Sentences with phrase «arctic warming patterns»

Not exact matches

It is almost certain that the strange extreme weather patterns now observed throughout the northern hemisphere are related to this arctic warming and the consequent weakening of the jet streams that lie between the arctic and the more temperate northern lands.

I would say that's weather not climate change but I already got the lecture on how global warming causes freezing in the prairies by disrupting wind patterns so more cold air gets drawn down from the arctic warming it more so ice melts more, or some such folderol.

And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...

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.

Warm Arctic, cold continents: A common pattern related to arctic sea ice melt, snow advance, and extreme winter weather

While there may well be differences in the regional character of the arctic warming of the early 20th century, and the arctic warming of the late 20th century, I don't think that Dr. Meier really answered Mr. Goddard's question about the possibility of a cyclic pattern in both warming periods.

To summarise the arguments presented so far concerning ice - loss in the arctic basin, at least four mechanisms must be recognised: (i) a momentum - induced slowing of winter ice formation, (ii) upward heat - flux from anomalously warm Atlantic water through the surface low ‐ salinity layer below the ice, (iii) wind patterns that cause the export of anomalous amounts of drift ice through the Fram Straits and disperse pack - ice in the western basin and (iv) the anomalous flux of warm Bering Sea water into the eastern Arctic of the mid 1990s.

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.

that described that warming in the arctic would lead to more snow (more water vapor, and though warmer, not warm enough so it would not snow, but instead snow more) later springs and the reversal of the very pattern that was warming, Such things take decades and centuries.

From what I have read, global warming may be changing the pressure and wind patterns in the arctic regions of the Earth.

But figure 2 shows the 1920 - 1939 anomoly as localized in the arctic, as if the energy was transferred there from further south, while in recent decades it is only a small part of a global warming pattern.

Considering that there were places in the Arctic this summer that were 7 to 10C warmer than average this past winter, while some of us in the eastern and southern US froze our tails off — we got a very unusual freeze in S. Texas — due to the strongly negative arctic oscillation (weather patterns go north to south instead of west to east), and considering that the data gaps are more in the Arctic and inaccessible places, not here, one would expect GISS to come up with a somewhat warmer average than Hadley & others this year.

Yes, we are breaking records in part because of local variability of the weather, in part because we just concluded a warming trend and in part because we are experiencing a la nina event / cool pdo as well as a change in the arctic oscillation and wind patterns.

But nothing like the catastrophe we have been led to believe, with many alarmists claiming there would be an ice - free arctic last summer due to global warming (in fact, much of the big decline in 2007 was due to changes in wind patterns, not temperature).
