| dc.description.abstract | In this research are characterized several parameters (temporal and magnitude) of the electric field signatures of the initial preliminary breakdown pulses (PBP trains) that precede the first return stroke (FRS), generated by cloud-to-ground (-CG) lightning flashes mostly occurred in the Bogotá savannah (central region of Colombia). The signatures are identified in more of 160 lightning flashes, during the second and first thunderstorms season in 2017 and 2018, respectively. The parameters of the PBP trains were characterized employing some statistical measurements, such as geometric mean (GM) and arithmetic mean (AM). Additionally, this study analyzes the relationship of the parameters of the train PBP with some factors that influence the distribution of electric charge of the thunderclouds (weather conditions, time of year, geographic location, etc.). Finally, the statistical indicators obtained in this research were compared with the reported in other works made in different regions of the world. | spa |

Las formas de onda son identificadas en más de 160 rayos, durante la segunda y primera temporada de lluvias del 2017 y 2018, respectivamente. Los parámetros de los trenes PBP fueron caracterizados empleando varios indicadores estadísticos, tales como la media aritmética (AM) y media geométrica (GM). Adicionalmente, este estudio analizó la relación de los parámetros de los trenes con algunos factores que influyen en la distribución de carga eléctrica de las nubes de tormenta (condiciones meteorológicas, época del año, ubicación geográfica, etc.). Finalmente, los indicadores estadísticos obtenidos en esta investigación fueron comparados con los reportados en otros trabajos hechos en diferentes regiones del mundo. | spa |
