| Summary: | A review is presented of the effects
influencing the ionosphere which are caused by acoustic emission from different
sources (chemical and nuclear explosions, bolides, meteorites, earthquakes,
volcanic eruptions, hurricanes, launches of spacecrafts and flights of
supersonic jets). A terse statement is given of the basic theoretical principles
and simplified theoretical models underlying the physics of propagation of
infrasonic pulses and gravity waves in the upper atmosphere. The observations of
"quick" response by the ionosphere are pointed out. The problem of
magnetic disturbances and magnetohydrodynamic (MHD) wave generation in the
ionosphere is investigated. In particular, the supersonic propagation of
ionospheric disturbances, and the conversion of the acoustic energy into the
so-called gyrotropic waves in the ionospheric E-layer are considered. |
