Dual drivers of European severe weather: how the NAO and low-frequency climate variability modulate the seasonal transition from shear- to CAPE-dominated tornadogenesis

Weather and Climate Extremes
The climatology of severe convective storms is well documented in the United States, but the large-scale atmospheric drivers of European tornadoes remain less well understood.

Why is the North Atlantic Oscillation More Predictable in December?

Atmosphere, 2019
The prediction skill of the Climate Forecast System, version 2 (CFSv2), for the North Atlantic Oscillation (NAO) is evaluated in three winter months (December, January, and February).

Rapid Global Oxygen Shifts and Delayed OMZ Response: Pulse and Memory of the Pacific Decadal Oscillation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Natural decadal variability often obscures anthropogenic trends in ocean deoxygenation. Using a global observational oxygen reconstruction (1965–2022), we investigate the role of the Pacific Decadal Oscillation (PDO) in modulating decadal oxygen variability.

Subsurface‐Intensified Marine Heatwaves: A Hidden and Intense Warming Threat to Tropical Ocean Ecosystems

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Understanding how the vertical structure of marine heatwaves (MHWs) influences ecosystems remains limited. Here we investigated subsurface‐intensified (Type‐1) and surface (Type‐2) MHWs in tropical oceans using reanalysis data sets. Type‐1 MHWs occur most frequently and are concentrated near the equator, with a threefold greater median ...

Transregional linkages in the north-eastern Atlantic- an 'end-to-end' analysis of pelagic ecosystems [PDF]

, 2009
This review examines interregional linkages and gives an overview perspective on marine ecosystem functioning in the north-eastern Atlantic. It is based on three of the 'systems' considered by the European Network of Excellence for Ocean Ecosystems ...

Monthly values of the North Atlantic Oscillation Index from 1821 to 2000

, 1997
Early instrumental pressure measurements from Gibraltar and the Reykjavik area of Iceland have been used to extend to 1821 the homogeneous pressure series at the two locations.

Interdecadal Changes in the Links Between Late‐Winter NAO and North Atlantic Tripole SST and Possible Mechanism

Geophysical Research Letters
The North Atlantic Oscillation (NAO) and North Atlantic tripole sea surface temperature (SST_tri) are important modes in the atmosphere and ocean over the North Atlantic, respectively. The link between the two is well‐known.

Internal Variability Dominates the Spatial Heterogeneity of Recent Trends in Eurasian Winter Cold Extremes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Eurasia, with its large and climate‐vulnerable population, has experienced increased cold extremes despite global warming, yet their pronounced spatial heterogeneity remains poorly understood. We examine low‐frequency trends in Eurasian cold extremes over recent decades.

The response of freshwater ecosystems to climate variability associated with the North Atlantic Oscillation

, 2003
The North Atlantic Oscillation (NAO) affects the physics, hydrology, chemistry and biology of freshwater ecosystems over a large part of the Northern Hemisphere. Physical impacts of the NAO include effects on lake temperature profiles, lake ice phenology,

Variability of water masses and circulation in the subtropical North Atlantic [PDF]

, 1999
Observations of interannual variability in 18 Water (Talley and Raymer 1982) and Gulf Stream transport (Worthington 1977) motivate an ocean model sensitivity study. The North Atlantic circulation is simulated with a three-dimensional isopycnic coordinate
