| Sumario: | http://dx.doi.org/10.5902/2179460X12875In this work was analyzed a flood case registered in Pelotas-RS region in January 2009. Different data sources were used: rainfall hourly data from Pelotas Agrometeorological surface station and rainfall daily data from 16 meteorological surface stations of RS, to verify the rainfall registered in Pelotas and RS during flood occurrence; infra-red (channel 4) satellite imagery from GOES 10, to analyze the evolution of meteorological system that generated the flood; radar reflectivity data from Canguçu meteorological radar to analyze the convective activity related to the flood case and data from NCEP-CFSR Reanalysis (National Centers for Environmental Prediction – Climate Forecast System Reanalysis), to analyze the large-scale environment associated with flood case. The results showed that atmospheric conditions observed in the region were extremely favorable to formation and development of the extratropical cyclone that formed from 01/28/09 and favored the flood case occurrence in Pelotas on 01/29/09 |
