Assessing Subseasonal Predictions of Stratosphere‐Troposphere Coupling of GraphCast

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract The rapid development of artificial intelligence weather forecasting models (AIWFMs) has revolutionized weather prediction. GraphCast, a leading AIWFM, outperforms state‐of‐the‐art physics‐based numerical models at the surface and in the lower troposphere.

On the definition of height reference surfaces over an arbitrary selected area by means of DFHRS approach

Geodesy and Cartography, 2016
The aim of this study is to analyze the best fitting geoid model for an arbitrary selected area of investigation. The Digital Finite Element Height Reference Surface (DFHRS) method, developed by Hochschule Karlsruhe has been chosen to define the height ...

Compound North American Cold and European Wind Extremes in ERA5 and CMIP6 Historical and Future Simulations. Part 1: Surface Extremes

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract This study investigates the co‐occurrence of North American cold spells and stormy weather in Europe, which we quantify here in terms of extreme wind days (EWDs). We consider both ERA5 reanalysis data and four CMIP6 climate models in the historical period and SSP5‐8.5 scenario. Three distinct regional relationships are identified in ERA5: East

How Lateral Flow Impacts Heavy Rainfall in Complex Terrain: A Composite Analysis Over the Southern Anhui Mountainous Region

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract High‐resolution modeling of terrestrial hydrological processes offers new opportunities to advance the understanding of land‐atmosphere (L‐A) interactions. To investigate the impact of soil lateral flow (LF) on heavy rainfall events in mountainous areas of the Yangtze‐Huai region, we conducted two sets of convection‐permitting WRF simulations ...

The Relationship Between the El Niño‐Southern Oscillation and Extensive Wildfire Area Burned in Contiguous United States Geographic Area Coordination Centers

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We examine the relationship between the El Niño‐Southern Oscillation (ENSO) and extensive wildfire area burned from 1984 to 2022 in nine contiguous United States Geographic Area Coordination Centers (GACCs). The La Niña and El Niño phases of ENSO significantly alter the chances of extensive area burned in several GACCs up to 12 months in ...

Extremes in Southern Hemispheric Zonal Wave‐3 and Their Impact on Antarctic Sea‐Ice Thickness

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Zonal Wave‐3 (ZW3) is a key zonally asymmetric component of the large‐scale extratropical atmospheric circulation, facilitating mass and energy exchanges between middle and high latitudes in the Southern Hemisphere. Despite the crucial role of sea‐ice thickness (SIT) in modulating sea‐ice volume and climate feedbacks, its response to ZW3 ...

Absolute geopotential height system for Ethiopia

, 2010
This study used airborne gravity data, the 2008 Earth Gravity Model (EGM08) and Shuttle Radar Topographic Mission (SRTM) digital elevation data in a ‘Remove-Compute-Restore’ process to determine absolute vertical reference system for Ethiopia. This gives a geopotential height at any isolated field point where there is a Global Navigation Satellite ...

Asian Precipitation Changes in the Past Millennium: Projection of Volcanic Forcing Onto Internal Mode

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Asian precipitation changes over multiple time scales have been extensively studied, yet the relative roles of external forcing and internal variability in shaping the large‐scale Asian precipitation pattern over the past millennium remain underexplored. Here, we demonstrate that the tripolar pattern of decadal precipitation variability across
