Esta dissertação examinou dados climáticos de temperatura em Bragança, utilizando a
rede meteorológica do Instituto Politécnico de Bragança (IPB) instalada na cidade,
composta por 23 sensores (dos quais 21 foram utilizados na análise). O objetivo principal
foi analisar os dados de temperatura do ar, com foco no Efeito de Ilha de Calor Urbano
(EICU), durante o período de 2013 a 2022, totalizando 10 anos de dados. A metodologia
incluiu a correção altimétrica dos dados, técnicas de médias móveis, análises dos efeitos
de ilha de calor urbano e análise estatística por Correlação de Pearson. Foram avaliados
padrões sazonais, tendências temporais e anomalias climáticas, como noites tropicais e
dias com temperaturas máximas acima de 35°C, dias frios e noites frias. Os resultados
apontaram uma maior intensidade do EICU nas ZCLs mais urbanizadas, com intensidades
significativamente elevadas durante o verão. Foi notável o Efeito de Ilha de Frio Urbano
(EIFU), que ocorre com maior intensidade nas estações quentes. A análise de médias
móveis e de tendências indicou um aumento gradual de 1,5°C na temperatura do ar ao
longo do período estudado, atribuível tanto à urbanização quanto às mudanças climáticas
globais. O ano de 2022 destacou-se como o mais quente da série analisada. Através desta
dissertação, concluo que a urbanização intensifica o EICU e exacerba os eventos
climáticos extremos, impactando diretamente a qualidade de vida urbana. Reforça-se a
importância de políticas públicas voltadas para o aumento de áreas verdes e o uso de
materiais que minimizem a retenção de calor, promovendo cidades mais sustentáveis e
resilientes. O estudo contribui para os Objetivos de Desenvolvimento Sustentável (ODS),
destacando a interseção entre saúde, bem-estar e ação climática no planeamento urbano.
This dissertation examined climatic air temperature data in Bragança, utilizing the meteorological network of the Polytechnic Institute of Bragança (IPB) installed in the city, comprising 23 sensors (21 of which were used in the analysis). The primary objective was to analyze air temperature data, focusing on the Urban Heat Island Effect (UHIE), over the period from 2013 to 2022, encompassing a total of 10 years of data. The methodology included altitude correction of the data, moving average techniques, analyses of urban heat island effects, and statistical evaluation using Pearson Correlation. Seasonal patterns, temporal trends, and climatic anomalies were evaluated, such as tropical nights, days with maximum temperatures above 35°C, cold days, and cold nights. The results indicated a higher intensity of the UHIE in the more urbanized Local Climate Zones (LCZs), with significantly elevated intensities during the summer. The Urban Cool Island Effect (UCIE) was notable, occurring with greater intensity during the warm seasons. The analysis of moving averages and trends indicated a gradual increase of 1.5°C in air temperature over the study period, attributable to both urbanization and global climate change. The year 2022 stood out as the warmest in the analyzed series. Through this dissertation, it is concluded that urbanization intensifies the UHIE and exacerbates extreme climatic events, directly impacting urban quality of life. The importance of public policies focused on increasing green areas and using materials that minimize heat retention is emphasized, promoting more sustainable and resilient cities. The study contributes to the Sustainable Development Goals (SDGs), highlighting the intersection between health, well-being, and climate action in urban planning.
