| Abstract | |
The present research aimed to analyze the formation of Urban Heat Islands in São Luís, capital of the state of Maranhão, considering the dynamics of urban space, the physical and environmental characteristics and the different forms of land use and occupation. The heat islands can be characterized by the difference in temperatures of a closer rural environment to the other environments of the urban area. For the development of the research, the theory of the Urban Climate System (UHS), proposed by Monteiro (1976), was used, particularly in the thermodynamic subsystem that involves data regarding the temperatures observed and spatially distributed in the city, considering mainly the urban heat islands and the intra-urban structure. In order to achieve the objectives, the research was divided into three different but complementary stages, such as: identification and characterization of the urban environment; analysis of surface heat islands through remote sensing; and analysis of atmospheric urban heat islands based on temperature records at fixed points. Satellite Image Digital Processing techniques were used, descriptive statistics for initial understanding of the dynamics of urban temperatures, analysis of temperatures for the study of intensities and magnitudes of atmospheric heat islands. As results, the surface heat islands showed higher temperatures in the most densely built areas, and the lowest were recorded in areas related to Conservation Units, Permanent Preservation Areas or areas that have a higher level of afforestation due to housing patterns. Atmospheric heat islands presented higher intensities in the daytime period. In the nighttime period there is a pattern of low differences in UHI intensities. The magnitudes found were of low, medium, strong and very strong magnitude, being that those of weak magnitude were predominant in the studied period (76.5%). (AU) | |
