We describe a magnetohydrodynamic (MHD) simulation of Saturn's coupled magnetosphereionosphere- thermosphere system in which a vortical flow is assumed to be present near 70 degrees south latitude in a rotating ionosphere-thermosphere. We find that the magnetosphere's response to this simple assumption regarding driving conditions produces the periodic magnetospheric phenomena that have been reported. We propose that the essence of our model is supported by powerful, albeit indirect, evidence of its validity and that more direct evidence of flow structures in the upper atmosphere should be sought.
