Abstract: Environmental impacts affect the environmental quality in a specific environment where they occur, causing environmental and socio-economic damages in the area directly affected by them or within their sphere of influence. Despite being an important factor in the planet's hydrological cycle, rainfall can lead to various adversities in a particular environment, especially when it occurs in large quantities. Intense rainfall can cause various disruptions in large urban centers, primarily due to the lack of an effective urban drainage system, affecting primarily low-income individuals who are more vulnerable. Linked to rainfall during the rainy season in much of Brazil, the South Atlantic Convergence Zone (SACZ) is a band of cloudiness and rainfall with significant spatial and temporal variability, influenced by various factors such as upper-level divergence and moisture transport to the regions it covers. It is also responsible for altering normal atmospheric conditions. Therefore, the objective of this study was to identify the SACZ, assess the factors influencing it, and its impact on the Earth's atmosphere, examining the reported impacts during the event from January 29 to February 8, 2018. To do this, surface synoptic charts were obtained to evaluate the extent and temporality of the SACZ, along with 250 hPa data, observed rainfall, outgoing longwave radiation, and enhanced cloud-top temperature satellite images from GOES-16.
