Abstract
Experimental waveforms of natural ELF transient signals (Q-bursts) are compared with model computations. Vertical electric field component of Q-bursts was recorded at Tochi, Japan (33.3? N and 33.4? E) in 2003–2005. Separate pulses were chosen recoded in fair weather conditions in a wide frequency band with the help of the “ball” antenna. The computations were performed for the uniform isotropic spherical Earth – ionosphere cavity model with the linear frequency dependence of the wave propagation constant. Pulses arriving from different distances were compared, and each pair showed a high reciprocity of waveforms. Coincidence indicates that the model applied is correct; it simultaneously shows that distances are accurate found from the time delay between the first pulse and the antipodal wave.
KEY WORDS:Q-bursts, global electromagnetic resonance
