在美国国家大气研究中心（ＮＣＡＲ）气候系统模式（ＣＳＭ－１）的基础上，通过使用中国科学院大气物理研究所发展的Ｔ６３／Ｌ３０全球海洋环流模式替代ＣＳＭ－１的海洋分量模式以及其它一些必要的改动发展了一个灵活的海气耦合环流模式的初始版本（ＦＧＣＭ－０）。在耦合模式ＦＧＣＭ－０的几十年的ｓｐｕｎ—ｕｐ试验之后，这个耦合模式在没有使用任何通量订正的情形下积分了６０年。该模式不仅显示了合理的长期平均气候，而且可以重现许多年际气候变化的特征，如类似ＥＮＳＯ的事件和赤道印度洋的偶极子模态。与ＮＣＡＲ的ＣＳＭ－１相比，可以发现一些共同存在的问题，如对北太平洋海冰的过高估计和模拟的双“赤道辐合带（ＩＴＣＺ）”现象等。进一步的分析表明，这些现象可能是由大气模式本身的误差引起的。
Based on the NCAR Climate System Model (CSM-1) and by replacing the ocean component mode of CSM-1 with the T63 / L30 global ocean circulation model developed by the Institute of Atmospheric Physics of the Chinese Academy of Sciences and other necessary The development of a flexible coupled version of the coupled atmospheric circulation model (FGCM-0) was developed. After decades of spun-up tests in coupling mode FGCM-0, this coupling mode has been integrated for 60 years without any flux correction. This model not only shows a reasonable long-term average climate, but also reproduces many of the characteristics of inter-annual climatic changes such as ENSO-like events and dipolar modes in the equatorial Indian Ocean. In contrast to NCAR’s CSM-1, co-existing problems such as overestimation of North Pacific sea ice and simulated twin “Equatorial Convergence Zone (ITCZ)” phenomena can be found. Further analysis shows that these phenomena may be caused by the error of the atmospheric model itself.
