                         similar series for several other locations in Northeast Brazil. It 
                         is shown that the correlations are high for distances up to about 
                         600 km from Fortaleza. The Fortaleza series shows prominent 
                         periodicities at T=2.1, 10.1, 12.9, 25.1, and 61.0 years, all 
                         significant at a 3 s a priori level. Amongst these, T= 12.9 and 
                         25.1 years are significant at a 4a a priori level. A master Curve 
                         (for 1912-1978 only), obtained by averaging rainfall data for 93 
                         stations having good correlations with Fortaleza, shows very 
                         prominent periodicities at T= 5.6, 12.3 and 47.3 years, 
                         significant at a 3 s a priori level. T= 12.3 is significant at a 4 
                         s a priori level. Predictions from both the Fortaleza series 
                         (1849-1976)and the Master Curve (1912-1978)indicated droughts 
                         during 1979-1983. This prediction seems to have come true. In the 
                         future, droughts during 1992-1994 and 2002-2006 are indicated.",
