Inductive magnetosphere–ionosphere coupling
Inductive coupling of a global magnetospheric model to a global ionospheric–thermospheric model is described. Existing schemes based on electrostatic coupling are valid for magnetospheric variability occurring on time scales of order 100 s or longer. The formulation developed here extends the validity of the coupling model to time scales of order 10 s, while retaining the physics of quasi-stati...
متن کاملMagnetosphere-Ionosphere Coupling by Alfvén Waves: Beyond Current Continuity
Many numerical models of magnetospheric dynamics treat the ionosphere as an inner boundary condition. These models have traditionally used the current continuity condition, treating the ionosphere as a sheet current in which the electric field is electrostatic. A more general boundary condition is suggested that not only is more complete, but also straightforward to implement. Results from a mo...
متن کاملA statistical study of magnetosphere–ionosphere coupling in the Lyon–Fedder–Mobarry global MHD model
The statistics of magnetosphere–ionosphere (MI) coupling derived from a two-month long run of the Lyon–Fedder–Mobarry (LFM) global simulation model are investigated. MI coupling characteristics such as polar cap potential and field-aligned current (FAC), downward Poynting flux and vorticity of ionospheric convection are compared with observed statistical averages and with results from the Weime...
متن کاملMagnetosphere-ionosphere coupling currents in Jupiter’s middle magnetosphere: effect of magnetosphere-ionosphere decoupling by field-aligned auroral voltages
We consider the effect of field-aligned voltages on the magnetosphere-ionosphere coupling current system associated with the breakdown of rigid corotation of equatorial plasma in Jupiter’s middle magnetosphere. Previous analyses have assumed perfect mapping of the electric field and flow along equipotential field lines between the equatorial plane and the ionosphere, whereas it has been shown t...
متن کاملUse of Euler potentials for describing magnetosphere-ionosphere coupling
[1] We present a general formulation of the basic equations of large-scale magnetosphereionosphere coupling in terms of Euler potentials and describe a specific numerical implementation of this formulation in the context of the Rice Convection Model (RCM). When written in terms of Euler potentials, both the Vasyliunas magnetosphere-ionosphere coupling equation and the expression for bounce-aver...
