The meaning of SOUTHERN OSCILLATION is a periodic seesaw fluctuation in sea-level atmospheric pressures over the southern Pacific and Indian oceans that is believed to be linked to El Niño and La Niña events.

The El Niño/Southern Oscillation is characterized by irregular warm (El Niño) and cold (La Niña) events in the tropical Pacific Ocean, which have substantial global environmental and socioeconomic impacts. These events are generally attributed to the instability of basin-scale air–sea intera...
It is commonly measured using the southern oscillation index (SOI) derived from sea level pressure data at specific locations, and it is known for its impact on rainfall patterns and climate variability in regions like Australia. AI generated definition based on: Earth-Science Reviews, 2018...
The Southern Oscillation is an important mode of operation of the atmosphere. Several indices of the Southern Oscillation have been recognized, but for many purposes an index that gives a continuous, homogeneous time series is required. Phase differences between various areas complicate the definition ...
