Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Observed Teleconnections in Northern Winter: Subseasonal Evolution and Tropical Linkages [PDF]

, 2016
Teleconnections refer to the climate variability links between non-contiguous geographic regions, and tend to be associated with variability in both space and time of the climate’s semi-permanent circulation features.

Eastern Pacific Corals Track Robust ENSO Variability and Stronger La Niña Events 4,000 Years Before Present

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The interannual El Niño‐Southern Oscillation (ENSO) triggers extreme climate events worldwide. Geochemical proxies in coral skeletons from the eastern equatorial Pacific (EP) track ENSO conditions, constraining its long‐term variance and response to forcing.

Correcting Underestimated Internal Variability Fails to Reconcile Models With Observed Pacific SST Gradient Strengthening

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The equatorial Pacific zonal sea surface temperature (SST) gradient has strengthened since 1980, yet fewer than 1% of CMIP6 simulations reproduce this trend. We test whether underestimated internal variability explains this mismatch. Extreme El Niño events enhance interdecadal variability of the gradient, but CMIP6 models simulate them too ...

Teleconnections and transient eddies

, 2007
The subject of this thesis is the dynamics of teleconnections and mid-latitude stationary eddies, key components of the structure and variability of the extratropical general circulation.

Trans-Pacific ENSO teleconnections pose a correlated risk to agriculture

, 2018
The El Niño Southern Oscillation (ENSO) is a major source of interannual climate variability. ENSO life cycles and the associated teleconnections evolve over multiple years at a global scale.

Reduced Distinctiveness of Extreme El Niño Teleconnections in Warmer Climates

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract In today's climate, extreme El Niño events (e.g., 1982–1983, 1997–1998) generate stronger and eastward‐shifted teleconnections relative to moderate El Niño and La Niña events, leading to distinct North American impacts such as enhanced rainfall over California and warming over northeastern North America.

Seasonal variability and predictability of monsoon precipitation in Southern Africa

Environmental Research Letters
Rainfed agriculture is the mainstay of economies across Southern Africa (SA), where most precipitation is received during the austral summer monsoon. This study aims to further our understanding of monsoon precipitation predictability over SA.

A Review of ENSO Influence on the North Atlantic. A Non-Stationary Signal

Atmosphere, 2016
The atmospheric seasonal cycle of the North Atlantic region is dominated by meridional movements of the circulation systems: from the tropics, where the West African Monsoon and extreme tropical weather events take place, to the extratropics, where the ...

Emergence of Subsurface Warming in the Southern Ocean Gateway Between New Zealand and Antarctica

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We analyze temperature variability in the surface and intermediate layers of the Southern Ocean from 1994 to 2025 using a 30‐year summertime record of Expendable Bathythermograph (XBT) measurements collected along the PX36 line across the New Zealand–Antarctica chokepoint of the Antarctic Circumpolar Current (ACC).
