. The coastline of Bahia State, Brazil, in the eastern sector of the northeastern region of Brazil, has a total of 20 beaches, 14 of which are located on theopen sea (Atlantic Ocean), while the others are sheltered in the Todos os Santos Bay. Many of these beaches have been or are currently being affected by episodes ofsevere coastal erosion which are intrinsically related to both anthropogenic and natural processes. This study aimed to use statistical analyses of information and data,such as photos, texts from local newspapers, synoptic maps and reanalysis data from the National Centers for Environmental Prediction to identify severe erosion eventsrelated to meteorological tides on the Salvador coastline during the period from 1965 to 2006. The results show that most erosion events appear to be associated withthe occurrence of meteorological tides and have great destructive potential. We found that the combination of i) the occurrence of spring tides with ii) the arrival of coldfronts and/or coupling of a high pressure system with a trough in the lower levels of the atmosphere and iii) winds predominately from S and SE, that through Ekmantransport, promotes pilling up of water against the coast, favours the increase of the water level and wave height and range along the coast. Keywords: cold fronts, Ekman transport, spring-tides, severe coastal erosion. RESUMO . O litoral de Salvador, no Estado da Bahia, possui um total de 20 praias, das quais 14 estao localizadas em regiao de mar aberto, no setor leste do Nordeste brasileiro, banhadas pelo oceano Atlântico, enquanto que as demais se encontram abrigadas na Baia de Todos os Santos. Dentre estas praias, muitas foram ou estao sendo acometidas por episodios de erosao costeira severa, que estao intrinsecamente relacionados a acao tanto de origem antropica quanto natural. O presente estudo visou, atraves de analises e estatisticas de informacoes e dados como fotos, textos de jornais locais e cartas sinoticas e reanalises do National Centers for Environmental Prediction dos EUA, identificar os eventos de erosao severa relacionados a ocorrencia de mares meteorologicas na orla de Salvador, no periodo de 1965 a 2006. Os resultados mostram que a maior parte dos eventos erosivos parece estar associada a ocorrencia de mares meteorologicas, com grande potencial destrutivo. Este estudo permitiu constatar que a combinacao: i) da ocorrencia de mares de sizigia, com ii) a chegada de frentes frias e/ou o acoplamento de uma alta pressao a umcavado, nos baixos niveis da atmosfera, e iii) a predominância de ventos de S e SE, que atraves do transporte de Ekman, promovem empilhamento de agua contra acosta, cria uma conjuncao que favorece a sobre-elevacao da altura e do alcance das ondas ao longo da costa. Palavras-chave: frentes frias, transporte de Ekman, mare de sizigia, erosao costeira severa.
