Abstract

Eigenvector analysis of 30 years of monthly and annual precipitation data from Argentina (63 stations) and Chile (24 stations) has revealed three dominant patterns of year-to-year variability which together account for more than 40% of the total variance. Significant correlations are found between precipitation variations and fluctuations in each of four indices of the general circulation: the Southern Oscillation| the pressure difference across the Antartic between Tasmania and the Falkland Islands region| the latitude of the high-pressure belt off the coast of Chile| and the pressure difference across the tropical Atlantic Ocean. (JPB).
