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.
20世纪90年代初热带太平洋地区出现意外且持续时间较长的温暖状况，这可归因于一种年代际气候波动，这种波动涉及赤道温跃层性质的变化，而这种变化是由来自高纬度地区的异常温度水体涌入造成的。这种涌入影响赤道海表温度，进而影响热带和温带风，而热带和温带风又反过来影响这种涌入。一个简单模型表明，这些过程会引发持续的年代际振荡。
