1990年代初热带太平洋地区温暖条件的意外和长期持续，可归因于年代际气候波动，其中涉及来自高纬度的具有异常温度的水的涌入引起的赤道温跃层性质的变化，这种涌入影响赤道海面温度，从而影响热带和温带风，进而影响涌入。
The unexpected and prolonged persistence of warm conditions over the tropical Pacific during the early 1990s can be attributed to an interdecadal climate fluctuation that involves changes in the properties of the equatorial thermocline arising as a result of an influx of water with anomalous temperatures from higher latitudes, The influx affects equatorial sea-surface temperatures and hence the tropical and extratropical winds that in turn affect the influx, A simple model demonstrates that these processes can give rise to continual interdecadal oscillations.
