Análise do comportamento termo-higrométrico urbano sob a ótica do uso e ocupação do solo em Cuiabá - MT

Abstract

Many cities have based their growth and development in expansionist designs, which are not sustainable from an environmental perspective, currently showing significant signs of degradation. The impacts of warming in cities have consequences as increased rainfall, drought and destruction of natural ecosystems. The climate of Cuiabá is AW second Koppen (high temperatures, rain in summer and dry in winter). It is noticed to urban growth, removal of vegetation cover, the channeling of rivers and streams, and soil sealing, further aggravating the local microclimate conditions. This work aimed to make a study on three neighborhoods, Good Hope, Santa Cruz and Garden College, the choice of them, was due to their morphological features still having area of native vegetation is proximity the River Coxipó. Micrometeorological data collections were performed by automated stations (24h) and mobile transect (8a.m., 2p.m. and 8p.m.) in two hot-dry and hot-humid periods. In these periods the differences in air temperature between the points range from 0,9°C to 3,7°C and relative humidity between 1,8% to 10,6%. In the analysis considering only the characteristics use and land cover the temperatures have had a change of 0,1°C to 0,4°C. Thus we note that it is not only the urban occupation that is responsible for microclimate, but several factors to a greater or lesser extent corroborate the climate performance of each site. The urban canyon factor was also considered in study representative of the microclimate performance because this factor may be responsible for the amount of incident solar radiation, and thus heating. The present study only few of the many issues surrounding the urban climate. The contribution is pointing out some specific problems which succeeded due to the growth of CuiabáMT that need to be considered by planners and managers so that measures to improve environmental quality are taken in order to have a more sustainable city.
