                         vital importance in the knowledge of the caused climatic impacts 
                         in such a way in the regional scale as in the global one. The 
                         region of the estuary of the river Amazon has a climatic behavior 
                         of different rains of the too much areas of the Amazon region. The 
                         main meteorological system that acts on this e region the 
                         Inter-tropical Convergence Zone (ITCZ). The rainy period in this 
                         region goes of December the April. This work has the intention to 
                         show a possible change in the variability of rains, using given of 
                         stations located in the band of 51øW 48øW and 02øS 0ø. These data 
                         had been gotten through the National Agency of Energy from Brazil 
                         (ANEEL). The variability of rains in the February months the May 
                         (rainier period)since of 1979 up to 2000, sample that mainly had a 
                         bigger variability of the anomalies, in the period of 1979 up to 
                         1988, from 1989 this variability diminished, being the year of 
                         1983 what it presented the biggest rain anomaly, this due to 
                         presence of the phenomenon El Ni¤o that was acting. This region 
                         has a possible influence of the El Ni¤o. In this period of study, 
                         it was verified that extreme rains (superior 60 mm)will diminish 
                         in the reason of y = -0,1228x + 5,6491. In the years of the 
                         1982-83 and 1991-92 occurrence of extreme events she was very low, 
                         in the 1991-92 case was not registered superior rain occurrence 60 
                         mm. The number of days without rains, also had a reduction in the 
                         reason of y = -0,8793x. 103,81. In the years of 1979-80, the 
                         1980-81 and 1982-83 number of days without rains had been bigger, 
                         this associate the presence of the El Ni¤o, mainly in the years of 
                         1979-80 and 1982-83.",
