O foco deste trabalho sao as rajadas de vento registradas no Aeroporto Internacional de Salvador no periodo 2003-2011. Variaveis meteorologicas observadas a superficie na area do aeroporto, imagens de satelites meteorologicos e dados em pontos de grade foram utilizados para analisar a variabilidade interanual, sazonal e horaria das rajadas, e diagnosticar as condicoes sinoticas de um caso selecionado. Um percentual de 51% do numero total de rajadas de vento foi registrado em 2003 e 2007 (em conjunto), com valores muito proximos. O mes de maio teve o maior percentual de registros de rajadas (22%), e as direcoes do setor sul da rosa dos ventos foram as mais frequentes (51%). No caso selecionado (10-11 de maio de 2007) houve cinco registros, no periodo da noite, com a direcao do vento variando entre 170 e 200 graus. A rajada mais forte, com 190 graus e 69 km/h, ocorreu as 01 UTC do dia 11. Nuvens de conveccao profunda (cumulos congestos) foram observadas na area do aeroporto. Esse caso foi associado a passagem de um sistema frontal em Salvador, evidenciada pela variacao diaria de elementos atmosfericos observados a superficie na estacao meteorologica do aeroporto. Segundo a Coordenadoria de Defesa Civil de Salvador (CODESAL), as fortes variacoes do vento causaram desabamento e destelhamento de imoveis registrados no dia 11.   A B S T R A C T This work focuses on wind gusts observed at the Salvador International Airport during the period 2003-2011. Surface meteorological variables observed at the airport, meteorological satellite images and gridpoint data were used to analyze the interannual, seasonal and hourly variability of the wind gusts and to diagnose the synoptic conditions of one selected case. A fifty two percent of the total number of wind gusts was found in 2003 and 2007 (altogether), with very close values. May had the highest percentage of wind gust reports (22%), while wind directions in the southern sector of the wind rose were more frequent (51%). The selected case (10-11 May 2007) had 5 gusts, at night, with wind direction varying from 190 to 200 degrees. The strongest wind gust, with 190 degrees and 69 km/h, occurred at 01 UTC on the 11th. Deep cumulus clouds (cumulus congestus) were observed within the airport area. This case was associated with a frontal passage in Salvador, as shown by the daily variability of the atmospheric elements observed at the airport surface meteorological station. The Civil Defense of Salvador (CODESAL) registered collapsed and unroofed houses on the 11th.  Keywords: surface wind, extreme event, frontal system, Bahia, Northeast Brazil
