AB: Models for the field-aligned currents and electric potential drops in the magnetosphere are presented on the basis of observational data, and are introduced in the upgraded Prairie View Dynamo Code, by adding extra field- aligned current term and potential drop term into the Poisson equation. The effects of the field-aligned currents and potential drops on the coupling of the ionosphere with the magnetosphere are examined under different solar wind and geomagnetic conditions for different dates and diurnal times.
