The Propagation Effects of Lightning Electromagnetic Fields Over Mountainous Terrain in the Earth-Ionosphere Waveguide

Farhad Rachidi-Haeri, Marcos Rubinstein, Mohammad Azadifar, Dongshuai Li

In this paper, a full-wave two-dimensional Finite-Difference-Time-Domain model is developed to evaluate the propagation effects of lightning electromagnetic fields over mountainous terrain in the Earth-ionosphere waveguide. In the model, we investigate the ...

Pulses in Upward Negative Lightning at the Säntis Tower in Northeastern Switzerland

Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Davide Pavanello, Lixia He

Upward lightning happens predominantly from tall objects. The channel-base currents associated with upward negative lightning initiated from towers exhibit pulses that can be classified, based on their waveform features and on the concurrence with other pr ...

Two Possible Scenarios for the Formation of Category 1 Bipolar Lightning Flashes

Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello, Qi Li

We present and discuss the current and electric field waveforms associated with two upward bipolar lightning flashes that occurred at the Säntis Tower. According to the traditional classification of bipolar flashes, both observed flashes could be classifie ...

An Analysis of Current and Electric Field Pulses Associated With Upward Negative Lightning Flashes Initiated from the Säntis Tower

Marcos Rubinstein, Lixia He, Mohammad Azadifar, Davide Pavanello

We present a study on the characteristics of current and electric field pulses associated with upward lightning flashes initiated from the instrumented Säntis Tower in Switzerland. The electric field was measured 15 km from the tower. Upward flashes always ...
