Deciphering Freeze–Thaw Dynamics In Rockwalls: A Novel Approach for High Accuracy Regional‐Scale Modeling

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 3, Page 430-448, July/September 2026.
ABSTRACT Using a large and novel array of instruments on five rockwalls in northern Gaspesia, their respective surface energy balances were calculated and their thermal regimes were measured and modeled to depths exceeding the seasonal frost penetration.

Potential patterns of fall armyworm seasonal migration in West Africa modeled with atmospheric trajectory analyses

open access: yesPest Management Science, Volume 82, Issue 7, Page 6509-6517, July 2026.
Migratory fall armyworms in West African breeding habitats showed clear seasonal movements: shifting southwest from January to May, turning northeast in June to July, and returning southwest from August to December. Abstract BACKGROUND The migratory invasive species fall armyworm (Spodoptera frugiperda, FAW) has established year‐round populations in ...

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1172-1187, July 2026.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Contrasting the synoptic drivers of the UK heatwaves of 1976, 2003, 2018 and 2022

open access: yesWeather, Volume 81, Issue 7, Page 212-221, July 2026.
UK summer heatwaves are dictated by the polar jet stream position and sea surface temperature (SST) variability, affecting the Summer North Atlantic Oscillation (SNAO) index. The SNAO can determine and influence the Central England Precipitation (CEP) and Central England Temperature (CET).

Cyclone Ditwah (2025): moderate‐intensity tropical cyclone brings record flooding and damage to Sri Lanka

open access: yesWeather, Volume 81, Issue 7, Page 233-237, July 2026.
Cyclone Ditwah (2025) made landfall in Sri Lanka as a tropical cyclone with only moderate intensity winds (~65–75kmh−1). Yet, its prolonged heavy rainfall also led to landslides and widespread flooding across Sri Lanka and the southern Indian states, with the combined effects of hazards causing impacts totalling 4.1 billion USD. Ditwah is, therefore, a

Climatological Characteristics and Atmospheric Circulation Associated With Three‐Dimensional Heat Wave Types in Middle Europe

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract A novel classification of three‐dimensional heat wave types is applied to Middle Europe over 1979–2022. Heat waves are classified according to their vertical structure of temperature anomalies in the ERA5 reanalysis into near‐surface (HWG), lower‐tropospheric (HWL), higher‐tropospheric (HWH), and omnipresent (HWO).

Advancing Toward Gray Zone: Evaluation of Tropical Cyclones in Key Basins With the 12.5 km High Resolution CAS FGOALS‐f3 Model

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract State‐of‐the‐art climate models are approaching gray‐zone resolutions that can improve the representation of tropical cyclones (TCs), but the extent of these gains remains uncertain. This study evaluates the effect of spatial resolution, particularly near the gray‐zone, using three resolution configurations of the Chinese Academy of Sciences ...

SWOT Observations Constrain a 4D‐Var State Estimate of the California Current System

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides high‐resolution sea surface height (SSH) observations at 2‐km spacing, resolving submesoscale features typical of ageostrophic motions and associated with instabilities. Here, we demonstrate the assimilation of SWOT data into a regional configuration of the MITgcm for the ...

Assessing Dominant Uncertainties in Future Precipitation Projections for a Hurricane‐Prone Region

open access: yesEarth's Future, Volume 14, Issue 7, July 2026.
Abstract Accurate projection of future precipitation remains challenging due to uncertainties in reference data sets, bias correction and global climate models (GCMs). Here, we evaluated these uncertainties across 13 major cities of the U.S. Gulf Coast, a hurricane‐prone region, under 192 historical and future scenarios.

Elevation‐Dependent Permafrost Thaw on the Tibetan Plateau Delays Seasonal Discharge and Poses a Risk of Reduction in Downstream Water Availability

open access: yesEarth's Future, Volume 14, Issue 7, July 2026.
Abstract Global warming and permafrost thaw have significantly altered landscapes and hydrological conditions in permafrost regions. While site‐specific process studies have described hydrological changes during thawing, basin‐scale impact assessments and streamflow modeling remain challenging due to landscape heterogeneity and complex interactions ...
