Description

The input and ouput simulation data of the THOR GCM for Dynamical and radiative effects resulting from the deep non-hydrostatic vs deep quasi-hydrostatic equations in the global circulation model THOR with an added non-grey radiative transfer scheme

Global circulation models (GCMs) play an important role in contemporary investigations of exoplanet atmospheres. Different GCMs evolve various sets of dynamical equations which can result in obtaining different atmospheric properties between models. In this study, we therefore investigate the effect of different dynamical equation sets on the atmosphere of hot Jupiter exoplanets. Therefore, we investigate effects in simulations of atmospheric dynamics and in the radiative transfer that different dynamical equations in GCMs produce. We compare GCM simulations by using the quasi-primitive dynamical equations (QHD) and the deep Navier-Stokes equations (NHD) in the GCM THOR. We utilise a two-stream non-grey "picket-fence" scheme to increase the realism of the radiative transfer scheme beyond the well-used semi-grey or Newtonian Cooling schemes used in previous similar studies. We performed GCM simulations of a grid covering wide parameter range of orbital elements in the population of exoplanets such planetary rotation rate, gravity and irradiation temperature at the top of the atmosphere. Our results show significant differences between simulations with the NHD and QHD at lower gravity, higher rotation rates or at higher irradiation temperatures after simulation duration of 5000 Earth days. Moreover, the two-stream non-grey "picket-fence" scheme lead to partially unexpected results due to more realistic radiative transfer. Overall, our study shows the importance of considering more realistic radiative transfer solutions and feedback when performing comparison exercises such as this. Finally, the study shows the relevance in the use of dynamical equation sets depending on planetary properties.
