Laser-guided lightning [PDF]

open access: yesNature Photonics, 2022
A terawatt laser filament is shown to be able to guide lightning over a distance of 50 m in field trials on the Säntis mountain in the Swiss Alps. Lightning discharges between charged clouds and the Earth’s surface are responsible for considerable ...

Risk zoning of lightning disaster in Hubei Province based on improved analytic hierarchy process

open access: yes暴雨灾害, 2023
Determining accurately the relative importance of evaluation indicators is one of the key technologies for lightning disaster risk zoning. In order to solve the problem of analytic hierarchy process (AHP) in judging the relative importance of indices by ...

Variation of lightning-ignited wildfire patterns under climate change

open access: yesNature Communications, 2023
Lightning is the main precursor of natural wildfires and Long-Continuing-Current (LCC) lightning flashes are proposed to be the main igniters of lightning-ignited wildfires (LIW).

Comparative analysis of cloud-ground flash data of two lightning location networks in Hubei Province

open access: yes暴雨灾害, 2021
Based on location mode, current intensity and clustering standard, quality control is carried on the lightning stroke data of ADTD two dimensional lightning location network (2D-LLN) and VLF/LF three dimensional lightning location network (3D-LLN) in ...

Future increases in lightning ignition efficiency and wildfire occurrence expected from drier fuels in boreal forest ecosystems of western North America

open access: yesEnvironmental Research Letters, 2022
Lightning-induced fire is the primary disturbance agent in boreal forests. Recent large fire years have been linked to anomalously high numbers of lightning-caused fire starts, yet the mechanisms regulating the probability of lightning ignition remain ...

Application of Statistical Distribution Models to Predict Health Index for Condition-Based Management of Transformers

open access: yesApplied Sciences, 2021
In this study, statistical distribution model (SDM) is used to predict the health index (HI) of transformers by utilizing the condition parameters data from dissolved gas analysis (DGA), oil quality analysis (OQA), and furanic compound analysis (FCA ...

Exploring Perceptions of Control Within Offender Cognition and Recidivism Paradigms

open access: yesEurope's Journal of Psychology, 2022
Elements of perceived control are associated with recidivism in offender populations. We investigated the application of locus of control to the frequency of personal involvement with the law and to beliefs surrounding the likelihood of future contact ...

Lightning threats in Nepal: occurrence and human impacts

open access: yesGeomatics, Natural Hazards & Risk, 2022
Nepal has a very large topographical variation; this elevation change has a major influence on lightning occurrence and human casualties. The Himalayan peaks cover the northern part of Nepal with low population density, the middle is covered by hills ...

Lightning strike probability and current simulation for simple structures and floating roof tank

open access: yesAlexandria Engineering Journal, 2022
Air terminations must be strategically positioned at high-risk points to prevent lightning bypass. The likelihood of a direct lightning strike to points on a building can be evaluated using the dynamic electro-geometrical model (DEGM), which considers ...
