FlashBench: A lightning nowcasting framework based on the hybrid deep learning and physics-based dynamical models [PDF]
arXiv, 2023 Lightning strikes are a well-known danger, and are a leading cause of accidental fatality worldwide. Unfortunately, lightning hazards seldom make headlines in international media coverage because of their infrequency and the low number of casualties each incidence.

Analysis of transient overvoltages in EV charging stations due to direct lightning strikes
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This research investigates the impact of lightning on electric vehicle charging stations (EVCSs), focusing on the critical role of grounding systems. By simulating various lightning strike scenarios, we examine the influence of factors such as grounding configuration, cable shielding, and lightning current characteristics on the induced overvoltages ...

Discharge image reconstruction and frequency domain analysis based on event data
High Voltage, Volume 9, Issue 6, Page 1195-1201, December 2024.Abstract Optical image method has been the earliest and most used direct method for observing gas discharge. Currently, research on gas discharge monitoring based on visible light mainly relies on high‐speed cameras, but the large size, significant data storage requirements, and susceptibility to interference from complex backgrounds and lighting ...

A possible relationship between Global Warming and Lightning Activity in India during the period 1998-2009 [PDF]
arXiv, 2010 Lightning activity on a global scale has been studied season wise using satellite data for the period from 1998 to 2009. Lightning activity shows an increasing trend during the period of study which is highly correlated with atmospheric warming. A similar increasing trend of lightning activity is observed in the Indian region during the pre-monsoon ...
