The objective is to understand intra-urban pluviometric variability and its relationship with the main atmospheric systems active in the Amazon region. The methodology is based on the integration of data from meteorological stations, manual rain gauges, and remote sensing, covering discontinuous periods between 2017 and 2025. Data were organized and analyzed using Excel spreadsheets and Geographic Information Systems (GIS) environments, specifically QGIS 3.40 software. The application of Inverse Distance Weighting (IDW) interpolation and zonal statistics tools enabled the spatialization of precipitation, the creation of thematic maps, and complementary statistical analyses. The results highlight the occurrence of the Af climate type according to the Köppen-Geiger classification; an irregular distribution of rainfall across space and time, with positive and negative anomalies in several years—particularly during the less rainy period, locally known as the Amazonian "summer"; and differences in total and average precipitation among the neighborhoods of the Urban Macrozone, with the most humid areas located in the southwest, all in proximity to Belém. Despite the higher concentration of data during the "summer," it was observed that this variability is primarily associated with macro-scale atmospheric systems, such as the Intertropical Convergence Zone (ITCZ) and Sea Surface Temperature (SST) anomalies in the Atlantic (North and South Dipole) and Pacific (El Niño and La Niña) oceans. Regarding precipitation correlations with nearby locations, very strong and strong values were found for Belém, Outeiro, and Santa Izabel do Pará, indicating a more homogeneous climatic zone in this part of the Metropolitan Region of Belém (RMB). The study concludes that, although temporally limited and requiring further research, it contributes to the knowledge of local atmospheric and climatic dynamics in the Urban Macrozone of Ananindeua. It highlights real scenarios of hydrometeorological risks, such as severe droughts, flash floods, and flooding, while emphasizing the importance of geotechnologies for climatic analysis and urban planning focused on risk and disaster management.Acesso AbertoPrecipitaçãoVariabilidade climáticaGeoprocessamentoPrecipitationClimate variabilityGeoprocessingCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::METEOROLOGIA::CLIMATOLOGIATrabalho de Curso - Graduação - Monografia
