Summer North Atlantic Oscillation (SNAO) variability on decadal to palaeoclimate time scales [PDF]
, 2017 The influence of the North Atlantic Oscillation (NAO) on climate in the North Atlantic region has been highlighted over the past few decades. Although most prominent during winter, the NAO is one of the few modes of variability that persist throughout ...

ENSO-driven abrupt phase shift in North Atlantic oscillation in early January
npj Climate and Atmospheric Science, 2023 El Niño-Southern Oscillation (ENSO) teleconnections exhibit a strong dependency on seasonally and intraseasonally varying mean states, leading to impactful short-term variations in regional climate. The North Atlantic Oscillation (NAO)-ENSO relation is a

Is Tropical Atlantic Variability driven by the North Atlantic Oscillation? [PDF]
Geophysical Research Letters, 2002 The role of the North Atlantic Oscillation (NAO) on the genesis of the Tropical Atlantic Variability (TAV) is studied in a coupled ocean‐atmosphere general circulation model using two modeling approaches of partial coupling and partial blocking. It is found that the NAO is not a necessary precondition for the genesis of the TAV although it can enhance ...

A new Rossby Wave-breaking interpretation of the North Atlantic Oscillation [PDF]
, 2008 This paper proposes the hypothesis that the low-frequency variability of the North Atlantic Oscillation (NAO) arises as a result of variations in the occurrence of upper-level Rossby wave–breaking events over the North Atlantic.

Variability of the North Atlantic eddy-driven jet stream [PDF]
, 2010 Much of the atmospheric variability in the North Atlantic sector is associated with variations in the eddy-driven component of the zonal flow. Here we present a simple method to specifically diagnose this component of the flow using the low-level wind ...

Synergistic effects of the winter North Atlantic Oscillation (NAO) and El Niño–Southern Oscillation (ENSO) on dust activities in North China during the following spring [PDF]
Atmospheric Chemistry and PhysicsDust significantly influences global weather and climate by impacting the Earth's radiative balance. Based on reanalysis datasets, this study explores how the North Atlantic Oscillation (NAO) and El Niño–Southern Oscillation (ENSO) during winter impact ...

Increased persistence of warm and wet winter weather in recent decades in north-western Europe
Communications Earth & EnvironmentChanges in weather persistence have important implications for flood risk and regional climate resilience. In recent decades, the winter North Atlantic Oscillation index has shown a sustained shift toward more strongly positive values, exceeding the ...

New insights into decadal climate variability in the North Atlantic revealed by data-driven dynamical models [PDF]
Earth System DynamicsThe Atlantic Multidecadal Variability (AMV) and the North Atlantic Oscillation (NAO) are the dominant modes of oceanic and atmospheric variability in the North Atlantic, respectively, and are key sources of predictability from seasonal to decadal ...

The North Atlantic oscillation in the Atlantic-European SLP
Tellus A: Dynamic Meteorology and Oceanography, 1990 An analysis of the signature of the North Atlantic Oscillation (NAO) in the Atlantic-European sea level pressure (SLP) is presented for observed (German Weather Service) and ECMWF T21 model data. The former time series consists of 1881–1984 January to December fields and the latter of 42 monthly fields from 3 permanent January simulations.

The Relation between the North Atlantic Oscillation and SSTs in the North Atlantic Basin
Journal of Climate, 2004 Abstract The authors use the notion of Granger causality to investigate the relationship between the North Atlantic Oscillation (NAO) index and the sea surface temperatures (SSTs) over the Northern Hemisphere. The Granger causality analysis ensures that any apparent oceanic influence upon the atmosphere (as measured by the NAO) is ...
