Abstract:

The spatial and temporal distributions of rainfall for the equatorial latitudes on the Pacific coast of South America are described by graphical and statistical means. A relationship is established between the rainfall distributions and the offshore oceanic current regimes which is highly linear in nature. Anomalous rainfall years are then analyzed to determine a possible correlation with movements of the subtropical oceanic high pressure systems. The controversial question of the periodicity of rainfall anomalies is tested by harmonic analysis techniques. Author
