Uma Análise Visual da Espacialização das Descargas Elétricas Atmosféricas e do Comportamento das Mortes Causadas por Raios no Estado da Bahia

Abstract

Studies released by the Atmospheric Electricity Group of the National Institute for Space Research place Brazil as the country with the highest incidence of lightning in the world, with an average of 77.8 million every year. In the period from 2000 to 2019, 2,194 deaths from lightning were recorded in the country, with every 50 deaths from lightning in the world, one is in Brazil. The objective of this work is to carry out a visual analysis of the behavior of lightning strikes in the state of Bahia, relating it to the number of deaths caused by lightning in each municipality. The goal is to investigate whether there is any relationship between the number of deaths, the region and the population.To this end, data on lightning density density and number of deaths caused by lightning were published by INPE and the Ministry of Health, respectively. The number of inhabitants provided by IBGE in each municipality in the state of Bahia was also used. Visual analysis was performed using the VYR tool. The results showed a higher incidence of discharges in the western region of the state. As for the number of deaths, there was a homogeneous distribution in the state, with an apparent relationship with the number of inhabitants of the municipalities. There was a reduction in the number of deaths in the last ten years, probably related to the increase in the education level of the population.

“…A combinação do relevo, hidrografia local, clima tropical além de períodos chuvosos e de seca bem definidos 9 , formam um cenário favorável para uma maior incidência de descargas elétricas (Barretto; Novais; Barbosa, 2021).…”
