Automated analysis and statistics of lightning leader speed, local flash rates and electric charge structure in thunderstorms
Van der Velde, Oscar Arnoud; Montanya, Joan; López Trujillo, Jesús Alberto (2018)
Conference lecture
Open AccessWe introduce new methods for the analysis of complex three-dimensional lightning data produced by Lightning Mapping Arrays and illustrate them by cases of a mid-latitude severe weather producing thunderstorm and a tropical ... -
Evolution of gigantic jets at high temporal and spatial resolution
Van der Velde, Oscar Arnoud; Montanya, Joan; López Trujillo, Jesús Alberto (2018)
Conference lecture
Open AccessGigantic Jets (GJ) are lightning discharges between the cloud and the lower ionosphere, which manifest as leaders at low altitude and transition to streamers as they rise in altitude. The evolution has never been imaged ... -
Gigantic jet discharges evolve stepwise through the middle atmosphere
Van der Velde, Oscar Arnoud; Montanya, Joan; López Trujillo, Jesús Alberto; Cummer, Steven A. (2019-09-25)
Article
Open AccessIn 2002 it was discovered that a lightning discharge can rise out of the top of tropical thunderstorms and branch out spectacularly to the base of the ionosphere at 90¿km altitude. Several dozens of such gigantic jets have ... -
Meteorological aspects of winter upward lightning from an instrumented tower in the Pyrenees
Pineda, Nicolau; Montanya, Joan; Romero Durán, David; Bech, Joan; González Lopez, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessA case study of winter upward lightning is analysed. In particular, the study focuses on the meteorological aspects that favoured the triggering of upward lightning by an instrumented tower in the eastern Pyrenees. Starting ... -
On the classification of self-triggered versus other-triggered lightning flashes
Sunjerga, A.; Mostajabi, A.; Pineda Rüegg, Nicolau; Romero Durán, David; Van der Velde, Oscar Arnoud; Montanya, Joan; Azadifar, M.; Rubinstein, M.; Diendorfer, Gergard (Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessWe present in this paper lightning current measurements and LMA (Lightning Mapping Array) data associated with upward flashes observed at the Sàntis Tower during Summer 2017. The LMA network consists of six stations located ...
