Lightning detection in Poland is performed by means of a PERUN (Safir 3000) system operated the Institute Meteorology and Water Management. also partly covered VLF/LF lightning (CLDN, Central Detection Network). Both sources data have their limitations resulting from technique, limited number sensors geographical configuration, with consequence shortcomings quality. For this reason, new network has been installed started continuous real-time operation May 2006. It LINET that covers entire...
The aim of this paper was to show usefulness Power Spectrum Density analysis for identification different components IC lightning. We have presented some exemplary pulse train electric field recordings characterized the specific time development intra-cloud lightning discharges observed during summer thunderstorms in Poland. These data were gathered by two detection stations working independently Warsaw and Rzeszow. Both are based on triggered acquisition ELF-MF frequency range. Such...
The aim of this paper is modeling and parameter identification the leader stage preceding positive stroke natural cloud-to-ground lightning. This research based on electric field 3D Doppler radar data recorded during thunderstorms in Poland, as supplied by database information from long range lightning location systems. numerical simulation performed MATLAB platform showed that a high number assumed model parameters, such non-uniform tip speed channel charge density, allowed us to obtain...
Abstract We compare the results of two methods calculation charge moment change (CMC, also called dipole change) cloud‐to‐ground lightning discharges. The first method uses multistation ground‐based measurements E field for purpose flash location and analysis. Our six stations, Local Lightning Detection Network (LLDN), were set up in Warsaw region. second is based on horizontal magnetic component electromagnetic waves generated by atmospheric discharges ELF (extremely low frequency) range....
This paper is aimed to show how detect and identify the lightning stepped leader stage from power spectrum density spectrograms (PSD) of related electric field records. Such records were obtained local detection system operating in Rzeszow region. consists two slow fast sensors working ELF ELF-MF frequency range, respectively. Additionally, development corresponding flash channel can be recorded by digital high speed video camera. The bandwidth antenna enable us recognize properly all main...
The paper presents the results of spatial location (in coordinates local and rectangular Cartesian system: x, y, z) as well polarity electric charge all sources in thunderclouds discharged by individual return strokes during 17 multiple cloud-to-ground discharges recorded simultaneously six measurement stations LLDN (Local Lightning Detection Network) system located Warsaw region spring summer season 2009.The post-time analysis collected digital field records these was carried out based on...
