 Interdecadal Pacific oscillation

The Interdecadal Pacific Oscillation (IPO) is a long-term climate variability pattern in the Pacific Ocean that can influence climatic conditions across the globe. It is characterized by fluctuations in sea surface temperatures (SST) and atmospheric pressure across the Pacific Ocean on interdecadal timescales, typically spanning several decades. The IPO can switch between phases, similar to the El Niño Southern Oscillation (ENSO), but with much longer cycles.
