In previous work, we have demonstrated the importance of atmospheric dynamics for determining the infrared spectra and light curves of close-in extrasolar giant planets (EGPs) (Showman & Guillot 2002, Cooper & Showman 2005, 2006; Fortney et al. 2006). Our past explorations focused on the transiting planet HD 209458b in particular. We expand our simulations here to encompass the whole class of close-in EGPs, including TrES-1 and HD 189733. These planets all orbit closely to their parent stars but vary in their sizes, orbital characteristics, stellar heating rates, and possibly CNO abundances. Vigorous meteorology on hot Jupiters is driven by strong heating from the stellar primary. We will present new simulations of the atmospheric dynamics on these planets using an improved treatment of the stellar heating, which is the key input into the dynamics model. We will perform multiple simulations with different physical inputs to explore the parameter space of close-in EGP meteorologies. Our studies will elucidate the significance of rotation rate (and other key physical properties) on the unknown meteorologies of these systems, with a view to interpreting near-future observations of these planets.
