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)
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 ...

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 ...

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 ...

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 ...

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 ...
