The number of planets detected outside of our solar system has increased at an almost exponential rate over the past 10 years with currently more than 1800 confirmed exoplanets. Slowly, we are beginning to characterize the physical properties of these planets including their atmospheric composition, thermal structure, and global circulation patterns. Here I discuss the combination of sophisticated three-dimensional atmospheric models with space-based observations to probe weather patterns in exoplanet atmospheres. I will focus on recent phase-curve and eclipse-mapping observations with the Spitzer Space Telescope aimed at characterizing the global circulation patterns of extrasolar planets. The combination of these observations with atmospheric models will hopefully shed new light on the radiative, dynamic, and chemical process that are at work in these atmospheres beyond our solar system.
