On ELF pulses from remote lightnings triggering sprites



ELF waveforms at large distances from strong CG (cloud-to-ground) discharges are evaluated in the framework of Greifinger's night-time propagation model. It is shown that if the CG discharges triggering red sprites involve, as now generally accepted, ≳10² C of charge, then they should generate remote ELF atmospherics with considerably larger magnitudes than measured in the upper ELF (> 300 Hz) range.
