[Lightning-caused fire, its affecting factors and prediction: a review].
Lightning-caused fire is the most important natural fire source. Its induced forest fire brings enormous losses to human beings and ecological environment. Many countries have paid great attention to the prediction of lightning-caused fire. From the viewpoint of the main factors affecting the formation of lightning-caused fire, this paper emphatically analyzed the effects and action mechanisms ...
متن کاملBiotic and abiotic regulation of lightning fire initiation in the mixedwood boreal forest.
Lightning fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition on lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how these biotic and abiotic components contribute to ecosystem dynamics in the mixedwood boreal forest. We...
متن کاملModeling Forest Lightning Fire Occurrence in the Daxinganling Mountains of Northeastern China with MAXENT
Forest lightning fire is a recurrent and serious problem in the Daxinganling Mountains of northeastern China. Information on the spatial distribution of fire danger is needed to improve local fire prevention actions. The Maxent (Maximun Entropy Models), which is prevalent in modeling habitat distribution, was used to predict the possibility of lightning fire occurrence in a 1 × 1 km grid based ...
متن کاملCloud-to-Ground Lightning Downwind of the 2002 Hayman Forest Fire in Colorado
The Hayman forest fire occurred near Denver, burning ~138,000 acres during 8 June-2 July 2002. It produced aerosol that filled the troposphere over Colorado, allowing an investigation of the effects of increased aerosol concentration on cloud-to-ground (CG) lightning polarity. Specifically, we examine whether positive CG (+CG) flashes are favored in smoky environments. Aerosol optical depth (AO...
متن کاملLightning 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...
