Abstract

The estimation of the air temperature through the modeling of the urban heat islands is an important instrument for the management of the urban space, being possible to contribute to more localized interventions that can soften the atmospheric heat islands linked to the urbanization process. Thus, the procedure of modeling of heat island aims to estimate the air temperature in the surrounding urban and rural environment, where there were no recording points, considering the characteristics of land use and occupation, delimiting the area of each analyzed point. For this, statistical correlations were performed between the measured temperatures at 17 fixed points of records in relation to the surface characteristics, such as vegetation percentage, construction density, sea distance and surface temperatures. The results showed that the model was able to explain about 60% of the temperature variability in the urban area of Ubatuba, located in the North Coast of the State of São Paulo. The temperature distribution in the intra-urban and rural areas was between 23°C and 28°C with the formation of a well-defined heat island in the central area of the city, presenting maximum intensity of 5°C in relation to the rural environment.
