The global Ocean General Circulation Model(OGCM)is a critical component of Earth system modeling and plays an essential role in climate projections and marine environmental forecasting.Herein,the history of global OGCM models is systematically reviewed and significant scientific and recent technological advancements are summarized.This review covers three topics involving the core technology of OGCMs:the dynamical core,physics or physical parameterization,and soft-hardware configuration.In the dynamic core,the latest developments in horizontal discretization methods,vertical coordinate schemes,and multi-resolution strategies are explored.Regarding physics,the focus has been on the progress of mesoscale,sub-mesoscale,and boundary-layer mixing parameterizations.In the soft-hardware configuration section,the current status and prospects for the application of heterogeneous computing architectures and artificial intelligence technology in global OGCMs are discussed.The advancement of the LASG/IAP Climate System Ocean Model,a fully autonomous Chinese global OGCM,is also highlighted.Based on key trends and novel ideas in the field of global OGCMs,suggestions are provided for Chinese researchers and relevant policymakers to comprehensively advance R&D strategies and long-term planning for fully autonomous global OGCMs.
