Computation of electromagnetic fields from lightning discharge

open access: yes, 2014
Electromagnetic fields from lightning can couple to electrical systems and produce transient overvoltages, which can cause power and telecommunication outages and destruction of electronics.

3D Computation of Lightning Leader Stepped Propagation Inside a Realistic Cloud

open access: yesComptes Rendus. Physique
The simulation of lightning propagation is a complex problem studied for years. Here we propose to use the information from the electric potential created from a real cloud structure to study the propagation.

Lightning interaction with the ionosphere

open access: yes
Lightning discharges, including cloud-to-ground (CG) and intracloud (IC) lightning, are known to emit electromagnetic pulses (EMPs) in a wide frequency band ranging from few Hz up to hundreds MHz [1]. During the breakdown and ionization processes (mostly

Cloud-to-Ground Lightning in Cities: Seasonal Variability and Influential Factors

open access: yesEarth Systems and Environment
AbstractUrban-induced land use changes have a significant impact on local weather patterns, leading to increased hydro-meteorological hazards in cities. Despite substantial threats posed to humans, understanding atmospheric hazards related to urbanisation, such as thunderstorms, lightning, and convective precipitation, remains unclear.

Attachment of lightning flashes to grounded structures

open access: yes, 2012
A grounded structure can interact with a lightning flash in two different ways. It can interact with either a downward or an upward lightning flash. The initiation of a downward lightning flash takes place in the cloud, whereas in the case of upward ...

Tennessee Valley Total and Cloud-to-Ground Lightning Climatology Comparison

open access: yes, 2008
The North Alabama Lightning Mapping Array (NALMA) has been in operation since 2001 and consists often VHF receivers deployed across northern Alabama. The NALMA locates sources of impulsive VHF radio signals from total lightning by accurately measuring ...

Imaging of 3 bright terrestrial gamma-ray flashes by the atmosphere-space interactions monitor and their parent thunderstorms

open access: yesScientific Reports
The Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station (ISS) includes an instrument designed to geolocate Terrestrial Gamma-ray Flashes (TGF) produced by thunderstorms.

Wildfire-emitted aerosols modulate lightning occurrence and ignition potential in the boreal forest of Northeast China

open access: yesEnvironmental Research Letters
Wildfire-released greenhouse gases and aerosols accelerate global warming and exacerbate air pollution, substantially altering atmospheric composition and cloud microphysical properties.
