a crappy Pacific is typical in Nino Decembers. the one difference with this one compared to previous strong/super Ninos is the persistent -NAO blocking showing up. this is usually not a feature of events this strong and may signal increased blocking later this winter
-
honestly, just seeing the strong -NAO/-AO this early really bodes well for the rest of winter. it's a pretty strong departure from previous strong/super Ninos. AK is similar, but the polar domain is not. given that the -AO/-NAO is going to be a big factor, it'll set us up if we do pull off a -NAO Dec
-
if we had the Dec 4-6 pattern in Feb it would be so much more favorable with more cold air and shorter wavelengths. it's too early to rely on a lack of Arctic air
-
persistence forecasting will fail you when you need it to be right the most. that's the issue with it
-
as others have said, I don't think there's been a single person that's called for a cold December. in fact, many have called for a very warm month, including myself. it's just that the -NAO and weak SPV correlate to more blocking later in the winter
-
also talk about sanctimonious, holy shit. if you don't value the inputs in here, why post here? to just grace us with your galaxy brain? do you think us mere mortals could possibly understand your superior forecasting methods?
-
LOL are you serious? do you know what the MJO is?
-
if that ridge can find a way to poke into AK it really changes things up. allows colder air to sink into the trough
-
favorable trend in the PNA over the last cycle or so
-
i would like to see the backside vort dig more. i think it’s probably still too early given the lack of fresh polar air a month later and we would be talking
-
this is very close. nice 50/50 in place too
-
would be nice if there was enough wave spacing for the backside wave to amplify
-
it's too early for anything but an ideal pattern. hell, it doesn't even snow up here in coastal NJ until the 15th or so, let alone near you guys. the last couple weeks is a different story, but we have no idea how those weeks are going to shake out
-
this explanation makes sense, as the strong IOD leading to forcing in P3 is a typical strong Nino response. it's not Nina forcing
-
2018-19 was a weak Nino. I don't see why the same would occur during a borderline super event. this is a completely different year
-
do we need +4C anomalies over the Pacific in order for El Nino forcing to be felt? i truly do not see why there is so much discussion as if this Nino is failing and we're just stuck in a La Nina. it makes zero sense. this event is going to top out at like +1.8C
-
we are in a well coupled borderline super Nino. what do some of you think needs to happen? the discourse is as if we're still in a La Nina
-
you're telling me
-
that's silly. that's how El Ninos usually go. we've just had 5 Ninas in the last 7 years, so people have forgotten how they usually work. there is no meteorological reason that we would spend most of the winter in 4-5-6 the warmest water is also still over the central Pacific. SSTs also only really help feed back on atmospheric processes, they don't drive them
-
MJO caught got in 3-4-5 but it'll progress into more favorable phases over the next couple of weeks
-
the thing is that the passes through warmer phases are weaker and quicker than they are during Ninas. but they are still going to happen sometimes, especially early in the year
-
yes, generally. the EPS shows this progression back into 7-8-1 well a couple intrusions into 4-5-6 are going to happen early on in the year before the Nino is truly established. this intrusion was actually well forecast... models saw it around a week ago
-
I would still be encouraged seeing significant -NAO blocking this early, as well as a much weaker than average SPV. these are known to help lead to blocking later in the winter, especially in -QBO/Nino regimes. the Pacific is usually the issue in El Nino Decembers
-
this kind of pattern may cut it in like mid Jan through Feb, but it's too early to compensate for a less than ideal Pacific luckily, it really doesn't snow much before the 15-20th anywhere near the coast, so it's not like we're really missing out on much
-
that is true, but they are really all that we have
