We see a strong variability from year to year. On a scale of several decades, the period 1940-1980 is characterized by particularly high flow rates. The early 20th century was rather dry. A coupling to the 60-year-old ocean cycle offers itself. The Pacific is far away, but the wet Zambezi phase fits quite well into the negative PDO:
