El Niño–Southern Oscillation - Wikipedia
El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variations in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some semblance of cycles. The occurrence of ENSO is not predictable.

2017年2月14日 · El Niño is the largest natural disruption to the Earth system, with direct impacts across most of the Pacific Ocean. Indirect impacts reverberate around the globe in patterns that scientists refer to as teleconnections.
What we talk about when we talk about the jet stream and El Niño
2023年9月29日 · We expect to see an extended and equatorward shifted jet stream, as is typical for El Nino winters. The exact details though will determine the impacts we see and those are probably not forecastable months in advance.
