    • 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 ...
    • LMA observation of upward flashes at Säntis Tower: preliminary result 

      Mostajabi, A.; Pineda Rüegg, Nicolau; Romero Durán, David; Azadifar, M.; Van der Velde, Oscar Arnoud; Montañá Puig, Juan; Rubinstein, M.; Rachidi, F (2018)
      Conference report
      Open Access
      Lightning striking tall towers is mainly of the upward lightning type, which is characterized by the absence of a first return stroke and the presence of an initial continuous current (ICC) with or without superimposed ...
    • LMA observations of upward lightning flashes at the Säntis Tower initiated by nearby lightning activity 

      Sunjerga, A.; Rubinstein, M.; Pineda, Nicolau; Mostajabi, A.; Azadifar, M.; Romero Durán, David; Van der Velde, Oscar Arnoud; Montanya, Joan; Figueras i Ventura, Jordi; Besic, Nikola; Grazioli, Jacopo; Hering, Alessandro; Germann, Urs; Diendorfer, Gerhard; Rachidi-Haeri, Farhad (2020-04)
      Article
      Restricted access - publisher's policy
      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 ...
    • 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 ...
    • 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 ...
    • Polarimetric radar characteristics of lightning initiation and propagating channels 

      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.; Montañá Puig, Juan; Germann, Urs; Rachidi-Haeri, Farhad (2019-05-27)
      Article
      Open Access
      In this paper we present an analysis of a large dataset of lightning and polarimetric weather radar data collected in the course of a lightning measurement campaign that took place in the summer of 2017 in the area surrounding ...
