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 ...
aLightning strikes represent a flow of current from negative to positive, in most cases, and many move from the bottom to the top of a cloud, from cloud to cloud, or mostfeared, from cloud to ground 雷击代表潮流流程从消极到正面,在许多情况下和许多移动从底部在一朵云彩的上面,从云彩到云彩或...

The objective of this research is to find a quantifiable relationship between CG lightning and precipitation in the lower Mississippi River Valley, which lies within a region that receives more warm-season rainfall and CG lightning than any other location of the US. This study is unique in that...
[1] The relationship of cloud-to-ground (CG) lightning strikes to the stages of updraft/downdraft evolution is investigated in a multicell thunderstorm that occurred on 11 July 1989 during the North Dakota Thunderstorm Project. With only single-Doppler radar data available for this storm, reflecti...
Do you know what makes lightning(闪电)? Why does lightning strike(击打)? Lightning strikes happen when ice and water in clouds rub(摩擦) together, and cause atmospheric(大气层的) changes. When this happens, it creates a static charge(静电). Lightning can strike inside the...
An improved stochastic method for computer simulation of lightning leaders is developed based on the results from optical observation data. The development and attachment process of downward negative cloud-to-ground lightning in the near-ground area is simulated. The distribution of lightning strike poin...
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...
The study confirmed the results of previous studies, finding a probabilistic relationship between thunderstorm intensity, as suggested by the height of the 40dBZ echo in relation to the estimated environment -10°C isotherm height, and the initiation and frequency of CG lightning strikes. Furthermore...
cloud-to-cloud lightning channel; perfect conducting soil; induced potentials in aircraft 1. Introduction Atmospheric discharges in which a vast amount of electric charge is exchanged between clouds and the ground or even between two clouds give rise to the formation of channels through which a ...
