Positive values of SOI indicate La Niña conditions.
Text description of figure
A comparison of the mean sea-level anomaly and the Southern Oscillation Index (SOI) between 1973 and 2000 shows that sea level fluctuations of about plus or minus 0.12 metres closely follow variations in SOI, with higher than normal mean sea levels during La Niña episodes.
