Replace jet stream with El Niño/la Niño, and you have your layman title. Of course, this is a spectacular year since its been a while since there have been a La niña sandwiched between 2 el Niño events, contiguously. Not sure when that happened last.

"Jet Stream" is more familiar to those in Europe I'd imagine.

  Yep. We hear about the jet stream regularly in the UK. I see the El Niño stuff lots online but no idea what it is or if it impacts UK/Europe.

    El Nino/La Nina refer to Pacific Ocean current patterns, and thus matter especially to people on the Pacific coasts. You hear about it because this includes people in California and Washington US states (among others), which are overrepresented on this board, as well as all of China, Japan, South East Asia etc. However, they can produce global effects, as the pacific ocean is really big. In the UK, you probably hear about the Gulf Stream a lot.

  I grew up hearing about how the jet stream was going to affect the weather, and I lived in Indiana (US) - and I lived there until my mid-30s.

  Thank youfor the info. I was under the impression that this chain of events was rarer that what it seems to be. 2016 in particular is a recent and next-to-last el Niño event, and its one that i would have expected to remember / know more about. But clearly i did not

El Nino/La Nina are completely different phenomena from jet streams; the former are to do with sea water, the latter are high velocity streams of air in the high atmosphere.
- IG_Semmelweiss 3y ago
  They are different manifestations of the same weather event. Sea water temp changes the air temp above it. A big enough change will clash with existing air above.it, and the interaction of those 2 causes jet streams. I'm open minded as to believing those are mutually exclusive but reading doesnt suggest that at all

El Niño is more a pacific thing, the Jet Stream is an Atlantic thing I believe. We hear more about the Jet Stream in Europe. I wander if this is related to the abnormally warm North Atlantic sea surface temperatures.

  Fwiw, The jet stream circumnavigates the globe, there are multiple as well https://www.noaa.gov/jetstream/global/jet-stream https://www.noaa.gov/jetstream/global/jet-stream

    Thank you, that’s a clear explanation of the cause and 3D shape of jet streams.
- nwallin 3y ago
  The Jet Stream is a global wind current in the upper atmosphere that circumnavigates the world. It's equally relevant to all countries in temperate regions. El Niño is a warming of the water in the North Pacific that sometimes happens and sometimes isn't. It has an outsized impact on the weather in the Western US. The Gulf Stream is a current in the North Atlantic that brings warm water from the Gulf of Mexico to the North Atlantic, where it has an outsized impact on the climate in Europe.

  While El Niño is related to Pacific Ocean temperatures it has global implications.

Also spectacular because we might have had the hottest day globally in 100,000+ years.

  It's a record that's unlikely to last another 100,000 years.
