The Timing of Cloud-to-Ground Lightning Relative to Total Lightning Activity

Monthly Weather Review, 2011
Abstract The first flash produced by a storm usually does not strike ground, but little has been published concerning the time after the first flash before a cloud-to-ground flash occurs, particularly for a variety of climatological regions. To begin addressing this issue, this study analyzed data from very-high-frequency (VHF) lightning

Sub Microsecond Analysis of Negative Cloud-To-Ground Lightning Flashes [PDF]

Indonesian Journal of Electrical Engineering and Computer Science, 2018
This paper expounds a development software for the identification of lightning discharge in cloud-to-ground flashes. The study was to reduce a misleading detection of the electric field radiation of a lightning discharge profile by considering the important parameters of sub microseconds structure of lightning return stroke.

Simulation of Cloud-to-Ground Lightning Strikes to Wind Turbines Considering Polarity Effect Based on an Improved Stochastic Lightning Model

Atmosphere, 2023
The accurate determination of the annual lightning flash number to a wind turbine is essential for designing proper lightning protection measures. However, the method to assess the lightning risk of wind turbines recommended by the IEC is not associated ...

Cloud-to-ground lightning and Mesoscale Convective Systems [PDF]

Atmospheric Research, 2011
AbstractThis work analyzes some physical and microphysical properties of Mesoscale Convective Systems (MCSs) and cloud-to-ground lightning. Satellite data from the GOES-10 infrared and NOAA-18 and TRMM microwave channels and lightning information from the Brazilian lightning detection network (BrasilDAT) were utilized for the period from 2007 to 2009 ...

Channel branching and zigzagging in negative cloud-to-ground lightning. [PDF]

Sci Rep, 2017
AbstractA fundamental question in lightning flash concerns why the discharge channel propagates in a zig-zag manner and produces extensive branches. Here we report the optical observation of two negative cloud-to-ground lightning discharges with very high temporal resolution of 180,000 frames per second, which shows in detail the dependence of channel ...

A Cloud-to-Ground Lightning Climatology for Romania [PDF]

Monthly Weather Review, 2010
Abstract The first study of the characteristics of cloud-to-ground (CG) lightning in Romania, based on the data recorded by the Romanian National Lightning Detection Network (RNLDN), is presented. The data, more than 1.75 million CG flashes, covers the entirety of Romania and were recorded between January 2003 and December 2005 and ...

Multi-stroke positive cloud-to-ground lightning sharing the same channel observed with a VHF broadband interferometer [PDF]

, 2022
In the same lightning flash, whose usual duration is less than a second, there can be multiple negative cloud-to-ground strokes with different terminations or following a preexisting channel to the ground.

Numerical Model of Cloud-to-Ground Lightning for PyroCb Thunderstorms

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
This paper demonstrates a 2-D numerical model to represent two conceptual pyrocumulonimbus (pyroCb) thundercloud structures: i) tilted dipole and ii) tripole structure with enhanced lower positive charge layer, which are hypothesized to explain the occurrence of lightning flashes in pyroCb storms created from severe wildfire events. The presented model
