On the influences of the El Niño, La niña and Atlantic Dipole Paterni on the Amazonian Rainfall during 1960-1998 [PDF]

Acta Amazonica, 2000
The influence of the large-scale climatic variability dominant modes in the Pacific and in the Atlantic on Amazonian rainfall is investigated. The composite technique of the Amazon precipitation anomalies is used in this work.

North Atlantic Interdecadal Variability: Oceanic Response to the North Atlantic Oscillation (1865–1997) [PDF]

Journal of Climate, 2001
Abstract In contrast to the atmosphere, knowledge about interdecadal variability of the North Atlantic circulation is relatively restricted. It is the objective of this study to contribute to understanding how the North Atlantic circulation responds to a forcing by the North Atlantic oscillation (NAO) on interdecadal timescales.

A likely outcome of the sunspot peaks' influence on the North Atlantic Oscillation and Europe in winter

Meteorologische Zeitschrift, 2014
The effect on the North Atlantic Oscillation of 15 sunspot peaks depends on whether the Oscillation is in-phase or out-of-phase with the sunspot peaks. When it is in-phase the anomalies of sea-level pressure adds to the average pressure distribution, and

Decadal cyclone variability in the North Atlantic

Meteorologische Zeitschrift, 2005
The unstable midlatitude ocean-atmosphere coupling motivates the definition of two decadal regimes with distinct implications for the North Atlantic cyclone variability.

Tropical and stratospheric influences on winter atmospheric circulation patterns in the North Atlantic sector

Environmental Research Letters, 2021
Seasonal forecast systems have demonstrated significant skill in forecasting the winter North Atlantic Oscillation (NAO) in recent years. This skill is a result of influences that have remote origins, such as the El Niño-Southern Oscillation or the ...

Tropical Pacific/Atlantic Ocean interactions at multi‐decadal time scales [PDF]

, 2001
Analysis of sea surface temperature (SST) observations suggests a pan‐oceanic interaction between the tropical Pacific and the Atlantic Ocean at multi‐decadal time scales, such that periods of anomalously high SSTs in the tropical Pacific are followed by

Forest productivity in southwestern Europe is controlled by coupled North Atlantic and Atlantic Multidecadal Oscillations

Nature Communications, 2017
The North Atlantic Oscillation (NAO) drives biological responses in terrestrial ecosystems through oscillatory modes of climatic variability. Here, the authors show how landscape scale productivity responses to NAO are contingent upon the Atlantic ...

Northern Hemisphere interdecadal variability: A coupled air-sea mode [PDF]

, 1998
A coupled air–sea mode in the Northern Hemisphere with a period of about 35 years is described. The mode was derived from a multicentury integration with a coupled ocean–atmosphere general circulation model and involves interactions of the thermohaline ...

Scaling Analysis and Evolution Equation of the North Atlantic Oscillation Index Fluctuations [PDF]

, 2004
The North Atlantic Oscillation (NAO) monthly index is studied from 1825 till 2002 in order to identify the scaling ranges of its fluctuations upon different delay times and to find out whether or not it can be regarded as a Markov process.

More extreme summertime North Atlantic Oscillation under climate change

Communications Earth & Environment
Extreme states of the North Atlantic Oscillation in summer can lead to severe weather events such as heatwaves and floods in Europe. But how these extremes evolve in response to climate change remains unexplored.
