Bob Tisdale posted this animation over at WUWT., at this post:
The animation shows how the cold air draining off the Pole into Siberia didn’t only move west to Europe, but also spilled east into the North Pacific, dramatically cooling the waters over the past month.
You can see the modest La Nina extending off the west coast of South America, and also the “Warm Blob” shrinking and being pressed up against the coast of Alaska. However the cold water hasn’t been named, so I’ll call it the La Nina of the North, or “El Norte Nina”.
It will be interesting to see how long El Norte Nina lasts. I imagine it is a wrench in the works of long term winter forecasts, likely based upon the “Warm Blob”. If it persists it will likely represent an end to the “warm spike” in the PDO, and a return to a cold PDO, just as I forecast. I forecast it two years ago, and it didn’t happen, and I forecast it last year, and it didn’t happen, but now, at long last, the blind squirrel finds the nut.
(Actually there was a warm spike in the cold PDO of the 1950’s, and I was imagining the current warm spike would behave the same way, and last the same length of time. Fail. The current situation is unique, and the warm spike was far more powerful and lasted longer.)
The El Norte Nina fits nicely into my idea that we can’t have all the mild air rushing north to fuel the low pressure “Ralph” at the Pole, without having an exit route for all that air, bringing cold down to sub-polar regions. This year Eurasia has experienced a bitterly cold autumn, “unprecedented” in some places. I’ve been waiting for this autumnal pattern to flip into a winter pattern, but so far it is hanging tough. The map below shows the cold over Eurasia, with the cold pouring east into the Pacific over Japan. Of interest is the slot of warmth in the upper left. It is due to the latest incarnation of Ralph, which formed off the northeast tip of Greenland and crossed the Pole on the Atlantic side, finally crashing down into Eastern Russia. It’s odd when the “mild” air comes from the Pole, but that is how topsy-turvy the pattern is.
Looking ahead to next Tuesday, Mongolia gets a respite, but the cold gets incredible over central Russia, with temperatures forecast to be 35 degrees below normal. It looks like cold air is continuing to spill east over Japan, which likely would continue to fuel El Norte Nina.
To me this suggests another surge of mildness should be heading up to the Pole. So we first look at the current GFS anomaly map (produced by Dr. Ryan Maue over at the Weatherbell site [week free trial offered]).
Things indeed are mild up there, but not as mild as they are forecast to be next Tuesday.
Indeed, just as temperatures are 35 degrees below normal down in Siberia and Kazakhstan, they are 35 above at the Pole. In a few cases they may even be a bit above freezing, and I expect that will generate the usual hoop-la from the usual suspects. The DMI temperature-north-of-80°-latitude map will likely show yet another up-spike, perhaps even higher than the last one.
There will be further hoop-la about such a spike, and I feel there should be, but not because I feel the planet is warming. I feel it demonstrates our planet is spending heat like a drunken sailor, and will face one heck of a hangover in the morning, (the “morning” being midwinter.)
The next surge of warmth will come from the Atlantic and in some ways will be a repeat of where we left off last time I posted. Back then (November 7) an Atlantic-to-Pacific cross-polar-flow was bringing a spike of milder temperatures north of Greenland. (Ralph’s “signature”)
Besides creating a wrong-way-flow in Fram Strait, the rising mild air fueled yet another incarnation of Ralph himself.
Rather than heading up to the Pole, Ralph headed over to the Kara Sea, and I was thinking maybe the pattern was changing a little, and Ralph was merely a North Atlantic storm that happened to be displaced way, way, way to the North. I watched for high pressure to build at the Pole.
The high pressure did build, but the flow in Fram Strait remained a wrong-way flow, and that can lead to the reappearance of Ralph’s “signature.” And indeed today’s map shows a weak signature north of Greenland, and a weak Atlantic-to-Pacific cross-polar-flow starting, right where I was thinking high pressure might build. And….what is that dent of low pressure over the Pole? No! Not the ghost of Ralph, haunting me!
This really is a remarkable pattern, and a lot of fun to watch. I was expecting a pattern flip, and I guess El Norte Nina fits the bill. Not that I was expecting it to happen so quickly, (though I did say it would happen quickly, back in 2014), but I’ll call it a correct forecast, because I’m not able to say I’m right all that often, and even a blind squirrel wants a pat on the back every once in a while.
On the eleventh hour of the eleventh day of the eleventh month, 98 years ago, the guns stopped shooting and silence descended over Flanders Field. People really did believe men had fought the war to end all wars, and mankind would never be so foolish ever again. Alas, Hitlers arise, and some men must leave warm homes to defend us. May God bless them, and may God save us from ourselves.
