Characteristics of Upward Lightning Flashes

Mohammad Azadifar

In addition to the general aims of lightning research such as lightning physics and meteorology, the study of upward lightning is of particular importance in protection of tall objects such as wind turbines and telecommunication towers. It also helps us in ...

Analysis of lightning-ionosphere interaction using simultaneous records of source current and 380 km distant electric field

Mario Paolone, Marcos Rubinstein, Mohammad Azadifar, Wolfgang Schulz, Davide Pavanello, Dongshuai Li

We present simultaneous current and wideband electric field waveforms at 380 km associated with upward lightning flashes initiated from the Santis Tower, Switzerland. To the best of our knowledge, the dataset presented in this study includes the first simu ...

Determination of the centre of mass kinematics in alpine skiing using differential global navigation satellite systems

Julien Chardonnens

In the sport of alpine skiing, knowledge about the centre of mass (CoM) kinematics (i.e. position, velocity and acceleration) is essential to better understand both performance and injury. This study proposes a global navigation satellite system (GNSS)-bas ...

Electromagnetic Fields of a Lightning Return Stroke in Presence of a Stratified Ground

Marcos Rubinstein, Abdenabi Mimouni

We present an analysis of the nearby electromagnetic fields generated by lightning discharges in the presence of a horizontally stratified, two-layer ground. To the best of our knowledge, this is the first time the effect of ground stratification on underg ...

On the Location of Lightning Discharges Using Time Reversal of Electromagnetic Fields

Marcos Rubinstein, Nicolas Mora Parra, Gaspard Lugrin

In this paper, we discuss the use of the electromagnetic time reversal (EMTR) method to locate lightning strikes. After a brief description of the EMTR and its application to lightning location, we mathematically demonstrate that the time-of-arrival method ...
