对地球气候系统的科学认识，包括气候系统可能如何对人为扰动作出反应的核心问题，在大气环流模型和地球系统模型中得到了全面的体现。诊断模拟的气候响应，并比较不同模型的响应，关键取决于如何驱动GCM/ESM的透明假设-特别是因为实施可能涉及主观决定，并且在进行相同实验的建模组之间可能存在差异。本文概述了气候强迫和设置气象局哈德利中心ESM，HadGEM 2-ES的CMIP 5的百年实验。我们记录规定的温室气体浓度，气溶胶前体，平流层和对流层臭氧假设，以及土地利用变化和自然强迫的HadGEM 2-ES的历史和未来的实验后，代表性浓度路径的实施。此外，我们提供的细节HadGEM 2-ES合奏成员是如何初始化的控制运行和如何古气候和AMIP实验，以及“排放驱动”RCP实验进行。
The scientific understanding of the Earth's climate system, including the central question of how the climate system is likely to respond to human-induced perturbations, is comprehensively captured in GCMs and Earth System Models (ESM). Diagnosing the simulated climate response, and comparing responses across different models, is crucially dependent on transparent assumptions of how the GCM/ESM has been driven - especially because the implementation can involve subjective decisions and may differ between modelling groups performing the same experiment. This paper outlines the climate forcings and setup of the Met Office Hadley Centre ESM, HadGEM2-ES for the CMIP5 set of centennial experiments. We document the prescribed greenhouse gas concentrations, aerosol precursors, stratospheric and tropospheric ozone assumptions, as well as implementation of land-use change and natural forcings for the HadGEM2-ES historical and future experiments following the Representative Concentration Pathways. In addition, we provide details of how HadGEM2-ES ensemble members were initialised from the control run and how the palaeoclimate and AMIP experiments, as well as the "emission-driven" RCP experiments were performed.
