I don't have the article handy, but my recollection is that anomalous meridional flow during this time period led to warm air advection into the arctic (and compensatory cold air advection into the mid-latitudes) which would have ameliorated some of the cooling.

The arctic air that moved into the eastern half of the region during January and settled in place across much of the region through February made the warm start of the winter season finish as one that was colder than average.

A good point as arctic regions that are hit with warmer water streams will prevent sea ice extent while those with colder ones can massivly increase in volume when the air is cold enough though no growth would be visible from the top down view.

The warming effect of carbon dioxide is strongest where air is cold and dry, mainly in the arctic rather than in the tropics, mainly in mountainous regions rather than in lowlands, mainly in winter rather than in summer, and mainly at night rather than in daytime.

The United States is facing record - setting cold temperatures after an arctic blast of cold air traveled south.

Long story short, the polar vortex is the result of global warming changing the semi-permanent weather system over the arctic regions resulting in movement of cold air masses from the arctic region to parts of North America, such as Canada and, unfortunately, poor Buffalo.

The more sluggish and persistent those meanders, the more persistent the patterns of regional warmth where the jet stream pulls warm air northward, and the regional cold where it pulls arctic air south.

Recent intrusions of cold arctic air into the continents may be caused by aberrant behavior of the polar vortex.

Air temps in arctic are almost precisely the same as the average for the past 50 years — So it is unlikely air temps have created ice loss — BUT CONVERSELY — the increased open arctic water SHOULD be affecting the arctic air temp - but is not (large expanses of 1 degree C arctic water make it difficult for air temps to drop to minus ten C — but since that is what is happening, then in fact there must be much more cold air around to create «normal» arctic temps for this time of the yeAir temps in arctic are almost precisely the same as the average for the past 50 years — So it is unlikely air temps have created ice loss — BUT CONVERSELY — the increased open arctic water SHOULD be affecting the arctic air temp - but is not (large expanses of 1 degree C arctic water make it difficult for air temps to drop to minus ten C — but since that is what is happening, then in fact there must be much more cold air around to create «normal» arctic temps for this time of the yeair temps have created ice loss — BUT CONVERSELY — the increased open arctic water SHOULD be affecting the arctic air temp - but is not (large expanses of 1 degree C arctic water make it difficult for air temps to drop to minus ten C — but since that is what is happening, then in fact there must be much more cold air around to create «normal» arctic temps for this time of the yeair temp - but is not (large expanses of 1 degree C arctic water make it difficult for air temps to drop to minus ten C — but since that is what is happening, then in fact there must be much more cold air around to create «normal» arctic temps for this time of the yeair temps to drop to minus ten C — but since that is what is happening, then in fact there must be much more cold air around to create «normal» arctic temps for this time of the yeair around to create «normal» arctic temps for this time of the year)

Equatorward - moving air behind a cold front occurs in pools of dense high pressure known as polar highs and arctic highs.

Do GCM's «create» cold fronts and the arctic air flows when they run, or are they «static» heat exchange models only (radiation received and radiation released are obviously their «drivers»... But what happens after the air masses have been «driven» for the equal of one or two «years» — do we see flows in the tropics, mid-latitudes, and polar latitudes than resembles earth's circulation?

Every time I hear that explanation that less sea ice means arctic air can move south I think «Damn, it must have been cold in the Medieval Warm Period».

When the low shifts as far south as Newfoundland, a high develops over northern Greenland; this brings cold arctic air west from northern Europe to be warmed by the Norwegian Current and thus warm Greenland and North America rather than Europe.

As a massive blanket of arctic air brings twenty - year record cold temperatures to the United States, it's not surprising to see the Church of Global Warming in full - on shrieking panic mode, screaming at the top of their lungs that a blast of cold weather doesn't disprove their theories.

And that heat transfer from as yet unfrozen seawater may generate the higher arctic pressures that drive cold air masses southward.

By John Hayward — As a massive blanket of arctic air brings twenty - year record cold temperatures to the United States, it's not surprising to see the Church of Global Warming in full - on shrieking panic mode, screaming at the top of their lungs that a blast of cold weather doesn't disprove their theories.

Depending on how far east winter storm tracks travel up the east coast, the battle line between cold arctic air masses to the west and warm Atlantic air to the east causes significant temperature changes.

Rather than flow around the arctic in a circular manner, the movement of the cold air becomes wavier, bringing the mass further and further south (see the pictures above).

And, once the summer season is passed, the ever - colder Arctic air masses remove even more heat from the under - ice water up through the sea ice by conduction into the -25 deg arctic air.

Applicability — all hygro - thermal regions except subarctic / arctic — in cold and very cold regions the thickness of the foam sheathing should be determined by hygro - thermal analysis so that the interior surface of the foam sheathing remains above the dew point temperature of the interior air (see Side Bar 2)

The «Beast from the East» was the name given by the media to an unusual weather pattern which saw warmer that average temperatures over the arctic sending colder air further south than normal, resulting in much of western Europe being hit with sustained low temperatures and heavy snow, blown in from Siberia.

Therefore, the effect of warming in the arctic is cooling at the lower latitudes, from increased albedo from clouds and snow, and transportation of colder air from the arctic.

We're seeing weirder, wilder, more extreme weather (and yes, the East Coast blizzard has its roots in warming as well; warmer water means more moister evaporates into the air, and when that meets cold arctic air you get even more snow).
