Decadal variability is a notable feature of the Atlantic Ocean and the climate of the regions it influences. Prominently, this is manifested in the Atlantic Multidecadal Oscillation (AMO) in sea surface temperatures. Positive (negative) phases of the AMO coincide with warmer (colder) North Atlantic sea surface temperatures. The AMO is linked with decadal climate fluctuations, such as Indian and Sahel rainfall, European summer precipitation, Atlantic hurricanes and variations in global… 
The Atlantic Multidecadal Oscillation without a role for ocean circulation
The results suggest that the AMO is the response to stochastic forcing from the mid-latitude atmospheric circulation, with thermal coupling playing a role in the tropics.
Global linkages originating from decadal oceanic variability in the subpolar North Atlantic
The anomalous decadal warming of the subpolar North Atlantic Ocean (SPNA), and the northward spreading of this warm water, has been linked to rapid Arctic sea ice loss and more frequent cold European
Multidecadal variability and climate shift in the North Atlantic Ocean
Decadal variability of ocean heat content (OHC) and temperature trends over ~60 years in the North Atlantic Ocean were analyzed using a new high‐resolution ocean climatology based on
The Evolving Role of External Forcing in North Atlantic SST Variability Over the Last Millennium
Atlantic Multidecadal Variability (AMV) impacts temperature, precipitation, and extreme events on both sides of the Atlantic basin. Previous studies with climate models have suggested that when
The signature of low‐frequency oceanic forcing in the Atlantic Multidecadal Oscillation
The Atlantic Multidecadal Oscillation (AMO) significantly influences the climate of the surrounding continents and has previously been attributed to variations in the Atlantic Meridional Overturning
Gulf Stream Variability in the Context of Quasi‐Decadal and Multidecadal Atlantic Climate Variability
The Gulf Stream plays an important role in North Atlantic climate variability on a range of timescales. The North Atlantic is notable for large decadal variability in sea surface temperatures (SST).
Recent Progress in Understanding and Predicting Atlantic Decadal Climate Variability
Preliminary successes in the field of initialized Atlantic climate prediction confirm the climate relevance of low-frequency Atlantic Ocean dynamics and suggest that useful decadal climate prediction is a realizable goal.
The necessity of cloud feedback for a basin‐scale Atlantic Multidecadal Oscillation
The Atlantic Multidecadal Oscillation (AMO), characterized by basin‐scale multidecadal variability in North Atlantic sea surface temperatures (SSTs), has traditionally been interpreted as the surface
Contributions of Interdecadal Pacific Oscillation and Atlantic Multidecadal Oscillation to Global Ocean Heat Content Distribution
AbstractRegional sea surface temperature (SST) mode variabilities, especially the La Nina–like Pacific Ocean temperature pattern known as the negative phase of the interdecadal Pacific oscillation

The North Atlantic is one of the key regions, where low-frequency climate variability is formed. However, despite numerous studies related to this topic, some issues still remains unsolved. One of


North Atlantic Ocean control on surface heat flux on multidecadal timescales
Observational evidence is provided that in the mid-latitude North Atlantic and on timescales longer than 10 years, surface turbulent heat fluxes are indeed driven by the ocean and may force the atmosphere, whereas on shorter timescale the converse is true, thereby confirming the Bjerknes conjecture.
Aerosols implicated as a prime driver of twentieth-century North Atlantic climate variability
Systematic climate shifts have been linked to multidecadal variability in observed sea surface temperatures in the North Atlantic Ocean. These links are extensive, influencing a range of climate
Wind Forcing of the Atlantic Thermocline along 32°N at Low Frequencies
Abstract The Bermuda tide gauge record extends back to the early 1930s. That sea level fluctuations there are highly coherent with dynamic height from hydrographic data has two interesting
Mass and volume transport variability in an eddy-filled ocean
Eddy activity in the North Atlantic ocean produces fluctuations in ocean-wide volume transport on the order of 20×106 cubic metres per second, on multi-year timescales. Such background noise makes it
Coherent sea level variability on the North Atlantic western boundary
Interannual to decadal sea level variability on the North Atlantic western boundary is surprisingly coherent over substantial distances stretching from the Caribbean to Nova Scotia. The physical

Observed patterns of wind stress curl and air‐sea heat flux associated with the North Atlantic oscillation (NAO) are used to discuss the response of ocean gyres and thermohaline circulation to NAO

The temperature variability of the Atlantic Ocean is investigated using an eddy-permitting (1/4°) global ocean model (ORCA-025) forced with historical surface meteorological fields from 1958 to 2001.
