石渡等人。 （2007）（https://doi.org/10.1029/2006JD007368）研究了不同太阳常数值下灰色大气的多重平衡解，利用两种模型，即一维能量平衡模型和具有简化物理过程的大气环流模型（GCM），这两种模型都允许失控温室状态的存在。该研究被撤回，因为他们的 GCM 中存在一个错误，影响了该研究的定量方面。在这里，我们使用适当校正的模型重新执行所有 GCM 实验来修改研究。重新实验的结果表明，在太阳常数-冰线纬度平面上绘制的气候状况图的主要特征基本上没有变化，除了Ishiwatari等人存在的无冰平衡状态。 (2007) (https://doi.org/10.1029/2006JD007368) 现在消失了。已证实存在部分冰雪覆盖状态、全球冰雪覆盖状态和失控温室状态。对于太阳常数的中间值，这三种状态共存。尽管部分冰覆盖状态的临界纬度向赤道延伸，但大冰盖不稳定性的存在也得到了证实。也和之前一样，小冰盖的不稳定似乎没有出现。
Ishiwatari et al. (2007) (https://doi.org/10.1029/2006JD007368) investigated multiple equilibrium solutions of a gray atmosphere for various values of solar constant, utilizing two types of models, namely, a one‐dimensional energy balance model and a general circulation model (GCM) with simplified physical processes, both of which permit existence of the runaway greenhouse state. The study was retracted, since there was a bug in their GCM that affected quantitative aspects of the study. Here, we revise the study with re‐performing all of the GCM experiments using an appropriately corrected model. The results of re‐experiments show that the main features of the climate regime diagram drawn in the solar constant ‐ ice line latitude plane are mostly unchanged, except that the ice‐free equilibrium state, which existed in Ishiwatari et al. (2007) (https://doi.org/10.1029/2006JD007368) now disappears. It is confirmed that there are the partially ice‐covered state, the globally ice‐covered state, and the runaway greenhouse state. These three states coexist for intermediate values of solar constant. The existence of the large ice cap instability is also confirmed, although the critical latitude of the partially ice‐covered state extends equatorward. Also same as before, the small ice cap instability does not seem to appear.
