미래 기후 조건하에서 동중국해의 해양순환 모의

Abstract

North Pacific ocean climate model experiments have been conducted to examine a possible change of ocean environment under global warming in the East China Sea (ECS) which is not adequately resolved in global climate models due to a coarse spatial resolution. Global climate model simulations for the 20th century and for the future climate with IPCC A1B scenario were used as the prescribing conditions. Compared to the global climate models, regional ocean climate model predicted the detailed patterns of temperature and current fields under the future climate condition; instead of simple structure like an overall temperature rise as in global climate models, locally different rising/falling trend of temperature in the ECS. Future temperature and salinity changes are prominent in the Changjiang bank shallower than 70 m in the western region of the ECS, while those are relatively small in the eastern region where the Kuroshio-branched current flows northeastward.
