Although fundamental to the planetary radiative balance, aerosol impacts are highly uncertain in climate simulations because of the uneven distribution of aerosol sources and the complex interactions with radiation and clouds that are difficult to represent in climate models. This study proposes that aquaplanet configurations represent an idealized framework to investigate aerosol effects. As a simple demonstration, a series of aquaplanet simulations with the Community Atmosphere Model version 6 shows that the spatial distribution of aerosol emissions changes the aerosol effective radiative forcing even with unchanged total emissions. Some statistical properties of the simulations are presented to show that relatively short model integrations yield robust results. Much of the aerosol effect is shown to arise from aerosol‐cloud interactions, especially through rapid adjustments associated with the aerosol lifetime effect that alter the cloud optical thickness.

水上行星作为检验气溶胶效应的框架

尽管是行星辐射平衡的基础，但由于气溶胶源分布不均以及与辐射和云之间的复杂相互作用（在气候模型中很难表示），因此在气候模拟中气溶胶的影响高度不确定。这项研究提出，水上飞机的配置代表了研究气溶胶效应的理想框架。作为简单的演示，使用社区大气模型版本6进行的一系列滑水飞行器模拟显示，即使总排放量不变，气溶胶排放物的空间分布也会改变气溶胶有效的辐射强迫。给出了仿真的一些统计属性，以表明相对较短的模型集成会产生可靠的结果。大量的浮质效应是由浮云相互作用产生的，
