Computer Simulation of Three Mesoclimatic Urban the Federal District of Brazil

This work it is an analysis of the current bioclimatic context of Federal District (FD), using as a methodological tool the ENVI-met software for simulation of the current situation, looking in contrast the three inserted mesoclimatic areas in the district and its different configurations Urban: Planaltina (FD Northeast), Sudoeste (FD Center area) and Ceilândia (FD Southwest). The objective is to compare the urban settings of the three regions and analyze the thermal differences that contribute to the formation of heat islands. The FD goes through an accelerating process of urbanization. So, the urbanization impacts directly on the urban climate, negatively affecting the quality of life of the inhabitants. In this sense, the monitoring of environmental quality is tool to solve the problem of urban climate. The methodology is comparative, through computer simulation with the ENVI-met software. The study deals with how different urban designs found in the three regions of the FD mesoclimatic contribute to the generation of heat islands. The results show that in Ceilândia and Planaltina (northern and southern regions of the FD) thermal amplitude reaches 5°C at certain times of the day, while in the Sudoeste district values are milder. One can therefore say that the border cities of the FD are more susceptible to the formation of heat islands, since the urban design is a pocket built with low afforestation rate.
