Abstract

This research project aims to build a tool that can compute the probability to have a lightning discharge or not in time in a given specific place, in order to reduce socio-economic impacts as well as life due to lightning activity. Additionally, by computing the probability of not lightning risks or treats, it will be possible to guarantee the return of activities without compromising the production and the security of people and goods. The goal of this project is to develop a software that automatically operates a methodology that computes lightning warning based on existing 3 technologies in a given area available in the market: lightning locating systems (SLT), electromagnetic slow antennas (SREVL) and electrostatic field mills (SCE). In the first phase, this project will use a lightning database measured previously by STORM-T Laboratory of USP and public available, i.e., the South American lightning detection network - STARNET (SLT) and the coincident measurements from field mills sensors (SCE) and slow antenna intra-cloud and cloud-to-ground counter (SREVL). By combining these 3 technologies it is possible to emit warning for distant thunderstorms as well as thunderstorms the form locally and that are not electrically active and detectable. The warnings are based on the lightning activity detected by the different technologies (number of intra cloud and cloud to ground strokes, thunderstorm distance, thunderstorm speed and propagation direction, flash rate and temporal flash rate) and the temporal variations of the local vertical electrical field. The software will be configured to compute the probability of occurrence or not of lightning even with one technology. Therefore, this methodology can be applied to any place that has access to at least on technology available. (AU)
