Local Surface and ENSO Forcings Induce Predictable Temperature and Salinity Responses in the Coastal Gulf of Alaska

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract We assess temperature and salinity vertical profile (1970–2025) and mooring time series (1999–2025) data for structure, trends, and variability at northern Gulf of Alaska coastal oceanographic station GAK1 (59° 50.7′N, 149° 28.0′W). The whole water column (0–250 m) is warming, though marginally faster at the surface (+0.21 ± 0.05°C decade−1 ...

Changes in Rainfall Regime: A Case Study in the Piracicaba River Basin, Brazil

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 5, October 2026.
ABSTRACT Changes in precipitation regimes associated with climate variability and climate change pose significant challenges to water resource management, agriculture, and land‐use planning, particularly in socioeconomically strategic regions such as the Piracicaba River Basin, Brazil.

Simulation of Coastal El Niño Events in CMIP6 Models and Its Relationship to Mean‐State and ENSO Biases

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Coastal El Niño (COA) events follow two evolution pathways, remaining in the far eastern Pacific or expanding into basin‐wide El Niño events. Analyzing 55 CMIP6 models, we show that the two pathways are associated with distinct central and eastern Pacific ocean‐atmosphere conditions, and the simulated frequency of each type is linked to ...

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.

Diagnosing Forecast Error Propagation and Large‐Scale Dynamics of Weather Extremes With an AI Weather Model

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Artificial intelligence (AI) weather models can generate fast and accurate weather forecasts, yet they still struggle to predict regional extremes. Exploring error propagation pathways and associated large‐scale dynamics is essential for understanding extreme weather drivers and AI model performance.

Concurrent Eurasian Heatwaves Will Intensify Beyond the Mean Warming

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Concurrent heatwaves over Europe and North China are the most frequent compound heat extremes across the Northern Hemisphere. They are systematically organized by a recurrent teleconnection along the polar front jet over Eurasia. Using observations and large‐ensemble simulations, we show that even after removing the forced warming trend ...

Connection between Barents Sea Ice in May and Early Summer Monsoon Rainfall in the South China Sea and Its Possible Mechanism

Atmosphere
The impacts of Arctic sea ice on climate in middle and high latitudes have been extensively studied. However, its effects on climate in low latitudes, particularly on summer monsoon rainfall in the South China Sea (SCS), have received limited attention ...

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

The Influence of Extratropical Ocean on the PNA Teleconnection: Role of Atmosphere‐Ocean Coupling

Geophysical Research Letters
The Pacific/North American (PNA) pattern is a major low‐frequency variability in boreal winter. A recent modeling study suggested that PNA variability increases through extratropical atmosphere‐ocean coupling, but the effect was not fully extracted due ...

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 ...
