Avaliação de riscos para tempestades severas na região sul do Brasil

Abstract

This study addresses the development of a risk assessment for severe storms in southern Brazil, with a focus on the occurrence of hail. The justification for this research lies in the region's vulnerability to extreme weather phenomena, which result in significant economic and social losses. The general objective of the work is to provide a spatial and temporal understanding of the occurrence of severe storms, aiming to support more effective disaster mitigation and management measures. The methodology adopted includes the collection and analysis of historical data on hailstorms, the identification and mapping of areas prone to these events, and the application of geoprocessing techniques to build a risk assessment map. The results indicate that the integration of socio-economic and environmental data is essential for an accurate risk assessment, providing a robust tool for managers and authorities in formulating disaster prevention and response policies. It is concluded that implementing mitigation strategies based on the results of this study can significantly reduce the negative impacts of severe storms in southern Brazil.
