... On decadal to multidecadal timescales, the Pacific Decadal Oscillation (PDO), the Atlantic Multidecadal Oscillation, and the Atlantic tripole mode determine the variability of rainfall over India (Sen Roy et al., 2003; Lu et al., 2006; Zhang and Delworth, 2006; Li et al., 2008; Sen Roy, 2011; Krishnamurthy and Krishnamurthy, 2014a, 20multidecadal timescales, the Pacific Decadal Oscillation (PDO), the Atlantic Multidecadal Oscillation, and the Atlantic tripole mode determine the variability of rainfall over India (Sen Roy et al., 2003; Lu et al., 2006; Zhang and Delworth, 2006; Li et al., 2008; Sen Roy, 2011; Krishnamurthy and Krishnamurthy, 2014a, 20Multidecadal Oscillation, and the Atlantic tripole mode determine the variability of rainfall over India (Sen Roy et al., 2003; Lu et al., 2006; Zhang and Delworth, 2006; Li et al., 2008; Sen Roy, 2011; Krishnamurthy and Krishnamurthy, 2014a, 2014b, 2016b).

Here we demonstrate that the multidcadal variability in NHT including the recent warming hiatus is tied to the NAT - NAO - AMO - AMOC coupled mode and the NAO is implicated as a useful predictor of NHT multidecadal variability.

«Multidecadal variability of Atlantic tropical cyclone activity is observed to relate to the Atlantic Multidecadal Oscillation (AMO)-- a mode manifesting primarily in sea surface temperature (SST) in the high latitudes of the North Atlantic.

Patterns of variability that don't match the predicted fingerprints from the examined drivers (the «residuals») can be large — especially on short - time scales, and look in most cases like the modes of internal variability that we've been used to; ENSO / PDO, the North Atlantic multidecadal oscillation etc..

Specifically, the claim was made that temperatures in Churchill, Manitoba (close to the center of the Western Hudson Bay population of bears) had not risen, and that instead, any multidecadal variations in temperatures affecting the bears were related to the Arctic Oscillation (AO), a mode of natural variability.

The Atlantic Multidecadal Oscillation (AMO) or Variability (AMV) is a mode of low frequency (i.e., decadal to multidecadal) climate variability centered over the North AtlMultidecadal Oscillation (AMO) or Variability (AMV) is a mode of low frequency (i.e., decadal to multidecadal) climate variability centered over the North AtlaVariability (AMV) is a mode of low frequency (i.e., decadal to multidecadal) climate variability centered over the North Atlmultidecadal) climate variability centered over the North Atlavariability centered over the North Atlantic basin.

They do a poor job at simulating the observed modes of natural internal climate variability (e.g. the multidecadal ocean oscillations).

The Atlantic Multidecadal Oscillation (like other ocean oscillations) is a climate pattern with a mode of variability, which seems to naturally occur regardless of atmospheric CO2 levels.

Other well - known modes of variability include: The Antarctic oscillation; The Arctic oscillation; The Atlantic multidecadal oscillation; The Indian Ocean Dipole; The Madden — Julian oscillation; The North Atlantic oscillation; The Pacific decadal oscillation; The Pacific - North American teleconnection pattern; The Quasi-biennial oscillation.

Moreover, 370 years of tropical cyclone data from the Lesser Antilles (the eastern Caribbean island chain that bisects the main development region for landfalling U.S. hurricanes) show no long - term trend in either power or frequency but a 50 - to 70 - year wave pattern associated with the Atlantic Multidecadal Oscillation, a mode of natural climate variability.

Given that the past 30 — 50 years is a relatively short period for evaluating long - term trends, the SST trends themselves could be viewed as a manifestation of large - scale modes of multidecadal Pacific variability (e.g. Zhang et al. 1997; Deser et al. 2004) or as part of the century scale positive SST trends associated with climate change (e.g. Deser et al. 2010); it is likely that both multidecadal climate variability and climate change have contributed to the SST trend pattern evident in Fig. 9 and used to force the model.

b) failure of the climate models to predict a > 17 year plateau raises questions about the suitability of the climate models for detection and attribution analyses, particularly in terms of accounting adequately for multidecadal modes of climate variability...

The modes of natural internal variability of greatest relevance are the Atlantic modes (AMO, NAO) and the Pacific models (PDO, often referred to as IPO) of multidecadal climate variability, with nominal time scales of 60 - 70 + years.

Getting these multidecadal variations correct in the reconstructions would be very valuable in understanding the modes of natural internal climate variability, and to what extent such variations might explain 20th century climate variability.

And finally, attribution studies can't simply rely on model simulations, since model simulations (even if they capture the correct spectrum of variability) won't match the observed realization of the multidecadal modes in terms of timing.

That leaves the North Atlantic, but it has another mode of natural variability called the Atlantic Multidecadal Oscillation...... which is why it doesn't cool between the strong El Niños.
