Phenomena associated with complex (dusty) plasmas in the ionosphere during high-speed meteor showers

Abstract

Formation of dusty plasmas in the Earth’s ionosphere at 80–120 km altitudes during high-speed meteor showers and its detectable manifestations are discussed. Emphasis is given to ground-based observations such as detection of low-frequency (<50 Hz) ionospheric radio noise, ground-based observations of infrasonic waves, and amplification of the intensity of green radiation at 557.7 nm from a layer at the 110–120 km altitude in the lower ionosphere. The physical processes responsible for these manifestations are considered.
