Resumo: | Recent studies in the Amazon area show that urbanization is the most impacting factor in microclimatic patterns, contrasting with the reduction of vegetation cover, the most relevant element for maintaining thermal comfort. The objective of the investigation is to analyze the variation of the thermal comfort index in the city of Macapá-AP under the influence of land use and occupation, especially in relation to the reduction of vegetation cover. The investigation methodology consisted of the analysis of the effective temperature index and the heat index as predictive factors of thermal comfort during three distinct seasonal periods: rainy (April/2018), dry (November/2018) and transition (June/2019). For this purpose, five urban sites were strategically chosen and carefully distributed along the Northeast-Southwest and West-East axes of the city, using the technique of supervised classification and monitoring of time series of average temperature and relative humidity. The results suggest that the most vegetated areas avoid the extrapolation of the limits of the thermal comfort indices (p<0.05), confirming similar results in the literature recorded in other Amazonian cities. Thus, the Effective Temperature Index ranged between comfortable and uncomfortable and the Heat Index ranged between comfortable and cautious, presenting considerable space-seasonal thermal amplitude. |

O objetivo da investigação é analisar a variação do índice de conforto térmico na cidade de Macapá-AP sob influência do uso e ocupação do solo, especialmente em relação à redução da cobertura vegetal. A metodologia de investigação consistiu na análise do índice de temperatura efetiva e Índice de calor como fatores preditivos do conforto térmico durante três períodos sazonais distintos: chuvoso (abril/2018), seca (novembro/2018) e de transição (junho/2019). Com esse propósito foram escolhidos estrategicamente cinco sítios urbanos geográfica e criteriosamente distribuídos ao longo dos eixos Nordeste-Sudoeste e Oeste-Leste da cidade, usando a técnica de classificação supervisionada e monitoramento de séries temporais da temperatura média e umidade relativa do ar. Os resultados sugerem que as áreas mais vegetadas evitam a extrapolação dos limites dos índices de conforto térmico (p<0,05), ratificando resultados similares da literatura registrados em outras cidades amazônicas. Assim, o Índice de Temperatura Efetiva variou entre confortável e desconfortável e o Índice de Calor variou entre confortável e cautela, apresentando amplitude espaço-sazonal térmica considerável.EDUFU - Editora da Universidade Federal de Uberlândia2023-06-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/6564910.14393/RCG249365649Caminhos de Geografia; Vol. 24 No. 93 (2023): Junho; 01-17Caminhos de Geografia; Vol. 24 Núm. 93 (2023): Junho; 01-17Caminhos de Geografia; v. 24 n. 93 (2023): Junho; 01-171678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/65649/36156Copyright (c) 2023 Pedro Hugo Oliveira Moreira, Antonio Carlos Lola da Costa, João de Athaydes Silva Júnior, Alan Cavalcanti da Cunhahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMoreira, Pedro Hugo OliveiraCosta, Antonio Carlos Lola daSilva Júnior, João de AthaydesCunha, Alan Cavalcanti da2023-06-15T11:51:05Zoai:ojs.www.seer.ufu.br:article/65649Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2023-06-15T11:51:05Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
