NOAA/GFDL 결합 기후 모델에서의 북태평양 수괴

Abstract

Two NOAA/GFDL coupled climate models are compared while focusing on the North Pacific circulation and water masses. The two coupled models, CM2G and CM2M, share the samecomponents except the oceans, which are an isopycnal model GOLD in CM2G, and MOM4 in CM2M. In general both models reproduce known features such as the North Pacific Mode waters and Intermediate Waters, but there are some differences. CM2G produces stronger Kuroshio and the Kuroshio and Oyashio Fronts are reproduced better compared to CM2M. Concerning the North Pacific Mode Waters, temperature and salinity are better withCM2M but volumetric census and stratification are better with CM2G. For the North Pacific Intermediate Water, CM2M shows relatively young water originating from the subpolar ocean, but CM2G shows that young water is produced north of the Kuroshioextension.
