    The Metropolitan Region of Greater Vitória (RMGV) is the most industrialized and urbanized area of the state of Espírito Santo. This whole process has led to changes in the local atmospheric circulation, such as the formation and intensification of the urban heat island (ICU). Therefore, the main objective of this research was to study the atmospheric impact due to the alteration of land use and coverage in the Greater Vitória Metropolitan Region. This research will be developed in two stages: the first will be the ICU observational study and the second will be the use of atmospheric numerical modelling, using the Weather Research and Forecasting (WRF) model coupled with the Building Effect Parameterization (BEP) model. The analysis of observational data shows that the maximum hourly intensity of ICU at RMGV was 7.35 ° C at 14h in October 2017 and 7.53 ° C at 15h in January 2018. Despite the values Often, the heat island in the RMGV is less intense than in high and medium latitude areas. It was also observed that the heat island is more intense during the day, in summer, and is associated with the time of higher magnitude of thermal load available in the environment and not that stored by the urban fabric. From the LANDSAT-8 satellite images, it was found that the surface intensities and spatial extensions of the ICU in the RMGV reach extremes -3 ° C to + 20 ° C, presenting an amplitude of + 17 ° C. Values between + 2 ° C to + 8 ° C comprise the largest area, and in urban areas, values of intensity + 5 ° C are commonly recorded. The effects of urbanization in the simulations performed with the WRF-BEP model show that the heat island provided an average 5 ° C increase in air temperature, corroborated by the increase in sensible heat flow and reduction of latent heat, as well as, favoured an increase of Bowen's ratio up to 10 times. The heat island also favored an increase in the convergence of air at the edges of the RMGV, making the breeze arrive until one hour earlier, on 10/30 at 9am. With the presence of the city, the sea breeze was stagnant on the coast during the day
