Description :
The associations between mean annual stream flow records from 15 rivers draining the Argentine Andes, ranging from the Altiplano to Patagonia, and the Southern Oscillation Index (SOI) as established through simple lag cross-correlation, are examined. Climatological processes potentially responsible for the observed associations are reviewed, and possible lower frequency periods during the historic data record when these relationships may have changed, are identified. Then the findings are placed in a broader geographic and temporal context, and potential causes of longterm fluctuations are discussed.
