In today's journal club, we reviewed Showman et al. (2014) "Three-dimensional Atmospheric Circulation of Warm and Hot Jupiters: Effects of Orbital Distance, Rotation Period, and Non-Synchronous Rotation. By simple timescale analysis of comparing the radiative time and solar day, the circulations are divided into two regimes: high irradiation and slow rotation regime exhibits equatorial superrotating jet, while lower irradiation and faster rotation results in larger latitudinal temperature gradient and off-equatorial eastward jets. 3D numerical simulations using the SPARC/MITgcm show agreement with the theoretical predictions.
