Utilizando parâmetros meteorológicos na investigação da atuação dos mecanismos atmosféricos moduladores da precipitação no período de inverno sobre o Nordeste Brasileiro (NEB), e caracterizar qual fenômeno modulou aprecipitação intensa ocorrida entre os dias 17/06/2010 e 19/06/2010 por meio de dados de reanálise do NCEP/NCAR, dados de precipitação da Plataforma de Coleta de Dados (PCD’s), do Instituto Nacional deMeteorologia (INMET) e imagens de satélite do Centro de Previsão de Tempo e Estudos Climáticos do Instituto Nacional de Pesquisas Espaciais (CPTEC/INPE). Observou-se através dos campos gerados pelo software Grads, as características atmosféricas propícias ao favorecimento da convecção sobre o NEB no mês de junho e em específico nos dias 17, 18 e 19 de junho onde foram registrados os valores mais elevados de precipitação, foi realizado o diagnóstico dos sistemas sinóticos atuantes nos três dias, em estudo, caracterizando as perturbações vindas de leste como o sistema responsável pela formação do complexo convectivo que atuou sobre o estado de Pernambuco. AbstractThe use of meteorological parameters is important to investigate its function on the atmospheric modulators mechanisms of precipitation during the winter over the Northeast Brazil (NEB). This study aimed to characterize the phenomena which modulates the intense precipitation occurred between the days 17 to 19/06/2010 through the reanalysis data of NCEP / NCAR precipitation data of the Platform for Data Collection (PCDs), the National Institutes of Meteorology (INMET) and satellite images of the Center for Weather Forecasting and Climate Studies, National Institute for Space Research (CPTEC / INPE). It was observed, through the fields generated by the software Grads, that the atmospheric characteristics that permit the convection over the NEB in June and, in particular, on days 17, 18 and 19 June when was we registered the highest values of precipitation, when the diagnosis of synoptic systems operating in three days was performed; itcharacterized the disturbances coming from the east, as the system responsible for the formation of convective complex that occurred on the State of Pernambuco.
