A numerical simulation study of the ultra-low frequency (ULF) H-component magnetic field at the Earth's surface arising from a perturbation ionospheric Hall current has been developed. The Hall current system is driven by field-aligned currents (FACs) associated with shear Alfven field line resonances (FLRs) driven by fast mode global cavity oscillations. The ionospheric phase mixing of the Hall current manifests itself in a number of ways in the ground field, these are: (1) Smoothing the spectral maxima of the ground signal: (2) Loss in clarity of the harmonic structure of the spectra: (3) A small increase in the damping rate of the ULF wave at the resonance latitude and (4) small localised minimum in the spectra at the resonance latitude.
