论文摘要
在这项研究中，我们将两个分析能量平衡模型与对倾斜的明确依赖性进行比较，以研究不同稳定冰构型的可能性。我们比较了使用不同的热传输方法和不同的日光分布的模型的结果。我们表明，只要倾斜分布足够准确，任何倾斜的稳定部分冰盖都是可能的。此外，随着不同的模型参数的变化，我们量化了向雪球状态的过渡的严重性。根据较早的研究，在这两种模型中，对反照率对比度和跨纬度的能量传输的较高值的过渡更为严重。但是，我们发现两种模型中的雪球过渡都不可能。这项工作足够一般，可以应用于任何快速旋转的行星，可用于研究其他恒星宜居区域内行星上滚雪球过渡的可能性。
In this study, we compare two analytic energy balance models with explicit dependence on obliquity to study the likelihood of different stable ice configurations. We compare the results of models with different methods of heat transport and different insolation distributions. We show that stable partial ice cover is possible for any obliquity, provided the insolation distribution is sufficiently accurate. Additionally, we quantify the severity of the transition to the Snowball state as different model parameters are varied. In accordance with an earlier study, transitions to the Snowball state are more severe for higher values of the albedo contrast and energy transport across latitudes in both model; however, we find that the Snowball transition is not equally likely across both models. This work is general enough to apply to any rapidly rotating planet and could be used to study the likelihood of Snowball transitions on planets within the habitable region of other stars.
