A new study led by the Georgia Institute of Technology provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study's findings could be used to improve seasonal forecasting of snow and temperature anomalies across northern continents.

Since the level of set a new record low in 2007, significantly above-normal winter snow cover has been seen in large parts of the northern United States, northwestern and central Europe, and northern and central China. During the winters of 2009-2010 and 2010-2011, the Northern Hemisphere measured its second and third largest snow cover levels on record.

"Our study demonstrates that the decrease in ice area is linked to changes in the winter Northern Hemisphere ," said Judith Curry, chair of the School of Earth and Atmospheric Sciences at Georgia Tech. "The circulation changes result in more frequent episodes of atmospheric blocking patterns, which lead to increased cold surges and snow over large parts of the northern continents."

The study was published on Feb. 27, 2012 in the online early edition of the journal . The research was supported by NASA and the National Science Foundation.

In this study, scientists from Georgia Tech, the and Columbia University expanded on previous research by combining observational data and to explore the link between unusually large snowfall amounts in the in recent winters and diminishing Arctic sea ice.

These maps show the differences in Arctic sea ice concentration relative to the long-term average for the winters of (A) 2007-2008, (B) 2008-2009, (C) 2010-2011 and (D) 2010-2011. The lowest levels of Arctic sea ice have been measured between 2007 and 2011, with the record low occurring in 2007. Credit: Georgia Tech/Jiping Liu

The researchers analyzed observational data collected between 1979 and 2010 and found that a decrease in autumn Arctic sea ice of 1 million square kilometers -- the size of the surface area of Egypt -- corresponded to significantly above-normal winter snow cover in large parts of the northern United States, northwestern and central Europe, and northern and central China.

The analysis revealed two major factors that could be contributing to the unusually large snowfall in recent winters -- changes in atmospheric circulation and changes in atmospheric water vapor content -- which are both linked to diminishing Arctic sea ice. Strong warming in the Arctic through the late summer and autumn appears to be enhancing the melting of sea ice.

"We think the recent snowy winters could be caused by the retreating Arctic ice altering atmospheric circulation patterns by weakening westerly winds, increasing the amplitude of the jet stream and increasing the amount of moisture in the atmosphere," explained Jiping Liu, a senior research scientist in the School of Earth and Atmospheric Sciences at Georgia Tech. "These pattern changes enhance blocking patterns that favor more frequent movement of cold air masses to middle and lower latitudes, leading to increased heavy snowfall in Europe and the Northeast and Midwest regions of the United States."

Diminishing Arctic sea ice can cause changes in atmospheric circulation that lead to a circulation pattern that is different than the "negative phase" of the Arctic Oscillation.

Blocking patterns favor more frequent movement of cold air masses to middle and lower latitudes, leading to increased heavy snowfall in Europe and the Northeast and Midwest regions of the United States.

In addition to analyzing observational data, the researchers also assessed the impact of the diminishing Arctic sea ice on atmospheric circulation by comparing the results of model simulations run with different sea ice distribution. They ran one experiment that assumed seasonally varying Arctic sea ice and utilized sea ice concentration data collected between 1979 and 2010. Another simulation incorporated prescribed sea ice loss in autumn and winter based on satellite-derived Arctic sea ice concentrations.

The simulations showed that diminishing Arctic sea ice induced a significant surface warming in the Arctic Ocean and Greenland/northeastern Canada, and cooling over northern North America, Europe, Siberia and eastern Asia. The models also showed above-normal winter in large parts of the northern United States, central Europe, and northern and central China.

The consistent relationships seen in the model simulations and observational data illustrate that the rapid loss of sea ice in summer and delayed recovery of in autumn modulates snow cover, winter temperature and the frequency of cold air outbreaks in northern mid-latitudes.

Huijun Wang and Mirong Song of the Chinese Academy of Sciences Institute of Atmospheric Physics and Radley Horton from the Columbia University Center for Climate Systems Research also contributed to this work.

Obviously, you haven't looked at a recent photo of the Arctic.

In the past several years, the decline of extent and thickness has exposed warmer and warmer water directly to the air, aiding convection.

In early February, Svalbard hit something like 12 or 13 record daily highs in a 15 day period, breaking previous records by several degrees in celsius.

Remove the ice, you have heat transport and convection from the surface to the atmosphere to enhance storms.

The water in this region is several degrees C above normal, and probably at least 1C above the previous records.

Lurker2358

The increased convection and snow fall in the mid lattitudes produces a negative albedo feedback, which serves to offset or possibly even cool the temperate zones under some conditions, i.e. Europe.

However, since this is only temporary and seasonal from cloud cover or snow packs, it is not big enough to offset the CO2 feed-backs, nor the positive feedback from loss of albedo in glaciers or sea ice.

This effect will only grow to certain limits before positive feed-backs completely overwhelm it due to continental melting day anomalies eventually becoming so high that snow can't form, or at least can't survive on the surface long enough to matter.

So if we quit pumping CO2 and other crap in the air, then it will come to an equilibrium.

