在过去的十年里，围绕太阳以外的恒星运行的行星的发现加速了，随着新的太空和地面观测站采用下一代仪器在天空中寻找宜居世界，这一趋势将继续下去。然而，许多因素和过程都会影响行星的宜居性，必须了解这些因素和过程才能准确确定行星的宜居性潜力。虽然气候模型长期以来被用来理解和预测地球上的气候和天气模式，但越来越多的研究人员已经开始将这些模型应用于太阳系外行星。这项工作让我们更好地了解轨道、表面和大气特性如何影响行星气候和宜居性；这些气候影响可能如何随着不同的恒星和行星环境而变化；以及新发现的行星的宜居性和观测特征如何受到这些气候因素的影响。这篇综述总结了系外行星气候学这个新兴领域的起源和演变，讨论了最近使用计算机模型层次结构来识别那些最有能力支持生命的行星的工作，并提供了对这个快速发展的系外行星科学子领域的未来方向的一瞥。
The discovery of planets orbiting stars other than the Sun has accelerated over the past decade, and this trend will continue as new space- and ground-based observatories employ next-generation instrumentation to search the skies for habitable worlds. However, many factors and processes can affect planetary habitability and must be understood to accurately determine a planet’s habitability potential. While climate models have long been used to understand and predict climate and weather patterns on the Earth, a growing community of researchers has begun to apply these models to extrasolar planets. This work has provided a better understanding of how orbital, surface, and atmospheric properties affect planetary climate and habitability; how these climatic effects might change for different stellar and planetary environments; and how the habitability and observational signatures of newly discovered planets might be influenced by these climatic factors. This review summarizes the origins and evolution of the burgeoning field of exoplanet climatology, discusses recent work using a hierarchy of computer models to identify those planets most capable of supporting life, and offers a glimpse into future directions of this quickly evolving subfield of exoplanet science.
