TLDR
Variability of the North Atlantic Oscillation and the Tropical Atlantic dominate the climate of North Atlantic sector, the underlying ocean and surrounding continents on interannual to decadal time scales as mentioned in this paper.Abstract:
Variability of the North Atlantic Oscillation and the Tropical Atlantic dominate the climate of the North Atlantic sector, the underlying ocean and surrounding continents on interannual to decadal time scales. Here we review these phenomena, their climatic impacts and our present state of understanding of their underlying cause. Copyright © 2001 Royal Meteorological Society.read more

North Atlantic climate variability: The role of the North Atlantic Oscillation
James W. Hurrell,Clara Deser +1 more
TL;DR: In this article, the spatial structure of extratropical climate variability over the Northern Hemisphere and, specifically, focus on modes of climate variability in the extrropical North Atlantic Oscillation (NAO).

Ocean circulation and climate during the past 120,000 years
TL;DR: Evidence implicates ocean circulation in abrupt and dramatic climate shifts, such as sudden temperature changes in Greenland on the order of 5–10 °C and massive surges of icebergs into the North Atlantic Ocean.

A change in the freshwater balance of the Atlantic Ocean over the past four decades
TL;DR: A comparison of salinities on a long transect through the western basins of the Atlantic Ocean between the 1950s and the 1990s is presented, suggesting shifts in the oceanic distribution of fresh and saline waters are occurring worldwide in ways that suggest links to global warming and possible changes in the hydrologic cycle of the Earth.

Decadal Trends in the North Atlantic Oscillation: Regional Temperatures and Precipitation
TL;DR: An evaluation of the atmospheric moisture budget reveals coherent large-scale changes since 1980 that are linked to recent dry conditions over southern Europe and the Mediterranean, whereas northern Europe and parts of Scandinavia have generally experienced wetter than normal conditions.

The Arctic oscillation signature in the wintertime geopotential height and temperature fields
TL;DR: The Arctic Oscillation (AO) as mentioned in this paper is the signature of modulations in the strength of the polar vortex aloft, and it resembles the NAO in many respects; but its primary center of action covers more of the Arctic, giving it a more zonally symmetric appearance.

Teleconnections in the Geopotential Height Field during the Northern Hemisphere Winter
John M. Wallace,David S. Gutzler +1 more
TL;DR: In this paper, a review of existing literature on the subject reveals the existence of at least four such patterns: the North Atlantic and North Pacific Oscillations identified by Walker and Bliss (1932), a zonally symmetric seesaw between sea level pressures in polar and temperature latitudes, first noted by Lorenz (1951), and what we will refer to as the Pacific/North American pattern, which has been known to operational long-range forecasters in this country since the 1950's.

Classification, seasonality and persistence of low-frequency atmospheric circulation patterns
TL;DR: In this article, Orthogonally rotated principle component analysis (RPCA) was used to identify and describe the seasonality and persistence of the major modes of interannual variability.

Annular Modes in the Extratropical Circulation. Part I: Month-to-Month Variability*
TL;DR: In this article, the authors compared the structure and seasonality of the Southern Hemisphere (SH) annular mode and the Northern Hemisphere (NH) mode, referred to as the Arctic Oscillation (AO), based on data from the National Centers for Environmental Prediction and National Center for Atmospheric Research reanalysis and supplementary datasets.