If we keep polluting indefinitely, it would seem to eventually get over this "hump".

It's extremely complicated. Real world systems don't follow perfect pen and paper models.

Just last year, Oklahoma broke both the record high and the record low on the same day at the same location.

Nobody would expect that in any weather model, be it warming, cooling, or staying the same. that's just not something anyone would think to happen, but it did.

It snowed more in the past, at least 120 to 200 years ago, and beyond, but it was for different reasons, i.e. it was just colder, so a higher percentage of precipitation was snow.

What's happening now is the convection is much higher, which means there is more water available to produce storms, and then when jet stream lines up correctly, the snows are much heavier.

However, they immediately melt as fast or faster than before, due to increased average surface temperatures, even if record daily lows are set once in a while...

That's absolutely false.

13 of the 15 hottest years on record occurred in the past 15 years.

the temperature has roughly plateaued near the 1998 record, but that should not be interpreted as a down trend. 1998 was way hotter than any previous year on record.

You are cherry picking one year, 1998, and noticing that most of the years since then were slightly cooler, while ignoring the fact that all but 2 of the years since then are well above the previous records.

Some plateau effect in temperature rise is expected due to various stages of negative feedback mechanisms, as well as energy required to overcome phase changes of water.

Using 5 year running averages for ice volume.

1983: 14,820
1998: 12,640
2011: 5,780

total loss: 14,820 - 5,780 = 9,040
loss since 1998: 12,640 - 5,780 = 6,860

Percent of total lost since 1998: 75.88%.

that is to say, 75.88% of all ice lost in 5 year running averages volume, of the 32 year record, was lost since 1998.

44.69% of the total ice loss, in 5 year running averages, since 1983, actually happened in the past 5 years...

This is roughly consistent with a rate of net melting doubling every 5 or 6 years.

You see Tard Boy. Here on planet earth, you need water vapor to produce snow, and water vapor comes from evaporation.

So when it is very cold and there is little evaporation you get little snow.

But when it is just about the freezing point, which means relatively warm, you generally have lots of evaporation, and hence ample water vapor for snow.

The obvious is again sailing over your head NP. Winter temperature data for the contigous US, not overall yearly, not Alaska, just winter and only according to this one graph that is posted and labeled, but has no commentary attached. The overall yearly is a plateau between 1998 and 2011, a plateau higher than every year preceding it except for one. Your graph is not useful as it is for a season in a specific area. I could link summer temperature data for texas and oklahoma and show an average rise of over 7 degrees for the same time frame, but from that I wouldn't be idiotic enough to make the statement that "IT" (being earth) has warmed by over 7 degrees....but at least you attempted to find something different than the usual rhetoric....

If the average temperature dropped 4.2 degrees in the winter over the timeline of the graph, then for the statement that the US is cooling to be true, overall temperature measurements would have to reflect this drop. Since there hasn't been a drop in year round temperatures, the other seasons would have to offset this with warmer than usual temperatures.

VD: Yup. Pretty close to freezing


-28C is 28C below freezing.

On the coast.

In winter.

August is winter in the southern hemisphere.

VD: Dumber than dirt.

"There was actually way less snow in the US BECAUSE IT WAS WARMER." - Parker Tard

It is self evident that when temperatures are above freezing there is no snow.

It is also self evident that when temperatures grow increasingly colder there is less snow all else being equal.

Poor clueless Parker Tard.

The earth has warmed approximately 1.5'F in the last century. A change of -4.2'F every decade is ludacrous, and would drive almost every species (including humans) to extinction.

"-28C is 28C below freezing. On the coast. In winter. " - Parker Tard

Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months.

Poor mentally ill Parker Tard.

I have to wonder why Parker Tard's mental illness only seems to infect the minds of Conservativss.

What makes them prone to this psychosis?

Because what Conservatives conserve is the expenditure of neuronic energy.

VD claims this winter was warmer and therefore proves it snows more in warm winter. The US government says less snow because it was warmer.

VD claims the coast of Antarctica is warm because it is only -28C. Only the mentally or dishonest claim -28C is warm.

VD thanks for the amusement. People who believe in the CO2 cult are dumber than rocks.

Wrong again Tard Boy.

I almost never use the word proof outside of mathematics.

Since you have used it here and ascribed it to me, you are of course lying.

Nope. I never said that either.

But it does nicely illustrate the nature of your mental illness.

Poor Parker Tard. Just making up childish nonsense as he goes along.

Good god Lurker, when your not quoting scripture or praising cold fusion, you can be an extremely reasonable voice. The comments section is a better place when your making sense.

VD said both. Easy to find and read.

VD said neither.

Parker Tard, who has proven himself to be a congenital liar, can't support his lies so he provides no links.

Our findings support a previous study suggesting that the impact of anthropogenic climate warming on Arctic sea ice became detectable from the early 1990s onwards(19). The present decline in sea ice is occurring at a pace seen in earlier episodes, but the sustained trend (now nearly 50 years long) is unprecedented in the 1,450-year reconstruction period presented here.
