Simulation of the ball lightning phenomenon

Rendering images of outdoor scenes capturing the magnificence of the natural world is a challenging task for computer graphics. One natural phenomenon that has received no attention in the field of computer graphics and scarce attention in physics is ball lightning. A computer simulation would greatly improve animated sequences of thunderstorms where this rare feature most often occurs. A physi...

Lightning Discharge and Fundamentals of Lightning Protection

A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the topological shielding are presented. Bonding require...

Lightning Protection

Lightning causes deaths, injuries, damages, and significant costs and losses around the world. The global lightning flash rate is in the range of 40 to 100 lightning flashes per second, of which about 30 % are cloud-to-ground flashes. The development of theoretical and experimental researches is crucial for a better understanding of the physical phenomenon and for the characterization of lightn...

Lightning injuries.

Lightning is persistently one of the leading causes of death caused by environmental or natural disaster. To understand the pathophysiology and treatment of lightning injuries one must first discount the innumerable myths, superstitions, and misconceptions surrounding lightning. The fundamental difference between high voltage electrical injury and lightning is the duration of exposure to curren...
