Ionospheric currents and field-aligned currents generated by dynamo action in an asymmetric Earth magnetic field

[1] To investigate the influence of the magnetic field configuration on large-scale ionospheric electrodynamics, a geomagnetic field coordinate system based on Euler potentials is built for three magnetic field configurations: dipole, tilted dipole, and a revision of the International Geomagnetic Reference Field (IGRF). The two-dimensional ionospheric dynamo equation is expressed in this framew...

Magnetic field-aligned plasma currents in gravitational fields

Analytical models are presented for currents along vertical magnetic field lines due to slow bulk electron motion in plasmas subject to a gravitational force. It is demonstrated that a general feature of this problem is a singularity in the plasma pressure force that develops at some finite altitude when a plasma that is initially in static equilibrium is set into slow motion. Classical fluid m...

A Survey on Precision of Nested Water Level Data Derived From Delft3D Model

One of the troublesome aspects of numerical modeling is to determine open boundaries for a model and to make sure that the boundary conditions employed at the open boundaries are compatible with physical processes being simulated within the interior of the model domain. In this investigation the accuracy of the water level data derived from delft3D employing nesting procedure were studied. Thes...

Filamentary field-aligned currents at the polar cap region during northward interplanetary magnetic field derived with the Swarm constellation

ESA's Swarm constellation mission makes it possible for the first time to determine field-aligned currents (FACs) in the ionosphere uniquely. In particular at high latitudes, the dual-satellite approach can reliably detect some FAC structures which are missed by the traditional single-satellite technique. These FAC events occur preferentially poleward of the auroral oval and during times of nor...

Field - aligned currents during IMF 0

We report on field-aligned currents (FAC) obtained from precise magnetic field measurements made onboard the Orsted and Magsat satellites when the interplanetary magnetic field (IMF) was near zero. We found that Region 1/Region 2 currents persist through southward IMF, IMF -• 0, and northward IMF; also the central area of both the northern and southern polar caps is always filled with FACs, eve...
