Análise termohigrométrica de porção urbana em função da morfologia e revestimentos do solo na cidade de Cuiabá-MT

Abstract

Since the beginning, human beings have tried to understand the natural events and the environment that surrounds them. On the other hand, the search for knowledge about the relationship between man and the environment is recent. With urbanization and the suppression of vegetation, cities have faced new challenges regarding the behavior of the materials used, such as concrete and asphalt, for example, and how they act in the microclimate of these environments, which directly affects the quality of life of people using these spaces. . Thus, the objective of this work was to analyze the thermo-hygrometric behavior of an urban area in the city of Cuiabá-MT, in 2018, considering the soil covering materials at each of the nineteen data collection points chosen. Analyzing variables such as air temperature, relative humidity, surface temperature of the soil covering at the given point and the percentage of covering, an urban microclimate profile was drawn and the influence of these materials on the characterization of these microclimates. As a result, it was observed that in the points with more use of urban materials such as concrete and asphalt, higher air temperature and lower relative humidity were obtained. In the points where there were more green areas, a higher relative humidity of the air and a milder temperature were observed in relation to the more urbanized points. It was also observed that asphalt has greater thermal gain than concrete, when both are subjected to direct sunlight. Thus, it can be concluded that green areas in cities tend to act on climatic elements, contributing to the control of solar radiation, air temperature and humidity, wind and rain. It is expected that with the results of this research, it will be enriched the study of the influence of different soil covering materials in the state of Mato Grosso and the Midwest region, paying attention to the importance of green or shaded areas as mitigating agents of climatic rigor imposed by the climate of medium-sized cities, such as Cuiabá-MT.
