Variability of North Sea pH and CO2in response to North Atlantic Oscillation forcing

North Atlantic Multidecadal SST Oscillation: External forcing versus internal variability

A Regime View of the North Atlantic Oscillation and Its Response to Anthropogenic Forcing

The distribution of the daily wintertime North Atlantic Oscillation (NAO) index in the 40-yr ECMWF ReAnalysis (ERA-40) is significantly negatively skewed. Dynamical and statistical analyses both suggest that this skewness reflects the presence of two distinct regimes—referred to as ‘‘Greenland blocking’’ and ‘‘subpolar jet.’’ Changes in both the relative occurrence and in the structure of the r...

An ocean model’s response to North Atlantic Oscillation-like wind forcing

The response of the Atlantic Ocean to North Atlantic Oscillation (NAO)-like wind forcing has been investigated using an ocean-only general circulation model coupled to an atmospheric boundary layer model. A series of idealized experiments was performed to investigate the interannual to multi-decadal frequency response of the ocean to a winter wind anomaly pattern. South of 30 N, the sea surface...

The response of Iberian rivers to the North Atlantic Oscillation

In this study we analyzed the influence of the North Atlantic Oscillation (NAO) on the streamflow in 187 sub-basins of the Iberian Peninsula. Monthly and one-month lagged correlations were conducted to assess the spatiotemporal extent of the NAO influence on Iberian river discharges. Analysis of the persistence of the winter NAO throughout the year was also undertaken, together with analysis of...
