1. Coupled Electron-Plasma and Ion-Acoustic Solitons Excited by Parametric Instability

Abstract

Self-modulation of the high-frequency electric field is observed when its frequency is near the electron plasma frequency. The localized field due to the self-modulation is found to make deprossions in the plasma density, and to be trapped in the deniiity dip which moves with the ion-acoustic speed. The depth of the dip reaches to 20% of the unperturbed density. The maximum amplitudes of the high-frequency field and the density dip are linearly proportional to each other. All these features are quantitatively explained by the results of the theory of coupled electron-plasma and ion-acoustic solitary waves.

2. Reduction of Topside Ionograms for Field-aligned Propagation Paths

Abstract

FIELD-ALIGNED reflexion traces are one of the common features of topside sounder ionograms when the sounder height is large (> 1,000 km) at mid and low latitudes and they usually have greater ranges, at a given frequency, than the vertical incidence reflexion traces. They are considered to be caused by the propagation of radio waves along field-aligned ionization ducts in the topside ionosphere or exosphere1,2.
