The Impact of High-Resolution SRTM Topography and Corine Land Cover on Lightning Calculations in WRF

Atmosphere, 2022
The goal of this study is to investigate the impact of high-resolution SRTM and Corine Land Cover on the number of cloud–ground lightning flashes and their spatial distribution simulated by a numerical weather-prediction model.

A Baseline for the Predictability of U.S. Cloud‐to‐Ground Lightning [PDF]

Geophysical Research Letters, 2018
AbstractThe product of convective available potential energy and precipitation rate is used as a proxy for U.S. cloud‐to‐ground (CG) lightning. The proxy is computed from numerical weather prediction model outputs and thus provides a simple method for producing CG lightning threat forecasts.

Potential Relationship Between Aerosols and Positive Cloud-to-Ground Lightning During the Warm Season in Sichuan, Southwest China

Frontiers in Environmental Science, 2022
This study discussed the influence of aerosols on the relative frequency of positive cloud-to-ground (CG) lightning and its dependence on thermodynamic and cloud-related factors in Sichuan during the warm season from 2005 to 2017.

Diurnal differences in the effect of aerosols on cloud-to-ground lightning in the Sichuan Basin [PDF]

Atmospheric Chemistry and Physics, 2023
The effect of aerosols on lightning has been examined in many studies, but its mechanisms are complex and far from understood. This study investigated the influence of aerosols on cloud-to-ground (CG) lightning during both afternoon (12:00–18:00 Beijing ...

Characterization of negative cloud-to-ground lightning in Florida [PDF]

Journal of Atmospheric and Solar-Terrestrial Physics, 2015
Abstract We examined characteristics of negative cloud-to-ground lightning flashes using their electric field waveforms acquired at the Lightning Observatory in Gainesville (LOG), Florida in the summers of 2013 and 2014. Flash multiplicity, interstroke interval, flash duration, and first to subsequent stroke field peak ratio are determined for 478 ...

Formation of Saturn's ring spokes by lightning-induced electron beams [PDF]

, 2006
Spokes are near-linear markings sometimes visible on Saturn's rings. They are widely accepted as being electrostatically-levitated sheets of similar to 0.6 micron-radius charged grains.
