| Zusammenfassung |
| In this work, the many-fluid magnetohydrodynamic theory is applied to describe the
modification of the electromagnetic field of the ionospheric E-layer by
acoustic-type waves. There, altitudinal profiles of the electromagnetic
field and
the plasma parameters of the atmosphere and ionosphere are taken into
account. It is concluded that at E-region altitudes
above seismo-active regions, magnetohydrodynamic waves as
Alfvén and magnetoacoustic ones might change their amplitude and
direction of propagation. Waves of the Farley-Buneman type might also be
excited a few
days before very strong earthquakes. The collisions between the neutral and
charged particles of the E-layer also cause diffusion and heating
processes. Thus, changes of the characteristic foE-frequency might be
obtained. |
