Storm <i>Ciarán</i>'s effect on the boiling point of water in the southeast of the United Kingdom Open
The spatial atmospheric pressure field due to Storm Ciarán is investigated in the south‐east of the UK at high temporal and spatial resolution using data from roadside sites. During Ciarán’s passage, a reduction in the boiling point of wat…

Long-Term Observations of Schumann Resonances at Portishead (UK) Open
Constructive interference of lightning-generated signals in the extremely low frequency (ELF) below 100 Hz is the source of a global electromagnetic phenomenon in the Earth’s atmosphere known as Schumann Resonances (SR). SR are excited at …

Long-term observation of electrical discharges during persistent Vulcanian activity Open
Very low frequency and wide-band lightning detection networks can detect major volcanic plumes via their intense electrical and lightning activity. However, the high number of non-detected explosive episodes confirmed by direct observation…

Analysis of sprite events during small-scale winter thunderstorms in northern Europe Open
<p>Lightning occurrence throughout Europe is at a minimum in winter and mostly confined around the coastlines of the Mediterranean. Limited extent winter thunderstorms at higher latitudes are nevertheless found to produce intense CG …

Extremely low frequency detection of electrical discharges at Minamidake crater (Sakurajima volcano, Japan) Open
<p>Volcanoes are increasingly better monitored around the world. Nonetheless, the detection and monitoring of volcanic ash plumes remains difficult, especially in remote areas. Intense electrical activity and lightning in volcanic pl…

Lower Ionospheric Conductivity Modification Above a Thunderstorm Updraught Open
Lightning has previously been observed to disturb the lower ionosphere. These lightning‐induced ionospheric perturbations were observed as disturbances on subionospheric low‐frequency radio wave propagation with fast rise times 10 s. Most …

First In Situ Observations of Gaseous Volcanic Plume Electrification Open
Volcanic plumes become electrically charged, often producing spectacular displays of lightning. Previous research has focused on understanding volcanic lightning, primarily the large electric fields produced by charging of ash particles. H…

Saharan dust plume charging observed over the UK Open
A plume of Saharan dust and Iberian smoke was carried across the southern UK on 16th October 2017, entrained into an Atlantic cyclone which had originated as Hurricane Ophelia. The dust plume aloft was widely noticed as it was sufficiently…

Advances in lightning detection Open
A well-attended meeting on the latest developments in lightning detection was hosted by the Department of Meteorology, University of Reading, on 9 March 2016. The meeting was jointly organised by the Royal Meteorological Society's Meteorol…

Lightning as a space‐weather hazard: UK thunderstorm activity modulated by the passage of the heliospheric current sheet Open
Lightning flash rates, R L , are modulated by corotating interaction regions (CIRs) and the polarity of the heliospheric magnetic field (HMF) in near‐Earth space. As the HMF polarity reverses at the heliospheric current sheet (HCS), typica…
