Resumo

The objective of this research was to analyse the temporaland spacial variabilities of precipitation during two thirty-dayperiods of the rainy season in the Buritis and Estoril districts, bothof them located in the West region of Belo Horizonte. Theinfluence of topography, altitude and morphology in the increase of urban atmospheric instability and the daily rainfall totals were evaluated. In order to analyse the data and selection of the sample sites, a digital model of elevation and a map of the use of the ground were prepared. The precipitation reading was standardized for 12h GMT, corresponding to the accumulated total of 24h. Theidentification and interpretation of the types of weather werepossible by using graphics of rhythmic analysis, sinotical map and satellite images. The experiment indicated high correlationbetween irregular topography and the amount of precipitated rain, proving the effect of the morphology on the increase of the atmospheric instability.
