Avaliação de parâmetros micrometeorológicos, do conforto e da percepção térmica na área urbana da cidade de Belém-PA

Abstract

In the present study evaluated a micrometeorological elements and thermal comfort in Belém, along with an examination of issues of social segregation of urban space, contributing to the research of urban climatology in tropical regions that have a specific climate with a strong effect of seasonality during the year. Were used in the research information obtained by weather stations and microloggers distributed by the city, questionnaires, land cover information derived from satellite images and social typologies of urban areas through literature. Quantitative information was analyzed through numerical interpolations and correlations qualitatively and related information acquired in the field. The results indicated that the areas were the less comfortable heat that had less vegetation cover and greater amount of built and paved areas, while areas more comfortable showed the characteristics contrary to earlier, where it was detected the absence of a standard well defined between the socio-spatial typologies with comfort conditions. There was low heat island intensity on the city as well as strong seasonality of rainfall, air temperature and relative humidity. In the city of Belém much of the daytime was uncomfortable, and the intensity of discomfort varied with the characteristics of use and occupation of urban land.
