| description | In this paper we develop a new method for the analysis of excitation and
propagation of planetary electromagnetic waves (PEMW) in the ionosphere of
the Earth. The nonlinear system of equations for PEMW, valid for any height,
from D to F regions, including intermediate altitudes between D and E and
between E and F regions, is derived. In particular, we have found the system
of nonlinear one-fluid MHD equations in the β-plane approximation valid
for the ionospheric F region (Aburjania et al., 2003a, 2005). The
series expansion in a "small" (relative to the local geomagnetic field)
non-stationary magnetic field has been applied only at the last step of the
derivation of the equations. The small mechanical vertical displacement of
the media is taken into account. We have shown that obtained equations can be
reduced to the well-known system with Larichev–Reznik vortex solution in the
equatorial region (see e.g. Aburjania et al., 2002). The excitation of
planetary electromagnetic waves by different initial perturbations has been
investigated numerically. Some means for the PEMW detection and data
processing are discussed. |
