The climate and its variability are important factors in the configuration of geographic space, that is, in the composition of the environment, availability of natural resources and socioeconomic characteristics. However, even in the face of technological advances and advanced studies carried out on the dynamics of atmospheric systems, it is observed that society is still exposed to possible occurrences arising from climatic elements, such as those resulting from the variability of precipitation (both excessive and absent), causing the occurrence of: floods, flooding, and landslides, which cause great damage to the population. In the scope of geographic sciences, climatology has been concerned with analyzing how these episodes have repercussions in urbanized areas in order to understand the variability of its dynamics, as it can present trends, i.e., visualize future scenarios for a better understanding of the dynamics of climatic events. Thus, this research aimed to investigate the influence of the South Atlantic Convergence Zone - SACZ, in the intense rainfall that occurred - between 2000 and 2012, in the municipality of Ituiutaba, located in the southwestern portion of the state of Minas Gerais. The municipality is located in the Cerrado morphoclimatic domain, whose main climatic characteristic is the alternation of two well-defined seasons (dry season - april to september; rainy season - october to march), which has undergone a significant urbanization process and a large growth of its agricultural areas. The data used in the study come from the National Institute of Meteorology (INMET) and satellite images provided by the Prof.º Dr.º Victor da Assunção Borsato, emphasizing the consequences of its action in the main months that make up the rainy season: december, january and february, reinforcing reports gathered from news reports in the local press and the positioning of the municipal government.
