Localized resources enable noninvasive genetic monitoring of small populations of mountain ungulates

open access: yesWildlife Society Bulletin, EarlyView.
Using microsatellite analysis of fecal samples collected at mineral licks from 2019–2022, we assessed abundance, apparent survival and genetics of bighorn sheep in the Teton Range, Wyoming, USA. Annual abundance estimates ranged from 118−132 individuals split into 2 similar‐sized demes and apparent survival estimates ranged from 0.72–0.92.

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

open access: yesHigh Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Exceptional sequence of severe thunderstorms and related flash floods in May and June 2016 in Germany – Part 1: Meteorological background

open access: yes, 2016
. During a 15-day episode from 26 May to 9 June 2016, Germany was affected by an exceptionally large number of severe thunderstorms. Heavy rainfall, related flash floods and creek flooding, hail, and tornadoes caused substantial losses running into ...

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

open access: yesHigh Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Lightning Overvoltage Protection Technologies for High‐Speed Railway Traction Power Supply Systems: Current Status and Future Prospects

open access: yesHigh Voltage, EarlyView.
ABSTRACT The traction power supply system of high‐speed railways is exposed to complex lightning environments over the long term. Overvoltage generated by direct lightning or induced lightning can propagate along the overhead contact line, traction substations, onboard high‐voltage system and mobile grounding system, thereby threatening equipment ...

Propagation characteristics of thunderstorms in southern Germany

open access: yes, 1998
The propagation of thunderstorms in southern Germany was investigated. The thunderstorms were observed by a lightning position system during the summer months of the years 1992 to 1996.

Climate and weather analysis of Afghanistan thunderstorms [PDF]

open access: yes, 2011
Thunderstorms are a significant factor in the planning and execution of Defense (DoD) operations in Afghanistan, especially in the spring and summer. Skillful forecasting of Afghanistan thunderstorms has proven difficult, even at relatively short lead ...

A Novel Approach for the Detection of Developing Thunderstorm Cells

open access: yesRemote Sensing, 2019
This study presents a novel approach for the early detection of developing thunderstorms. To date, methods for the detection of developing thunderstorms have usually relied on accurate Atmospheric Motion Vectors (AMVs) for the estimation of the cooling ...

Natural History of Alternaria Sensitisation and Association With Asthma and Rhinitis From Childhood to Adulthood

open access: yesAllergy, EarlyView.
We aimed to characterise Alternaria sensitisation trajectories from childhood to adulthood; we compared SPT, whole‐extract sIgE and rAlt a 1, and assessed their longitudinal association with asthma and rhinitis in the Isle of Wight birth cohort. Alternaria sensitisation in the Isle of Wight Birth Cohort emerges mainly in late adolescence and, when ...

Thunderstorms and thunderstorm precipitations in southern Poland [PDF]

open access: yesEnvironmental & Socio-economic Studies, 2014
Abstract This paper addresses spatial and temporal variability in the occurrence of thunderstorms and related precipitation in southern Poland between 1951 and 2010. The analysis was based on thunderstorm observations and daily precipitation totals (broken down into the few ranges) from 15 meteorological stations.
