Low-frequency turbulence in electrostatic jumps with reference to Intercosmos-10 data
Abstract
Analysis of Intercosmos-10 data has revealed electric field bursts with amplitudes of up to 500 mV/m at altitudes 600-1400 km and latitudes less than 50 deg. These bursts, or electrostatic jumps, are accompanied by electric fields in the range 4-70 Hz. It is suggested that electrostatic jumps may be associated with VLF hiss and saucers. At peak gradients, the electrostatic jumps result in signals in the range 4-1000 Hz and changes in electron density and temperature. The Kelvin-Helmholtz instability is examined as one of the possible mechanisms involved in these effects.
