Influência da ocupação do solo na variação termo-higrométrica na cidade de Cuiabá-MT

Abstract

The large clusters of urban areas tend to create a new urban climate generated by the interference of factors that occur on the urban boundary layer and that act by altering the climate on a local scale. The urban characteristics associated with the types and degrees of density and use that cover the soil have the ability to modify the climatic elements that make up the local atmosphere. Thus, this study aimed to analyze the influence of land use on the microclimate in Cuiabá-MT-Brazil through the differences in temperature and humidity intraurbana the municipality. To that end, we used the methodology of mobile transects in four night season, using a digital thermohygrometer, protected shelter, attached to the side of a vehicle that left the rural outskirts, passed through the center and reached the other side of town , in the east / west and then north / south. Records were set to 20h, thermo-hygrometric for analysis and detection of climate anomalies such as heat island, showing the influence of anthropogenic changes in the urban environment. The urban density and the removal of vegetation are key factors in behavior modification thermohygrometric, it is evident the influence of the flow of vehicles in the heat gains in the middle, while areas under the influence of large masses of vegetation, had its own characteristics, with microclimate various other areas of the city, since there is a contribution to the energy loss to the middle and fall in temperature and increase in relative humidity. Therefore, this study contributes to diagnose any changes in urban climate due to the growth process of Cuiabá, which need to be considered by planners and managers to be taken to help with the improvement of environmental quality and people's lives.
