Scientific paper

We present first results from a newly developed numerical model for ULF wave propagation in the magnetosphere-ionosphere coupled system. This model is cast in a non-orthogonal dipole coordinate system, and includes a realistic distribution of ionospheric Pedersen, Hall and parallel conductivities. Coupling through the atmosphere to the ground is accomplished by the solution to an elliptic equation for the magnetic scalar potential so that the ground and space signatures of ULF waves can be determined. This model has been used to study shear Alfvén waves trapped in the ionospheric Alfvén resonator and their coupling to compressional modes by the Hall conductivity in the ionosphere. Results show that the presence of the distributed conductivities does not strongly affect the resonant frequencies of the resonator, but does generally lead to greater damping of these modes compared with a model with the same height-integrated conductivity confined to a boundary slab.
