    In 1999, the first sprites were observed above European thunderstorms using sensitive cameras. Since then, Eurosprite campaigns have been conducted to observe sprites and other transient luminous events (TLEs), expanding ...
  • Analysis of the lightning production of convective cells 

    Figueras i Ventura, Jordi; Pineda Rüegg, Nicolau; Besic, Nikola; Grazioli, Jacopo; Hering, Alessandro; Van der Velde, Oscar Arnoud; Romero Durán, David; Sunjerga, A.; Mostajabi, A.; Azadifar, M.; Rubinstein, M.; Montanya, Joan; Germann, Urs; Rachidi-Haeri, Farhad (2019-10-22)
    Article
    Open Access
    This paper presents an analysis of the lightning production of convective cells. The cells were detected by the MeteoSwiss Thunderstorms Radar Tracking (TRT) algorithm in the course of a lightning measurement campaign that ...
  • Wakefield acceleration in planetary atmospheres: a possible source of MeV electrons : the collisionless case 

    Arrayas Chazeta, Manuel; Cubero Gómez, David; Montañá Puig, Juan; Seviour, Rebecca; Trueba Santander, Jose Luis (2018-07-01)
    Article
    Open Access
    Intense electromagnetic pulses interacting with a plasma can create a wake of plasma oscillations. Electrons trapped in such oscillations can be accelerated under certain conditions to very high energies. We study the ...
  • Meteorological aspects of self-initiated upward lightning at the Säntis Tower (Switzerland) 

    Pineda, Nicolau; Figueras i Ventura, Jordi; Romero Durán, David; Mostajabi, A.; Azadifar, M.; Sunjerga, A.; Rachidi-Haeri, Farhad; Rubinstein, M.; Montanya, Joan; Van der Velde, Oscar Arnoud; Altube Vázquez, Patricia; Besic, Nikola; Grazioli, Jacopo; Germann, Urs; Williams, Earle R. (2019-12-26)
    Article
    Open Access
    Interest in exploring the meteorological conditions favoring upward lightning from tall man-made structures has grown in recent years, largely due to the worldwide expansion of wind energy. To this end, instrumented towers ...

    We present in this paper lightning current measurements, LMA (Lightning Mapping Array) data and fast antenna electric fields associated with upward flashes observed at the Säntis Tower during summer of 2017. The LMA network ...
  • 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 Access
    In 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 ...
