Variações microclimáticas no centro de Juiz de Fora - MG: uma análise dos padrões de temperatura do ar e sua relação com o desenho urbano

Abstract

The temperature increase related to urban centers tends to be exacerbated in the coming years due to climate change, directly affecting people's quality of life. I aim to compare the influence of land use and occupation on air temperatures in four points in the central area of the city of Juiz de Fora. Firstly, I did a literature review that defined and guided different concepts used to support the work. In addition, air temperatures were measured at four points at 8am, 1pm and 7pm, for ten consecutive days in the months of December 2022 and July 2023. The data from the three times were subjected to Analysis of Variance (ANOVA) and the Tukey test to check possible statistically significant differences. Thermal Potential mapping was also developed for the four points considering the vegetation mass, urban canyon, built mass, permeability, albedo and emissivity as variables. The results found indicated warmer temperatures on Avenida Getúlio Vargas and milder temperatures in Parque Halfeld. The temperature collection presented results partially in accordance with the Thermal Potential Model, which indicated that Avenida Getúlio Vargas has less heating potential than Avenida Rio Branco, for example. Finally, intervention proposals are made aimed at implementing vegetation and the urban microclimate, in the four points analyzed. The proposals fit into different urban compositions and scales, such as green walls, urban trees and green roofs – according to the possibilities and the local landscape.
