Abstract
In the East Sea of Korea the vertical structure functions of the temperature field were evaluated and the characteristic thermal zone was classified by the use of the empirical orthogonal function(EOF) method. The East Sea of Korea within the hydrographic lines of 10-107 of the Fisheries Research and Development Agency of Korea(FRDA) can be divided into three thermal regions by the characteristics of the vertical temperature variability. They are the North Korean Cold Current(NKCC) region near the coast which extends parallel to the north-south direction, the Warm-Core(WC) region which dominates almost all the hydrographic stations of the Line 104 of the FRDA and occupies a few stations of the Line-103 and -105 with its axis at the Line 104, and the East Korea Warm Current(EKWC) region which is bisected into the northern and the southern part by the WC region, respectively. Considering the two most important modes,
본 연구는 경험적 직교함수 방법을 적용하여 동해 중서부 해역에서 수직적인 수온 분포의 공간적 특성을 해역별로 구분한 후 특징적인 수온의 수직구조 함수를 제시하였다. 수산진흥원 관측범위 중에서 102-107 정선을 포함하는 동해 중서부 해역은 연안을 따라 남북방향으로 발달하는 북한한류수역, 외해쪽의 동한난류수역과 104정선을 축으로 동서방향으로 발달하는 난수괴역으로 구분되며 동한난류수역은 난수괴역에 의해 남북으로 양분된다. 제2모드함수까지 이용하여 설명되는 수온의 변동성은 북한한류수역에서는 총 분산의
