Atrial fibrillation (AF) is a common arrhythmia that occurs in paroxysmal and persistent forms. It occurs in varied situations but lightning induced AF is extremely rare. Here is a case which reverted to sinus rhythm spontaneously. This 37-year-old man without any underlying heart disease had new onset AF after being struck by a lightning. Oral Metoprolol alone was given to control ventricular ...
Lightning injury is the second most common cause of weather-related deaths in the United States. Despite the several neurological complications such as polyneuropathy, myelopathy, spinal cord injury, motor neuron disease due to the lightning-induced injury, there is no documented case of unilateral diaphragmatic paralysis. We describe the case of a patient with a history of lightning strike at ...
A new lightning detection network (LINET) has been developed at the University of Munich, which locates and reports both cloud discharges and cloud-to-ground strokes with high accuracy. The network started operation in May 2006; since then lightning data for Europe are being delivered to many scientific groups, and to the German Weather Service (DWD) on an operational basis (powered by nowcast ...
Atmospheric discharge is one of the most interesting and powerful natural phenomenon hiding from men its undiscovered features and secrets for centuries. Lightning discharges have been studied in many theoretical and experimental ways. However, application of Fourier transform has been introduced in this research only in recent few decades. It proved very useful in solving many lightning resear...
The immediate consequences of terrorism are evident in the graphic news images of mayhem that quickly follow such events. But terrorism is like a stone tossed into a still pond. It triggers waves of consequence that ripple out over multiple timescales from the micro-level of the individual to the macro-level of international relations. The socio-political dynamics that terrorism triggers are un...
This manuscript describes the suite of instrumentation used and provides examples of some of the lightning and atmospheric electricity measurements and results obtained during the PEACH project of HyMeX SOP1. The results presented in this manuscript represent an important contribution to improving our understanding of storm and lightning activity in the Northwestern Mediterranean Sea and surrou...
[1] The 21 July 1998 thunderstorm observed during the European Lightning Nitrogen Oxides Project (EULINOX) project was simulated using the three-dimensional Goddard Cumulus Ensemble (GCE) model. The simulation successfully reproduced a number of observed storm features including the splitting of the original cell into a southern cell which developed supercell characteristics and a northern cell...
Observations of nearby lightning have been made in Brisbane, Australia (27.3oS, 153.0oE) from 1995 to 2010 using CGR3 and CGR4 lightning sensors and a 500 Hz CIGRE lightning flash counter, with the objective of measuring long-term lightning flash densities and their diurnal and annual variations. The observations with the CGR4 sensor covered a circular area around the sensor of about 400 km2. T...
Two cases of fatal lightning injury are described. Fixed dilated pupils should not be taken as an indicator of death after a lightning strike. Persons who fail to breath spontaneously within one minute of lightning shock should receive external cardiac massage and mouth-to-mouth resuscitation. Paralysis may persist as result of cerebral oedema or prolonged hypoxia-it is therefore suggested that...
This research focuses on an investigation of the attractive width of high voltage transmission lines to lightning strokes. In order to design the optimal lightning protection, the estimated number of lightning flashes to the line, which is based on its attractive width, needs to be determined. The investigation was performed using experiments with tested models at the Mississippi State Universi...
