ANALISE DO CAMPO TÉRMICO DA CIDADE DE IRATI/PR: PRIMEIROS EXPERIMENTOS PARA A DEFINIÇÃO DO CLIMA URBANO.

Abstract

This work deals with the urban planning of cities to medium-sized and small, inparticular, examines the formation of urban thermal field analysis based onclimate. The city of Irati, located in south-central portion of Parana State, is theobject of this study. Considering the theoretical references on which the subject,both in terms of more general (urban planning), and in particular (urbanenvironment), was made a preliminary survey of the essential characteristics ofthe urban site of the city concerned. After the survey, were selected fromcollections of data points of temperature at 12 locations, which were monitoredby the academic progress of Geography of Unicentro in the period from 23 to 30April 2008. The physical characteristics of the city showed a slopinggeomorphology with guidelines for different sections, showed no uniformpattern. Moreover, the socioeconomic conditions show that the urban density isconcentrated in the central area of the city, with a low occupancy in peripheralareas, at least with regard to sealing of soil. Thus, the 12 items selected forcollection of data allowed the analysis of different social realities of the city,which examine the influence of urban dynamics in the temperature change. Theanalysis of results and conclusions have identified the formation of heat islandswithin the study area; in principle, the hottest area is located in the central city,but at the same time at night, it is an area without distinction to yoursurroundings and even presenting values of temperature that induce theformation of a cooling island. The influence of urban structure in the spatialvariability of air temperature was examined, although there are still doubtsabout the genesis, because the physical factors (topography, vegetation andwater) seem to influence both on the urban structure in their formation. Forgreater certainty as to the study, new experiments should be conducted, usingdifferent methods and methodologies, seeking a better explanation for thevariation of climatic elements in the city of Irati.
