Lightning Current Distribution of the First and Subsequent Strokes Based on the Lightning Location System: Survey in Yunnan Power Grid

Atmosphere
Lightning is an electrical discharge phenomenon in the atmosphere caused by charge separation in clouds, which is divided into cloud-to-ground (CG) and cloud-to-cloud (CC) lightning.

Bipolar cloud‐to‐ground lightning flash observations [PDF]

Journal of Geophysical Research: Atmospheres, 2013
AbstractBipolar lightning is usually defined as a lightning flash where the current waveform exhibits a polarity reversal. There are very few reported cases of cloud‐to‐ground (CG) bipolar flashes using only one channel in the literature. Reports on this type of bipolar flashes are not common due to the fact that in order to confirm that currents of ...

Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)

Characterizing Pulse Attenuation of Intra-Cloud and Cloud-to-Ground Lightning with E-Field Signal Measured at Multiple Stations

Remote Sensing, 2022
In this paper, we analyze the waveform data of nearly 200,000 intra-cloud (IC) and cloud-to-ground (CG) lightning discharges detected by the Jianghuai Area Sferic Array on 26–29 August 2019 to investigate the propagation features of lightning ...

Impact of fragmented urbanization on observed precipitation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the impact of fragmented urban landscapes on downwind precipitation by applying an innovative observation‐centered approach to an extensive rain gauge network in Belgium. The approach classifies the observations based on the upwind urban land cover fraction, and compares precipitation indices between rural‐ and urban‐labeled ...

Fatal lightning strikes in Ireland from newspaper records 1900–2024

Weather, EarlyView.
This study presents a chronology of fatal lightning strikes in Ireland (1900–2024) derived from digitised newspaper archives. Analysis provides insights into the seasonality, location, victim activity and synoptic conditions (from Lamb weather types) of 94 fatal events causing 113 deaths.

Estimates of lightning ground flash density in Australia and its relationship to thunder-days [PDF]

, 2004
A method of deriving lightning ground flash density from CIGRE lightning flash counter registrations based on the detection efficiency of the instrument, independent of the latitudinal variation of cloud flash-to-ground flash ratio is presented.

A Survey and Perspectives on Mathematical Models for Quantitative Precipitation Estimation Using Lightning

Advances in Meteorology, 2017
Lightning is one of the most spectacular phenomena in nature. It is produced when there is a breakdown in the resistance in the electric field between the ground and an electrically charged cloud.
