북서태평양 지역기후모형 개발: 현재 해양기후 모사 분석

Abstract

Recent study based on satellite and Korea Oceanographic Data Center (KODC) observations conducted over the eastern coast of Korea shows the linear trend of 10m ocean temperature during 1961-2007 years is negative in coastal areas, in contrast with positive trend offshore (Park et al., 2010). However, simulating and predicting climate variability from GCMs is difficult due to too coarse resolution of approximately 100-200 km to resolve the complex air-sea interaction system in marginal and coastal areas. The regional climate models (RCMs) have been used to downscale the GCMs output to obtain high-resolution results. Therefore, we focused on a developed regional ocean climate model using Regional Ocean Modeling System (ROMS) to study interannual variation of ocean property of present climate for the western North Pacific marginal seas.st with positive trend offshore (Park et al., 2010).
