WebThe AO Index (Arctic Oscillation Index) describes the difference of the air pressure between the Arctic and mid-latitudes. The stronger this difference, the stronger the West Wind Drift blows air masses from the North Atlantic to northern Europe and Siberia. If the index weakens and becomes negative, polar air flows far south, bringing cold ... WebThree climate oscillations affect New Zealand: Interdecadal Pacific Oscillation (IPO) lasts 20–30 years. El Niño–Southern Oscillation (ENSO) occurs every 2–7 years and lasts around a year. Southern Annular Mode can last for several weeks, but changes phases quickly and somewhat unpredictably. The southern oscillation index (SOI), which ...
