气候变化热力学:广义敏感性

Thermodynamics of Climate Change: Generalized Sensitivities

V. Lucarini, K. Fraedrich, F. Lunkeit

摘要:

使用最近开发的形式主义,我们提出了一个深入的分析,如何气候系统的热力学随CO2浓度的变化进行实验与一个简化的,但类似地球的气候模式。我们发现,除了全球平均的地面温度外,系统的Lorenz能量循环强度、卡诺效率、熵产生和不可逆度都与CO2浓度的对数成线性关系.这里提出的广义敏感性表明,气候系统变得更低的效率,更不可逆,并具有较高的熵产生,因为它变得更温暖。

英文摘要:

Using a recently developed formalism, we present an in-depth analysis of how the thermodynamics of the climate system varies with CO2 concentration by performing experiments with a simplified yet Earth-like climate model. We find that, in addition to the globally averaged surface temperature, the intensity of the Lorenz energy cycle, the Carnot efficiency, the entropy production and the degree of irreversibility of the system are linear with the logarithm of the CO2 concentration. The generalized sensitivities proposed here suggest that the climate system becomes less efficient, more irreversible, and features higher entropy production as it becomes warmer.
