Resumo: | The easterly waves (DOL’s) are disorders of the trade winds, which, in northeastern Brazil, usually are associated with extreme precipitation events. This paper examines the evolutionary pattern of a DOL that hit the state of Pernambuco in June 2010, causing flooding and severe economic losses humans. The clipping chosen for analysis was the Una river basin, which had 11 affected municipalities. The analysis of the event based on the interpretation of images GOES-12 and TRMM. It was found that the analysis of GOES-12 images isolated not produce an effective, however, when combined with more information, come to a concise answer and extremely important for studies related to climate events. To evaluate the vulnerability to flooding of several municipal seats Una river basin, used a kernel density estimator based on the magnitude values of the drainage network. The results indicated that even naturally less vulnerable areas can be seriously affected by the amount precipitated. |

Este trabalho analisa o comportamento evolutivo de um DOL que atingiu o Estado de Pernambuco em junho de 2010, provocando inundações e grandes prejuízos humanos e econômicos. O recorte escolhido para análise foi a bacia hidrográfica do rio Una, que teve 11 municípios afetados. A análise do evento baseou-se na interpretação de imagens GOES-12 realçadas e TRMM. Constatou-se que a análise de imagens GOES-12 isoladas não produz uma resposta eficaz, no entanto, quando associada a mais informações, chega a uma resposta concisa e de extrema importância para os estudos relacionados a eventos climáticos. Para avaliação da vulnerabilidade à inundação das diversas sedes municipais da bacia do Una, utilizou-se um estimador de densidade Kernel baseado nos valores de magnitude da rede de drenagem. Os resultados indicaram que mesmo áreas naturalmente menos vulneráveis podem ser seriamente afetadas em função do montante precipitado.
