A case of winter lightning initiation from a tall structure in the Basque Country
(2010)
Comunicació de congrés
Accés restringit per decisió de l'autorLightning research is usually focused on the most active months of the year, those corresponding to the summer season. These thunderstorms produce most of the lightning records during a year in the Basque Country, and ... -
A closer look at lightning reveals needle-like structures
(Macmillan Publishers, 2019-04-17)
Article
Accés obertStructural features have been identified on positively charged lightning channels that are not present on negatively charged ones. The discovery could explain why these two types of channel have different behaviours. -

(2010-11-09)
Article
Accés restringit per política de l'editorialOn the night from 1st to 2nd of November 2008, a multi-cell storm coming from the Mediterranean produced severe weather in the coastal area of Catalonia (NE Spain): groundlevel strong damaging wind gusts, a tornado – ... -
A numerical solver to assess the impact of wind, geometry, and altitude on artificial charge control of aircraft using corona discharge
(2022)
Text en actes de congrés
Accés restringit per política de l'editorialPrior work by members of the team has shown that active charge control might reduce the risk of aircraft-triggered lightning. Controlling the net charge of an aircraft can be achieved by using corona discharge. For a ... -
A simple method to estimate the return stroke current from close electric field measurements
(2004)
Comunicació de congrés
Accés restringit per decisió de l'autorDuring summers 2003 and 2004 a measurement campaign was carried out over Catalonia (N-E of Spain). In these campaigns, lightning electrostatic field as well electric and magnetic fields were measured. This paper describes ... -

Aircraft Charging and its Influence on Triggered Lightning
(2020-01-16)
Article
Accés obertThis paper reports on a laboratory experiment to study the effect of vehicle net charge on theinception of a positive leader from an aircraft exposed to high atmospheric electric fields. The experimentmodels the first stage ... -
Aliasing of the Schumann resonance background signal by sprite-associated Q-bursts
(2017-12)
Article
Accés obertThe Earth's naturally occurring Schumann resonances (SR) are composed of a quasi-continuous background component and a larger-amplitude, short-duration transient component, otherwise called ‘Q-burst’ (Ogawa et al., 1967). ... -
An improved analysis of mesoscale convective systems in the western Mediterranean using weather radar
(2019-10)
Article
Accés obertThis article studies the life cycle of the well-organised mesoscale convective systems (MCSs) that affect Catalonia and surrounding regions, using a weather radar composite with sophisticated corrections and lightning data ... -
Analysis of energetic radiation associated with thunderstorms in the Ebro delta region in Spain
(2016-08-25)
Article
Accés obertThe analysis of high-energy background radiation (0.1 – 2 MeV) enhancements during eight winter thunderstorms and ¿ve summer storms in the Ebro delta region in the northeast of Spain is presented. For the ¿rst time, ... -
