Description
Just looking through a telescope from your backyard you can see that the planets from our own Solar-System have widely different atmospheres. Such a large diversity is also expected for exoplanets, particularly since they cover a much wider parameter space. Now that we are able to measure exoplanet atmospheric spectrum our goal is to separate the effects of intrinsic differences, such as elemental chemical composition, from differences due to their specific circumstances, such as their rotation period or their equilibrium temperature.
I will review how radiative transfer, atmospheric circulation, chemistry and microphysics shape giant planet atmospheres and discuss how these processes can produce very different outcomes in planets that only posses small differences. I will show the expected and observed patterns in the population both at low and high spectral resolution and discuss how these differ from our expectation.
