I might be going out on a limb here, but it seems like to combat the increase in temps, we need our PAC look to be substantially better than it used to. That's what made our rather frequent events in 13/14 and 14/15 work out pretty well. I mentioned this in the banter thread, but that necessity has to undoubtedly hurt us in Ninas, since for any high end WWA or WSW events (as pointed out by PSU) they require the favorable Atlantic to be our main lifeline to pull off those events. Yet if the pacific needs to be perfect to prevent a warm/wet and cold/dry regime, we're essentially dancing between both the PAC and Atlantic teleconnections. Like I said, I'm probably going out on a limb, but that's the main way I can see how most of our Ninos in the past decade have been near or above climo, while we've punted numerous good patterns in recent Ninas.
