Аннотация:
To numerically simulate large-scale electric fields in the magnetosphere and ionosphere, the electrical
conductivity problem is solved. The problem is substantially simplified due to the presence of a small
parameter, the ratio of the conductivities in directions perpendicular and parallel to the magnetic field. Setting
this parameter equal to zero makes magnetic field lines equipotential, so that the original three-dimensional
problem reduces to a two-dimensional one. A comparison with the results of calculations performed
within the framework of an alternative thin-layer model clearly demonstrates the advantages of using the conductivity
anisotropy tensor rather than the smallness of the thickness of the ionosphere for constructing a
two-dimensional approximation in a global simulation including the low-latitude ionosphere.
