Persistent Coastal Temperature Biases in km‐Scale Climate Models Due To Unresolved Oceanic Tidal Mixing

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Recent advances in numerical modeling have enabled km‐scale climate simulations, improving global climate representation and local‐scale projections, critical to climate adaptation strategies. In this context, the present study assesses the performance of such models over coastal shelf seas—key climate‐sensitive regions—in their ability to ...

The GFDL‐CM4X Climate Model Hierarchy, Part I: Model Description and Thermal Properties

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract We present the GFDL‐CM4X (Geophysical Fluid Dynamics Laboratory Climate Model version 4X) coupled climate model hierarchy. The primary application for CM4X is to investigate ocean and sea ice physics as part of a realistic coupled Earth climate model.

Causes of Eurasian Winter‐Cooling During the Late 20th and Early 21st Century

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Pronounced negative trends in wintertime near‐surface temperature have been observed over Eurasia during 1993–2013. It is unclear whether the cooling was due to internal atmospheric variability or forced from either the ocean surface or changes in atmospheric composition. In this study, we use ensembles of atmosphere‐model integrations for the

Reduced Warm Bias in the Surface Southern Ocean by Improved Parameterization of Wind‐Driven Vertical Mixing in an Eddy‐Resolving Coupled Global Climate Model

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The sea surface temperature (SST) in the Southern Ocean (SO) exerts widespread effects on the climate. Yet there is a persistent warm SST bias in the SO across generations of coupled global climate models (CGCMs). Existing literature blames such bias primarily on the deficiencies of model‐simulated atmospheric processes or basin‐scale ocean ...

Sensitivity of the Representation of Polar Lows to Typical Climate Model Resolutions

Atmospheric Science Letters, Volume 26, Issue 9, September 2025.
Climate studies are needed to determine how polar lows affect the ocean circulation. Here, we determine the model resolution needed to represent such polar lows considering grid spacings of 12.5, 25 and 50 km. Their number increases with resolution and the surface winds, associated sensible surface fluxes and precipitation are significantly higher in ...

Unravelling Teleconnection‐Driven Shifts in Precipitation Extremes Over Pakistan Through HighResMIP‐CMIP6 Simulations

International Journal of Climatology, Volume 45, Issue 11, September 2025.
Oceanic and atmospheric indices such as ENSO, PDO and NAO have a substantial impact on Southeast Asia's monsoon, disturbing it with height anomalies and influencing excessive precipitation, particularly, during transitions. Despite general declines in average precipitation relative to the baseline period, HighResMIP‐CMIP6 anticipates increased ...

Impacts of Resolution on Heavy‐Precipitating Storms in Climate Model Hindcasts

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract The present study investigates the impact of horizontal resolutions on heavy‐precipitating storms using the Energy Exascale Earth System Model version2 (E3SMv2) at low (∼100 km, LR) and high (∼25 km, HR) resolutions through short‐range hindcasts.

Greenland summer blocking characteristics: an evaluation of a high-resolution multi-model ensemble [PDF]

Atmospheric blocking is a phenomenon that can lead to extreme weather events over a large region, yet its causes are not fully understood. Global climate models show limitations in representing Northern Hemisphere blocking, especially its frequency, and ...

Downscaled Climate Projections of Tropical and Ex‐Tropical Cyclones Over the Southwest Pacific

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract Reliable projections of tropical cyclones (TCs) and associated impacts remain hampered by both climate model resolution and simulation length. To address this, here we present updated projections of TCs for the southwest Pacific from a high‐resolution downscaled ensemble of CMIP6 models.
