CMIP6云反馈模式比较计划(CFMIP)概况与评述

Short commentary on CMIP6 Cloud Feedback Model Intercomparison Project(CFMIP)

世界气候研究计划(WCRP)于2003年支持开展云反馈模式比较计划(CFMIP)。目前已经开展到第三阶段(CFMIP-3)。相比前两阶段的试验,CFMIP-3试验设计更加丰富、具体,除增加CMIP6DECK和Historical试验的观测模拟器(COSP)输出外,还围绕着回答7个云反馈相关的科学问题,设计了Tier-1(必做)和Tier-2(可选)两类试验。CFMIP将气候模拟、观测研究和过程模拟等几个研究方向更紧密地联系在一起,并为理解和模拟云及其辐射反馈的气候贡献提供更深刻的认识和分析手段。

Cloud-radiation feedback is considered as one source of large uncertainties in climate simulation.To improve understanding of cloud-climate mechanisms and evaluating cloud processes and cloud feedback in climate models,the Cloud Feedback Model Intercomparison Project(CFMIP)is firstly endorsed by the World Climate Research Programme(WCRP)in 2003.Now,CFMIP has entered its third phase,CFMIP-3.Comparison with its two previous phases,the CFMIP-3 experiments have more types and more specific scientific questions to be addressed.Besides adding model outputs in the CMIP6 DECK and Historical experiments using CFMIP Observation Simulator Package(COSP),the CFMIP-3 experiments include Tier-1(required)and Tier-2(optional)types to address 7 cloud-related questions.The CFMIP brings climate modelling,observational and process modelling communities together and provides tools for evaluating and understanding the simulations of clouds and cloud feedbacks in climate models.
