Abstract

The background of VLF wave-particle experiments from Siple Station, Antarctica, including wave-induced precipitation is briefly reviewed. Single frequency ducted signals that exceed a certain \u27threshold\u27 intensity are observed at the conjugate point (Roberval, Quebec) to be amplified 30-50dB, with temporal growth rates of 30-200dB/s. Following saturation, variable frequency emissions are triggered. When a second signal is added to the first, with a frequency spacing Df<100Hz, signal growth is reduced and sidebands are generated at frequencies separated from the carriers by integer multiples (up to seven) of Df. The sidebands are attributed to short emissions triggered by the beats between the two input carriers. Mid-latitude magnetosp...
