TeleViT1.0: teleconnection-informed vision transformers for subseasonal to seasonal wildfire pattern forecasts

Machine Learning. Earth
Forecasting wildfires weeks to months in advance is difficult, yet crucial for planning fuel treatments and allocating resources. While short-term predictions typically rely on local weather conditions, long-term forecasting requires accounting for the ...

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 ...

Decadal Variability of the MJO and Implications for Southwestern United States Wintertime Precipitation Predictability

Geophysical Research Letters
The Madden‐Julian Oscillation (MJO) is the dominant source of tropical convective activity on intraseasonal timescales and a significant influence on extratropical weather through remote teleconnections.

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 ...

Reduced Distinctiveness of Extreme El Niño Teleconnections in Warmer Climates

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 ...
