内容記述 | The waveform measurements were carried out at two stations (Toyokawa and Kumamoto) in Aug. 1959, and their origins were located by our usual sferics fix network. Waveforms originated from the identical sources were observed by two separate but similar receivers. The majority of the couples of waveforms show the identical polarities of trains of pulses. But in two cases the exceptional couples of waveforms showing the reverse polarities independent of the orders of reflections, were found. As a vertical antenna is employed in our waveform observation, we cannot expect the reversed sign of waveform in propagation except for the evidence in oblique transmission. Hence a lightning discharge is assumed to be an intercloud one expressed by a horizontal electric dipole. Supposing the horizontal dipole was put on the origin of the Descartes rectangular coordinate and directed to the x-axis, the author derived the following expression for the received vertical electric field radiated from a horizontal dipole on a finitely conducting earth. As will be seen in the final form Ez = - 2k^2cosφ/n・e^jkr/r there shoul be a change of polarity with respect to the direction φ=π/2, where (The equation is omitted). | |||||
