O clima no espaço intra-urbano do distrito sede de Aquiraz-CE na perspectiva termodinâmica: episódios sazonais contrastantes

Abstract

This research was conducted in the urban core of the district headquarters town of Aquiraz - CE, located in the Metropolitan Region of Fortaleza, and sought to know the climate dynamics of the area under the thermodynamic level of Monteiro's SCU (2003). The aim of this study was to diagnose the thermal and hygrometric differences under different conditions of use and occupation of the soil. This we noticed how these different are reflected in the thermal comfort in the microclimatic scale of the urban core on the representative days of the contrastive seasons. The study was conducted in four experimental points that present different urban dynamics and different geoecological characteristics. Data collection occurred over three representative days of contrastive seasons, with simultaneous measurements in the schedules of 6, 9, 12, 15, 18 and 21 hours. The first experiment was carried through on April 16, 2011, corresponding to the rainy season. The second occurred on August 20, 2011, corresponding to the dry season with strong intensity of the winds and the third occurred on November 26, 2011, the representative day of dry period with low intensity of the winds. The results demonstrate the climate dynamics of the sazonais periods in which they were measured, and the atmospheric circulation systems act as determining factors in the behavior of climatic attributes. The thermal and hygrometric observed contrasts were significant for the reality of the urban core of the district headquarters. The data collection points of intense urban dynamics and density of buildings were those with the highest temperatures, and a more wooded point showed the lower temperatures, higher humidity and consequently favorable conditions for thermal comfort.
