Eventos pluviométricos extremos e desastres naturais em serras úmidas: uma análise em Itapajé-CE no maciço de Uruburetama

Abstract

Studies relating to extreme rainfall events are increasingly relevant, as they have also become more alarming and commonplace. Extremes, which were previously seen as rare events, are currently episodes that occur with greater frequency and greater intensities. The work aims to identify and classify the extreme rain events that occurred in the city of Itapajé - CE over a historical series of 30 years (1993-2023), in addition to specifically analyzing the episode on March 19, 2023, the which caused a sequence of disasters. The methodology used to develop the work and identify events was the Statistical Methodology of Extreme Precipitation Events - M3EP, which identifies the number of extreme events existing within the analyzed series and classifies them into 3 categories: moderate, strong and very strong. For natural disasters, data from Civil Defense was used, more precisely from the Integrated Natural Disaster Information System - S2ID, which provided us with data from 2003 to 2023 on the number of disasters and their classification according to the Brazilian disaster coding. In general, the work makes it possible to observe that the action and occurrence of extremes in humid mountains are becoming increasingly present and more aggressive to communities living in areas more vulnerable to the occurrence of these events.
