Intense oceanic lightning
The electrodynamic properties of intense oceanic lightning discharges are compared to intense continental lightning discharges. Particularly intense negative lightning discharges with absolute charge moments > 2 kC·km occur more often over the oceans than over the continents during April 1998. Intense continental lightning discharges, with negative and positive polarity, and intense positive oc...
متن کاملIon runaway in lightning discharges.
Runaway ions can be produced in plasmas with large electric fields, where the accelerating electric force is augmented by the low mean ionic charge due to the imbalance between the number of electrons and ions. Here we derive an expression for the high-energy tail of the ion distribution function in lightning discharges and investigate the energy range that the ions can reach. We also estimate ...
متن کاملPhotogrammetric 3d Reconstruction of Lightning Discharges
A computer vision setup is presented for the automated detection and multi-view 3D reconstruction of lightning discharges. The system is designed to operate autonomously in a continuous mode and provide accurate position information of the lightning discharge path and impact point relative to its surrounding area. Extensive tests in a medium scale laboratory environment show that a relative mea...
متن کاملOn phenomenology of compact intracloud lightning discharges
[1] We examined wideband electric fields, electric and magnetic field derivatives, and narrowband VHF (36 MHz) radiation bursts produced by 157 compact intracloud discharges (CIDs). These poorly understood lightning events appear to be the strongest natural producers of HF‐VHF radiation. All the events transported negative charge upward (or lowered positive charge), 150 were located by the U.S....
متن کاملPositive and Bipolar Lightning Discharges: a Review
Characteristics of lightning discharges that transport either positive charge or both negative and positive charges to ground are reviewed. Different types of positive and bipolar discharges are discussed.
