Abstract

Curitiba is recognized for its urban planning. However, due to rapid urban growth in the last decades, the city developed both vertical and horizontally, exceeding its limits towards neighboring cities forming the Urban Agglomerate of the Metropolitan Region of Curitiba (AU-RMC). Curitiba, the coldest capital of Brazil, presents thermal discomfort due to cold temperatures during most of the year, mainly in the winter, what causes problems for its population. It’s urban climate exhibits considerable variability; city areas alternate between cool and heat islands, which results in different thermal comfort/discomfort levels. This research is based on the theoretical-methodological and verifies the relations between society/nature, space/time (climate) and global/local interaction. From the cartography of the area, the urban facts and their correlation, a spatial sectorization of the city was elaborated, which guided the generation of the monitoring network in the field. In parallel, the temporal analysis resulted in the characterization of the local climate under the dynamic aspects of the atmosphere and in the experiment’s contextualization. A representative winter day was chosen (August, 21st. 2006). Surface Thermography, obtained by Landsat 5 satellite image, allowed a detailed investigation of the intra-urban climate regarding surface temperature and its influence on air temperature. Climatic data was collected in situ in 16 selected sites. Confronting the thermal discomfort degrees with life conditions and life quality at the sampled sites, a coincidence of a double discomfort was verified: by cold and by larger thermal amplitudes, specially where poverty was established, due to urban socio-spatial configuration. This aggravates low life quality indexes and socio-environmental vulnerability due to urban climate in winter.
