网络云间闪电;云际闪电;云间放电 网络释义
Both lines were initially associated with cloud-to-ground (CG) lightning, as detected by the National Lightning Detection Network, and both events met the criteria to be classified as derechos, producing swaths of widespread damaging wind. After moving into areas of marginal, if any, instability ...
Six years of Bureau of Land Management (BLM) lightning data were used to investigate the distribution of lightning across New Mexico during the summer. Since lightning indicates the presence of thunderstorms, the BLM database also provided information on the spatial and temporal variations of deep,...
Cloud-to-ground lightning bolts(闪电) are a common phenomenon—about 100 strike the Earth’s surface every single second—yet their power is extraordinary. Each bolt can contain up to one billion volts (伏特)of electricity. This enormous electrical discharge is caused by an imbalance between ...

Presents information on the characteristics of the cloud-to-ground lightning flashes from 1989 to 1998 in the United States. Information on the mean annual density of lightning flashes; Analysis of positive flashes; Presentation of the geographical distribution of negative and positive multiplicity.年份...
About 1.1 million cloud-to-ground lightning flashes were recorded by a lightning positioning and tracking system in southeastern Brazil in 1993. The 1-year continuous lightning data set is the first obtained in Brazil. It has been analyzed for geographical distribution of total flash density, percen...

The current status of the Japanese coastal region shows that winter lightning has seriously damaged wind turbines owing to its larger electrical charge than summer lightning. In Japan, 64% of serious wind turbine damage occurred in winter. Typically, lightning flash density is used to evaluate light...
Although negative ground flashes usually dominate cloud-to-ground lightning activity, positive ground flashes can dominate in some severe storms for periods ranging from 30 min to several hours. Unlike most other types of storms in which positive ground flashes occur, severe storms can have positive...
