Enhancement of Cloud-to-Ground Lightning Activity Caused by the Urban Effect: A Case Study in the Beijing Metropolitan Area

Remote Sensing, 2021
To investigate the possible impact of urban development on lightning activity, an eight-year (2010–2017) cloud-to-ground (CG) lightning dataset provided by the National-Wide Lightning Detection Network in China was analyzed to characterize the CG ...

Lightning activity following the return stroke [PDF]

Journal of Geophysical Research: Atmospheres, 2014
Natural lightning is both frequent and variable and thus a good subject for statistical studies. A typical negative cloud-to-ground (CG) flash consists of multiple individual return strokes. The spatial and temporal distributions of various lightning events throughout the discharge provide a surrogate look inside the CG flash and offer insight into the

A fractal model for the lightning induced current on a transmission line [PDF]

, 1997
This article presents a model of a tortuous lightning channel, and a study of the consequent electromagnetic coupling to a transmission line. We analyse the fractal dimension of the induced current on the line, compared with the fractal dimension of the ...

Global distribution of winter lightning: a threat to wind turbines and aircraft [PDF]

Natural Hazards and Earth System Sciences, 2016
Lightning is one of the major threats to multi-megawatt wind turbines and a concern for modern aircraft due to the use of lightweight composite materials. Both wind turbines and aircraft can initiate lightning, and very favorable conditions for lightning

Activity characteristics of the cloud-to-ground lightning in a severe convective weather event in Arksu of Xinjiang

暴雨灾害, 2022
A severe convective weather event occurred in the Arksu area of Xinjiang on 7 June 2017. In this event, two α-mesoscale convection systems (MCS) and their merging and development caused gale, hailstorm, and short-time heavy precipitation at several ...

Area‐average rainfall and lightning activity [PDF]

Journal of Geophysical Research: Atmospheres, 1997
The aim of the paper is to discuss the statistical relations between the average rainfall parameters for an ensemble of convective cells and the mean lightning occurrence inside this area. The study is based on a data set gathered in France using C and S band radars and two different lightning detection networks.

"Statistics and dynamics of the lightning activity over Belgium"

, 2021
The statistical and dynamical properties of the lightning activity over Belgium are investigated for time scales ranging from 5 minutes up to a few hours by means of tools developed in nonldinear dynamics. Two main regimes, for short and long timescales,

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

Advanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.
