Sweden prepares for another deep freeze

Cold weather coming to sweden in December? Well I never.

And it will last until the end of the year? All of 3 days!

Come on guys.

Wot happened to al Gore's global warming? Seems to have vanished into thin air.

Its been raining today :)

Frankly have seen tempratures in this range since last year and wonder how ppl used to live here about a century ago with no central heating.. am sure winters would have been a long holiday...

I reckon a century ago, out in the sticks,like the squirrels, they must have had their horde of grub and their nuts stashed away in a nice warm handy place, before hibernating, and only occasionally waking up to enjoy their porridge oats..

Seems this cold snap has been right through Europe,even close to my Spanish location some roads have been blocked with snow earlier than usual.

Global warming,not so sure.

If the Arctic ice has melted,maybe the North Pole has decided to move South....lol.

Read the following this morning, seems to be on the money...

The Arctic Oscillation Index goes strongly negative

In the last month, the Arctic Oscillation Index (AO) has gone strongly negative. You can see that it headed to it's negative peak right about the time the Copenhagen Climate Conference started, so it is no wonder that they ironically experienced cold and snow there. It is also a setup for the record snow and cold Canada and the USA has seen recently.

From NSIDC:

The Arctic Oscillation refers to opposing atmospheric pressure patterns in northern middle and high latitudes.

The oscillation exhibits a "negative phase" with relatively high pressure over the polar region and low pressure at midlatitudes (about 45 degrees North), and a "positive phase" in which the pattern is reversed. In the positive phase, higher pressure at midlatitudes drives ocean storms farther north, and changes in the circulation pattern bring wetter weather to Alaska, Scotland and Scandinavia, as well as drier conditions to the western United States and the Mediterranean. In the positive phase, frigid winter air does not extend as far into the middle of North America as it would during the negative phase of the oscillation. This keeps much of the United States east of the Rocky Mountains warmer than normal, but leaves Greenland and Newfoundland colder than usual. Weather patterns in the negative phase are in general "opposite" to those of the positive phase, as illustrated below.

Over most of the past century, the Arctic Oscillation alternated between its positive and negative phases. Starting in the 1970s, however, the oscillation has tended to stay in the positive phase, causing lower than normal arctic air pressure and higher than normal temperatures in much of the United States and northern Eurasia.

As we see in this graph below, we've seen more red (positive) than blue (negative) phases of the AO in the last 30–40 years. Whether this is short period negative excursion or the start of a longer trend is unknown.

I like DaveN's comment. For Pete's sake, this is Sweden! Each winter it gets cold and snows. I know. My grandfather who came to America in 1919 told me so countless times when I was a kid. We lived in Chicago and no matter how much snow or cold we had, he'd always say, "You should see how it is in Sweden!" I realize now he was exaggerating, but the point is still valid.

It seems to me that there is lack of basic knowledge on the subject of the Atlantic conveyor belt, so I have attached a link which should explain it all
