Abstract

This is the first attempt to produce simultaneous surface current field from satellite altimeter data for the entire East Sea and to provide surface current information to users with formal description. It is possible to estimate surface geostrophic current field in near real-time because satellite altimeters and coastal tide gauges supply sea level data for the whole East Sea. Strength and location of the major currents and meso-scale eddies can be identified from the estimated surface geostrophic current field. The mean locations of major surface currents were explicated relative to topographic, ocean-surface and undersea features with schematic representation of surface circulation. In order to demonstrate the practical use of this surface current information, exemplary descriptions of annual, seasonal and monthly mean surface geostrophic current distributions were presented. In order to objectively classify surface circulation patterns in the East Sea, empirical orthogonal function (EOF) analysis was performed on the estimated 16-year (1993-2008) surface current data. The first mode was associated with intensification or weakening of the East Korea Warm Current (EKWC) flowing northward along the east coast of Korea and of the anti-cyclonic circulation southwest of Yamato Basin. The second mode was associated with meandering paths of the EKWC in the southern East Sea with wavelength of 300 km. The first and second modes had inter-annual variations. The East Sea surface circulation was classified as inertial boundary current pattern, Tsushima Warm Current pattern, meandering pattern, and Offshore Branch pattern by the time coefficient of the first two EOF modes.

이 연구는 인공위성 고도계로 관측한 해수면 높이 자료를 이용하여 동해 표층해류를 생산하고, 동해 전체 영역에 대하여 동시성 있는 표층해류 분포를 동해 해류 정보 사용자에게 제공하기 위한 최초의 시도이다. 동해 전 영역에서 인공위성 고도계와 연안 조위관측소의 해수면 높이 자료를 동시에 얻을 수 있으므로 준실시간으로 넓은 해역에 대하여 동시성 있는 표층 지형류의 산출이 가능하다. 산출된 동해 표층 지형류로부터 주요 해류의 위치와 세기 그리고 중규모 이상의 소용돌이 발달 양상을 살펴볼 수 있다. 따라서 이들 해류의 이름과 평균적인 위치를 알 수 있도록 동해 해양지명에 대한 명칭과 위치를 기술하고, 개념적인 해류도를 제시하였다. 동해 해류정보가 실제 실용화될 수 있도록 인공위성 고도계 자료를 이용하여 산출한 지형류의 월 계절 연도별 해류 분포 예를 들고, 각 해류 분포를 설명하였다. 또한 시 공간적으로 변화하는 동해 표층해류 분포 형태를 객관적으로 분류하기 위하여 16년(1993~2008년)간의 표층해류 자료를 경험직교함수(Empirical Orthogonal Function, EOF)를 이용하여 분석하였다. EOF분석 제1모드(mode)는 주로 한국 동해안을 따라 북쪽으로 흐르는 동한난류와 야마도분지 남서부 시계방향 순환의 강화 또는 약화를 나타냈다. 제2모드는 동한난류가 동해 남부를 가로지르며 사행하는 정도를 나타냈으며, 해류 사행의 파장은 약 300 km이었다. 제1모드와 제2모드가 모두 해류의 연간 변동성을 나타냈으며, 제1모드와 제2모드의 시간계수에 따라 동해 표층해류 분포를 관성 경계류 패턴(pattern), 대마난류 패턴, 사행 패턴, 외해분지류 패턴으로 분류할 수 있다.
