第六次国际耦合模式比较计划(CMIP6)评述

Commentary on the Coupled Model Intercomparison Project Phase 6(CMIP6)

世界气候研究计划(WCRP)发起了新一轮的国际耦合模式比较计划(CMIP6),目的是回答当前气候变化领域面临的新的科学问题,为实现WCRP“大挑战”计划所确立的科学目标提供数据支撑。文中回顾了CMIP的发展历程,介绍了CMIP6的组织思路,阐述了CMIP6核心试验及23个模式比较子计划(MIPs)的科学关注点,总结了参与CMIP6的全球模式概况以及中国的贡献。最后,从继承性和创新性等角度对CMIP6进行了评述,指出了CMIP6组织和实施中存在的问题,并对CMIP未来的发展进行了展望。

The World Climate Research Programme(WCRP)has launched a new phase of the Coupled Model Intercomparison Project(CMIP6),which aims to address new scientific questions in climate change field and provide data support for the scientific goals established by the WCRP Grand Challenges program.This paper reviews the development history of CMIP,introduces the background and organization of CMIP6,provides the description of the CMIP6 DECK experiments and the scientific foci of the 23 CMIP6-endorsed MIPs,briefly describes the CMIP6 models and Chinese contributions.Finally,the authors review the CMIP6 from the perspectives of inheritance and innovation,summarize the issues in the organization and implementation of CMIP6,and discuss the prospects for the future development of CMIP.
