초록

겨울철인 1998년 2월과 1999년 1월, 4월에 남해와 동중국해 북부해역에서 형성되는 전선의 분포와 구조를 파악하기 위하여 광역의 종합해양관측을 수행하였다. 관측해역에서 구분된 수계들은 대마난류기원 고온수, 황해냉수(북부냉수 혹은 중앙냉수) 그리고 남해저온수로 분류된다. 황해남부 해역에서는 제주도 서쪽을 우회하여 제주해협으로 유입하는 대마난류기원 고온수가 '┍'자 형태의 기본적 전선을 이루며 대흑산도 남쪽에 황해중앙냉수와 그리고 양자천퇴 동부에서 황해북부냉수와 만나고 있다. 이 전선은 고온수가 황해 북서부로 확장하는 세기에 의해 전선 모서리 형태와 위치가 달라진다. 양자천퇴 부근과 한반도 남서단 외측에서의 전선위치와 구조도 관측시기에 따라 변화한다 남해 전선에서는 연안 저온수가 국지적 냉각에 의해 독립적으로 형성된 수계로서 해저사면을 따라 침강한다. 이러한 겨울철 전선분포의 변화와 전선구조가 변화되는 과정은 탁월풍에 의한 순풍류 및 역풍류, 해수면을 통한 열수지 그리고 전선사이의 밀도차이에 의한 것으로 설명되었다.

During the winter in February 1998, January and April 1999, interdisciplinary research was conducted in a large area including the South Sea of Korea and northern East China Sea to examine distribution and structure. Water masses identified from the observed data are Warm Water originated from Tsushima Warm Current, Yellow Sea Cold Water (Northern or Central Cold Water) and Korean Southern Sea Cold Water. In the southern Yellow Sea, Warm Water originated from Tsushima Warm Current, flowing into the Cheju Strait after turning around the western Cheju Island, makes a front of '┍' shape, which is bounded by the Yellow Sea Central Cold Water in the southern part of Daeheuksan Island and by the Yellow Sea Northern Cold Water in the eastern part of the Yangtze Bank. This front changes its corner shape and position with strength of the warm water extension toward northwestern Yellow Sea. The position and structure of the fronts off the southwestern tip of the Korean peninsular and near the Yangtze Bank varies with observation period. In the front in the South Sea of Korea, cold coastal water which if formed independently due to local cooling, ,sinks along the sloping bottom. We explained the processes of variations in the distribution and structure of these winter fronts in terms of up-wind and down-wind flow by the seasonal monsoon, heat budget through the sea surface and density difference across the fronts.
