    This paper presents simulations of a downward negative leaders performed by means of 3D finite element method (FEM). The leaders are considered do progress vertically leaders in which different charge distributions and ...
  • A propagative model for simulations of electric fields produced by downward leaders 

    Hermoso Costa, Juan Ramón; Montañá Puig, Juan; March Nomen, Víctor; Van der Velde, Oscar Arnoud; Solà de las Fuentes, Glòria; Romero Durán, David; Hermoso Alameda, Blas; Pineda Rüegg, Nicolau (2012-07-13)
    Article
    Open Access
    Comparisons of simulated downward negative leaders with experimental measurements are presented in this paper. In order to simplify, the leaders are considered to progress vertically and charge distributions and leader ...
  • A simple method to estimate the return stroke current from close electric field measurements 

    Montañá Puig, Juan; Illa Arnau, Àngel; Hermoso Alameda, Blas; Romero Durán, David (2004)
    Conference lecture
    Restricted access - author's decision
    During summers 2003 and 2004 a measurement campaign was carried out over Catalonia (N-E of Spain). In these campaigns, lightning electrostatic field as well electric and magnetic fields were measured. This paper describes ...
  • Basic lightning flash properties derived from lightning mapping array data 

    Montañá Puig, Juan; Pineda Ruegg, Nicolau; Van der Velde, Oscar Arnoud; Solà de las Fuentes, Glòria; Argemí Ribera, Oriol; Fabró Tàpia, Ferran; Romero Durán, David; Aranguren Fino, Daniel (2016)
    Conference report
    Open Access
    The size and duration of lightning flashes are examined. Data from the Ebro Valley Laboratory Lightning Mapping Array is used as reference. Additional data from the VLF/LF LINET network is included. In the analysis, each ...
  • Behaviour of the windmill under lightning strikes including nonlinear grounding system 

    Montañá Puig, Juan; Candela Garolera, Anna; Romero Durán, David (2004)
    Conference lecture
    Restricted access - author's decision
    The grounding behaviour is a critical aspect in a windmill lightning protection system because can appear sparks due to a higher surge and damage parts of the windmill [1][2]. This paper proposes a model to a lightning ...
  • Charge structure of two tropical thunderstorms in Colombia 

    López Trujillo, Jesús Alberto; Montañá Puig, Juan; Van der Velde, Oscar Arnoud; Pineda Rüegg, Nicolau; Salvador Yuste, Albert; Romero Durán, David; Aranguren Fino, Harby Daniel; Taborda, John (2019-04-23)
    Article
    Open Access
    Charge structure derived from lightning leader development of tropical thunderstorms comprising equatorial latitudes of < ±10° has not been investigated yet. In this work, using a Lightning Mapping Array (LMA) installed ...
