Relação entre componentes naturais e urbanos e características do campo térmico para definição de topoclimas no município de Juiz de Fora - MG

Abstract

Climatology research in medium-sized cities is important to maintain environmental quality. In this sense, the objective of this article was to bring data and information about the identification and characterization of the thermal field in the city of Juiz de Fora (Minas Gerais – Brazil), considering the variations of air temperature and relationship with land use and land morphology aspects, for the elaboration of climate units sketch. Methodological procedures included theoretical review, analysis of remote sensor thermal conditions, acquisition and treatment of field data, spatial data processing and data synthesis. The results showed that the eastern portion of the municipality recorded the lowest values of air temperature, related to the presence of vegetation fragments and waterways, and the point with the lowest average temperature was identified in the rural area, in a riparian forest fragment. The maximum temperature was located in the Industrial District. The 34 topoclimatic classes identified resulted from existing combinations of temperature, land use and terrain morphology. The class of land use associated with pasture areas has great relevance in the constitution of the thermal zones of the municipality.
