                         1920s, is analyzed to verify if there are long-term trends. 
                         Annual, rainy season and dry season rainfalls are individually 
                         analyzed. In general, the stations in the southeastern sector of 
                         the Amazon basin showed downward trend while the stations in 
                         northwestern Amazon basin showed upward trend in the past 80 
                         years. Alarmingly large negative trends of more than 100 mm/season 
                         in 80 years are observed at Itacoatiara and Manicore in the 
                         southeastern sector in the rainy season rainfall. An important 
                         question arises: Can we attribute these negative trends to 
                         deforestation in the Amazon rim region? Chuva observada em oito

                         convencionais desde meados dos anos 20 {\'e} analisada para 
                         verificar tend{\^e}ncias de longo prazo. Chuva anual, chuva da 
                         esta{\c{c}}{\~a}o chuvosa e da esta{\c{c}}{\~a}o seca foram 
                         analisadas separadamente. Em geral, as esta{\c{c}}{\~o}es no 
                         setor sudeste mostraram tend{\^e}ncias negativas e 
                         esta{\c{c}}{\~o}es no setor noroeste tend{\^e}ncias positivas 
                         nos 80 anos passados. Tend{\^e}ncias negativas alarmantes com 
                         valores de mais de 100 mm/esta{\c{c}}{\~a}o em 80 anos foram 
                         observadas na chuva da esta{\c{c}}{\~a}o chuvosa no setor 
                         sudeste da bacia (Itacoatiara e Manicore). Uma pergunta importante 
                         surge: Podemos atribuir estas tend{\^e}ncias a 
                         destrui{\c{c}}{\~a}o da vegeta{\c{c}}{\~a}o no arco de
