The models don't even come close to replicating the complexity of just ENSO which currently has nina 1 through 4 regions and will likely have a 5 and 6 region within a few years.

A multi-variate index of ENSO which uses SST and winds.

Showing that the plateau is an ocean phenomenon directs one to the longer term ocean cycles such as ENSO which undermines the «global warming has stopped» impression.

I would guess most of the «step function» is actually those high southern latitudes reacting to ENSO which has generally been a lot more negative since 2007 than the period 1981 - 2006.

By this I mean, does it matter whether the 20thC was dominated by a pattern of ENSO which over that period produced a statistical effect, the PDO, which could be summarised as being 2 + ve's and one - ve.

nigelj @ 44, I delayed replying to you as in considering measurments of ENSO which I had assumed would all show a significant increase post-1980, I note that ONI has remained as flat as a pancake 1950 - to - date.

Not exact matches

The cup concept is based on Stora Enso's specially developed paperboards with high - barrier coatings, which protect the food content against moisture, oxygen and grease.

Stora Enso has just signed an agreement to divest the business and assets of its Swedish subsidiary Stora Enso Re-board AB, a producer of rigid paperboard for expositions and displays, to Culas AB, which is partially owned by the current managing director of Stora Enso Re-board AB, John - Åke Svensson.

The airtight paperboard cup was created by Stora Enso, which also produces the material from which it is made.

It also supports the ongoing MFC investment which will meet customer demand of products made with less raw materials (source reduction), enhanced strength, light weight and renewable barrier materials,» says Annica Bresky, head of Stora Enso's Consumer Board division.

The combined effects of El Niño (ENSO) and the North Atlantic Oscillation (NAO), both of which are naturally occurring climate processes, drove the recent hot spot, according to the study.

That's in line with a recent Japanese study, which looked at fossilised corals and also found evidence of an active ENSO in the Pliocene (Nature, DOI: 10.1038 / nature09777).

The El Niño - Southern Oscillation, or ENSO, is a naturally occurring climate cycle in which sea - surface temperatures in the equatorial Pacific Ocean fluctuate.

«We can't say which way ENSO is going to change yet,» Carré says.

In addition, global sea level can fluctuate due to climate patterns such as El Niños and La Niñas (the opposing phases of the El Niño Southern Oscillation, or ENSO) which influence ocean temperature and global precipitation patterns.

For another odd example, look at NASA's JPL press release, Dec 9, 2008, which discusses ENSO and the PDO as causes of local climate change — and doesn't mention global warming:

The paper's researchers, led by U.C. Davis marine biologist Patrick Kilduff, explain that the NPGO — which is largely driven by a flavor of the El Niño Southern Oscillation (ENSO) that produces warming in the tropical central Pacific Ocean — has become more common in recent decades.

... The finding indicates that the primary driver of climate like the south - westerlies that brings monsoon into the country from South Atlantic Ocean, the north - easterlies that lead to Tropical dry climate in the North and the ITCZ, which is sandwiched between the air masses, could be affected by changes in ENSO events.

The another most important climate variation is El Niño — Southern Oscillation (ENSO) events, which impact the global oceanic and atmospheric circulations which thereby produce droughts, floods and intense rainfall in certain regions.

However, the latest ENSO MAX was tempered to some degree by the PDO which helped ensure a blocking ridge of high pressure which did not allow much needed drought busting rain through.

Here, we show that the effective solar radiation (ESR), which includes the net solar radiation and the effects of volcanic eruption, has modulated this decadal ENSO - like oscillation.

Looking at the global CO2 dataset, current smoothing obscures a rather dramatic connection to ENSO, which I find truely bizarre.

Recently some scientists have postulated that the ENSO is impacted by solar activity, which currently is at a low (earth - cooling) level.

What they are not due to is the Pacific Multidecadal Oscillation (which is captured by the ENSO signal) or the Atlantic Multidecadal Oscillation (which does not have a suitable pattern to explain the phenomenon).

Having said that, if you look at this model of the ENSO adjusted temperature responce to forcings, you will see to large temperature spikes around 1939 and 1945 that are not accounted for by the model and which also contribute to the negative slope.

This result is in strong contrast with two decades of peer - reviewed research which find ENSO has little influence on long - term trends.

