                         6 and 12 months, using the Standardized Precipitation Index (SPI) 
                         in different Amazon locations that have distinct climatic 
                         characteristics: Manaus, Bel{\'e}m and Iauaret{\^e}. The long 
                         term trends for the SPI16 are also presented, once they are 
                         adequate for analyzing the variability between the dry and rainy 
                         seasons. A higher frequency of extreme and very extreme rainy 
                         events was observed when compared to the dry events, in all three 
                         locations and all time scales. This characteristic was enhanced 
                         for Iauaret{\^e}, place that had the largest annual total. 
                         Significant long term trends were not found for the SPI16 and only 
                         Iauaret{\^e} shows long sequences of SPI16 varying above and 
                         below the normal.",
