석하였다. 1970, 1980 그리고 1990년대 후반에 발생한 기후체제전환은 해양생태계의 구조 변화에 중요한 영향을 끼쳤다. 북서태평양 대륙주변부에 위치한 우리나라 주변해역 또한, 10년 이상의 장주기적인 변화의 영향을 받지만, 해역별 반응은 다르다. 동해, 서해, 남해 상층부(10 m)의 경우 1988년의 기후체제전환은 3개 해역의 상층부 수온변화에서 동시에 나타난다. 반면, 1998년은 동해남부해역과 서해, 1976년의 기후체제전환은 전 해역의 겨울철 수온변화에서만 그 영향이 나타난다. 1998년 기후체제전환 이후, 서해, 동중국해, 동해 남부의 수온은 점차 감소하지만, 동해 북부해역은 1988년 기후체제전환 이후 증가하는 형태이다.

Temperature variability at the upper layer related to climate regime shifts in the Korean waters was illustrated using water temperature, climate index. Three major climate regime shifts (CRS) in 1976, 1988 and 1998 in north Pacific region had an significant influence on the major marine ecosystems structure pattern. Three marginal seas around Korean peninsula; East Sea, East China Sea and Yellow Sea also got important impact from this kind of decadal shift. We used 10m sea water temperatures in four regions of Korean waters since 1950 to detect major fluctuation patterns both seasonally and also decadal shift. 1988 CRS was occurred in all of the study areas in most seasons however, 1998 CRS was only detected in the Yellow Sea and in the southern part of the East Sea. 1976 CRS was detected in all of the study area mainly in winter. After 1998 CRS, the water temperature in the southern part of the East Sea, East China Sea and Yellow Sea were going into decreased pattern; however, in the northern part of the East Sea, it was further shifted to increasing pattern which was started from 1988 CRS period.
