Abstract
This study aimed to assist the planning of actions, preventive and mitigating measures, the natural disasters for civil protection in the Duque de Caxias city, and used the Classification and Coding Brazilian Disaster (COBRADE) for identification of 35 natural disasters between the years from 1996 to 2015, where 74% of these events occurred between the months of November and February, 20% occurred in 2009. To diagnose the weather systems we used the Bulletin of Climate Studies of Weather Center – CPTEC, where 57% of disasters were associated with the South Atlantic Convergence Zone (SACZ), 29% the passage of cold fronts and 14% to local instability areas. The aim of assisting the preparation of sirens drive protocols, we analyzed the spatial distribution of rainfall occurred in 116 rain gauges. The results show that for SACZ event, the higher frequency range of daily rain accumulated ranged between 10 and 50 mm on the last 24 h, and between 60 and 110 mm on the day of disaster. For cold fronts, retained varied between 40 and 110 mm, and to areas of instability between 30 and 95 mm.
