The Role of ENSO Phase Transition in the Delayed North Atlantic Oscillation Response

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The El Niño–Southern Oscillation (ENSO) is the dominant mode of interannual variability in the Earth system, exerting profound influences on global weather and climate. One notable impact is its ability to generate a dipole‐like sea level pressure anomaly pattern over the North Atlantic, resembling the North Atlantic Oscillation (NAO), with El

Different Last Millennium El Niño Southern Oscillation Sea Surface Temperature Patterns Drive Disparate North Atlantic Tropical Cyclone Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Understanding the relationship between the El Niño‐Southern Oscillation (ENSO) phenomenon and North Atlantic tropical cyclone (TC) activity is critical for both seasonal predictions and future projections of TCs. Unfortunately, the satellite observational era (1970‐present) captures too few El Niño events to fully characterize the response of ...

Land‐Atmosphere Coupling Contributing to Anomalous Rainfall Before the Onset of Australian Monsoon

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract This study applies idealized climate model simulations to investigate the influence of a continent‐sized ponded surface of limited heat capacity on the regional and remote atmospheric state. The analysis focuses on the wet season in northern Australia where precipitation provides critical water resources for agriculture and inland ecosystems ...

Decadal Reversal of Eurasian Winter Temperature Trend Linked to North Atlantic Climate Variability

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The long‐term trend of Eurasian winter surface air temperature has undergone a distinct decadal change, shifting from a pronounced cooling trend between the late 1980s and late 2000s to a subsequent warming trend. This study demonstrates that this trend reversal is partly driven by decadal changes in North Atlantic sea surface temperature (SST)

Atmospheric Variability and Sea-Ice Changes in the Southern Hemisphere

Atmosphere
The Antarctic sea ice concentration (SIC) plays a crucial role in global climate dynamics by influencing atmospheric and oceanic circulation. This study examines SIC variability and its relationship with major climate modes, including the El Niño ...

On the teleconnectivity of the “Arctic Oscillation”

Geophysical Research Letters, 2000
The term “Arctic Oscillation” (AO) has recently been introduced to describe the leading structure of SLP variability over the Northern Hemisphere. A key feature of the AO is its zonally symmetric appearance, with a primary center of action over the Arctic and opposing anomalies in midlatitudes.
