Recently, Huang et al. (2002) have reported quasi-periodic fluctuations in all F region parameters (the electron density, and the ion density, temperature, and velocity) associated with solar wind variations in the IMF and dynamic pressure. The measurements were made using the Millstone Hill incoherent radar facility. It was suggested that the ionospheric response is due to a penetrating electric field. In this study we use the NRL ionosphere model SAMI2 to investigate this hypothesis. We impose an oscillatory electric field at the apex of the magnetic flux tubes that pass through the Millstone Hill radar beam. We find that SAMI2 produces results consistent with observations depending on the magnitude of the penetrating electric field. We provide estimates for the electric field and discuss other ionospheric implications of this study. \ Huang, C.-S., J.C. Foster, and P.J.
