Wind Turbine Blade Crack Detection and Assessment in Images Using Machine Learning

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT As the wind energy industry matures, inspection of wind turbine blades (WTBs) is shifting from a manual process involving rope access and grading of damage, towards unmanned aerial vehicle (UAV) photography and artificial intelligence‐aided processing of data.

Stroke multiplicity and horizontal scale of negative charge regions in thunderclouds

Geophysical Research Letters, 2016
An X‐band polarimetric radar and multiple lightning detection systems are used to document the initial cloud‐to‐ground lightning flash in a large number (46 cases) of incipient thunderstorms, as part of the CHUVA‐Vale field campaign during the 2011/2012 ...

How weather got its words: a history of meteorological English – Part 1: Old English to the Age of Discovery

Weather, Volume 81, Issue 9, Page 306-311, September 2026.
The English language is a gargantuan, gluttonous beast. It has become extraordinary among its peers in its powers of assimilation – such that we rarely consider the diverse origins of the words we use. In this two‐part paper, we will explore these origins, including the Pontic‐Caspian steppe, the British Empire, latinophone scientists and a TV show. We

Horizontal channel lengths of cloud to ground lightning flashes

, 2018
This work utilized data from Lightning Mapping Array (LMA) networks and the National Lightning Detection Network (NLDN) to assess the relationship between lightning channel lengths and lightning current in cloud-to-ground (CG) lightning flashes. The LMA

Probabilistic Forecasting of Lightning Strikes over the Continental USA and Alaska: Model Development and Verification

Fire
Lightning is responsible for the most area annually burned by wildfires in the extratropical region of the Northern Hemisphere. Hence, predicting the occurrence of wildfires requires reliable forecasting of the chance of cloud-to-ground lightning strikes

Burn Severity as a Driver of Multi‐Year Increases in Gross Primary Production and Solar‐Induced Fluorescence Following a Wildfire in Arctic Tundra

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract While climate‐driven increases in wildfires are altering the composition and function of Arctic ecosystems, the impact of burn severity on longer‐term changes in community composition and ecosystem fluxes remains less understood, creating uncertainty in estimates of the biome's carbon storage capacity.
