A strong modoki is perfectly fine...it just doesn't have the SNE ceiling that a weaker event does bc the STJ is more prevalent than the N stream. Think 2009-2010, but we would likely do better than we did that season because we were very unlucky. Highest snowfall anonalies would be expected across the mid atl, though....probe to big Miller Assholes.
Keep in mind when I say "strong" modoki....I mean like peak ONI of 1.5 or 1.6C....not super nino..those are canonical or basin wide deals. Modoki has a ceiling due to the dynamics of the Walker Cycle.
Agree.
Ironically enough, I think the only reason this la nina won't end up strong is because it stagnated throughout the year. If it had abated and then redeveloped, it would have been better suited to link with the IOD and would have really gone to town.
I actually don't think the IOD and nina are coupled....according to research, the IOD isn't directly triggered by la nina unless it's a new event that develops by early summer...year long and late developing events interact differently with the ambient atmosphere over the tropical Pac.
This is a big reason why I think the rug gets pulled out quickly this winter, regardless of the state of the subsurface in August. This will serve to give el nino a real head start and it will at that point couple with the IO next summer...probably inducing another negative event.
I'm confident it will be at least moderate...maybe even strong, but it won't be a super event...modokis do not do that due to the currents associated with the dynamics of the Walker Cycle.
I think it will be like 57-58, 86-87, 02-03, 09-10.
It's really tough to get big rain AND win from a tropical system at this latitude at any given locale..exceedingly rare due to extratropical transition.
