ANÁLISE DA FORMAÇÃO DE ILHAS DE CALOR URBANO EM ZONA INDUSTRIAL A PARTIR DE SIMULAÇÃO COMPUTACIONAL

Abstract

Most studies on urban heat islands (UHIs) prioritize densely populated cities, but industrial areas can be considered potential sites for the occurrence of this phenomenon, even with a relatively smaller population. In this study, computer simulation results were presented using the ENVI-met software and the influence of the main parameters that guide the occurrence of ICUs in the canopy layer of the industrial region of São Carlos / SP was analyzed. A section of an area was selected, characterized and classified in terms of local climatic zones (LCZs) and the main properties of construction materials were presented in order to identify their contributions to the urban climate. The input data for the simulation were obtained from climate databases and the results obtained were compared to those measured at the weather station located in the rural area to verify the intensity of the ICU, as well as the verification of published studies and widespread regression formulas. From the analysis of the results and discussion with other studies already published, it was possible to analyze the influence of the main parameters that guide the occurrence of ICUs such as: temperature and relative humidity, wind speed, sky view factor and vegetation cover. The highest intensity of heat island found was 3.4ºC during the night and in the afternoon, a value close to that found in the literature, to be proven through local measurements a posteriori.
