O conforto térmico associado às variáveis de cobertura da terra na região central de Juiz de Fora – MG

Abstract

The current dynamics of urbanization results in advance of anthropogenic environments on the natural environment, which produces an essentially urban climate, which is characterized by imbalances that can be harmful to human comfort and even health. Thus, it is necessary, therefore, studies to evaluate the thermal conditions of this changed environment, besides to the investigation of those responsible for these changes. It also is beneficial to develop methods able not only to map, but to understand the generating spatial patterns of these different comfort zones. Thus, the objective of this research is to identify patterns and processes related to the use of land, climatic factors and growth and urban density, as a contribution to the formation of comfort zones, stipulated by Effective Temperature Index in wind function (TEv ). Finally, this work also aims to provide subsidies to the urban / environmental planning of the city. The research took place in the central region of Juiz de Fora, which covers 12 urban areas, which had processing of data collected in the field and secondary data through GIS tools. As a result it was found different areas of thermal comfort in the Central Region, linked to conditions of densification, showing shaded areas, which could generate attenuation in temperature, but the wind, which owned a decisive role in comfortable conditions and even discomfort.
