Estudio estadístico de las estructuras eléctricas en Castilla y León

Abstract

We present a preliminary statistical study of electrical discharges in the Spanish region of Castilla y León during a 5 years period, from May 2001 to May 2005. The data were obtained from the network of discharges operative at the INM and available in the Mcidas system. The total number of analyzed days is 405, and due to the orographical diversity and large extension, the region has been divided in 23 geographic areas. These zones coincide with those used in operational weather forecasting and are based on the topographical layer of the GSI. We have analyzed the spatial and temporal cloud to ground lightning distributions and their dependence on altitude and mean values of temperature and wind.
