Measuring low-current discharges from grounded rods under high background electric fields
Autor: Marcelo Arcanjo, Joan Montanyà, Michele Urbani, Victor Lorenzo
This work presents the development of an inductive current sensor for measuring pulsating corona discharges observed under high background electric field. Laboratory and field experiments in different setups are used to corroborate the discharge feat

Information about lightning activity and its parameters is necessary to design and evaluate the lightning protection of an electrical power system. This information can be obtained from ground-based lightning detection networks that provide informati

Upward propagation of gigantic jets revealed by 3D radio and optical mapping
Autor: Levi D. Boggs, Doug Mach, Eric Bruning, Ningyu Liu, Oscar A. van der Velde, Joan Montanyá, Steve Cummer, Kevin Palivec, Vanna Chmielewski, Don MacGorman, Michael Peterson
Occasionally, lightning will exit the top of a thunderstorm and connect to the lower edge of space, forming a gigantic jet. Here, we report on observations of a negative gigantic jet that transferred an extraordinary amount of charge between the trop

The study of electrical currents flowing through the airframe is very important from an EMC (Electromagnetic Compatibility) standpoint due to the potential to produce severe aircraft faults. As an example, direct lightning strikes are one of the main

Initial global extremes in lightning duration and horizontal distance were established in 2017 (Lang et al. 2017) by an international panel of atmospheric lightning scientists and engineers assembled by the WMO. The subsequent launch of NOAA’s late

In the same lightning flash, whose usual duration is less than a second, there can be multiple negative cloud-to-ground strokes with different terminations or following a preexisting channel to the ground. In contrast, it is not common to have multip
