Early winter hopes and chat

Recommended Posts

Reading the Express article note the quote that December is showing conflicting signs so there may be milder and stormier conditions....yet the rest of winter shows none?  hmmmmmm  Madden wobbling?

Did you say that?

Just to add to what Roger is saying on OPI thread, my thoughts re the jetstream being more favourable are that a basic pattern over North America like last year is anticipated but with a more -ve AO signature.  I like the 1977 composite as a general idea that Steve MURR posted.  It opens oppotunities for both arctic and tropical maritime incursions to influence and at times take hold of the winter.

We also have a supportive easterly QBO this winter. 

 

BFTP or anyone else for that matter. I was trying to improve my knowledge and looked up the QBO on Wiki, it seems to imply that an Easterly QBO is bad for North West European cold winters?

Is there something amiss here?

They use the term westward and eastward which is confusing MS.

Westward is going west ie flowing from the east so negative or East QBO is how i understood it.Checked and link here-

http://dictionary.cambridge.org/dictionary/british/westward

 

so would ring true for eastwards, ie,westerly flow or positive QBO. :)

Its quirky explanation I think MS

 

Westward QBO = Easterly QBO

Eastward QBO = Westerly QBO

 

Example of quirkiness - Easterly winds move in a westward direction [from east to west]. westerly winds move in eastward direction [from west to east.]

 

Easterly or -ve QBO are defo better for blocking chances

 

Hope that helps

Er.....so in short, no one knows and it's too early to make any reliable predictions?

 

Well that's simply not good enough! :acute:

 

:p

 

Still the reality of the situation shan't stop the Express from scaremongering.

Nah, you'll be stranded in blizzard conditions this winter Lauren

Here is the thought's from WSI on the rest of Autumn and Winter from the September update, the October update will be issued later this month and will cover the first 2 months of winter

 

WSI: Widespread Above-Normal Temperatures to Continue Through Autumn

 

Evidence Mounting for Pattern Change toward Colder Weather in Late Winter

 

Andover, MA, 22 September 2014 — WSI (Weather Services International) expects widespread above-normal temperatures across Scandinavia, eastern and central mainland Europe and the UK for the October-December period, with below-normal temperatures confined to parts of Iberia and southern France.

According to WSI Meteorologist Dr. Todd Crawford: “The remains of Hurricane Edouard have helped to trigger a temporary pattern change towards much cooler temperatures across much of Europe this week. However, the bulk of the evidence suggests a return to the pattern of widespread above-normal temperatures that has been common for much of the past year. Our latest forecast for October reflects this idea, with below-normal temperatures forecasted to be confined to the far north and west of Europe as high pressure remains in control over central and southern Europe. Looking ahead towards winter, the bulk of the evidence suggests that there may be significant cold risk late in the winter, as the combination of various atmospheric/oceanic drivers (including El Nino) appear to be in consensus. On the other hand, the climate models are quite strongly suggesting another mild winter, so there is still significant uncertainty for the upcoming winter.â€

In October, WSI forecasts:

 

Nordic Region – Warmer than normal, except southern Norway
UK – Warmer than normal south, cooler north
Northern Mainland – Warmer than normal
Southern Mainland – Warmer than normal

In November, WSI forecasts:

 

Nordic Region – Warmer than normal
UK – Warmer than normal
Northern Mainland – Warmer than normal
Southern Mainland – Warmer than normal, except Iberia/southern France

In December, WSI forecasts:

 

Nordic Region – Warmer than normal
UK – Warmer than normal
Northern Mainland – Warmer than normal
Southern Mainland – Warmer than normal, except Iberia/southern France

WSI weren't to far off the money last winter - predicting a strong Polar vortex and warmest months of the winter being January and February, yet another forecast heading towards possibly another mild/mildish one.

Generally what we get every year though and as common as the coldest winter in 1 trillion years call by Madden.

So many of these forecasts are predicated on a continuing/strengthening Nino during the winter months - the amount of land and SST positive anomalies are huge.

The latest run of the CFS ENSO predictions might just be showing that the forecasts will need to be re-evaluated.

Easier to forecast mild/warm than it is a freezing cold winter, that's for sure

Dont know if this is the right thread for this, or if it makes sense at all. There is a huge area of cold ocean temperatures in the  Atlantic which seems to have disrupted the gulf stream. See link

http://earth.nullschool.net/#current/ocean/surface/currents/overlay=sea_surface_temp_anomaly/orthographic=-23.58,42.01,671 

I'm not the most meteorological literate person by a long stretch, but could this be a switch to a cooler Atlantic mutlidecadal oscillation? It is to my understanding also that even during a warm phase Atlantic mutlidecadal oscillation, it can temporarily switch to a cold one, see link.

http://upload.wikimedia.org/wikipedia/commons/b/b4/Atlantic_Multidecadal_Oscillation.svg

As you can see, the cooler phases coincide with the cold winter events here in the UK. You can see on the graph, a dip to a cool phase during 2010, the 60's, mid 40's and other years. 

If this is nonsense, then mods feel free to delete.

I think it's another decade at least before the AMO is due to switch to it's negative phase.

Must admit that isn't a great start to winter from the wsi update and seems to go along with the mets glosea model. Let's hope next update is abit better for cold

The WSI update was from September as was the MetO, there's an awful long way to go yet before any model latches onto any particular strong signal let alone the full three months of winter.

Thankyou, any thoughts on this cold area? Every action has a reaction and all.
