CMIP6火山强迫的气候响应模拟比较计划（VolMIP）概况与评述

Short commentary on CMIP6 Model Intercomparison Project on the climatic response to Volcanic forcing(VolMIP)

为揭示造成火山强迫气候响应模拟不确定性的原因,第六次国际耦合模式比较计划(CMIP6)设立了火山强迫的气候响应模拟比较计划(VolMIP)。该计划由基于历史火山爆发的理想火山扰动试验组成,包括三组主要的试验:第一组关注短期(季节至年际)大气动力响应;第二组关注海气耦合系统的长期(年际至年代际)响应;第三组关注气候系统对火山群的响应。VolMIP旨在通过给定相同的辐射强迫并进行多成员集合模拟,揭示模式对外强迫响应的不确定性,通过设定不同的背景气候态,阐明内部变率和外强迫对气候响应的相对贡献。

In order to achieve a better understanding of the inter-model uncertainties in the response to volcanic forcing,the Model Intercomparison Project on the climatic response to Volcanic forcing(VolMIP)has been endorsed to the CMIP6.It consists of a set of idealized volcanic perturbation experiments,which include three main experiments:the first is designed to investigate the short-term(seasonal to interannual)atmospheric response,the second is designed to investigate the long-term(interannual to decadal)response of the coupled climate system,and the third is designed to investigate the climatic response to close successions of volcanic eruptions.VolMIP will provide the same volcanic aerosol data set for each experiment and conduct large simulation ensembles,which allows to investigate the inter-model differences.A set of initial conditions are also defined to assess the different contribution of the internal variability and external forcing to the climatic response.
