This paper presents a physical model explaining how high-power HF waves can generate ionizing wavefronts in the ionosphere through electron acceleration and plasma turbulence, based on recent HAARP experiments.

Contribution

It introduces a novel physical model of ionizing wavefronts created by HF-induced plasma turbulence and electron acceleration, advancing understanding of ionospheric modification mechanisms.

Findings

Artificial ionization descending from the F-region observed at HAARP.

Model explains ionization via suprathermal electron acceleration.

Provides a physical basis for ionospheric modification phenomena.

Abstract

Recent ionospheric modification experiments with the 3.6 MW transmitter at the High Frequency Active Auroral Research Program (HAARP) facility in Alaska led to discovery of artificial ionization descending from the nominal interaction altitude in the background F-region ionosphere by ~60 km. This paper presents a physical model of an ionizing wavefront created by suprathermal electrons accelerated by the HF-excited plasma turbulence.
