Question
Southern Oscillation Index is the seesaw relationship in sea level pressure between
The correct answer is
eastern tropical Pacific and the tropical Indian ocean
The Southern Oscillation Index (SOI) is a key indicator used in climatology. It measures the fluctuations in sea level atmospheric pressure.
Southern Oscillation Index Regions
The SOI specifically quantifies the seesaw relationship, or pressure difference, between two distinct oceanic regions:
- The eastern tropical Pacific Ocean.
- The tropical Indian Ocean.
The variation in pressure between these two areas is fundamental to understanding major climate phenomena like the El Niño-Southern Oscillation (ENSO).
