Análise termohigrométrica pós intervenções urbanas em Cuiabá-MT

Abstract

Urban densification and suppression of vegetation are determining factors in the modification of the thermo-hygrometric behavior of an urban area. Thus, this research had as general objective to analyze the influence after urban interventions in the microclimate of the city of Cuiabá-MT, for which the data recorded in the four seasons of the year in 2011-2012 and 2016 were used. The air temperature and relative humidity data were compared and the differences found in the soil cover were analyzed in 19 fixed points of the city, divided into two transects. In Transect 1 with 10 fixed points, there was an increase of 2.86 ° C in the intensity of the heat island pointed by SANTOS (2012) and a decrease of 6% of relative humidity of the humid areas, when compared to the Between the years. They are associated to points that presented the highest averages of increase of impermeable cover and decrease of vegetal cover. However in Transect 2, it was emphasized the configuration of freshness and humidity island in P17, located in front of the Massairo Okamura urban park, with a decrease of 2.68 ° C in air temperature and an increase of 7.43% in relative humidity In relation to the more heated and dry areas, when compared between the years. Therefore, urban interventions occurred between 2011-2012 and 2016 should be considered, as there were changes in the thermohygrometric behavior on a microclimatic scale due to the thermal amplitudes observed, associated with the areas coated with impermeable materials.
