[1] We examined data on 117 return strokes in 31 rocket‐and‐wire‐triggered lightning flashes acquired during experiments conducted from 1999 through 2004 at the International Center for Lightning Research and Testing at Camp Blanding, Florida, in order to compare the peak currents of the lightning return strokes with the corresponding charges transferred during various time intervals within 1 m...

This paper presents the preliminary results from CG lightning characteristics analysis over three large urban areas in southeastern Brazil: the São Paulo metropolitan area, Vale do Paraíba Paulista and the Campinas metropolitan area. A lightning dataset of about 310,000 flashes was obtained by the Brazilian lightning detection network during the months of December, January and February from 199...

The transmission lines are exposed to the atmosphere nature and will be affected by adverse weather such as lightning storm, so that it will affect the reliability of transmission system. This paper studies the fault probability model of transmission line during the lightning storm, and evaluates the short-term reliability of transmission system in the forecasting weather condition. Firstly, bu...

The North American Lightning Detection Network (NALDN) is a commercial lightning detection network composed of the U.S. National Lightning Detection Network (NLDN) and the Canadian Lightning Detection Network (CLDN). The NALDN was developed to provide lightning information by accurately detecting and locating most cloud-to-ground (CG) lightning strokes and a small fraction of discharges produce...

Electric power utilities face increasing demand for service reliability. Since cloud-toground lightning strikes are among the most frequent yet least understood causes of service interruption, predicting the geographical and temporal distribution of the lightning strikes can help power system planners and designers improve the protection of new and existing transmission lines. Lightning is the ...

The objective of the research reported here was to examine the epidemiologic characteristics of struck-by-lightning deaths. Using data from both the National Centers for Health Statistics (NCHS) multiple-cause-of-death tapes and the Census of Fatal Occupational Injuries (CFOI), which is maintained by the Bureau of Labor Statistics, the authors calculated numbers and annualized rates of lightnin...

Hotspot analysis was implemented to find regions in the province of Alberta (Canada) with high frequency Cloud to Ground (CG) lightning strikes clustered together. Generally, hotspot regions are located in the central, central east, and south central regions of the study region. About 94% of annual lightning occurred during warm months (June to August) and the daily lightning frequency was infl...

Multiple casualty incidents (MCIs) are uncommon in remote wilderness settings. This is a case report of a lightning strike on a Boy Scout troop hiking through Sequoia and Kings Canyon National Parks (SEKI), in which the lightning storm hindered rescue efforts. The purpose of this study was to review the response to a lightning-caused MCI in a wilderness setting, address lightning injury as it r...
