    Negative downward leaders that produced lightning strokes to wind turbines are identified by means of the Lightning Mapping Array data of the Ebro Valley Laboratory (NE Spain). Four cases are analyzed together with weather ...
  • Electromagnetic radiation of simulated mid-gap streamers 

    Montañá Puig, Juan; Fabró Tàpia, Ferran (Zakon Group, 2016)
    Text en actes de congrés
    Accés obert
    Electromagnetic field from simulated double-headed mid-gap streamers is computed. The effect of the applied electric field is studied by considering electric fields higher than the conventional breakdown threshold ...
