Abstract

This study concerns in to analyze extreme precipitation events and meteoric impact in the hydrographic basin of Igarapé Cereja, urban area of Bragança-PA, during the Amazonian winter of 2014. Therefore, the research was based on the SCU theory developed by Monteiro (1976). Meteorological data analyzed were collected Weather Station Conventional of Tracuateua (EMT) and Weather Station Automatic of Bragança (EMB) belonging to INMET, and it was installed a network of 07 rain gauges installed in the urban area of Bragança/PA that enabled development of variability maps precipitation during the rainy season 2014 in the area of Igarapé Cereja. With the aid of satellite images GOES 13 provided by INPE and Synoptic maps of the Navy of Brazil the active atmospheric systems were raised. With the results, it was observed that the ITCZ has increased participation in the occurrence of extreme events and urban impacts. There is a great variability of rainfall in the study area, up to 161 mm between the north-northeast sector (wettest) and the south-southwest sector (less rain).
