O clima urbano em Penápolis/SP : análise da temperatura e umidade intraurbana /

Moreira, Janaína Lopes. January 2016 (has links)
Orientador: Margarete Cristiane de Costa Trindade Amorim / Banca: José Tadeu Garcia Tommaselli / Banca: Maria Elisa Zanella / Resumo: A cidade se consolidou como local de morada de grande parte da população mundial no século XX. Segundo a ONU, desde 1990, o mundo tem visto um incremento na concentração da população nas áreas urbanas. Esse aumento pode ser associado aos processos de urbanização mais recentes ocorridos em alguns países, tais como os localizados na América Latina e Caribe, que entre 1950 e 1990 viram suas populações urbanas crescerem de 40% para 70%. No Brasil, esse fenômeno se manifestou principalmente através da apropriação do campo pela produção capitalista, que gerou grande êxodo rural e rápido crescimento populacional nos centros urbanos. Fato que foi determinante para o agravamento das mazelas urbanas, e consequentemente, para as condições de vida e a atual configuração das cidades brasileiras. Dentre os problemas ambientais urbanos provenientes desse processo, destacam-se os referentes à atmosfera urbana, tais como o acúmulo de calor, poluição e inundações, que têm causado desconfortos e prejuízos à qualidade de vida dos citadinos. Nesta perspectiva, o objetivo desse estudo foi detectar o fenômeno de ilha de calor em Penápolis/SP e suas magnitudes, considerando-se seus atributos geoambientais e geourbanos. A pesquisa teve como referência a teoria do Sistema Clima Urbano proposta por Monteiro (1976), com ênfase no que o autor denominou de subsistema termodinâmico. Os procedimentos metodológicos realizados se basearam na realização de transectos móveis, na instalação de dois pontos fixos ...

According to ONU, since 1990, the world has seen an increasing concentration of population in urban areas. This increase can be associated with more recent urbanization processes that occurred in some countries, such as those located in Latin America and the Caribbean, which urban population grew from 40% to 70% between 1950 and 1990. In Brazil, this phenomenon manifests itself mainly through the appropriation of field sites by the capitalist production, which led to a large rural exodus and a rapid population growth in urban centers. That circumstance was crucial to worsen the urban issues, and consequently, the living conditions and the current configuration of Brazilian cities. Among the urban environmental problems arising from this process, we highlight those related to the urban atmosphere, such as heat storage, pollution and flooding, which have caused discomfort and damage to the quality of life of residents. Therefore, the objective of this study was to detect the generation of the heat island and its intensity in the city of Penápolis/SP, considering the land use, land cover and urban built form. The research was based on the Urban Climate System theory proposed by Monteiro (1976), focusing on what the author called "thermodynamic subsystem". The methodologies included mobile traverses, installation of two fixed stations, satellite images and remote sensing techniques. Satellite images were used to map the environmental and urban characteristics, such as vegetation, relief, surface temperature and building density. The selection of the two fixed points was based on bibliographical references, one located in downtown, a high-density area, and other situated in the rural area, both with similar altitudes ...
