SUMMARY:Exonephology: 3D simulations of cloud formation and evolution in h
 ot Jupiter atmospheres. - Stefan Lines (Exeter)

DESCRIPTION:Evidence of clouds in hot-Jupiter atmospheres spans from varia
 bility of and offsets in planetary phase curves\, to muted absorption feat
 ures in transmission spectra. The latter can be attributed to the opaque n
 ature of cloud condensate decks and/or haze\, and presents challenges for 
 atmospheric characterisation. To further explore the role condensate cloud
 s play in these extreme environments\, we couple to the UK Met Office’s 
 General Circulation Model both a microphysical and a simple parameterised 
 cloud formation scheme to investigate cloud formation\, structure\, compos
 ition and evolution across cloud modelling paradigms. In this talk\, I wil
 l focus on the importance of including cloud radiative feedback for obtain
 ing the true atmospheric thermal structure\, and I present transmission an
 d emission spectra\, albedos and phase curves from our 3D radiatively acti
 ve simulations of HD 209458b.
