A system for dissipating a lightning current produced by a thunderstorm discharge on an avionic equipment installed on the external skin of an aircraft, the external skin being made of a composite material cove
2.Lightning is generated when electrical charges separate in rain clouds, though processes are still not fully understood. Typically, positive charges build at the cloud top, while the bottom becomes negatively charged. In most instances of cloud-to-ground lightning, the negatively charged lower po...
Thunderstorm modelsThunderstorm parametersSummary The stationary electric field inside a thunderstorm, which is generated by the movement of charged precipitation particles, causes the lightning discharges. The distribution of the stationary field in the cloud is reflected in the electric field of the ...
Thomas1, Mark A. Stanley1 & Yang Zhang3 A long-standing but fundamental question in lightning studies concerns how lightning is initiated inside storms, given the absence of physical conductors. The issue has revolved around the question of whether the discharges are initiated solely by ...
[MV/m]) must be generated in a volume that is relatively small but is above a certain critical size; at the same time, there must be an electric field in a substantial portion of the cloud whose intensity is sufficienty to sustain the discharge after its initiation (of the order of ...
Also shown is the path of the laser recorded with its second harmonic at 515 nm. Full size image Between 21 July and 30 September 2021, the laser was operated during a total of 6.3 h of thunderstorm activity occurring within 3 km of the tower. The tower was hit by at least 16...
A place for fun, learning, and exploration in the world of electricity and its technologies Lightningis a powerful natural electrostatic discharge produced during a thunderstorm. Lightning's abrupt electric discharge is accompanied by the emission of visible light and other forms of electromagnetic radia...
When an extensive shower passes through a thundercloud, its radio emission contains information about the cloud's electric field, enabling determination of both the field and thunderstorm charge distribution. This technique is applied at the LOFAR radio telescope, as detailed in Refs (Schellart et ...
The entire dataset acquired below 5.5 Jovian radii during the nominal part of the Juno mission by the LFR-hi receiver (326,466 snapshots) was visually inspected for lightning-generated Jupiter dispersed pulses (JDPs) propagating in the free-space ordinary mode through the low-density regions15with...
The known effects of thermodynamics and aerosols can well explain the thunderstorm activity over land, but fail over oceans. Here, tracking the full lifecycle of tropical deep convective cloud clusters shows that adding fine aerosols significantly increa
