Laser-guided lightning [PDF]

open access: yesNature Photonics, 2022
A terawatt laser filament is shown to be able to guide lightning over a distance of 50 m in field trials on the Säntis mountain in the Swiss Alps. Lightning discharges between charged clouds and the Earth’s surface are responsible for considerable ...

Variation of lightning-ignited wildfire patterns under climate change

open access: yesNature Communications, 2023
Lightning is the main precursor of natural wildfires and Long-Continuing-Current (LCC) lightning flashes are proposed to be the main igniters of lightning-ignited wildfires (LIW).

Extratropical forests increasingly at risk due to lightning fires

open access: yesNature Geoscience, 2023
Fires can be ignited by people or by natural causes, which are almost exclusively lightning strikes. Discriminating between lightning and anthropogenic fires is paramount when estimating impacts of changing socioeconomic and climatological conditions on ...

Lightning patterns in the Pantanal: Untangling natural and anthropogenic-induced wildfires.

open access: yesScience of the Total Environment, 2022
The identification of fire causes and characteristics is of fundamental importance to better understand fire regimes and drivers. Particularly for Brazil, there is a gap in the quantification of lightning-caused fires.

Future increases in lightning ignition efficiency and wildfire occurrence expected from drier fuels in boreal forest ecosystems of western North America

open access: yesEnvironmental Research Letters, 2022
Lightning-induced fire is the primary disturbance agent in boreal forests. Recent large fire years have been linked to anomalously high numbers of lightning-caused fire starts, yet the mechanisms regulating the probability of lightning ignition remain ...

Spatio-temporal variability of lightning climatology and its association with thunderstorm indices over India

open access: yesTheoretical and Applied Climatology, 2022
Lightning is an electrical discharge — a ‘spark’ or ‘flash’ as charged regions in the atmosphere instantly balance themselves through this discharge. It is a beautiful and deadly naturally occurring phenomenon.

The WGLC global gridded lightning climatology and timeseries

open access: yesEarth System Science Data, 2021
. Lightning is one of the most important atmospheric phenomena and has wide ranging influence on the Earth System, but few long-term observational datasets of lightning occurrence and distribution are currently freely available.

The bubble formation characteristics of oil‐paper insulation and its influence on insulation performance

open access: yesHigh Voltage, 2023
Engineering experience shows that for transformers with long service life and serious moisture exposure, the inter‐turn paper insulation inside the winding will precipitate bubbles under the condition of electric field and conductor heating, which will ...

Lightning occurrences and intensity over the Indian region: Long-term trends and future projections

open access: yesAtmospheric Chemistry and Physics, 2021
. Lightning activities constitute the major destructive component of thunderstorms over India. Hence, understanding the long-term variabilities of lightning occurrence and intensity and their inter-relation with various causative factors is required ...
