A investigacao das tendencias climaticas e das possiveis mudancas do comportamento climatico associado aos registros de alteracoes climaticas globais auxilia na reducao da vulnerabilidade as oscilacoes do regime de precipitacao. Este trabalho teve como objetivo avaliar as tendencias climaticas da precipitacao pluviometrica e dos indices de extremos climaticos no municipio de Garanhuns, Pernambuco - Brasil. Foram utilizados dados diarios de precipitacao no periodo de 1961 a 2014, fornecidos pelo Instituto Nacional de Meteorologia-INMET. Para atingir o objetivo proposto foi utilizado o software Climap para analisar a tendencia da precipitacao e dos indices de extremos climaticos, assim como o teste sequencial de Mann-Kendall para verificar o ano aproximado em que as tendencias tiveram inicio. Os resultados indicaram que nao houve tendencias nas series dos totais anuais e nos indices de extremos de precipitacao. Porem, constatou-se uma possivel alteracao na serie de precipitacao total anual a partir de 2003, e a predominância da alta variabilidade anual da precipitacao pluviometrica na regiao.

This study aimed to assess climate trends of rainfall and climatic extremes indices in the city of Garanhuns , Pernambuco – Brazil. Daily rainfall data were used from 1961 to 2014 , provided by the National Institute of Meteorology - INMET . To achieve purpose we used the CLIMAP software to analyze the trend in rainfall and indices of extremes climatic, as well as the sequential Mann- Kendall to check the trend. The results indicated that there was no trend in the series of indexes of extremes climatic and the total annual precipitation. However , there was a possible change in annual rainfall from 2003 , and high annual variability of rainfall in the region. Keywords : climate, rainfall, Climap.
