대마난류의 수송량 변동이 동해 순환에 미치는 영향에 대한 수치실험

Abstract

Influence of long term variation of Tsushima Warm Current(TWC) transport on the circulation of the East Sea has been investigated using a numerical model(RIAM Ocean Model). It is interesting that the impacts of TWC transport change does not confined in the upper ocean. Most prominent influences are shown in the mixed layer depth distribution and meridional overturning strength. It is concluded that the inter-annual variability of TWC transport, it it exists, may be very important to understand the recent slow down of the convection in the East Sea. Decreased TWC transport deepen the MLD and enhances meridional overturning strength. It is suggested that the lateral heat flux in the Korea Strait is also important as well as air temperature warming at the surface.
