You sound like you've got some real knowledge there, PuterMan.
I thank you but unfortunately I really cannot say that is the case. I am an interested amateur and can no more predict the weather than the British
Met Office.
What I am saying is that in watching the weather we see what we call the jetstream 'blocking' our weather in winter - and to a degree in summer
latterly. Actually the term is wrong because what is blocking our weather - the passage of warm wet air across the Atlantic - is actually the polar
air mass of which the jetstream is the result at the boundaries. It is the marker of where the air mass currently lies.
In summer as we tilt towards the sun in the Northern hemisphere the polar air mass reduces and the jetstream moves North. The opposite happens in the
winter and the jetstream moves south thus exposing the areas North of it to the polar air. That is perhaps a simplistic view as the darn thing snakes
about all over the place!
For my own convenience I have listed the links to various pressure and jetstream maps that I collect on
this page so if you are interested you can see / collect them from there.

NOAA - The jetstream
The real crux of the matter is what actually causes the polar air mass to move down. Obviously it is because it gets colder firstly, but then you have
to ask what affects this? I believe that it may be the sun, and this has been suggested recently by scientists.
These winds are normally stopped by the jet stream but scientists have found that this bends at times of low solar activity allowing the cold air
through. The connection between the jet stream bending and solar activity is not fully understood.

The article is not a bad explanation in simple terms of what might be happening at present.
So how is this related to sun spots? Well sunspots are an indicator of the activity of the sun and of the wattage (heat/power) we receive per square
metre. Less output from the sun means a lower wattage and although it is only a small difference it does appear to have an effect.
The current solar max is having a job getting going and for only a year away from the supposed solar max the sunspot count is very low.
Spaceweather.com counts every little freckle as a sunspot and still peddles out the NASA figures (well it is run by a NASA scientist) and continually
ignores the criteria established to count sun spots counting many that do not qualify in terms of duration and darkness.
But fear not. NASA has come to the rescue.
The current solar minimum has been so long and deep, it prompted some scientists to speculate that the sun might enter a long period with no
sunspot activity at all, akin to the Maunder Minimum of the 17th century. This new result dispells those concerns. The sun's internal magnetic dynamo
is still operating, and the sunspot cycle is not "broken."

Unfortunately it dispells them only for the adherents to the NASA religion. As I exhorted earlier the examination of Landscheidt is an essential. To
get a different view of the sunspot count go here
"Laymans sunspot count".
Further if you want to get your head into sun cycles and how they affect us you could do worse than look at
Landscheidt Cycles Research
It definitely appears to me that the sun has an influence on the jetstream/polar air mass and upon the council decision to buy salt!! Maybe they have
started reading Landscheidt?
Our warmist brethren will tell us that the planet is warming, which overall it may be very slightly, and that the Arctic ice will melt any minute now
and the Arctic sea will be ice free. Now theoretically if this were to happen the polar air mass would not be as cold and the jetstream would remain
further north even in the winter leading to milder winters. As we are only too well aware this has not been the case recently.
I am not wanting to get into a climate change debate here, just to say that many things affect climate and in my honest opinion CO2 is one of the
least likely.
So, um where was I. Oh yes. No I am not an expert and to not have a vast store of knowledge. I just look at the weather charts and look at the
jetstream and see that it is below us and causing brass monkey weather. If the Landscheidt cycles research is right then we will have colder winters
for the next 20 years or so and they will not be accompanied overall by warmer summers. (There are always extremes. This does not preclude these.)
Essan said that the climate models predicted that warming would cause colder weather. Unfortunately as far as I can tell from looking into this the
models were tweaked after the event to show this. There was no mention of this before the cold arrived.
I don't trust computer models. I am a programmer.
