In order to understand a disturbance field caused by a fast mode hydromagnetic wave (HM) during geomagnetic sudden commencements this paper examines the interaction of a plane HM wave propagated earthward from the noon magnetopause in the equatorial plane of the magnetosphere with a system composed of a conducting cylindrical earth and ionosphere. The magnetic fields above and below the ionosphere and the electric current and charge in the ionosphere are calculated at several local times. The ionospheric current is generally westward but a weak eastward current flows in the beginning stage of the rise of the incident magnetic field in the nighttime. The magnetic field is enhanced above the ionosphere and the enhancement rate is largest at noon. The magnetic field increase on the ground begins almost simultaneously, with nearly the same waveform and amplitude at any local time.
