Lightning Rings and Gravity Waves: Insights Into the Giant Eruption Plume From Tonga's Hunga Volcano on 15 January 2022

Geophysical Research Letters, 2023
On 15 January 2022, Hunga Volcano in Tonga produced the most violent eruption in the modern satellite era, sending a water‐rich plume at least 58 km high.

Spatiotemporal Correlation between Artificially Triggered and Adjacent Natural Lightning Flashes

Remote Sensing, 2022
A triggered lightning flash (TLF) provides a unique perspective on the relationship between spatiotemporal proximity flashes, owing to its determined location and time, convenient direction measurement, and explicit association with the charge region. In

On the Classification of Self-Triggered versus OtherTriggered Lightning Flashes [PDF]

2018 34th International Conference on Lightning Protection (ICLP), 2018
We present in this paper lightning current measurements and LMA (Lightning Mapping Array) data associated with upward flashes observed at the Sàntis Tower during Summer 2017. The LMA network consists of six stations located in the vicinity of the tower at distances ranging from 100 m to 11 km from it.

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...

A Multiyear CONUS‐Wide Analysis of Lightning Strikes to Wind Turbines

Wind Energy
Lightning strikes to wind turbines (WTs) pose significant hazards and operational costs to the renewable wind industry. These strikes fall into two categories: downward cloud‐to‐ground (CG) strokes and upward discharges, which can be self‐initiated or ...

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

The Journal of Wildlife Management, EarlyView.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.
