  • 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 Access
    We 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 Access
    Gigantic 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 ...
  • 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 Access
    A 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 Access
    We 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 ...
  • Thunderstorm characteristics favouring downward and upward lightning to wind turbines 

    Pineda, Nicolau; Montanya, Joan; Salvador Yuste, Albert; Van der Velde, Oscar Arnoud; López Trujillo, Jesús Alberto (2018-12-01)
    Article
    Restricted access - publisher's policy
    Meteorological conditions and thunderstorm characteristics related to lightning threats to wind turbines are discussed in this paper. Due to the rotating blades, wind turbines may be regarded peculiar tall objects, more ...
