Non-direct lightning current measurement for lightning location systems calibration
Electronics Letters, 2003 An alternative approach for calibration of lightning location systems is proposed. The basis of the method is a new electronic device that performs non-direct measurement and register of lightning current parameters, including waveshape and instant of occurrence. Circuit diagrams and the device operation are described.

Modeling lightning strikes to tall towers
In this chapter, we present a review of recent progress in the modeling of lightning strikes to tall structures. Since some tall structures are struck by lightning several tens of times per year, they can be used as ground-truth to measure and calibrate ...

Lightning Impulse Ageing of HDPE
, 2009 This work is concerned with the hypothesis that lightning impulses can lead to accelerated ageing of extruded polymeric cables. The behaviour of an insulation material when suffering lightning impulses is different from that for DC or power frequency ...

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy
International Journal of Climatology, EarlyView.This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...
