Wind maps (arrows) at the 200 mb pressure level (top panel) and near the surface (900 mb pressure level; bottom panel) for Gl 581 c, Gl 581 c with a slower rotation (see text), and HD 85512 b (from left to right, respectively). The mean surface pressure is 1 b for all the models. Color scale (same for all panels) and numbers show the wind speed in m/s. Air is converging toward the substellar point at low altitudes in all models. However, whereas the standard Gl 581 c case clearly exhibits eastward jets (super-rotation) at higher altitudes, both slowly rotating cases tend to have stellar/anti stellar winds at the same level.
