The Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO), and El Niño - Southern Oscillation (ENSO) have all been found to significantly influence changes in surface air temperature and rainfall (climate) on decadal and multi-decadal scales, and these natural ocean oscillations have been robustly connected to changes in solar activity.

A warm AMO phase leads to an atmospheric warming limited to the lower troposphere in summer, while it leads to a negative phase of the NAO in winter.

A recent study of instrumental time series revealed NAO [North Atlantic Oscillation] as main factor for a strong relation between winter temperature, precipitation and river discharge in central Norway over the past 50 years.

At a recent conference, scientists explained how a major atmospheric circulation known as the North Atlantic Oscillation (NAO) was in a negative phase at the onset of the LIA, which amplified the cooling effect of a reduction in solar irradiance and volcanic activity.

The first collection of papers establishes that (a) decadal and multi-decadal ocean circulation patterns (AMO, PDO, NAO, ENSO) have significantly modulated precipitation and temperature changes in recent decades, and the second collection of papers confirm that (b) natural ocean oscillations are, in turn, modulated by solar activity.

NAO - has a related impacts on winter climate extend from Florida to Greenland and from northwestern Africa over Europe far into northern Asian region.

What is visible is the influence of the NAO... See: aerosols: model and stations compared.

... NA [North American] temperature is largely controlled by these three large - scale atmospheric patterns, i.e., the PNA [Pacific - North American pattern], ABNA [Asian - Bering - North American pattern] and NAO [North Atlantic Oscillation].

... We found significant correlations between the NAO signal and both the average annual loss (AAL) and the average seasonal loss (ASL)[due to floods], for all the countries analysed.

The North Atlantic Oscillation (NAO) is Europe's dominant mode of climate variability.

Furthermore, since the end of the 19th century, we find an increasing variance in multidecadal hydroclimatic winter and spring, and this coincides with an increase in the multidecadal North Atlantic Oscillation (NAO) variability, suggesting a significant influence of large - scale atmospheric circulation patterns.

The NAO (North Atlantic oscillation) is one of the most dominant modes of global climate variability.

Surprisingly, it turns out that features of solar activity have been related to El Niño and La Niña, also have an significant impact on the NAO.

But have a look at Kaspar and Cubasch simulation and the reconstructed European Eemian temperature distribution (link thanks to Tom Rees), looks more like a very strong NAO (AO / AMO?)

(Nao Ota)

(Nao Ota et al..

Courtship display of a male red - cheeked cordon - bleu (Uraeginthus bengalus) with normal and high - speed video camera (Nao Ota et al..

Furthermore, temperature fluctuations tend to be fairly coherent over large parts (there is an anti-correlation in the see - saw structure associated with the NAO, however).

Similarly, if as a number of recent studies suggest, anthropogenic climate forcing leads to a greater tendency for the positive phase of the North Atlantic Oscillation (NAO)[or related «Arctic Oscillation» (AO)-RSB- pattern, we would expect increased baroclinicity and storminess over a substantial region of the mid-latitude North Atlantic ocean and neighboring western Europe..

[Response: Well, something like a circulation changed forced by the NAO pattern (which may in turn be affected by greenhouse gases) might cause an increase in European air temperatures, which in turn would allow low level moisture to increase if there is enough moisture supply, which would then constitute an amplification of a signal driven remotely.

The impact of regional Arctic sea ice loss on atmospheric circulation and the NAO.

Chylek found a good correlation between one (1) Greenland station (Danmarkshavn) and global warming, according to him, without an influence of the NAO.

The westerlies in the Northern Hemisphere, which increased from the 1960s to the 1990s but which have since returned to about normal as part of NAO and NAM changes, alter the flow from oceans to continents and are a major cause of the observed changes in winter storm tracks and related patterns of precipitation and temperature anomalies, especially over Europe.

MASKED THEATRE The 50 - centimetre - tall, white plastic Nao humanoid (see photo) looks adorable.

Julien Gorrias, a «behavioural architect» at Aldebaran Robotics in Paris, France, which makes the Nao, had solved the same problem in his former life as a masked actor by using expressive body movements.

Through this work, past phases of the NAO could then be reconstructed back to 1600 AD, Cleary said.

The existence of positive NAO values during the months of March to August, when the grape is developing and maturing, reduced the capacity of obtaining top quality cava,» Raimundo Real told SINC.

The NAO value between March and August can be calculated in the actual wine harvest time, while the quality of the cava can only be valued two years later.

«The likelihood of obtaining a top quality cava is higher when the average value of the NAO is negative.

The location of this cave in the foreland of the East Carpathian Mountains means winter precipitation is modulated by the North Atlantic Oscillation (NAO), with wetter conditions influencing the availability of nitrogen within the surrounding forest system.

Using historical records of precipitation, a relationship between winter precipitation and NAO phases was established.

About a third of the 250 000 data users are not registered, says the NAO in a report published last week.

A pioneering new study has explored how Arctic sea - ice loss influences the North Atlantic Oscillation (NAO) weather phenomenon, which affects winter weather conditions in Northern Europe, in places such as the UK, Scandinavia and the Baltic states.

«This research indicates that although sea - ice loss does intensify the negative NAO, bringing more days of cold easterly winds, it also causes those same winds to be warmer than they used to be.

Because of this it has been reasonable to think that we would experience more severe winter weather if Arctic sea - ice loss intensifies the negative phase of the NAO».
