| Zusammenfassung |
| Physical processes which affect the
absorption of radio waves passing through the auroral E-region when Farley-Buneman
irregularities are present are examined. In particular, the question of whether
or not it is legitimate to include the anomalous wave-enhanced collision
frequency, which has been used successfully to account for the heating effects
of Farley-Buneman waves in the auroral E-region, in the usual expression for the
radio-wave absorption coefficient is addressed. Effects also considered are
those due to wave coupling between electromagnetic waves and high-frequency
electrostatic waves in the presence of Farley-Buneman irregularities. The
implications for radio-wave heating of the auroral electrojet of these processes
are also discussed. In particular, a new theoretical model for calculating the
effects of high-power radio-wave heating on the electron temperature in an
electrojet containing Farley-Buneman turbulence is presented. |
