                         chuva variando entre 3% a 6% no per{\'{\i}}odo em estudo. Por 
                         outro lado, observou-se nos eventos extremos de seca uma

                         In recent decades, the Earth's climate has been showing changes in 
                         their behavior by increasing the frequency of extreme climatic 
                         events, most likely associated to global climate change, whose 
                         theme became popular and point of discussion the general public. 
                         In this context, this study presents an analysis of the frequency 
                         of the extreme dry and rainy events in the Amazon based on monthly 
                         rainfall series of four databases GPCP (Global Precipitation 
                         Climatology Project), GPCC (Global Precipitation Climatology 
                         Center), CPC (Climate Prediction Center) e Era-Interim in the 
                         period 1979-2014. The extreme dry and rainy events were 
                         characterized by Standard Precipitation Index (SPI) being applied 
                         to different time scales (3, 6 and 12 months). The results showed 
                         expressive differences in the frequency of extreme dry and rainy 
                         events in the four databases. However, it was noted in the three 
                         scales of SPI, in all seasons and in the four databases that 
                         Amazon presented frequencies of extreme rainy events ranging from 
                         3% to 6% in the study period. Moreover, it was observed in extreme 
                         dry events changes by more than 6% of frequencies.",
