Those easterlies are a little above normal anomaly wise. I posted pure wind direction and speed. Usually when there is a WWB there's usually countering easterlies on the other end as they tighten up against each other. But the WWB is pushing WPAC waters further east in time.

Ntxw is this WWB the real deal?

If so, I'm thinking more than just 1C being solidified, and maybe 1.5C averages throughout the summer.

And two Typhoons especially 07W will help things with the westerlies.

Ah, thanks. I didn't notice it said wind totals, not anomalies. Since that's the case, this WWB looks pretty impressive. :D

It is the real deal. A couple more 1C+ readings and we've already seen a month's worth of that. If the WWB continues, an OKW will more than likely intensify the warm pool in the central Pacific below. That will keep it going through summer, my bet is on our way to a strong Nino at this point. There is very good correlation between May WWB's and the more intense Nino's that become stronger. The atmosphere and ocean are coupled.

:uarrow: Wow, that's insane.

There's been a bit of chatter on twitter between Blake and Ventrice the past few weeks, with many comparing this event to 1997.

It looks like the weekly update on Monday May 11 by CPC will have a reading below +1.0C.

The readings last week were about 1.0-1.2C in average, so that is what we will see

I saw the CFS forecast for WWB. I'm interested in what happens with the coming WWB as it is expected to be stronger than early May. So far this spring, as we approach them the GFS has underforecasted these WWB.

Some are saying this el nino could be as strong as 97. I just bought my Honda shadow bike back then. Kept the bike under an open garage in N. Miami Beach. What I call the groundhog day storm. Picked my 600 lb bike and flipped it over. Bent my handle bars. I had a cover over it which I think acted as a parachute. Winds were 60-70 mph that night. That month also produced an unprecedented number of tornadoes in central florida. Many deaths and distruction in a RV park. I would guess was attributed to 97-98 El Nino. :eek:

Wow -44.18 soi. That's a sign :roll:

Is it possible we've seen the peak of this El Nino as looking at the sub surface near the date line it seems as though the +2+ anomalies are shrinking some but I do think the 1-2-3 regions will warm some as that area with the subsurface is rediculously warm still and the anomalies are still growing more positive there while region 4 drops off possibly due to lowering anomalies in that region and what does that do for both the WPAC, EPAC and Atlantic in terms of storms and hurricanes if the ENSO 4 drops, something that I thought to bring up because it seems to be happening even if temporary

If I remember right it will still shear out the MDR and Caribbean for the Atlantic but not as much while in the EPAC it really doesn't change things much from what El Nino would do anyway but its the WPAC that will have a change as it will bring a few more typhoons closer to the Island like the Phillipines and Japan but could be wrong on that

To answer your question, anything is possible but I think it is unlikely that we have seen the peak of this El Nino. There is still a lot of time between now and the time of year in which El Nino events tend to rapidly decay. Most dynamical models are showing an increase in strength to continue at least through summer. CFS and ECMWF are showing a more substantial strengthening. Subsurface temps are still very warm and we are seeing a strong WWB that should continue into this week. This WWB should reinforce the warm subsurface temps and I feel there is a good chance we will see some warming at the surface in all nino regions in the coming weeks.

See 1997. The warm pool shrank dramatically in August, not just 2Cs but all. And noticeably, the +5 and +6 anomalies are growing and which completely contrary to your statement. 1982 was a surprise, like nearly everyone thought it would remain weak at best, yet it exploded to a super Niño by October. 1997 and 2015 are in the same footsteps, textbook WWBs, rapidly and steadily warming eastern Pacific and massive warm pool which keeps on growing - something we did not see last year. The WPac had seen 2 Cat 5s and crazy season for both NPac and SPac (Aussie), maybe three if Dolphin becomes one, and is because of the WWB materializing, also did not see in 2014 since we only had Ita and weak Faxai/Peipah.

I'd argue that the fact the anomalies are shrinking near the date line are an indication than we our losing that Modoki look. ENSO 4 IMO is the least important of all Nino regions.

This is crazy. +4C anomalies now surfacing and +1C anomalies cover up the entire equatorial central and eastern Pacific.

Indeed. Now, we have seen +4 and +5 anomalies starting/about to surface. They are growing. Niño 1+2 and 3 are warming, Niño 3.4 holding steady and Niño 4 cooling is an imminent sign of a 1997-esque El Niño coming. SOI too is tanking bigtime, now at around -45
