Lightning detection and lightning protection of power systems in Japan

IEEE/PES Transmission and Distribution Conference and Exhibition, 2003
Lightning occurrence data have been collected with the lightning location systems operated by electric power companies in Japan. Seasonal variations and annual variations of lightning occurrence have been clarified from the seasonal and annual lightning stroke frequency maps made by the above data.

Revisiting the Detection of Lightning Superbolts

2020
This study uses Fast On-Orbit Detection of Transient Events (FORTE) satellite observations to identify superbolt-class optical lightning events and evaluate their origins.

Optical and Acoustic Detection of Ball Lightning

Nature, 1971
THE recent controversy about ball lightning1–4 stimulates me to report an observation of such an event, which occurred in September 1963.

An East Coast Lightning Detection Network

Bulletin of the American Meteorological Society, 1983
Abstract A magnetic direction-finding network for the detection of lightning cloud-to-ground strikes has been installed, and it records most of the ground flashes from Maine to North Carolina and as far west as Ohio. This area includes or touches fourteen states and contains over a quarter of the population of the United States.

High-Precision Lightning Detection in Thailand

2019 IEEE PES GTD Grand International Conference and Exposition Asia (GTD Asia), 2019
In recent years a modern lightning detection network has been installed all over Thailand. It is a LINET system that exploits the VLF/LF frequency regime and works with the precise TOA technique. Detection efficiency, location accuracy, and 3D reporting of cloud strokes are provided at a high quality level. Application tools have been implemented, such

Comparison of location accuracy of the Japanese lightning detection network with large scale lightning detection networks

International Conference on Lightning [amp ] Static Electricity (ICOLSE 2015), 2015
The Japanese Lightning Detection Network (JLDN) has been operated to observed lightning occurring in Japan and its surrounding areas since 1998. The frequency of lightning flash is an important parameter for creating lightning protection designs. If the location accuracy of the Lightning Location System (LLS) is not good, it is very difficult to ...

LINET—An international lightning detection network in Europe

Atmospheric Research, 2009
Abstract During the past years a VLF/LF lightning detection network (LINET) was developed at the University of Munich, which provides continuous data for both research and operational purposes. In particular, the network introduces five new features: a) total lightning capability: both cloud-to-ground strokes (CG) and cloud lightning (IC) are ...

LAMPINET – Lightning Detection in Italy

2008
In 2004 the Italian Air Force Meteorological Service has set up a modern lightning detection network, LAMPINET, in order to monitor comprehensively atmospheric discharges. The requirements arose from the fact that lightning still represents a severe threat for both military and commercial aircraft; despite continuous improvement of aircraft materials ...

Positive Lightning Peak Currents Reported by the U.S. National Lightning Detection Network

IEEE Transactions on Electromagnetic Compatibility, 2014
We infer peak currents from radiation electric field peaks of 48 positive return strokes acquired in Gainesville, FL, USA, from 2007 to 2008. In doing so, we use the transmission line model, National Lightning Detection Network (NLDN) -reported distances, and assumed return-stroke speed.

Visualizing the geometry of lightning detected by MTG’s Lightning Imager

The Lightning Imager (LI) instrument aboard the first Meteosat Third Generation (MTG) satellite provides valuable data for detecting and monitoring convective storms by capturing localized pulses of visible light emitted by lightning. These detections have a spatial resolution of approximately 10 km and occur at a high temporal resolution of 1 kHz, or ...
