论文摘要
我们使用理想化的三维一般循环模型来研究缓慢旋转潮汐锁定的陆地行星上无效的冷陷阱的浓缩气氛。特别是，我们在薄而温带的气氛中显示了气候动力学的气候动力学。在以前的作品中讨论了我们稀薄和温带的气氛与温暖而厚的气氛接近水蒸气失控温室之间的相似之处，包括白天和夜晚半球之间的热发射的逆转。与取决于大气水蒸气的绝对量的水蒸气的过境光谱不同，白天和夜间热发射之间的对比度提供了有关水蒸气与背景大气的相对比，以及附近的大气压力的相对比率，以及在潜在的居住世界上的夜间夜行和发射水平。
We use an idealized three-dimensional general circulation model to study condensible-rich atmospheres with an ineffective cold trap on slowly rotating tidally locked terrestrial planets. In particular, we show the climate dynamics in a thin and temperate atmosphere with condensible water vapor. The similarities between our thin and temperate atmosphere and the warm and thick atmosphere approaching the water vapor runaway greenhouse in previous works are discussed, including the reversal of the thermal emission between the day and night hemispheres. Different from the transit spectroscopy of water vapor that depends on the absolute amount of atmospheric water vapor, the contrast between the dayside and nightside thermal emission provides information regarding the relative ratio of water vapor to the background atmosphere as well as the atmospheric pressure near the substellar tropopause and the emission level on the nightside on potentially habitable worlds.
