Advances of Observation and Study on Tall-object Lightning in Guangzhou over the Last Decade

应用气象学报, 2020
Comparing to the ground or low-object, tall-object is more likely to reach the threshold for the initiation of leader on its top due to the distortion and enhancement of electric field, therefore tall-object is not only easier to get struck by downward ...

Determining the size of lightning-induced electron precipitation patches

, 2002
[1] We analyze Trimpi signatures during 23 and 24 April 1994 at four sites on or near the Antarctic Peninsula (Palmer, Faraday, Rothera, and Halley) on subionospheric VLF signals received from four U. S.

Application of a Modified Empirical Wavelet Transform Method in VLF/LF Lightning Electric Field Signals

Remote Sensing, 2022
In this paper, to realize a better adaptive method for the lightning electric field signal denoising, we firstly compared the decomposition results of three methods called the EMD (empirical mode decomposition), the CEEMDAN (complete ensemble empirical ...

Telescope Array Lightning Location System [PDF]

Proceedings of 35th International Cosmic Ray Conference — PoS(ICRC2017), 2017
The Telescope Array (TA) experiment detects air-showers induced by ultra high energy cosmic rays. The TA ground Surface particle Detector array (TASD) observed some short-duration bursts of air-shower like events. As reported at ICRC2015, these events are evidently correlated with lightning. Therefore, we have deployed detectors for lightning discharge

GIS enabled thunderstorm forecasting system for one of the world’s hotspot region for severe thunderstorms [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The eastern parts of India, Bangladesh, and the North Eastern Region (NER) of India are among the world's most active areas for thunderstorms and lightning, resulting in substantial human and livestock casualties annually.

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.
