Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Electrification in winter storms and the analysis of thunderstorm overflight [PDF]

open access: yes
The emergence of 24 hr operational lightning detection networks has led to the finding that positive lightning strokes, although still much fewer in number than the normal negative strokes, are present in summer and winter storms.

Flashover performance of lightning protected buildings using scaled models and electric field analysis [PDF]

open access: yes, 2018
In early era, Benjamin Franklin discovered that the application of Lightning Rod (also known as the Franklin Rod) method is found to be effectived as a lightning protective device for buildings.

Anomalous electric field changes and high flash rate beneath a thunderstorm in northeast India [PDF]

open access: yes, 2010
In spite of many experimental and theoretical studies the relationships between storm dynamics, severe weather, and lightning activity have been least understood.

Organic Representation as a Critical Media Approach to Leadership Studies in Popular Culture

open access: yesNew Directions for Student Leadership, Volume 2025, Issue 185, Page 75-80, Spring 2025.
ABSTRACT This article applies the critical media concept of organic representation to leadership studies as an analytic of how various creators in popular culture today are not just writing inclusive storytelling but, more notably, modeling new modes of production and self‐presentation that are actively challenging hegemonic industry practices and ...

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

OLS data system/global survey of lightning [PDF]

open access: yes
A global lightning climatology is being assembled from the nighttime imagery of the DMSP Optical Linescan Sensor (OLS). Lightning saturates the visible channel of the OLS at nighttime and can be identified as a horizontal streak on the order of 50-100 km

Seasonal variation of transmission line outages in Peninsular Malaysia [PDF]

open access: yes, 2017
Researchers have observed the impact of climate changes on overhead line outages. It is known that overhead lines are very prone to lightning strikes due to their height and location which are normally in an open and exposed area.

Modulation of UK lightning by heliospheric magnetic field polarity [PDF]

open access: yes, 2014
Observational studies have reported solar magnetic modulation of terrestrial lightning on a range of time scales, from days to decades. The proposed mechanism is two-step: lightning rates vary with galactic cosmic ray (GCR) flux incident on Earth, either
