Convectively Coupled Equatorial Waves in a Global Storm‐Resolving Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract We show how reducing the fall speeds of rain and ice leads to reduced biases of Convectively Coupled Equatorial Waves (CCEWs) in convection‐resolving configurations of the Icosahedral Non‐hydrostatic Model (ICON). In particular, reducing the fall speeds of rain and ice leads to stronger activity over the wavenumbers and frequencies associated ...

A Near‐Real‐Time Deep‐Learning Solar Flare Forecasting System Supported by SDO/HMI and ASO‐S/FMG Magnetograms

Space Weather, Volume 24, Issue 10, October 2026.
Abstract This study develops and evaluates five deep learning models, including image‐based (CNN, SwinT) and video‐based (CNN‐LSTM, SwinT‐LSTM, Video SwinT), to forecast ≥ ${\ge} $M‐class flares within the next 24 hr using cross‐validation (CV) data sets.

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 ...

The Eddy Flux Transport of the Magnetohydrodynamic Quasi‐Geostrophic Disturbances

Geophysical Research Letters
The classic Eliassen‐Palm (E‐P) flux in the geophysical fluid dynamics is a vector to qualify the eddy momentum and heat flux transport by Rossby waves in the latitude‐height plane. In this investigation, we derive two magnetic E‐P fluxes to quantify the

Intra‐Seasonal Variability of Serial Clustering of Severe European Winter Windstorms

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Clustering of severe European winter windstorms causes large economic loss and social‐environmental impacts. We present a detailed analysis of the intra‐seasonal variability of clustering of severe European winter windstorms based on ERA5 reanalysis, with the focus on impact‐relevant footprints of storm systems for the extended winter season ...

Moist Thermodynamic Processes Leading to the Onset of Moist Tropical Heat Waves

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The plume buoyancy framework used in previous work is applied to understand the processes that lead to moist tropical heat waves (HW). Lag composite analysis applied to land and ocean regions that often experience moist heat waves reveals that buoyancy is typically positive prior to the HW, becoming negative during HW onset due to an increase ...

Influence of Rossby waves on primary production from a coupled physical-biogeochemical model in the North Atlantic Ocean [PDF]

Ocean Science, 2008
Rossby waves appear to have a clear signature on surface chlorophyll concentrations which can be explained by a combination of vertical and horizontal mechanisms.

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 ...
