A relação entre a variabilidade climática e o cotidiano da população constitui-se no enfoque da climatologia, evidenciando diferentes impactos socioambientais no espaço. As chuvas intensas deflagram eventos no Brasil principalmente no período da primavera-verão que causam diversos transtornos a vida social, além disso, potencializam os riscos na população mais vulnerável. Na Amazônia Brasileiras, esses eventos repercutem muitas vezes em episódios com quedas de árvores, acometimento de doenças relaciona à água, perdas na agricultura, deslizamento de terras e a morte de pessoas por naufrágio das embarcações. O objetivo deste estudo foi analisar os eventos de precipitação pluvial intensa e os riscos para a população da cidade de Tefé localizada na região do Médio Solimões no estado do Amazonas/Brasil. Para isso, foram utilizados dados de precipitação pluvial da estação meteorológica do Instituto Nacional de Meteorologia (INMET) em Tefé do período de 1970-2012. Os dados foram tratados com técnicas estatísticas descritivas bem como por meio da técnica do percentil para análise dos episódios de precipitação diária intensa. Adicionalmente, utilizou-se de notícias de jornal da cidade de Tefé para identificação dos riscos. Os resultados demonstraram que os eventos de precipitação intensa têm aumentado na última década e esses eventos potencializam a ocorrência de impactos a população mais vulnerável, como deslizamento de terra e destruição de residências construídas em áreas de risco. Conclui-se que o estudo pode servir como subsídio a formulação de políticas públicas associadas ao planejamento urbano para mitigação dos riscos à população.

The relationship between climate variability and the population's daily life constitutes the climatology of focus, showing different environmental impacts in space. Heavy rains trigger events in Brazil mainly in the spring-summer period that cause various disorders social life also leverage risks in the most vulnerable population. In the Brazilian Amazon, these events reverberate often in episodes with falls of trees, diseases of involvement relates to water losses in agriculture , landslides and killing of people by sinking vessels. The objective of this study was to analyze intense rainfall events and risks the population in Tefé located in the Middle Solimões region in the state of Amazonas / Brazil. For it, were used rainfall data from the Meteorological National Institute of Meteorology Station (INMET) in Tefé of the period 1970-2012. Data were treated with techniques descriptive statistics as well as percentile, technical middle, of the analysis of episodes of intense daily precipitation. Additionally, we used the newspaper report the city of Tefé to identification of risks. The results showed that intense precipitation events has increased in the last decade and these events potentiate one impacts occurred one population more vulnerable, like landslide and destruction of homes built in risk areas. We conclude that the study can serve as the subsidy of associated public policy formulation to urban planning for mitigation of hazards population.
