Influência térmica das configurações urbanas ao longo do eixo do Córrego Canela na cidade de São José do Rio Preto

Abstract

This research intends to investigate the influence of urban morphology in air temperature along the axis of Alberto Andaló Ave. and José Munia Ave., which border the Canela Stream in São José do Rio Preto. Initially, a review was made on the relationship between urban design and the influence of climate and vegetation on climate. Alongside, it was made a review of some existing studies on the expansion of the city, as well as on the occupation of streams margins by avenues construction. The cadastral and morphological data such as land use, topography, configuration of city blocks and lots, height of buildings and ground cover were surveyed in maps, either developed by the Municipality or obtained from satellite imagery and field observation. In order to collect temperature data, four points were chosen - two in José Munia Avenue and two in Alberto Andaló Avenue. The results of that field campaign at two measurement periods - the first in April and the second in July and August - revealed differences in the air temperature among the two avenues. The correlation of these data with the characteristics of land use and occupation showed a significant decrease of air temperature during the night due to the presence of vegetation and soil permeability, thus, minimizing the heat islands. Also, it was found that areas with high occupancy of buildings and intensely paved areas and city blocks lost less heat, leading to the formation of the highest heat islands during the night period.
