摘要：哈德利中心全球环境模型第 2 版地球系统 (HadGEM2-ES) 气候模型受到大气 CO2 140 年复合增加 1% yr−1 的影响，随后 CO2 减少 1% yr−1 回到起始水平。进行类似的仅大气模拟来诊断与有效辐射强迫和快速调整相关的变化成分。残余变化与辐射反馈相关，辐射反馈与全球平均表面气温的变化呈线性相关，并且在本实验设计下被发现是可逆的，即使对于区域云反馈变化也是如此。云的调整与云量的变化有关，几乎没有迹象表明云光学深度有任何大规模的变化。植物生理强迫在确定该模型中的云调整方面起着重要作用，并且是陆地上空低层云变化的主要贡献。低级云调整与...的变化相关。
AbstractThe Hadley Centre Global Environment Model, version 2–Earth System (HadGEM2-ES) climate model is forced by a 1% yr−1 compound increase in atmospheric CO2 for 140 years, followed by a 1% yr−1 CO2 decrease back to the starting level. Analogous atmosphere-only simulations are performed to diagnose the component of change associated with the effective radiative forcing and rapid adjustments. The residual change is associated with radiative feedbacks that are shown to be linearly related to changes in global-mean surface air temperature and are found to be reversible under this experimental design, even for regional cloud feedback changes. The cloud adjustment is related to changes in cloud amount, with little indication of any large-scale changes in cloud optical depth. Plant physiological forcing plays a significant role in determining the cloud adjustment in this model and is the dominant contribution to the low-level cloud changes over land. Low-level cloud adjustments are associated with changes i...
