Sentences with phrase «multidecadal variability»
"Multidecadal variability" refers to patterns or fluctuations that occur over a period of several decades. It means that there are changes or variations happening in a repeating pattern that can last for multiple decades. Full definition

Zhang, R., T. L. Delworth, and I. M. Held, 2007: Can the Atlantic Ocean drive the observed multidecadal variability in Northern Hemisphere mean temperature?
And consistent with multidecadal variability, during the previous negative PDO from 1940 to the late 70s, corrosive upwelled waters had similarly reduced survival of larval oysters in those bays.
To address these issues, we applied a semi-empirical approach that combines climate observations and model simulations to estimate Atlantic - and Pacific - based internal multidecadal variability (termed «AMO» and «PMO,» respectively).
Nonetheless, even if the substantial recent trend in the AO pattern is simply a product of natural multidecadal variability in North Atlantic climate, it underscores the fact that western and southern Greenland is an extremely poor place to look, from a signal vs. noise point of view, for the large - scale polar amplification signature of anthropogenic surface warming.
Ruprich - Robert, Y., F. Castruccio, R. Msadek, S. G. Yeager, T. Delworth, and G. Danabasoglu, 2016: Assessing the climate impacts of the observed Atlantic multidecadal variability using the GFDL CM2.1 and NCAR CESM1 global coupled models.
The thing is, it's not enough to look at a 10 year period in isolation and I would certainly hesitate to draw conclusions about multidecadal variability based on 10 years of data.
The observed Atlantic major hurricane frequency has exhibited pronounced multidecadal variability since the 1940s.
Observed Atlantic major hurricane frequency has exhibited pronounced multidecadal variability since the 1940s.
The cold season CEI indicates an increase in extremes since the early 1970s yet has large multidecadal variability
The reason this choice matters is that this bias correction will be applied to the 21st century simulations, and the bias corrections are useless if you are merely correcting for multidecadal variability that is out of phase with the observations.
The impact of North Atlantic - Arctic multidecadal variability on Northern Hemisphere surface air temperature
Given that, our best assessment of the relationship between the AMO surface pattern and the underlying THC variations is likely to come from analyses of long coupled model integrations with models that are known to produce multidecadal variability in the THC and an «AMO» of sorts.
The AWP multidecadal variability coincides with the signal of the AMO; that is, the warm (cool) phases of the AMO are characterized by repeated large (small) AWPs.
I also mentioned multidecadal variability in a comment on the webpage associated with the video in this article.
A multi-model simulation study shows that Atlantic Multidecadal Variability warming drives a modification of the Walker Circulation that creates precipitation anomalies over the whole tropical belt.
Using this method, the AMO [Atlantic Multidecadal Variability] and PMO [Pacific Multidecal Variability] are found to explain a large proportion of internal variability in Northern Hemisphere mean temperatures.
A NOTE ABOUT THE NORTH ATLANTIC Oceanic processes such as Atlantic Meridional Overturning Circulation (AMOC) and Thermohaline Circulation (THC) are normally cited as the cause of the additional multidecadal variability of North Atlantic SST anomalies.
A long time - scale is needed because significant multidecadal variability appears in numerous tide gauge records during the 20th century.
A significant component of unforced multidecadal variability in the recent acceleration of global warming
A focus of paleo reconstructions for the past 2000 years should be detecting multidecadal variability, rather than trying to convince that the recent decade is the warmest decade, etc..
«Recurring stratospheric vortex events create long - lived perturbations at the ocean surface, which penetrate into the deeper ocean and trigger multidecadal variability in its circulation.
This model's forced response agrees very well with the observed surface temperatures averaged over the North Atlantic, so in this model one doesn't need to invoke internal multidecadal variability to match these observations.
Nonetheless, even if the substantial recent trend in the AO pattern is simply a product of natural multidecadal variability in North Atlantic climate, it underscores the fact that western and southern Greenland is an extremely poor place to look, from a signal vs. noise point of view, for the large - scale polar amplification signature of anthropogenic surface warming.

Because this large multidecadal variability is not random, but likely recurrent based on its past behavior, it has predictive value.
Fluctuations in the AMOC have been linked to low - frequency variability of Atlantic sea surface temperatures, termed Atlantic Multidecadal Variability, with a host of implications for climate variability over surrounding landmasses.
