In this study, ball lightning (BL) is assumed to have a solid, positively-charged core. According to this underlying assumption, the core is surrounded by a thin electron layer with a charge nearly equal in magnitude to that of the core. A vacuum

Cases of mesoscale cloud bands in extratropical cyclones are observed a few hours after atmospheric gravity waves (AGWs) are launched from the auroral ionosphere. It is suggested that the solar-wind-generated auroral AGWs contribute to processes t

A case study of medium-scale travelling ionospheric disturbances (TIDs) that are correlated with solar wind Alfvén waves is presented. The HF radar ground-scatter signatures of TIDs caused by atmospheric gravity waves with periods of 20-40min are

Evidence is presented for the radiation of an electron Bernstein wave from a radio frequency pulse simulated by proton-cyclotron motion. The protons are energized by an ionospheric topside sounder transmitter pulse and take part in a plasma memory pr

For propagation in the magnetic meridian plane at two particular angles of incidence near the vertical, the ordinary (O) electromagnetic mode couples into what Budden [1961] calls the extraordinary (X) mode and what more recently has been called the

[1] Lewis and Keller (1962) derive the dispersion relation for homogeneous waves propagating in a hot magnetoplasma. Homogeneous waves are ones for which the real and imaginary parts of the wave vector, kr and ki, are parallel. In this paper a genera

Recent high-resolution height observations of the HF-induced plasma line have been made by Djuth et al. [1990]. The plasma line is first observed after 3 ms very close to the HF-reflection height and not at the height expected from weak-turbulence th

The plasma-line spectrum observed during on-off cycling of the HF heater at Arecibo contains a broad component extending about 50 kHz from the first decay line. Shortly after HF turn-on this spectrum can have a maximum intensity 10–20 kHz from the

Ball lightning (BL) is mathematically modelled assuming a solid, positively charged core exists at its center. The large amount of energy occasionally associated with BL is mainly due to the electrostatic (ES) energy of the charge on the core. The up