The fact that the observations have a «memory» from month to month (because the ocean is slow to change temperature) allows us to predict the annual mean from the year - to - date average (which implicitly includes the ENSO effect).

Similarly, many studies that attempt to examine the co-variability between Earth's energy budget and temperature (such as in many of the pieces here at RC concerning the Spencer and Lindzen literature) are only as good as the assumptions made about base state of the atmosphere relative to which changes are measured, the «forcing» that is supposedly driving the changes (which are often just things like ENSO, and are irrelevant to radiative - induced changes that will be important for the future), and are limited by short and discontinuous data records.

At this time the E-W sea surface temperature gradients in both the Pacific and Indian Oceans increased [29], [31] intensifying the E-W moisture transport in the tropics, which greatly increased rainfall variability both on a precession and an ENSO (El Niño Southern Oscillation) time - scales.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

A 2,400 mAh battery provides power to the device which Enso claims is good enough to keep things going for 5 to 7 hours.

I have seen a couple of papers, admittedly only in the blogosphere, which try and model the bit between climate change and weather based on AMO ENSO and CO2.

However, the temperature as an added signal which is either a cooling or warming one based on current «weather» influenced by ENSO inter alia and this additional «weather» signal in the temperature record is only averaged in the models if included at all.

In a series of papers, we've shown that the warmer temperatures observed over the WAIS are the result of those same atmospheric circulation changes, which are not related to the SAM, but rather to the remote forcing from changes in the tropical Pacific: changes in the character of ENSO (Steig et al., 2012; Ding et al., 2011; 2012).

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

These attempts give much better fits than ENSO plus C02 alone and suggest the CO2 component is nearer 0.7 c for a doubling which is below the low end of IPCC by quite a lot.

ENSO changes the cloud cover and water vapour amounts and so you would expect it to affect the Top - of - the - atmosphere radiation balance which changes the overall amount of heat in the system.

Obviously the confidence with which we can do this is dependent on the quality of the model we use to turn and ENSO Index into a global temperature signal but progress can be made.

Starting with that which we are most sure of and working down, we have WM - GHGs, Insolation, ENSO, and volcanoes.

Your first differencing removes the trends for the large part and so restricts you to short term variability — much of which is related to hidden variables in your analysis (i.e. ENSO, volcanic AOD etc.), thus causality is going to be tricky.

Note that the variation in sea level due to ENSO is only a few mm, really small compared to both the longer - term anthropogenic trend and to the local variations in sea level in the Pacific which can be even decimetres in places.

In an orgy of pointless nit - picking he's denied that ENSO can be characterized as a «forcing,» which of course means I'm a hopeless fool for making such an outrageous assumption.

What Knutson et al are asking us to do in essence is to put all that aside (because, they argue — in short — that its not the warming but the pattern of warming that matters here) and instead take on faith the perhaps not - much - more - than 50/50 proposition that the mean changes in ENSO state and variability projected by the IPCC multimodel ensemble (which are a key determinant in the projected future Atlantic TC activity) should be trusted.

Given the complexities of NAM / NAO, ENSO, sea ice, and Siberian snow, is it possible to know which are chickens and which eggs — or irrelevant?

Here is the detrended AMO index which has much longer cycles of 25 years or so but shows much less overall variability than the ENSO has (+ / -0.6 C versus the ENSO at + / - 3.0 C).

IF you're addicted to which year comes in 1st and second and third, etc like the media seems to be, then ENSO variations play a large part in that, but it is very small compared to the longer term (~ 0.7 - 0.8 C) trend.

Note also that when you do a PCA decomposition of the total sea level field (as done, e.g., in Church and White), the ENSO effect goes mostly into the next - in - line PCA (their number 1) and its EOF, which indeed looks like an ENSO type pattern (their figure 2 top right).

I take «threshold» to mean that GHG forcing could alter some natural variability like the Arctic Oscillation (which spends more and more time in its positive mode, increasing heat transport from mid-latitudes) or ENSO (more frequent or stronger El Nino events).

And yes, there is such evidence — in the predicted response to volcanic forcing, the ozone hole, orbital variations, the sun, paleo - lake outbursts, the response to ENSO etc. that all show models matching the observations skillfully (which is not to say they match perfectly).

Let's ignore NASA gmao ensemble for ENSO and instead eyeball a prolonged La Nina episode for 2011, which decays into 2012 giving neutral conditions:
