Characteristics of lightning flashes generating sprites above storms (i-DUST)
(EDP Sciences, 2016)
Conference report
Open AccessSprites are Transient Luminous Events (TLEs) that can extend vertically from 40 to 90 km and horizontally over several tens of km to form clusters of individual or multiple column or/and carrot-shaped luminous elements. ... -

Charge structure of two tropical thunderstorms in Colombia
(2019-04-23)
Article
Open AccessCharge structure derived from lightning leader development of tropical thunderstorms comprising equatorial latitudes of < ±10° has not been investigated yet. In this work, using a Lightning Mapping Array (LMA) installed ... -
Coastal wave storms: Observations and simulations in the NW Mediterranean
(Universitat Politècnica de Catalunya, 2009-06-03)
Master thesis
Open AccessThe importance of improving wind-wave predictions for the NW Mediterranean coastal region makes it necessary to perform a study in-depth of wave generation and propagation mechanisms under sharp spatial and temporal ... -
Comparison of global RHESSI and AGILE TGFs distributions and analysis of all AGILE satellite passes over South America. 2009-2012 period
(2014)
Conference report
Open AccessRHESSI and AGILE TGFs distributions in the period 2009-2012 are compared. Analysis of differences in geographical, hourly, monthly distributions of the three main TGF production regions in Earth due to differences in ... -
Dancing sprites: detailed analysis of two case studies
(2017-03-27)
Article
Open AccessOn 29–30 October 2013, a low-light video camera installed at Pic du Midi (2877¿m), recorded transient luminous events above a very active storm over the Mediterranean Sea. The minimum cloud top temperature reached -73°C, ... -
Effects of the topography on the thundercloud electrostatic field measurements
(2014)
Conference report
Open AccessThis paper presents thunderstorm electrostatic field measurements carried out by electric field mills located at mountainous regions in Spain and Colombia. The profile of electric field changes ¿E due to lightning vs ... -

Gravel deposit produced by a flash paleoflood in a succession of Quaternary terraces in the Plain of Vic (NE Iberian Peninsula)
(2016)
Conference lecture
Open AccessIn contrast with the abundance of studies of fluvial terraces, caused by river dynamics, there are very few descriptions of alluvial deposits produced by flash floods and mass movements. This ... -
High altitude leaders mapped by the Colombia lightning mapping array
(2016)
Conference report
Open AccessOn April 2015 a Lightning Mapping Array network (COL-LMA) was installed at the north of Colombia. This network provides 3D mapping of the development of lightning leaders. For the first time such network has been setup in ... -
Multivariate statistical modelling of future marine storms
(2017-04)
Article
Open AccessExtreme events, such as wave-storms, need to be characterized for coastal infrastructure design purposes. Such description should contain information on both the univariate behaviour and the joint-dependence of storm-variables. ... -
On the TGF/lightning ratio asymmetry
(2019-05-14)
Article
Open AccessAfrica is one of the most productive lightning regions on Earth, yet it has a lower TGF-to-lightning ratio especially compared with Central America. In this paper we have analyzed the global distribution of different ... -

(Universitat Politècnica de Catalunya, 2010-07-30)
Minor thesis
Open AccessDesde hace unos años ha habido un aumento de la cantidad de información referente a los daños, producidos, en número e intensidad por las tormentas ocurridas en la costa catalana. Lo que no se puede establecer con seguridad ... -
Sprites and elves as proxy of energetic lightning flashes in winter: what can we learn from mesospheric discharges for the protection of wind turbines?
(2011)
Conference report
Open AccessSprites and Elves are commonly observed in Europe, especially also in winter maritime storms. It is well known that sprites are related to large electric charge positive flashes and elves are related with high amplitude ... -
Statistics and variability of the altitude of elves
(2016-05-07)
Article
Open AccessFrom June 2008 to January 2016 nearly 800 elves have been recorded by a low-light camera in northeastern Spain. Elves occur in this region mainly over the lower-topped cold airmass maritime thunderstorms, peaking from ... -
Study of single-flash thunderstorms over wind farms in the Basque Country
