Lightning Flowers
Lightning Flowers traces the psychological collapse of Waylan Dranger, an East Texas construction worker / folk artist. Waylan suffers from hallucinatory encounters with Reeve, his missing brother. Reeve often blames Waylan for his disappearance and implied death. Waylan also worries that Sam, his …

Lightning-bug, At Noon
This manuscript of poetry explores, or seeks to explore, the role non-human nature plays in human imagination and thought. The poems attempt to overlay a physical landscape onto a landscape of a subjective imagination, while trying to explore the phenomenon of metaphor – an act that is …

Simulating artificial lightning and composite damage
Lightning occurs during extreme weather conditions and can interact with aircraft during flight. Since aircraft are increasingly made of electrically resistive composites, rather than conductive metals, it is important to analyse the damage caused by a strike. Literature has shown lightning can be …

Influence of lightning on electron density variation in the ionosphere using WWLLN lightning data and GPS data
… (TID) in the ionosphere and tropospheric lightning in the mid-latitude region over South Africa. Lightning induced changes in total electron content (TEC) are strongest between September and March, with the more-pronounced effects occurring 12:00 - 22:00 UT, but from April through August …

Lightning/percipitation relationships on a global basis
Rainfall and lightning are measured and compared on a global basis using data gathered from the Tropical Rainfall Measuring Mission (TRMM) satellite, launched in November 1997. The satellite provides simultaneous lightning-precipitation measurements that allow for comprehensive relationships to be …

Assessing Lightning and Wild Fire Hazard by Land Properties and Cloud to Ground Lightning Data with Association Rule Mining over Alberta, Canada
Characteristics of Cloud to Ground (CG) lightning over Alberta, Canada were investigated by using 2010-2016 lightning data with data mining methods. The hotspot analysis was implemented to find the regions with high frequency CG lightning strikes clustered together. Generally, hotspot regions are …

Air breakdown under lightning impulse with plane-plane electrode
… setup to get the standard impulse voltage. This lightning impulse voltage is ensured to follow the standard of BS EN 60060-1:2010. The procedure of this experiment follows the TERCO catalogue documentation. In this project, the standard plane to plane gap is used to measure the peak value of DC …

Numerical Modeling Of Lightning Initiation And Stepped Leader Propagation
… at the beginning of cloud-to-ground (CG) lightning flashes and stepped leaders that folloIBPs were modeled using multi-sensor electric field change (E-change) measurements. This study uses data collected with a network of ten E-change sensors located at Kennedy Space Center. Locations …

Lightning Electromagnetic Pulse Functions and Protecting the Artemis Spacecraft
Lightning produces some of the most powerful electric currents found on Earth, which are usually measured near the bottom or base of the lightning channel. However, these lightning “channel-base currents” also produce Electromagnetic Pulses (EMPs) which are powerful enough to be measured from the …

Lightning effects on underground distribution cable using alternative transient program
… cables are not directly exposed to hazard, lightning can induce a potential on the insulation of the underground cable. About 80% of the lightning strikes in Malaysia produce voltage in excess of 20 kV. This study was done to determine the possibility of having insulation breakdown of the …
