Long - range PCR is a method that allows for the amplification of much larger fragments of DNA than is possible with traditional PCR — fragments larger than 40 kilobases have been reported in long PCR, versus fewer than 10 kilobases for traditional PCR.

And atmospheric scientist James Screen of the University of Exeter in the United Kingdom warns that the «link between blocking and Arctic amplification is still very much open to debate.»

Typically, lasers require a much larger cavity that allows light to bounce back and forth between mirrors for it to become amplified into a laser (light amplification by stimulated emission of radiation).

This may help explain some of the changes that are not explained by the orbital curves in the other thread, especially the initiation of warming and cooling since the GCR effects can be much more powerful (partly forcing as postulated in the paper, but also amplification of the weaker orbital forcing).

The «uptick» in Arctic amplification is most worrisome, says Francis, because of the possible implications for extreme weather much further south.

Amplification requires careful calibration, as too much gain can lead to some of the biggest EMG amplitudes exceeding the maximum output voltage and thereby being «clipped», but too little gain can lead to some of the smallest EMG amplitudes being lost and not observed (Burden, 2007).

That's the problem with amplification, there can be a lot of distortion (which can sound really cool if your Jimi Hendrix, otherwise not so much).

Most past modeling experiments that investigated the atmospheric response to Arctic change only considered the loss of sea ice, which of course misses much of the effect of Arctic amplification.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

However, process engineers building electronic circuits, who invented feedback mathematics, tell us any loop gain much above zero is far too near the singularity — at a loop gain of 1 — in the feedback - amplification function.

Heat from Arctic amplification over normal conditions in these regions is much smaller than on the other side of the pack because the ice covered these seas longer this year; The heat added due to Arctic amplification probably less than 6... and with most of that in the Beaufort, and not in the Chukchi and E. Siberian.

Stott, et al., would have found a much larger and a more uniform and larger amplification factor had they also investigated the effects of lagging surface temperature with respect to solar radiation.

I felt she believed what she was saying but was left with the impression that she was pushing her own theory of arctic amplification and also the oceans absorbing the recent warming without any realisation that the statistics of extreme events appears to contradict much of where she is coming from.

Much of the Northern Hemisphere shows strong heat amplification with values above +1 C and rising in all the Latitudinal zones above 40 North.

We still have much more to learn about «Recent Arctic amplification and extreme mid-latitude weather,» as made clear in a Nature Geoscience paper (with that title) written by several of the leading researchers in the field, including Francis.

Much of the impacts we presently see are due to salt water invasion of low lying regions, nuisance flooding events, the amplification of storm driven tides, and increasing instances of what are now called king and emperor tides.

After 30 years of study the modeling of the soon to be repackaged amplification is not much better than it was at the start.

Really the big question for me, once aware of all in http://s24.postimg.org/rbbws9o85/overview.gif and much else, is whether or not coming cooling in the 21st century will end with a somewhat brief LIA - like event, or, via amplification of cooling through further albedo change from snow cover rise then, continue far longer into a non-little Ice Age afterwards..

On the solar subject, if you work out how much the TSI trend would have to be wrong for solar plus the terrestrial amplification found by Prof. Nir Shaviv http://sciencebits.com/calorimeter to be able to account for global warming, the answer is, not very much at all, and well within the uncertainty of TSI measurement.

The loss of sea ice has affected the temperature amplification but other factors seem to be involved, as the loss has been much more than any model has suggested.

Previously, it had been supposed that last winter's very cold conditions over much of the continental US was related to «Arctic amplification.»

In order to sex up CO2 greenhouse warming to a point that might make it scary the climate boffins invented, out of whole cloth with no empircal data to back it up, an imaginary «amplification» where a little CO2 warming increases greenhouse warming by water vapor by twice as much.

This may help explain some of the changes that are not explained by the orbital curves in the other thread, especially the initiation of warming and cooling since the GCR effects can be much more powerful (partly forcing as postulated in the paper, but also amplification of the weaker orbital forcing).
