Prediction: La Nada and a raging AO due to solar issues so very little snow and cold. Maybe an event around Valentines day.

Good for the winter golfers, bad for the winter plowers.

Discuss.

Swinging for the fences already trials huh? I think we should wait till atleast september to start making these predictions actually have some merit. I mean we havent even started meteorlogical summer yet lol.

Means nothing.

Its all about the blocking and the Nao. La Nina or El Nino just determine the size of the storm because of the southern vs. northern streams.

Give me blocking and a -nao in December and then we're talking.

No one can predict the nao more then 2-3 weeks in advance.

hopefully this will be as bad as your call for last winter...and LOL at winter calls in May

Sounds like reverse psychology to me, definite bad winter coming up!

We have nowhere to go but up from last winter's debacle, which is always going to be a bright side to a disastrous winter.

not true, several places had 15 inches or so of snow last year after the huge October storm. You could get a winter where there is no snow for anyone in the tri-state. From October through April.

Well I'm referring to the immediate tri-state area. I don't think that's ever happened for the area, even one snow shower is enough to give us a trace.

over done and you can see there is a trend to go back towards weak nina, so if you average it out, la nada.

Dont understand what you're saying, the hard data is already nearly exactly La Nada and almost every ensemble member takes it into Weak Niño territory. The mean of the ensemble members gets to values near 1.

Primary analogue is 01-02, secondary is 97-98, terciary is 68-69.

You post La Nada on top, and then 97-98 as an analog. You lost any shred of credibility with this post right there.

did i say my analogues were strictly enso based? There is a lot that go into analogues, not just enso.

Solar, lunar, volcanic, qbo, mjo, ebo, nao, all are factored in there.

Anyone with any credentials, period, knows that if you're forecasting a near-neutral state you ALWAYS AUTOMATICALLY throw out years that were strong ENSO years, EVEN IF the pattern matches your forecast.

Agreed -- also have you seen the blocking developing this week over Canada and Greenland? Holy moly. Positive anomalies over the entire blocking region and then some.

we had a ton of blocking last summer, and look what happened? not a good predictor of the NAO state next winter. We were blocky all the way until September and we never really got it back, and when we did, on the wrong side of the globe.

Actually Trials, a weakly active sun as we are seeing now leads to a -AO, and cold winters in the United States and Western Europe, so your logic is totally flawed.

http://www.nature.co...l/ngeo1282.html

An influence of solar irradiance variations on Earth’s surface climate has been repeatedly suggested, based on correlations between solar variability and meteorological variables1. Specifically, weaker westerly winds have been observed in winters with a less active sun, for example at the minimum phase of the 11-year sunspot cycle2, 3, 4. With some possible exceptions5, 6, it has proved difficult for climate models to consistently reproduce this signal7, 8. Spectral Irradiance Monitor satellite measurements indicate that variations in solar ultraviolet irradiance may be larger than previously thought9. Here we drive an ocean–atmosphere climate model with ultraviolet irradiance variations based on these observations. We find that the model responds to the solar minimum with patterns in surface pressure and temperature that resemble the negative phase of the North Atlantic or Arctic Oscillation, of similar magnitude to observations. In our model, the anomalies descend through the depth of the extratropical winter atmosphere. If the updated measurements of solar ultraviolet irradiance are correct, low solar activity, as observed during recent years, drives cold winters in northern Europe and the United States

funny, because there is a large contigent who use opposite enso states when looking at analogues, the guy down in DC is one of them.

funny, because I don't remember saying anything about what the sun is doing this moment, i am speaking about where its going, and a strongly active sun is coming.

other data has a stonger nino so when you throw it all together, it looks like la nada, especially given how some even show a nina developing.

So what did you mean by "a raging AO due to solar issues?"

I take it you are unaware that the sun's activity has largely decreased over the last several years, and we are going into a quiet solar period not seen in over 400 years?

there are indications the suns activity is going to be picking up. I do believe the mighty HM has made reference to this.

There is NOTHING that shows a Nina developing. Some data show the Nino strengthening, approaching moderate, and then leveling off at weak Nino. NOTHING shows a Nina developing. Even IF you extrapolated, that NIna probably wouldn't develop until summer 2013 on the most aggressive data.
