Radiative equilibrium temperatures are calculated for the troposphere of a tidally locked Super-Earth based on a simple greenhouse model , using Solar System data as a guideline .
These temperatures provide in combination with a Newtonian relaxation scheme thermal forcing for a 3D atmosphere model using the dynamical core of the Massachusetts Institute of Technology global circulation model ( MITgcm ) .
Our model is of the same conceptional simplicity than the model of and is thus computationally fast .
Furthermore , because of the coherent , general derivation of radiative equilibrium temperatures , our model is easily adaptable for different planets and atmospheric scenarios .
As a case study relevant for Super-Earths , we investigate a Gl581g-like planet with Earth-like atmosphere and irradiation and present results for two representative rotation periods of P _ { rot } = 10 days and P _ { rot } = 36.5 days .
Our results provide proof of concept and highlight interesting dynamical features for the rotating regime 3 < P _ { rot } < 100 days , which was shown by ( ) to be an intermediate regime between equatorial superrotation and divergence .
We confirm that the P _ { rot } = 10 days case is more dominated by equatorial superrotation dynamics than the P _ { rot } = 36.5 days case , which shows diminishing influence of standing Rossby-Kelvin waves and increasing influence of divergence at the top of the atmosphere .
We argue that this dynamical regime change relates to the increase in Rossby deformation radius , in agreement with previous studies .
However , we also pay attention to other features that are not or only in partial agreement with other studies , like , e.g. , the number of circulation cells and their strength , the role and extent of thermal inversion layers , and the details of heat transport .
