Abstract:

this paper discusses the influence of urban morphology on air temperatures along the avenues alberto andaló and josé munia, in s?o josé do rio preto. four places in those avenues were chosen for thermal data collection - both are located along the canela stream,. the results revealed temperature differences between the four points. the study used maps containing cadastra and morphological data, such as land use, topography, configuration of blocks and lots, building heights and ground cover, either developed by the local authority or obtained from satellite imagery and field observation. the relationships between these data and the characteristics of land use and occupation showed a significant decrease in air temperatures during the night, due to the presence of vegetation and soil permeability, reducing heat islands. conversely, areas with high occupancy of buildings and intensely paved areas and blocks lost less heat, leading to the formation of the highest urban heat islands during the night period.
