Field-aligned Currents in the Undisturbed Polar Ionosphere,o our understanding of plasma dynamics in the polar region and in the earth’s magnetosphere. Initial investigators of polar electrodynamics including the aurora were unable to distinguish between the ground magnetic signatures of a purely two-dimensional current and those from a three-dimensional cu

Modeling the Ionosphere Wind Dynamo: A Review,ul in reproducing the types of magnetic perturbations that are produced by the dynamo. Ionospheric electric fields are less well simulated, particularly at night. The primary areas of research needed to improve our ability to simulate realistically the ionospheric wind dynamo are in the modeling of

Contribution to Geomagnetic ,-Field and Equatorial Electrojet from the Day/Night Asymmetry of Ionospheric currents are much stronger on the dayside than on the nightside. These asymmetric currents over the earth produce a magnetic field detectable on the ground, which will contribute to a considerable extent to the .-field and equatorial electrojet.

The Equatorial Electrojet,titude are presented in terms of the corresponding variations of Δ. which is the deviation of the horizontal component (.) of the geomagnetic field from its steady nighttime level. The observed height structure of the current density in the EEJ as measured in rocket flights is presented, along with

Subsolar Elevation of the Equatorial Electrojet,h with the general style of the overhead equivalent current system. It shows the bunching of the current around the dip equator; the return currents of the equatorial electrojet close to the flanks of the dip equator; the fast growth of the electrojet to its diurnal peak followed by a slow decay; an
