The new indices to describe temporal discontinuity of snow cover on the Qinghai-Tibet Plateau
Snow cover on the Qinghai-Tibet Plateau significantly impacts the climate, hydrology, and ecology of China and East Asia. Current studies mainly use snow cover days to describe its duration, overlooking the snow’s discontinuous nature.

ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.

ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

ABSTRACT Invasive species can fundamentally alter their introduced habitats by changing natural processes and harming native species crucial to functional ecosystems and human needs. Although the number of potential invasive species is large, the suitability of novel locations to support population establishment is limited by both physical and ...

ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Abstract One of the most widely used techniques to measure the unfrozen water content of cryotic soils is to monitor their apparent dielectric permittivity. Paired with an empirical calibration equation or a dielectric mixing model, this measurement, εeff$\varepsilon _{\text{eff}}$, gives an estimate of unfrozen water content in soils.

Does Antecedent Catchment Wetness Explain the Timing of Rainfall‐Runoff Relationship Shifts?
Abstract Annual rainfall‐runoff relationships have been shown to shift during droughts and, in many catchments, not recover, resulting in less runoff per unit of precipitation than prior to the drought. While the cause of these shifts appears to be related to plant water use and subsurface water dynamics, it is still unclear which climatic conditions ...

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 ...
