在浅大气近似中适用于太阳系外气体巨行星的全球气候模式的基准试验

Benchmark experiments with global climate models applicable to extra-solar gas giant planets in the shallow atmosphere approximation

V. L. Bending, S. R. Lewis, U. Kolb

摘要:

外行星大气建模领域的不断发展,几乎没有对其模型进行标准化基准测试的工作,限制了对结果对特定模型和条件的依赖性的理解。由于空间分辨观测还很难获得,这样的测试是非常宝贵的。虽然以前曾建议并进行过潮汐锁定气体巨行星模型的相互比较测试,但所提供的数据在可比性方面有限。在这里,浅层的ARMA模型进行这样的测试,并产生详细的统计数据,以方便比较,时间平均值和相关的标准偏差显示,消除时间依赖性,并提供一个可变性的措施。模型运行进行了分析,以确定分辨率之间的变异性,以及分辨率对研究的能谱的影响。超旋转在所有分辨率下都是一种稳健且可重现的特征。

英文摘要:

The growing field of exoplanetary atmospheric modelling has seen little work on standardised benchmark tests for its models, limiting understanding of the dependence of results on specific models and conditions. With spatially resolved observations as yet difficult to obtain, such a test is invaluable. Although an intercomparison test for models of tidally locked gas giant planets has previously been suggested and carried out, the data provided were limited in terms of comparability. Here, the shallow PUMA model is subjected to such a test, and detailed statistics produced to facilitate comparison, with both time means and the associated standard deviations displayed, removing the time dependence and providing a measure of the variability. Model runs have been analysed to determine the variability between resolutions, and the effect of resolution on the energy spectra studied. Superrotation is a robust and reproducible feature at all resolutions.
