| Zusammenfassung |
| The problem of boundary conditions for
monochromatic Alfvén waves, excited in the magnetosphere by external currents
in the ionospheric E-layer, is solved analytically. Waves with large azimuthal
wave numbers m»1 are considered. In our calculations, we used a model
for the horizontally homogeneous ionosphere with an arbitrary inclination of
geomagnetic field lines and a realistic height disribution of Alfvén velocity
and conductivity tensor components. A relationship between such Alfvén waves on
the upper ionospheric boundary with electromagnetic oscillations on the ground
was detected, and the spatial structure of these oscillations determined. |
