AMPLITUDE STATISTICS OF LIGHTNING DISCHARGE CURRENTS AND ELF AND VLF RADIO NOISE.
Abstract
The received noise is considered as the result of integrating several atmospherics during the response time of the receiver. The probability distributions of this noise, and of current in lightning flashes are related by a twofold Hankel transform. The derived current for very large amplitudes. This characteristic has been used to extend measured lightning statistics to larger amplitudes. The resulting received noise is characterized by a Rayleigh distribution for small signals, and the distribution is inversely proportional to the squared amplitudes for large signals. The present calculations provide amplitude distributions of the received noise which approximate measured noise characteristics more closely than in earlier work, which was based on the approximation of measured current distributions by two exponentials.
