CLIMATE CHANGE IN THE TRIÂNGULO MINEIRO REGION – BRAZILl

Abstract: ABSTRACT:In the summer of 2013/2014 the Brazil's Southern region dealt with a severe crisis in water supply. Recent studies have shown that the low volume of rainfall was caused by an anomalous atmosphere blocking condition. Would this anomaly be a regional effect caused by climate change? To answer this question this study aims to analyze the pattern of temperature, rainfall and relative humidity in the Triângulo Mineiro region, located at the Middle Eastern part of Brazil. Temperature (maximum, average and m… Show more

“…Os autores também demonstraram por meio de teste de análise de covariância (ANCOVA) que existe uma forte relação entre o aumento das temperaturas nos meses de outubro com a redução nos valores de pluviosidade e de umidade relativa. Sanches et al (2017) ainda afirmam que a redução das chuvas e da umidade relativa nos meses de outubro, juntamente com o aumento das temperaturas (máxima, média e mínima) possuem relação direta com a permanência de sistemas atmosféricos tropicais sobre o continente brasileiro, provendo um fenômeno descrito por Ambrizzi et al (2009) e Scaife (2017) como Bloqueio Atmosférico, o qual impede a penetração e o avanço dos sistemas polares e de suas Linhas de Instabilidade frontais.…”

“…Rainfall recorded for the whole basin ranged from approximately 1,000 to 1,750mm, with rainy Summer and dry Winter. These values meet the mean rainfall features of Triângulo Mineiro Region (Sanches et al, 2017), which accounts for mean fragility (3), based on the method by Ross (2012). Stream orders were adopted as EEF analysis criterion in Córrego Alegria Basin (Figure 2); in other words, the goal was to identify whether there were differences in environmental features of drainage streams by taking into account their hierarchy in the network.…”
