摘要: Based on the National Center for Atmospheric Research (NCAR) Climate System Model version 1 (CSM-1), a Flexible coupled General Circulation 0 (FGCM-0) is developed in this study through replacing CSM-1’s oceanic component model with IAP L30T63 global general circulation and some necessary modifications of other models. After FGCM-0 spun up dozens years, it has been run 60 years without flux correction. The does not only show reasonable long-term mean climatology, but also reproduce lot features interannual variability climate, e.g. ENSO-like events tropical Pacific Ocean dipole mode pattern Indian Ocean. Comparing NCAR CSM-1, common are found, overestimation sea ice North simulated double ITCZ etc. further analyses suggest that they may be attributed to errors atmospheric model.
