I'm sure it's due to some dumb USA law but the entirety of the NYC parks department fleet is nowadays F250s. We have some electric John Deere Gators that I have to fight to get assigned, but all the rest is just huge honking trucks that can't even drive through the paths in the parks and I'm supposed to haul mulch and garbage through tiny paths filled with people in a huge battle truck.

We have one smaller Ford ranger at our district that the supervisors use to go around and do surveys. That truck makes sense, but lol, it's due to be sent back and never return.

For every moderately well understood phenomenon, like El Niño, there are a dozen unknown ones. Nowhere is safe. Certainly not the places our limited predictions say will be.

in other words, I hope you enjoy the Minnesota atmospheric microplastic geyser of 2039 or whatever

(except Duluth, it’s climate proof)

Great post thanks man. Lots to think about.

Also something to note is that the jet stream is weird even without this going on thanks to the weakening polar vortex, and el nino is going to make it even weirder. I wonder if models can even keep up with how differently the atmosphere is starting to act

This is a complicated line of thought (jet dynamics are extremely dynamic and complex) but El Nino strengthens the jet and displaces it south. It is by definition not associated with the meandering jet stream that has presented often recently.

The general predisposition is shown here:



And I should say again that we are focusing on the north pacific and its attendant flows and not a worldwide scenario. The jet is a projection, at least in part, of the effects of the atmospheric bridging between equatorial heat and its transportation into the jet flow.

Or to put it more easily, the jet is typically pretty localized, and responds to heat south of it on the equatorial band. Therefore the effects of El Nino, while having downstream effects, are more locally effective directly and adjacently north of it. Which is to say, it affects us the most.

Though it also depends on where the El Nino is centralized. There are numerous +ENSO modes. El Nino Modokai, or centrally displaced El Nino, all the way to a strong EP, or east pacific El Nino. The latter of which is the canonical El Nino and the one that has by far the biggest and most forecastable effects on the USA and adjacent nations.

Ever since the 97-98 El Nino switched us into a new climatology, subsequent El Ninos have been rather uninspired, and often not canonically presented in the far EPAC, which has meant that El Ninos have even been rather detrimental to rainfall in the last 30 years.

If an El Nino is not east pacific based that is normally due to a weakness in the system dynamics- the kelvin waves that push warm water eastward don't have the oomph and staying power to stay lodged against the far EPAC so you get a more centrally displaced event, which in turn effects the atmospheric bridge, which then establishes cell dynamics where the USA has to deal with a falling/non-convective branch. That's how weaker El Ninos and/or centrally positioned El Ninos can show effects far different from a canonical event.

It's important to understand that broadly speaking, El Nino is an attempt to balance the system which is made unbalanced by the trade winds caused by a rotating earth. The equatorial waters are warm on the surface, and then the completely normal west-bound trade winds pile up all of that water in the West equatorial pacific.

This makes the Pacific Ocean literally unbalanced:



Get what I'm saying here? The warm West Pacific waters slosh over to the Eastern Pacific with often great momentum, because the water is literally evening out, which imparts velocity to the packets (kelvin waves).

You can almost think about this like the far west pacific is normally experiencing enhanced El Nino-like effects due to the captive water there. When an El Nino event happens, that water shifts to the east, which then establishes the uplifting/convective branch of the circulation off the EPAC and therefore pumps the jet stream to the north of it due to the atmospheric bridging.

And that's, broadly speaking, the system: water is built up in the west pacific. Once that water gets too unbalanced, it's like a hot water kettle, I guess; at some point the system attempts to re-equalize which throws quickly-traveling packets of warm water eastward, which are called kelvin waves.

Idk if this is even worth describing due to how technical it is. I hope this is of help.



The TAO system is a bunch of buoys on the equatorial pacific that track these kelvin waves and here is where we are now- you can see kelvin waves traveling east and piling up:



It's quite scary, this is very strong for this time of year, and another WWB (western wind burst) is initializing which will push even more eastward, and it's looking extremely robust, look at those westerly winds! Very unusual!

Note: The box drawn on the equator represents the zone in which westerly winds will generate kelvin waves- they must be almost dead on the equator.

These winds are about to generate a typhoon as well!





Which then causes the kelvin waves you are seeing in action here:



^ This image above is easier than it looks. It just shows the equator; warm waters traveling to the far east of the image, which is off ecuador and presents us with our far east-pacific "real deal" El Nino system.

Once these waters establish and the ocean/atmospheric systems are coupled, you then get a steady flow of water to Ecuador/Galapagos until El Nino fizzles sometime in winter. Though El Nino events can last more than one year.

Random note: a lot of people say that El Nino is the opposite of La Nina, even nominally learned people sometimes claim this, but it couldn't be further from the truth. El Nino represents an entirely different climatological regime; La Nina is just the further strengthening of the trade dynamics that already exist in the pacific.

I was watching the local news in Portland and saw this lmao:



I moved here because I love temperate rainforests and their mild weather. Now it gets hot as poo poo in the Spring and Summer, trees have mass die offs, my garden keeps getting killed, we have a smoke season, and it stops raining for a month at at time. The day it hit 115F hosed up a lot of people here.

“I don’t want to be, you know, doomsaying, but I mean, we are currently depending for almost all of our fruits and vegetables on one small geographic region, which is currently in a drought. And that drought is expected by all estimations to probably be worse over the next 10 years,” says Evan Fraser, director of the Arrell Food Institute and professor of geography at the University of Guelph.

“If California can’t produce and export with the same level of stability and predictability and costs that it’s had over the last 20 years, the implication of that is going to be higher prices and periods of disruption.”
