To the point where you could almost say that when this part of the Pacific catches a cold, the whole world has a fever.
That's correct.
But in an El Nino year, the sea surface temperatures, the ocean temperatures in that part of the Pacific, rather than gliding down, stays high and sometimes even keeps increasing.
And if the gap between the temperatures in a given year and the usual temperatures is 0.5 Celsius, a pretty small threshold, that is an El Nino.
If the gap between the water temperatures is two Celsius greater than usual, then you have a super El Nino.
And Michael, this year we could be heading even for a three degree gap, which is beyond what we've ever seen before.
Yeah.
The terminology doesn't exist for it.
Okay, so let's go back to this rectangle.
Imagine in a normal year that the winds above these waters are blowing the warmth away from South America towards Asia.
Okay?
So these waters are staying relatively cool.
They're cooler than the waters in Asia.
And there's cold water that's coming up to replace the water that was getting blown away.
And so you have a nice cold ecosystem.
This is of course important to fish and all this other stuff.
In an El Nino year, that pattern changes quite a bit.
And the winds that normally take that warm water away either slow down or reverse.
And that is one key element in this feedback loop, in which the warm water is no longer displaced.
Instead, it starts to build and generate on you could say, quote unquote, the wrong side of the Pacific.
