이산적 모델을 이용한 열염분순환의 장주기 변동 구조 연구

Abstract

From idealized numerical experiments with a depth level coordinate ocean circulation model (GFDL MOM3), the structure of interdecadal variability from thermally driven circulations has been investigated. temperature and velocity anomalies circulate cyclonically in high latitudes mainly due to interactions among temperature gradient anomalies, the subsequent velocity anomalies, and the continents that block the velocity anomalies over the northeastern corner. A phase lag between the meridional temperature gradient and overturning circulation is established as a consequence of the variability.
