1976년의 북태평양에서의 기후변동이 한반도 해역에서도 발생하였는가?

Abstract

In the north Pacific, climate showed a decadal scale of abrupt change, called climate regime shift. Recent change was happened in 1976, and it persisted over ten years until late 1980s, showing the intensified low pressure systems replaced the high in the north part of Pacific Ocean. Accordingly, primary production, species composition and its distribution in marine ecosystem were also changed due to the increased sea water temperature and storm intensity. In the Korean waters, there might be some changes in sea water properties and ecosystem structure. Warm water temperatures were appeared during 1975-1980 in the East Sea, and the catches of some fish species had a tendency of decrease or increase after mid1970s, though catch records does not always indicate the stock condition. Much attention should be payed to find evidences in climate regime shift in Korean waters.d the high in the north part of Pacific Ocean.
