                         discussed. First, rainy and dry seasons for several stations of 
                         Brazil are determined using the data of 21 years(1958-1978). The 
                         progressive movement of the Intertropical Convergence Zone seems 
                         to be associated with the progresive variation of rainfall seasons 
                         in the equatorial eastern Brazil. The annual migration of deep 
                         tropical convection from Central and southern Portion of the 
                         Amazon basic in austral summer to the northwestern sector of South 
                         America in austral winter seems to be responsible for the annual 
                         cycle of rainfall in the Amazon basin. The conncection between the 
                         interannual variation of rainfall over Brazil and the Southern 
                         Oscillation is also discussed. The correlation coefficient between 
                         the Southern Oscillation index and the rainfall is generally small 
                         over most of Brazil except over Rio Grande do Sul. The correlation 
                         between the spring rainfall of Rio Grande do Sul and and the 
                         Southern Oscillation index of the same or of the previous season 
                         is significantly high and shows prospects for seasonal rainfall
