ILHAS DE CALOR NA CIDADE DE SÃO CARLOS, SP

ANÁLISE DO CAMPO TÉRMICO ATRAVÉS DE MAPAS DE DISTRIBUIÇÃO DA TEMPERATURA DO AR E UMIDADE RELATIVA

Abstract

This article represents a study about the formation of urban heat islands in the city of São Carlos, SP, through the elaboration of maps of the distribution of air temperature and relative humidity. These two climatic variables were collected in four measurements during four seasons of the year of 2017. The measurements were performed during 15 days in 10 points in each period, totalizing 36 points with different urbanistic characteristics. In order to compare the data registered in different seasons, the data was normalized and extrapolated in relation to the reference point, where the measurements were realized in all the seasons. Based on these values, maps of distribution of air temperature and relative humidity were elaborated. Further, the intensity of urban heat island was calculated, as a difference between temperatures in urban and rural environment. The results show that the most elevated temperatures and lowest humidity were registered in densely built points, with the predominance of impermeable coatings and little vegetation. Works like this, which seek to understand environmental aspects of urban growth, are very important for medium-sized cities, such as São Carlos, considering that these cities are still in the phase of growth and can utilize guidelines for a more sustainable development.
