First Direct Observations of Internal Flow Structures in a Powder Snow Avalanche: Turbulence, Instability and Particle Distribution

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Powder snow avalanches are highly dynamic, multiphase gravity‐driven flows typically composed of a dense basal layer overlain by airborne layers in which snow particles are suspended within a turbulent air phase. Despite extensive work on related systems such as pyroclastic density currents and turbidity currents, all gravity current studies ...

GAM-STTD: a spatiotemporal tropospheric delay correction model for time-series InSAR in complex mountainous regions

International Journal of Digital Earth
Tropospheric delay remains a critical error source in time-series interferometric synthetic aperture radar (TS-InSAR), particularly in mountainous and plateau regions where seasonal stratification and stochastic turbulence coexist.

Stream Temperature Response to Increased Shading Due To Riparian Shrubification in Northern Latitudes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Global warming is causing rapid and profound impacts on northern ecosystems. Shifting precipitation, permafrost thaw, and rapid shrub advance into tundra environments are combining to alter stream temperature in uncertain ways. The expansion and increased abundance of shrub vegetation, termed shrubification, may moderate warming stream ...

Adjustment of a turbulent boundary layer to a 'canopy' of roughness elements

, 2003
A model is developed for the adjustment of the spatially averaged time-mean flow of a deep turbulent boundary layer over small roughness elements to a canopy of larger three-dimensional roughness elements.

Importance of Spatially Continuous Urban Surface Properties in Urban‐Resolving Earth System Modeling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Accurate representation of urban properties and processes at higher resolutions in global modeling systems is essential for advancing our ability to capture the complexities of urban systems and informing effective resilience strategies. However, the prescription of coarse global‐scale urban properties in most state‐of‐the‐art Earth system ...

Study on low-level windshear and turbulence at Hong Kong International Airport by coupling large eddy simulation with mesoscale model

Meteorologische Zeitschrift
Terrain-induced windshear and turbulence are known to be serious threats to airplanes during takeoff and landing. However, it is less known that low-level windshear and turbulence induced by buildings/manmade structures situated near the airport runway ...

Reconstructing China's Natural Streamflow at 1‐km Resolution

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Climate change and intensifying human activities are placing unprecedented pressure on China's water resources, necessitating high‐resolution, naturalized streamflow records for effective management. We develop a 1‐km gridded fully coupled land‐surface‐hydrologic‐hydrodynamic modeling system for China based on the CLHMSv2.0 model.
